I’ve been using 2 SIMs for about 7 years now. Regular post paid True for calling no data and a separate annual True data only unlimited 15mbps at cost of give or take 1800 baht. I’m up for renewal and can’t find the same one under 2600.AIS are similarly priced. If you’ve bought this kind of SIM recently, where did you buy, what price, which network?
my other option is to buy a package on my post paid SIM, but cost is slightly higher.
