Thailand SIM Card Registration for Tourists: Passport Rules and the 60-Day Limit
Buying a local SIM card is a convenient way to stay connected in Thailand. Whether you are visiting for a holiday, seeing family or preparing for retirement, you will need to complete the mobile provider’s identity-registration process before using a Thai SIM.
For ordinary visiting tourists, the key document is your original, valid passport. If you plan to keep using a tourist SIM for more than 60 days, you must also reconfirm your identity with the provider.
Do Tourists Have to Register a SIM Card in Thailand?
Yes. Thai mobile operators require users to register their identity. For visiting foreign tourists, this normally involves presenting a passport and completing the provider’s verification checks.
Register the SIM in your own name and check that your passport details have been entered correctly. Before leaving the shop, test the connection and ask staff to confirm your number and package expiry date.
What Should You Bring?
- Your original, valid passport.
- Your mobile phone.
- Your SIM card and packaging, if you already have them.
The provider may scan or photograph your passport and carry out further identity checks. Online registration methods vary by operator and product, so follow the instructions for the SIM you purchase.
Where Can You Buy and Register a Thai SIM?
At the Airport
Mobile-network counters at major Thai airports offer tourist packages and registration assistance. This is convenient if you want mobile data immediately after arrival.
At an Official Network Shop
AIS, True and dtac service locations can explain packages, register your SIM and help resolve verification problems. If you are staying for several months, explain your plans before choosing a package.
Through an Authorised Retailer
Some retailers provide SIM registration as well as sales. Confirm that they can complete the required checks before you buy. Registration facilities and available packages differ between locations.
What Happens After 60 Days?
Tourist SIM users who want to continue using their service beyond 60 days from activation must reconfirm their identity with the provider.
This requirement is separate from the expiry of your data package. You may need to renew your package and complete identity verification to keep using the service.
AIS currently offers these options:
- Send your passport number by SMS to 4444161, then follow the verification link in the reply.
- Visit an AIS Shop for assistance.
These instructions apply to AIS. True and dtac customers should follow their own provider’s current instructions and any verification messages received.

Can You Use an eSIM Instead?
An eSIM can be useful if your phone supports it. Check that your device is compatible and unlocked before purchasing.
A local Thai operator’s eSIM follows that operator’s registration requirements. An international travel eSIM may use roaming and have different activation instructions and features.
Before buying, check:
- Whether the package includes data only or calls and SMS.
- Whether it provides a Thai mobile number.
- The data allowance, speed restrictions and expiry date.
- Whether hotspot use is supported.
- Coverage in the areas you plan to visit.
If you need a Thai number for local calls or verification messages, do not assume a data-only travel eSIM will provide one.
Choosing a Package for Your Stay
For a short holiday, compare the package duration with your travel dates. For a longer visit, ask the provider about suitable plans, identity reconfirmation and how to keep your number active.
Prices and promotions change frequently. Check current offers directly with the operator and ask about the total price, included calls, data limits and renewal arrangements.
If you return to Thailand regularly, ask how to preserve your number between trips. Do not assume an old SIM is still active simply because you have kept the card.
What If Your SIM Stops Working?
Contact the mobile provider or visit an official shop with your passport, phone and SIM. Staff can check whether the problem relates to:
- An expired data package.
- Insufficient credit.
- The number’s validity.
- Incomplete registration or identity reconfirmation.
- Your phone settings or network connection.
Frequently Asked Questions
Can I Register Without a Passport?
Ordinary tourists should bring their original, valid passport. Alternative documents exist for certain categories of non-Thai residents, but those arrangements should not be assumed to apply to holiday visitors.
Does Topping Up Extend the 60-Day Limit?
Topping up alone does not replace the identity-reconfirmation requirement for continued tourist SIM use beyond 60 days.
Do All eSIMs Include Calls and a Thai Number?
No. Some international travel eSIMs are data-only. Read the package details before buying.
Who Should I Contact About a Blocked SIM?
Your mobile provider. An official network shop can check registration, identity verification and technical issues.
