With the E583C you cannot access DTAC's 3G/UMTS network since it is operated at 850 MHz. You would only be ablte to access DTAC's 2G/GSM network which runs at 1800 MHz.

Therefore you should only use i-mobile 3GX/TOT3G or AIS, which may provide better coverage than TOT3G/imobile 3GX: ??????????????????????? 3G Internet ????? | AIS 3G Mobile Internet

Hi inquisitor,
Thanks a lot. I shall try AIS then. Would you mind telling me which AIS pre-paid sim package is suitable for me? I will stay at Bangkok for about 5-6 days.
Besides, where can I buy AIS data sim? Would you mind also teach me how to set the APN? And, how to activate the AIS data sim.
Many thanks,
KIM
