TrueMove, AIS, DTAC: Did you recently make a switch from one to another? How did you feel the coverage changed? And the download speeds?

 

 

TRUE is simply the best one! AIS is most expensive and hardly delivers (regarding Speed) what you pay for. DTAC is also quite good for calling but the data connection.

 

On some places in the China Town (Klong Thom) you could some seller who sells TRUE Sims, already activated, for a very low price. They having, for example, for THB 50.00 Pre-paid Sims with an amount of THB 3,000 for 10 month (each month up to THB 300.00) for calling, and others. 

I always stick to AIS, as the credits last for 12 months, so even though away most of the year, it is still ready to work on arrival some months later!

AIS...reliable, fast, inexpensive and good customer support if needed.
