Australian mobile operator Telstra has launched a new calling solution for mobile phones that enables customers to roam between Telstra's CDMA and GSM networks using one handset and with one main phone number.
The new technology automatically directs voice calls from the CDMA to GSM service where the CDMA service is busy, switched off, out of range or unanswered. Where the GSM service is unavailable, calls to the GSM service will be diverted to a shared Telstra MessageBank.
The Motorola A840 is the first handset in Australia to utilise Telstra's new calling solution. Handsets from other manufacturers may be introduced in the months ahead. To roam on both Telstra's CDMA and GSM networks customers will also need to take up the 2in1 Calling Solution GSM Plan.
The handset combines 800/1900 CDMA, CDMA 1X and 900/1800 GSM, GPRS modes with seamless network switching. The company promisses that with the model A840 users can access the same content over GPRS as they would over a CDMA network.
The new mobile is packaged in a clamshell design with an integrated MP3 player, removable Trans-Flash memory, 2.2-inch colour display, speaker-independent speech recognition, and 1.2 megapixel integrated camera.
This launch coincides with the introduction of several new CDMA network roaming agreements in countries including Hong Kong, Thailand and China.
Telstra's GSM network provides coverage across more than half a million square kilometres and reaches more than 96 per cent of the total Australian population. Telstra's digital CDMA network provides land coverage to more than 1.6 million square kilometres and more than 98 per cent of Australia's population.
