If you bought a SIM card in Thailand, then you may be using it to communicate with friends, and also perhaps to receive SMS alerts about the movement of funds in a Thai bank account or for two-factor authentication on social networks and other sites.

After returning from Thailand, you will most likely want to keep the SIM card and continue using it. But an unpleasant surprise may await you – having already left Thailand abroad, you may find out that the Thai SIM card does not work in other countries!

What you need to know about working with Thai SIM cards abroad

So, let's look at how to prepare for using a Thai SIM card abroad.

The following must be remembered:

  1. By default, international roaming is disabled for Thai SIM cards.
  2. For Thai SIM cards, there is such a thing as a “validity period”. Even a SIM card with a lot of money on the balance may stop working after a while.
  3. If you are going to use a Thai SIM card for calls and Internet access, then you can pre-purchase a roaming service package and save a lot.

This article tells you how to enable international roaming for a Thai SIM card, as well as how to extend its validity.

How to enable international roaming for TrueMove

The TrueMove mobile app (called True iService) does not have a menu to enable international roaming. Also in the TrueMove app, it is not possible to check if international roaming is already enabled.

For this reason, I would recommend that you ask employees to activate international roaming for you when buying a TrueMove SIM card.

To activate international roaming by yourself, dial the following USSD code


and press the Call button on your phone.

If the previous method did not work for you for some reason, then use the following options:

1. Call 1242 and then dial 9-2-1-4-3 or wait for a response from a support person.

2. Visit TrueMove H Shop or True Shop and contact the staff to activate international roaming.

Turning on the roaming service will take up to 24 hours.

How to extend validity a Thai SIM card

For SIM-cards in Thailand there is such a thing as “validity”. This validity period does not depend on the current balance of the phone number, but is extended each time the balance is topped up.

Moreover, if the SIM card has expired, this does not mean that the money is lost. They seem to be blocked. To activate them, you need to replenish your account.

That is, let's say you had 50 baht in your account. The SIM card has expired and has become blocked. After that, you replenished the balance by another 50 baht. As a result of this action, your SIM card will be unlocked, and there will be 100 baht on your balance.

The expiration dates of SIM cards vary for different mobile operators and may depend on the selected tariff or purchased Internet package.

For example, in dtac and AIS, the user is now given 1 year from the last recharge. Previously, only 1 month was given. Note: just in case, double-check this for your tariff! And in TrueMove, only 1 month is given.

You do not need to top up your mobile phone regularly to keep your SIM card valid. For a few baht you can buy an extension of the validity period.

How to extend TrueMove without topping up balance

Go to the “Bills & Usage” tab and select “Buy Validity”.

Select the desired number of additional days of validity.


  • 30 days for 2.8 baht
  • 90 days for 8.41 baht
  • 180 days for 14.02 baht

You can accumulate up to 365 days of SIM card validity.

TrueMove packages for international roaming

Go to the “Extra Pack” tab and scroll through the groups of packages.

Find the “Roaming” package group and enter the name of the country you are traveling to.

Special offers are available for some countries. Packages common to all countries will also be shown.

How to prevent money loss in international roaming. Setting up your phone for international roaming

You can disable mobile internet if your phone is abroad (“Data roaming”). This is a very convenient feature that does not affect the use of mobile Internet within your country. In addition, if you buy a SIM card abroad, you will still be able to use its mobile Internet, since for it the mobile networks of a foreign state will be local.

Go to “Settings”, to do this, slide the curtain down and click the gear icon.

Go to the “Connections” section.

Go to the “Mobile networks” section.

Turn off the “Data roaming” slider.

Now, when you get off the plane and turn off Airplane mode, your phone will not try to connect to the Internet abroad.

But at the same time you will receive all SMS messages and incoming calls.

If you buy a foreign SIM card, then you can use its Internet without disabling the considered function (since mobile networks will be home for a foreign SIM card).

If you purchased a SIM card for mobile data abroad and if your phone supports dual SIM, you can explicitly specify which one should be used for different communication services.

Go to Settings → Connections → SIM manager.

Here you can explicitly select which SIM card should be used for calls, SMS messages and mobile data.
