On 9 May 2026, Singapore Police announced the results of a SIM registration enforcement operation: between 20 April and 8 May, 7 people were arrested and another 65 were investigated for suspected involvement in registering SIM cards for illicit purposes. This was an enforcement action, not a new rule, and an arrest or investigation is not a conviction. It does point to something everyone getting a Singapore phone number should remember: register a SIM card under your own identity document, and never register one in someone else’s name or on someone else’s behalf. This guide explains how visitors and longer-term residents can legally get a Singapore number.
The short answer: a short-stay visitor can buy a tourist SIM or eSIM with a passport, but should avoid data-only plans if they need to receive text messages. Longer-term residents need a Singapore-issued ID or pass to get a number, and foreign passports cannot be used to register postpaid lines. Singtel, M1 and SIMBA all list a 30-day limit on numbers registered with a passport, and a top-up or extension pack does not remove it, so Zagdim recommends not tying important accounts to that kind of number.
This guide answers:
- How do the tourist plans from Singtel, StarHub, M1 and SIMBA compare, and which can receive text messages?
- What can you register with a passport, how many SIMs can one person hold, and how long does a passport-registered number last?
- What documents do you need for a long-term number if you hold a work, student or dependant pass?
- How do you receive verification codes for banks, Singpass, food delivery and ride-hailing, and how do you keep a number when you leave Singapore?
Key Points
- Who should read this: visitors, workers and students arriving in Singapore, current residents who are leaving or switching carriers, and anyone handling property or a rental in Singapore.
- Registration with ID: the Infocomm Media Development Authority (IMDA) requires SIM cards to be registered with a government-issued identity document.
- Card limits: each person can hold at most 3 prepaid SIM cards across all telcos. From 28 February 2026, new individual postpaid registrations are capped at 10 across all telcos.
- The 30-day passport limit: Singtel, M1 and SIMBA all list a 30-day limit for passport-registered numbers. How you continue beyond 30 days differs by carrier.
- Data-only plans cannot receive texts: M1’s data-only tourist plan cannot send or receive text messages. eSIMs that include voice and text are sold as separate plans, so read the plan details before buying.
- No universal answer on verification codes: Singpass SMS verification needs a Singapore-registered number, and banks, delivery apps and ride-hailing apps each set their own requirements.
- Plans change: Singtel’s original SGD 12 per 30 days hi! plan was removed on 20 July 2026. For new hi! sign-ups from 27 August 2026, ending or porting out within 90 days of activation costs SGD 30.
First, Which Kind of User Are You?
The answer decides which kind of number you can get. The dividing line is whether you hold a Singapore-issued ID or pass, and whether you want to keep the number long term.
| Item | Short-stay visitor | Longer-term resident (work, study, dependant, long-term visit) |
|---|---|---|
| Registration document | Original foreign passport | Singapore-issued ID or pass |
| Numbers to consider | Tourist SIM, eSIM or a prepaid card registered with a passport | Long-term prepaid or postpaid plan |
| Postpaid | Foreign passports cannot be used to register | Depends on each carrier’s documents, Singpass and payment method |
| How long the number lasts | Limited by plan length and the 30-day passport limit | Depends on plan validity and whether you keep paying |
| Singpass | Holding a tourist SIM does not make you eligible | Depends on the official eligibility list for work, student and long-term passes |
How Many SIM Cards Can One Person Hold?
Limits differ for prepaid and postpaid, and both count across all telcos, not per carrier.
- Prepaid: IMDA states a maximum of 3 per person, a limit in place since April 2014.
- Individual postpaid: from 28 February 2026, new registrations are limited to 10. People who already legally held more than 10 before that date can keep them but cannot add more.
- Not affected by the new postpaid limit: corporate plans, and data-only SIMs that cannot send texts or make calls.
Product names and registration categories can differ. For example, Singtel’s current hi! plan documents list the product as postpaid, and StarHub states that its Prepaid Plan counts toward the total of 10. When you sign up, ask the store directly: “Does this line count as prepaid or postpaid on the registration?”
