Top up airtime for an existing AIS SIM2Fly eSIM

MobileTopup can add airtime credit to an existing AIS SIM2Fly eSIM. We do not sell new SIM2Fly eSIMs.

1. On the eSIM phone, dial *545# to display the Thai mobile number.
2. Visit MobileTopup.com and enter that number with the +66 country code.
3. Select AIS, choose the available airtime amount, and complete payment.

Once airtime is added, you can use it for eligible AIS SIM2Fly data roaming packages. To check the remaining data balance, dial *111*6#. To check airtime credit, dial *121#.
