Whats the Difference Between Dual-Band and Tri-Band and What do I Use in Antigua and Barbuda?
GSM Mobile Technology operates in Antigua on one frequency level – 900 MHz. Dual band means that your phone will work on 900 MHz and 1800 MHz frequency levels. Tri-band means that your phone will work on 900 MHz, 1800 MHz and 1900 MHz frequency levels, for example if you’re traveling to the USA and plan to use your phone, you would need a tri-band phone as they operate on 1900 MHz levels.