Comparing Plans From the Four Carriers
The four carriers’ tourist plans range from SGD 10 to SGD 30, and they differ in whether they include calls and texts. The details below come from official sources checked on 30 October 2026 and are list prices in Singapore dollars. Plans and data allowances change often, so rely on the page shown at the time you buy.
| Carrier and plan | Price and validity | Main data | Calls and texts | Where to buy |
|---|---|---|---|---|
| Singtel hi! Tourist | SGD 10 / 7 days | 500GB shared across Singapore, Malaysia, Indonesia, Thailand and Hong Kong | Not included initially; you must activate at a designated hi! retailer in Singapore with your passport | Singtel website, authorized hi! retailers |
| Singtel hi! Tourist | SGD 15 / 30 days | 500GB shared across the regions above, plus 18GB Asia-Pacific and 8GB global roaming | Same as above | Same as above |
| Singtel hi! Tourist | SGD 30 / 30 days | 1TB for Singapore, ASEAN and Hong Kong, plus 100GB Asia and 18GB global roaming | Same as above | Same as above |
| StarHub 4G Tourist | SGD 12 / 30 days | 300GB local, plus roaming allowances in selected destinations | Unlimited local calls and texts | eSIM on the website; physical SIM, see below |
| StarHub Tourist Core | SGD 15 / 30 days | 300GB local, plus 30GB Asia-Pacific and 200GB roaming in selected Southeast Asian destinations | Unlimited local calls and texts | Same as above |
| StarHub Tourist Plus | SGD 30 / 30 days | 400GB local, plus 95GB Asia-Pacific and 300GB roaming in selected Southeast Asian destinations | Unlimited local calls and texts | Same as above |
| M1 entry tourist SIM | SGD 12 / 30 days | 500GB | 500 minutes of local outgoing calls, 100 local texts | SIM and eSIM; the retail FAQ still lists a 15-day product at the same price, so check the validity when you buy |
| M1 data-only tourist SIM | SGD 13 / 30 days | 500GB | Cannot make or receive calls, and cannot send or receive texts | SIM and eSIM |
| M1 tourist SIM with calls | SGD 14 / 30 days | 600GB | 500 minutes of local outgoing calls, 50 local texts, free local incoming calls | SIM and eSIM |
| SIMBA prepaid | SGD 10 / 30 days | 500GB shared across Singapore, Malaysia, Indonesia, Thailand and Hong Kong, plus 12GB Asia-Pacific and 3GB global roaming (includes promotional extras) | Confirm the plan contents before buying | Service centers or dealers |
Three points to keep in mind when reading the table:
- Big data figures usually need unpacking. A 500GB or 1TB figure may be shared across several countries or may include promotional extras. Do not assume the full amount is usable everywhere.
- Check the calls and texts column first if you need to receive SMS. M1 sells both plans that can receive texts and plans that cannot on the same page. Singtel’s tourist plans only offer calls and texts after activation.
- Singtel’s website and third-party travel platforms sell different products. The table shows the versions sold on Singtel’s own site and through authorized hi! retailers. Prices and contents elsewhere need separate checking.
Long-Term Plans Have Changed Too: Two Singtel hi! Updates
hi! is Singtel’s plan for longer-term residents and is separate from the hi! Tourist plans above. If an older guide has not been updated, note these two points:
- The old price no longer applies. The terms state that the original SGD 12 per 30 days hi! Plan was removed from 20 July 2026.
- Leaving early may cost a fee. For hi! lines newly signed up from 27 August 2026, ending the line or porting out within 90 days of activation costs SGD 30. This cannot be applied directly to every Singtel tourist SIM; fees for other plans are covered below.
For Visitors: Buy Before You Leave or After You Land?
If you want to be online the moment you land, buy an eSIM before departure. If you prefer a physical SIM or in-person help, get one at the airport or at a city outlet. Either way, bring your passport.
