AIS top up: minimum amount for 2 months more validity?

[henrik2000]

Hello, my AIS prepaid SIM card is still valid until November 27th, 2025. But now I (Western tourist) fly out and will not use the AIS SIM card for 6 months, as I'm abroad. The SIM card will also not be in the phone. Will the card stay valid until I return to Thailand maybe on November 10th, 2025?

 

It is a "Traveller SIM", bought from AIS at the airport.

AND: I would like to get two months more of validity, to be safe, so that the card would stay valid until late January 2026.
– I understand that I must top up at least 300 Baht to get 3 months more of validity.
– I understand that if I top up only 30 or 100 Baht, I would get only 30 days more of validity.

 

Is that correct? What is the minimum Top-Up amount to get at least 2 months more?

I will top up by credit card through the AIS app.

Thanks!

Top up with 30 baht 3 times 

 

You'll get 1 month after each top up

You can add 20 baht via a thai bank app, with 30 days each.

 

Or go to a Boon Term machine, orange kiosk everywhere, and do 10 baht top ups (costs 12 baht) for 30 days each.

2 x 10 baht, obviously.

Thanks, this just worked perfectly. Now Centigrade above recommends topping up by only 10 Baht... Next time then.

 

I even worried if the credit card company smelled fraud when the small sum of 30 Baht is used three times in a row.
