Airalo or AIS tourist eSIM for the cost?
US, 6 Sep. 7-Eleven is registration. AIS vs True is coverage. I need whether a global pack is cheaper than a Thai number.
Thai number vs a travel pack
| If | Lean | Not |
|---|---|---|
| Two weeks, Grab OTP, islands | AIS tourist eSIM if the phone can take it. Storefront listed from 399 THB on 30 Aug 2026 | A 2019 “299” table |
| You refuse a Thai number | Global pack (Airalo class). Quote this week | Assuming it is always cheaper |
| Grab / bank OTP | Thai number is the boring win | Airport Wi-Fi as the whole week |
| Activation fails in the air | Branded counter after immigration | A Facebook QR |
eSIM is the longer page. A Thai operator SIM still needs NBTC registration. A global pack usually has no Thai number. I will not post an Airalo USD.
Phone, days, and if you need a Thai number for OTP.