Buying an eSIM Before Departure
Some carriers sell tourist eSIMs online before you leave. StarHub’s tourist eSIM can be bought on its website, and you need to provide your passport for verification at purchase. For some M1 eSIMs, the online process requires Singpass, so visitors without Singpass should first confirm that the plan they want can be completed with a passport. SIMBA’s prepaid SIM must be registered at a service center or dealer, and its online postpaid process does not apply to passport holders.
Zagdim recommends asking three questions before you order: can passport verification and activation be completed outside Singapore, which day does the validity period start counting from, and does your phone support eSIM?
Buying a Physical SIM at Changi Airport or in the City
Physical SIMs are sold at Changi Airport and in the city, and the outlets differ by carrier. StarHub’s physical tourist SIMs are sold at Prosegur Change at Changi Airport, designated Changi Recommends counters and authorized retailers. To activate calls and texts on a Singtel tourist plan, you must take your passport to a designated hi! retailer in Singapore. For other carriers’ airport outlets and opening hours, check their websites before you travel.
Documents to Bring
Bring your original passport. Singtel’s prepaid FAQ says foreign visitors can register with their original passport. SIMBA states that foreign passport holders must register its Prepaid Plan at a service center or authorized dealer, show the original, and that photocopies are not accepted. Singtel hi! Tourist is also limited to foreign passport holders.
If someone tells you that you can get a line without a passport, or offers to register one in someone else’s ID for you, do not go ahead. IMDA requires registration with a government-issued identity document.
How Long Does a Passport-Registered Number Last?
Plan around 30 days for any Singtel, M1 or SIMBA number registered with a passport. StarHub’s tourist plans require passport verification, so confirm the registration period at purchase.
| Carrier | Passport registration period | What to do to keep using it |
|---|---|---|
| Singtel prepaid | Passport registration valid for 30 days | Re-register within that period with a Singapore-issued ID or work pass (this FAQ version is older, so confirm for your actual product) |
| M1 | 30 days from the registration date | Update your NRIC or FIN details in the M1 Prepaid App within 30 days; if not updated, all services and the number end from day 31 |
| SIMBA | Up to 30 days for passport cards | The eligibility FAQ requires a Singapore-issued ID. The July 2026 SuperRoam10 plan summary states you can continue by taking the SIM and passport to an authorized center within 30 days, and that this cannot be done through dealers or online. The two documents differ, so confirm with an authorized center |
NRIC and FIN are the ID numbers Singapore issues to residents and pass holders.
For example, a visitor staying in Singapore for two months buys an M1 tourist SIM. They have no NRIC or FIN to update, so the number ends from day 31. Zagdim recommends treating it as a short-term number, avoiding linking it to banks or long-term accounts, and asking M1 before it expires what options remain.
For Longer-Term Residents: Documents, Prepaid or Postpaid, Payment Methods
If you are staying longer, first confirm which pass you hold, then compare each carrier’s document requirements. Minimum ages, accepted passes, remaining validity of documents and payment methods all differ, so you cannot infer one carrier’s rules from another’s.
Which Documents Do You Need?
Each carrier lists its own accepted passes and documents, so check the row for your plan.
| Carrier and plan | Eligibility and documents | Notes |
|---|---|---|
| Singtel hi! | Age 16 or above; Singpass or a document Singtel accepts, such as Employment Pass, S Pass, Work Permit, Dependent Pass or Student Pass | The SGD 15 / 30 days 5G+ plan includes 500GB shared across five locations; local calls and texts are subject to fair-use limits of 3,000 minutes and 5,000 messages respectively |
| StarHub Prepaid Plan | The FAQ requires original proof documents, citing NRIC, ONE Pass, Employment Pass and Long Term Visit Pass as examples; confirm with StarHub whether other passes are accepted | Each purchase is valid for 1 month; some plan changes are not available to passport-registered users |
| StarHub Unlimited+, Platinum, Data Only | Local or foreign users aged 18 or above; a valid Singpass and a Mastercard, Visa or American Express credit or debit card | Without Singpass you do not meet the conditions for this group of plans |
| StarHub Corporate Individual Scheme (CIS) | Proof of employment, a passport valid for at least 6 months, an Employment Pass, ONE Pass or Work Permit valid for at least 6 months, and proof of billing address | Eligibility is reviewed in store |
| M1 prepaid | Self-registration documents include Employment Pass, S Pass, Work Permit, Student’s Pass, Dependant’s Pass, Long Term Visit Pass and other specified passes | Foreign passports are also subject to the 30-day limit |
| M1 Corporate Individual Scheme (CORI) | Employment Pass holders need a passport valid for at least 6 months and an Employment Pass, plus proof of billing address dated within 2 months | These are CORI conditions, not rules for all M1 plans |
| SIMBA SuperRoam | Singapore citizens, permanent residents, and Work Permit, Employment Pass and Long-Term Pass holders aged 16 or above | Check that your pass is on the eligible list before applying |
For M1’s general postpaid plans, ask an M1 store or customer service which document list applies to your pass, and about any deposit and the sign-up process.
