   Most of 3G coverage is only in the center of Bangkok... lol
   
   3G band is mostly seperated into 2 category (as far as phone is concerned) :-
   --> Three 3G/UMTS bands (900/AWS*/2100 MHz) and four GSM radio frequencies (850/900/1800/1900 MHz) [T-mobile US]
   --> Three 3G/UMTS bands (850/1900/2100 MHz) and four GSM radio frequencies (850/900/1800/1900 MHz) [AT&T US]
   You have to choose the right phone to match your service provider.
   
   * AWS band uses microwave frequencies in two segments: from 1710 to 1755 MHz, and from 2110 to 2155 MHz.
   
   3G band is used differently in Thailand, but they don't really tell explicitly publicly much.
   
   >> TrueMove - 850 MHz (HSDPA 850/2100 MHz 7.2Mbps, but only 850 is implemented.)
   >> DTAC - The Thai authorities have yet to issue licenses for 3G services. (Also called UMTS or HSDPA.)
   >> AIS - 900 MHz (HSDPA 900/2100 MHz but only 900 MHz is implemented.)
   >> TOT 3G - 2100 MHz (1965-1980 MHz & 2155 – 2170 MHz are used in practice)
   >> iKool 3G - uses TOT 3G network
   >> iMobile 3GX - uses TOT 3G network

   ขอบคุณค้าบ สรุปว่า นี่ DTAC ห่วยสุดเลยนะ ประมูลสัญญาณคลื่นความถี่ก็สู้เค้าไม่ได้ แถมอ้างว่าทางการยังไม่ให้ license แล้วยังขายได้แพงสุดอีก?
   
   ส่วน 650 AIS นี่เหมือนกับแค่ EDGE/GPRS เลยนะ .. 3G มัน 950 ฿/mo ใช้ได้ 5GB?
