Dual Band GSM 900/1800
The Ericsson T28 is a dual band phone, which means that you can use your
phone on two different kinds of networks – the GSM 900 and the GSM 1800
(also called PCN or DCS 1800) systems.
A dual band phone that combines the two standards can use both frequencies.
This increases capacity in densely populated urban areas, and consequently
improves the coverage offered by your network operator. It also offers you
enhanced international roaming, thanks to the additional networks now
available when you are out travelling.
The switching between the two systems is done automatically and seamlessly,
which means that you can use your phone without ever having to consider