Prepaid or Postpaid?
Foreign-passport holders can register only prepaid, while postpaid needs a Singapore-issued ID or pass.
Start with whether you have Singpass, a payment card that works locally, and a complete set of pass documents.
- Prepaid: the card limit is lower. StarHub’s new Prepaid Plan can be topped up and renewed in the StarHub App, or topped up at authorized retailers, AXS and 7-Eleven, and you can set auto-renewal in the app.
- Postpaid: cannot be registered with a foreign passport, and registration through the web requires Singpass. Read the contract, early termination terms and payment methods carefully.
- A note on names: when “prepaid” is a product name, the payment method and the IMDA registration category may not match, so ask which registration category applies.
Can a Tourist SIM Be Converted to a Long-Term Plan?
An M1 tourist SIM can be converted to a postpaid number before it expires, but you must meet the registration and document conditions of the new plan. StarHub states that some plan changes are not available to passport-registered users. Zagdim recommends asking before it expires if you want to keep the same number, rather than waiting for it to lapse.
How Do You Receive Verification Codes for Banks, Singpass, Delivery and Ride-Hailing?
No single SIM guarantees you will receive every verification code. Zagdim recommends confirming three things: what kind of number the service accepts, whether your plan can receive texts, and whether you personally meet the service’s eligibility rules. Singpass is the login tool for Singapore government services; banks and apps each have their own rules.
| Service | Current rule | What it means for you |
|---|---|---|
| Singpass | SMS two-factor authentication accepts only Singapore-registered numbers; if you are overseas you can use the Singpass app or Face Verification instead | Eligibility depends on the documents you hold, with a minimum age of 15; holding a tourist SIM does not make you eligible |
| DBS PayLah! | Requires a Singapore mobile number that matches the bank’s records; people with a DBS or POSB deposit account can register through digibank, and the Singpass route for people without an account is open only to citizens and permanent residents | A Singapore number alone is not enough; it must match the bank’s records |
| DBS phone banking | An SMS verification code can be sent to the mobile number registered with the bank | Update the bank’s records before changing numbers; check other banks separately |
| PayNow | Identifiers can be a mobile number, NRIC or FIN, or a VPA | Having a Singapore SIM does not mean you already have a PayNow account |
| foodpanda | Account details can include a contact number, and the platform reserves the right to send verification codes by SMS or similar messaging apps; its terms do not state that a Singapore number is required | Check which options the app actually offers at registration |
| Grab | Which overseas numbers and tourist SIMs are accepted depends on the app’s sign-up screen and Grab’s official guidance | If you rely on ride-hailing, test the registration with your number before arriving, or confirm with Grab support |
What Does a Data-Only eSIM Not Receive?
A plan that cannot receive texts will not receive any code sent by SMS. M1’s data-only tourist plan states that it cannot make or receive calls or send and receive texts, so it suits plain internet use.
An eSIM is not the same thing as a data-only plan, though. M1 also sells eSIMs that include voice and text, so judge by the plan contents and not by the word “eSIM.” With Singtel tourist SIMs, do not expect to receive verification texts before you complete the designated activation.
