abroad. Some phones are able to switch between GSM 900,1800,1900
(tri-band) allowing you full coverage in Europe, America and Asia.

several GSM channels at the same time. This may allow speeds up to 58 bps,
far faster than original GSM (9.6bps). For upload HSCSD is limited to half
the speed. This technology is the predecessor of GPRS, which may deliver
up to 115kbs.
