Frequently Asked Questions

Can I use an eSIM in Thailand?
Yes. LTE.app eSIMs work in Thailand on compatible eSIM devices including most iPhones (XS and later) and many Android phones released after 2018. Check our device compatibility page for the full list.
When does my Thailand eSIM activate?
Your eSIM activates when you first connect to a local network in Thailand. You can install it at home over Wi-Fi before you travel — the data countdown only starts when your phone connects to a Thailand carrier after you arrive.
Can I use mobile hotspot (tethering) in Thailand?
Yes. Most LTE.app plans for Thailand support mobile hotspot, so you can share your data connection with a laptop or travel companion. Hotspot availability is shown on each plan card.
Can I use my regular SIM and the Thailand eSIM at the same time?
Yes, if your phone supports dual SIM. You can keep your home SIM active for calls and texts while the Thailand eSIM handles data. Most modern iPhones (XS and later) and Android flagships support this — check your phone's specs to confirm.
How fast is the data in Thailand?
LTE.app plans for Thailand provide full 4G LTE speeds — typically 20–100 Mbps in cities — and 5G where available. Data is not artificially throttled; you get full speeds until your allowance is used.
Do I need to show ID to buy a Thailand eSIM?
No ID required. LTE.app Thailand eSIMs do not require a passport scan, local registration, or any documentation. Simply purchase, receive your QR code by email, and scan to install.
Does the Thailand eSIM include a phone number?
No. LTE.app plans for Thailand are data-only — they do not include a local phone number. You can still call and message using internet-based apps like WhatsApp, FaceTime, Signal, or iMessage over your data connection.
Can I buy more data if I run out in Thailand?
Yes. You can purchase an additional plan at any time through the app or website. The new plan becomes available immediately — you will never be left without data mid-trip.
When should I install the eSIM?
Install the eSIM before you travel while you still have a reliable Wi-Fi connection. The data only starts counting when you connect to a local network in Thailand, so installing early costs nothing.
What is the refund policy?
If you used less than 10% of your data and the plan is within 24 hours of purchase, you can request a full refund. Contact support via the app or visit our refunds page.
Will my device work in Thailand?
LTE.app plans for Thailand work on any carrier-unlocked, eSIM-compatible device including iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3a and newer, and most flagship Android phones from 2020 onwards. Your device must be network-unlocked.
Can I transfer the eSIM to another device?
eSIMs are tied to the device they are installed on and cannot be transferred. If you switch devices, you will need a new plan. Contact support if you need help.