Using Your Home Number in Singapore: Roaming
If you want your existing number to keep receiving verification codes from your home bank, first ask your own carrier whether roaming is enabled. Rules vary widely, and the entries below are examples of named plans, not a description of every carrier in that country or territory.
| Your home network | Named example | What to note |
|---|---|---|
| Hong Kong | csl Your Mobile 30-day prepaid SIM | Roaming text messages are listed at HKD 3 each; also check the roaming regions and the card’s validity |
| Taiwan | Chunghwa Telecom | Singapore is on the list of regions where 3G has closed, so you need roaming data and VoLTE enabled, or voice, text and data may not work. eSIM numbers have the same plans as physical-SIM numbers and are not a separate travel data plan |
| Mainland China | China Mobile | Receiving roaming text messages is free, but data, sending texts and calls are not included; international roaming must be enabled first |
| Malaysia | CelcomDigi Traveller SIM | Zone 1, which covers Singapore, has a 7-day, 4GB, MYR 20 plan; receiving texts is free, but sending texts and calls are disabled. This is a travel product, not a rule for every CelcomDigi number |
| Singapore (existing number, traveling abroad) | Singtel postpaid | Apply for AutoRoam or activate Pay-As-U-Roam first, then add an SMSVoiceRoam or DataRoam plan as needed |
Even if you can receive the text, your bank may not approve the login. Zagdim recommends asking your bank before you travel how login and verification work when you are overseas.
Keeping a Number, Expiry and What to Do Before You Leave
Zagdim recommends looking at the three different time limits separately, then deciding whether to top up, renew, port or cancel.
Three Different Time Limits
Three separate limits apply: the plan period, the SIM or number validity, and the ID registration validity.
- Plan period: how long the data and plan can be used, for example 7 or 30 days.
- SIM or number validity: when the number is terminated.
- ID registration validity: for example the 30 days for a passport registration.
More data does not extend the number or its registration. For example, M1’s regular prepaid card lets you buy a 90-day validity extension pack for SGD 5 from the main account balance in the Prepaid App or Portal, with a maximum total validity of 180 days, but this does not lift the 30-day limit on passport registration.
Can You Keep a Number If You Leave Singapore for a Few Months?
Possibly, but it depends on the plan and has to be handled before expiry.
| Plan | Grace period after expiry | What works during the grace period | If you do nothing |
|---|---|---|---|
| StarHub new Prepaid Plan | 120 days | Receiving calls and texts | Number terminated, balance forfeited |
| SIMBA SuperRoam10 prepaid | 21 days after a failed renewal | Receiving calls and texts | Terminated, wallet balance forfeited |
| Singtel hi! | Base SIM validity is listed as 180 days; the plan itself may be shorter | Depends on the plan | Terminated when the SIM validity ends; a terminated SIM cannot be restored, and unused wallet balance cannot be withdrawn |
If you will be overseas, also note:
- Test the payment route first. Being able to top up or auto-renew in an app does not mean your overseas card will go through, or that you can receive the login verification. Zagdim recommends running through the process once before you leave.
- StarHub’s 120 days does not apply to passport-registered tourist plans. It is a rule for the new Prepaid Plan.
- Roaming is not long-term use abroad. SIMBA’s current plan summary says roaming overseas for more than 30 consecutive days may breach its fair-use policy.
- Cancelling auto-renewal does not keep the number. After you stop payments, the number can still expire and be terminated.
There is no guarantee across carriers that a terminated number can be recovered; Singtel hi! states clearly that it will not restore it. Zagdim recommends listing the banks, Singpass and apps tied to the number before it lapses and confirming how to change the number for each. If you are overseas, Singpass lets you use the app or Face Verification.
Switching Carriers and Keeping Your Number
Do not cancel first. StarHub requires the original line to remain active until the port-out is complete.
- Porting to M1: ask to keep your number when you sign up. The port usually happens 1 working day after the SIM or eSIM is activated, and any remaining contract charges from the old carrier may still apply.
