Travel eSIM vs True and dtac eSIM
True and dtac are Thai mobile carriers, and dtac has been combining into True, so check the carrier's current eSIM offering directly; a travel eSIM is an extra data profile for use while travelling.
True and dtac combining: where the confusion comes from
When two carriers combine, brand names, apps, menus and sign-up channels may no longer match older articles or reviews. We do not state the current status of the merger, or any plan or policy, because these can change. Check the carrier's current eSIM or tourist SIM offering on its official channels.
Which app or number should you use?
If you already have a dtac or True number, that number is your primary line. Check with the carrier which brand's app or account you need to manage an eSIM or plan. Our travel eSIM is unrelated to those accounts and numbers, so it does not affect your existing number.
Carrier eSIM vs travel eSIM: roaming versus a data profile
A carrier eSIM is your main SIM in digital form, carrying your number, and using it abroad relies on roaming under the carrier's terms. A travel eSIM is an extra data profile installed alongside your main SIM, with no number, and works for data in the countries the plan covers.
- Living in Thailand with a Thai number: a carrier SIM or eSIM answers that directly
- Travelling abroad but wanting your Thai number for SMS: keep the main SIM and add a travel eSIM for data
- Visiting Thailand: check the carrier's tourist SIM, or choose a Thailand travel eSIM installed before you fly
Typowe sytuacje
A Thai resident flying to Japan may not want to change the main SIM and can simply add a travel eSIM for data while using the Thai number for SMS. A foreign visitor to Thailand may want data ready on landing without queuing at the airport. In both cases, confirm your phone supports eSIM first.

FAQ
Now that dtac is combining with True, does a dtac eSIM still work?+
We cannot confirm the current status. Check directly with True or dtac whether your existing eSIM and number need any action.
Do I use the True or dtac app to manage an eSIM?+
That depends on how the brands and systems are handled during the combination. Check with the carrier; menu names can differ by app version.
Can a travel eSIM replace my True or dtac number?+
No. Our travel eSIM is data-only with no number, calls or SMS, and is meant to run alongside your main SIM.
What should a visitor to Thailand choose?+
Compare a Thai carrier's tourist SIM (check its current terms with them) with a Thailand travel eSIM that you buy on the web and install before you fly.
Can I use a True or dtac eSIM abroad?+
That depends on the carrier's international roaming terms, so check before you travel. A travel eSIM is built for use abroad from the start.
Will installing a travel eSIM stop my existing number working?+
It keeps working normally. A travel eSIM is an extra data-only profile that runs alongside your primary SIM and does not replace it.
