Frequently asked questions

How do I know if my phone is compatible with a Thailand eSIM?

Your device must be carrier-unlocked and support eSIM technology, which includes most modern iPhones and flagship Android models. You can check compatibility by dialing *#06# to see if an EID number appears, or by checking your phone's cellular settings. Make sure your phone is not locked to your home carrier before purchasing.

How much data do I need for a trip to Thailand?

For light browsing, messaging, and navigation using Google Maps, 1–2 GB per day is usually sufficient. Heavy video streaming, social media posting, or remote work will require 3 GB+ per day or an unlimited data plan. Major Thai networks like AIS and TrueMove H offer various fixed and unlimited packages depending on your stay.

When should I install my Thailand eSIM?

You should install the eSIM on your phone a day before your flight or at the airport while connected to a stable Wi-Fi network. Keep the eSIM line turned off until you land in Thailand, then turn it on and enable data roaming. Your plan's validity period typically begins the moment the eSIM connects to a local Thai network.

Will WhatsApp, Instagram, and iMessage still work with a Thailand eSIM?
Yes

all your social media apps and messaging platforms like WhatsApp, Instagram, and iMessage will continue to work normally. When prompted by WhatsApp or iMessage, choose the option to keep your existing home phone number. You will use the eSIM exclusively for mobile data while keeping your accounts unchanged.

Does the Thailand eSIM include a local phone number?

Some Thailand travel eSIMs include a local Thai phone number (+66) with calling credit, while others are data-only packages. Having a local number can be helpful for receiving SMS verification codes or calling ride-hailing services like Grab and Bolt. Check the specific package details before buying to ensure it meets your communication needs.

What should I do if my eSIM fails to connect when I arrive in Thailand?

First, verify that your eSIM line is toggled ON and that 'Data Roaming' is enabled for the eSIM profile in your settings. Try restarting your phone or toggling Airplane Mode on and off to force a connection to local networks like AIS, dtac, or TrueMove H. If you still have no connection, check that your APN settings match the instructions provided in your eSIM order.

Is buying a Thailand eSIM cheaper than standard daily roaming?
Yes

buying a Thailand eSIM is significantly cheaper than using international roaming from your home provider, which often charges $10 to $15 per day. Thailand eSIM plans start at just a few dollars for multi-gigabyte or unlimited options spanning several days. This allows you to access fast local 4G/5G speeds without risking expensive pay-as-you-go bill shock.
