Travel eSIM
eSIM for Thailand
Thailand splits neatly into two connectivity problems: dense Bangkok, where everything from grab rides to street-food payments happens on a phone, and the islands, where you're relying on mobile data between patchy guesthouse Wi-Fi. A travel eSIM covers both without a SIM-counter stop at Suvarnabhumi. It also keeps your US number reachable for messages while you travel.

How eSIM works in Thailand
Thailand supports eSIM widely, with travel plans generally routing through AIS, TrueMove H, or dtac.
Buy the plan, scan the QR code the partner emails you, and install the profile while you're still on Wi-Fi. Switch the line on when you land.
How much data do you need?
Longer stays and island-hopping tend to burn more data than city trips; pick a bundle you can extend if you're staying a month.
Going abroad from the US?
Every S Mobile unlimited phone plan already includes world eSIM data and free calling and texting to 85+ countries — so your everyday plan travels with you before you even add a destination eSIM.
FAQs — travel eSIM in Thailand
Will my phone work with an eSIM in Thailand?
Most recent iPhone, Google Pixel, and Samsung Galaxy models support eSIM, but your phone also has to be carrier-unlocked. Check your phone's settings for an "Add eSIM" or "Add cellular plan" option before you buy, and confirm device compatibility with the partner at checkout.
How do I set up a travel eSIM before flying in Thailand?
Buy from the partner store, then install the eSIM profile while you still have Wi-Fi at home. It stays dormant until you arrive and switch it on, so you land connected without hunting for a SIM counter.

Can I keep my US number while using a travel eSIM in Thailand?
Yes. A travel eSIM adds a data line alongside your existing line, so your US number stays active for calls and texts over Wi-Fi or your regular plan while data runs on the travel eSIM.
Does S Mobile Wireless run the network in Thailand?
No. Travel eSIM data abroad runs on partner networks, not on our US network. Plans are sold and supported by our partner and billed separately from any S Mobile account.
