User blog:Inthaiguy/A note about Thai prepaid validity

Prior to NBTC making a rule that any top up provide minimum 30 days of added validty, Thai Carriers were free to issue any amount of validty they wished based on the users package. i.e. 500 Baht top up may give 180 days on one carrier on a certain plan and 60 days with another carrier on another plan. This was quite confusing and in fact still exists. Topping up 500 Baht today could give 30, 90 or 120 days of validty depending your prepaid plan. There were even top ups that granted no validity. So, in an effort to standarize things, the 'any top up of any value grants a minimum of 30 days' rule went in effect but it does not, however, requrie only 30 days. Thus many prepaid users need only to top up 500 Baht a few times a year. If you are an infrequent user trying only to keep your number alive, then the cheapest way is the 5 or 10 baht per time approach. i.e. you'd only spend 120 Baht and have 360 days added. This is ONLY for users keeping their phone number valid when not in use - like people who travel to Thailand once a year. Any kind of regular prepaid SIM useage has no need for the 10 Baht = 30 day trick, and hece would not be considerd tedious.