- Porting to Singtel hi!: the porting FAQ requires the original number to be an active postpaid line in your own NRIC or FIN name with no outstanding balance. For prepaid tourist cards, confirm separately.
- Porting out an M1 tourist SIM: you can port to another carrier, but it must be done before the SIM expires.
How to Cancel Before You Leave
Cancellation is done through the app or a form, and the notice period and fees differ by plan.
| Plan | What to do | Fees and refunds |
|---|---|---|
| Singtel hi! | Submit termination in the hi! App at least 7 working days before the next scheduled charge | If you give fewer than 7 working days, the next renewal is still charged; where it applies, ending or porting out within 90 days costs SGD 30 |
| SIMBA SuperRoam10 prepaid | Apply through the designated form at least 7 working days before the next renewal | Ending or porting out within 30 days of activation costs an SGD 30 activation fee; amounts already paid and wallet balance are not refunded |
| StarHub no-contract plans (Star Plan, Unlimited+, Platinum, Senior, Data-only) | Cancel under More / Cancel line in the app | No early termination fee; unused service is not refunded |
| StarHub contract handset plans | Per the service contract | The early termination charge is calculated as the discounted monthly fee multiplied by the remaining months of the contract |
For M1’s general postpaid plans and Singtel’s older plans, the cancellation process and fees depend on your service contract. “No contract” does not mean no activation fee, no remaining device installments and no charges still to be billed.
Checklist: What to Ask Before You Buy and Which Words to Watch
Zagdim recommends asking these before buying:
- Does this plan come with a phone number? Can it receive texts? Do I need to activate it in a store first?
- Is the registration prepaid or postpaid, and how many of my allowed cards does it count toward?
- Until what date does the passport registration last, and what can I do before it ends?
- Can this number be linked to the bank and apps I need?
- Is there a grace period after expiry, and can I receive texts during it?
- If I want a long-term plan or to port my number, by what date must I do it?
- Is there a fee for early termination or porting out?
Five phrases deserve a second look:
- “Data only”: a plan that cannot send or receive texts will not receive SMS verification codes.
- “500GB” or “1TB”: check whether it is shared across several locations and whether it includes promotional extras.
- “Top up to keep your number”: check whether a passport registration period applies.
- “No contract”: check the activation fee and any charges before the end of the term.
- “No passport needed” or “I’ll open it in my name”: do not go ahead, and do not lend your own ID to anyone to register a line.
FAQ
Can I get a SIM in Singapore with a foreign passport? How many?
You can get tourist or prepaid plans, but you must show your original passport, and you cannot get a postpaid line. Each person can hold at most 3 prepaid cards across all telcos.
Can a data-only eSIM receive verification codes?
No. A data-only plan that cannot send or receive texts will not receive SMS verification codes. An eSIM is not the same as data-only: M1 sells eSIMs that include voice and text.
Can I use a tourist SIM to get Singpass or link PayLah!?
Holding a tourist SIM does not make you eligible for Singpass. PayLah! requires a Singapore mobile number that matches the bank’s records, and you must also meet DBS’s registration routes.
Can I keep a passport-registered number going by topping up?
No. Singtel, M1 and SIMBA all list a 30-day limit for passport registration, and M1’s SGD 5 extension pack does not lift it. SIMBA’s conditions for continuing refer to different documents, so confirm with an authorized center.
If I leave Singapore for a few months, can I keep my number?
It depends on the plan. StarHub’s new Prepaid Plan has a 120-day grace period and SIMBA’s SuperRoam10 prepaid plan has 21 days; during that time you can receive calls and texts, and after it the number is terminated.
Can a tourist SIM be converted to a long-term plan or ported?
An M1 tourist SIM can be converted to postpaid or ported before it expires, but you must meet the new plan’s conditions. For other carriers, check first. Singtel hi!’s porting FAQ requires the original number to be an active postpaid line in your own name.
Can I get a terminated number back?
There is no guarantee across carriers. Singtel hi! states that a terminated SIM cannot be restored, so Zagdim recommends dealing with it before expiry.
