Hi. Thanks for the clarification. This clearly shows the restrictions of the SIM card. A +4-5% premium is tolerable.

But just to be sure of the validity requirement:Is a one-time top-up of THB 120 (and an occasional use) sufficient to keep it alive for a year or do you have to top-up at least THB 10 (which you obviously can't do so far via mobiletopup) every month? The latter is much more inconvenient and is mentioned by mobiletopup for AIS SIM cards:

If this is true telling users: just top it up with THB 120 for a year of validity is quite misleading.
