http://www.dtac.co.th/en/help/faq.html What are the differences between each of the frequencies? • 1800MHz is the basic frequency for voice operations covering the nation and provides clear and easy reception. • 850MHz supports 3G and is able to penetrate dense structures such as buildings and has a wide reach. • 2100MHz is the latest frequency that dtac has auctioned from the NBTC and is the international frequency for 3G. As dtac has 3 signals, bandwidth is widest and is thus able to provide more efficient internet data transmissions.
