I use to my e-sim and local sim ( The shop at T21 help to install it )as well , but now adays roaming pack  is so cheap cannot be brother anymore  

I buy a roaming pack from my local provider in Aus. It’s not too expensive and i know i might get a better deal with a Thai eSim but I’m too lazy to figure out how it works and if I have to somehow switch between two different numbers e.g. if I get 2FA texts to my home number etc.

Oh. I didn't think about Terminal 21. Thanks!

Anyone every pick up from the 7-11 shops?

Sim on arrival ... 1 month unlimited for 999 THB. But that is basically because I am too lazy to get me an e-sim (top floor Terminal 21), which is more convenient if you make repetitive trips and a lot cheaper 

It's been a while since anyone posted on here. Maybe this has been asked in other threads but I'll post here ince the title makes sense. What do you guys do for data in Bangkok these days? I think things may have changed a lot since my last visit two years ago. Back then I think I bought a SIM card from the home and inserted it just before departing the plane upon arrival. In the past, I've also bought a SIM card upon arrival at the Bangkok airport.
