Does anyone know if AIS has a plan with no expiration of validity. If not what is the longest validity I can get?

Thanks

No. 365 days. (I assume you are asking about pre-paid, One-2-Call.)

There are several methods of extending one's validity, either by paying a fee (30 baht for each 30 days) or using a promotional SIM, like the Tesco One-2-Call SIM which gives 60 days for each 50 baht top-up, yielding 360 days for 300 baht. There may be other methods, I recall some in posts over the years. Maybe best to contact them at 1175?
