Actually, that may be wrong. I remember a while ago Leo mentioned something about 1-2 Call and 7//11 getting into a pissing match, and 7/11 discontinued carryinng 1-2 Call. I don't know, he takes care of that shit, so maybe another poster can confirm?
Then yes, funds you load on the phone expire, and validity length depends on how much you put on the phone. Can't remember what it is, but *530# or something, it costs 30 baht, and gives any funds about to expire another 30 days of validity. You'll get a SMS letting you know what that 3 digit code is.
