As this SIM2Fly was designed for Thai outbound travelers, it follows the rules of Thai sims. You need only top this SIM up 10 Baht per month to get 30 days of validity. This minimum applies to all standard Thai SIM cards. So this of course means you can keep the '''SIM2Fly active for 120 Baht for 1 year! '''Validity also comes with a usage requirement, so make sure you make a call/sms/other usage at least every few months.

As for Topup solutions like MobileTopup.com - they do not charge a high fee, Credit Card and Paypal processors do. The Credit Card processor charge for MobileTopup is 4%, and MobileTopup charges 5%. Do the math on where the fee comes from.

MobileTopup will soon offer lower 20 Baht and 10 Baht amounts for those just interested in keeping validity, without loading too much balance.
