Thailand eSIM FAQ
Do I need an eSIM for Thailand?
If your carrier charges roaming in Thailand, a prepaid eSIM is usually the cheapest way to stay connected. Install it before you fly and get data the moment you land, without hunting for a local SIM shop.
How much does an eSIM for Thailand cost?
AskMia plans for Thailand start at $6.08 for 1 GB / 3 days. A one-week trip with 5 GB costs from $11.11, and 10 GB for 30 days costs from $18.04 (USD, excluding taxes).
Is an eSIM better than an airport SIM in Thailand?
An eSIM is installed before you fly, so you have data for maps and ride apps the moment you land, with no queue and no passport registration at a kiosk. Your home SIM stays in the phone for calls and SMS.
Will I keep my phone number?
Yes. The eSIM adds a second data line. Your primary SIM keeps calls and SMS while the eSIM handles data, so you avoid roaming charges without losing your number.
How do I install the eSIM?
After payment you get an email with a QR code. Open your phone's Settings, add the eSIM by scanning it, and you are ready. Installation takes about a minute and can be done before you fly.
Is my phone compatible?
Most phones from 2019 onward support eSIM: iPhone XS and newer, Pixel 3 and newer, and most recent Samsung and Android flagships. Your phone must be carrier-unlocked. Type *#06# on the dial pad: if an EID is shown, your phone supports eSIM.
