Hi, First up, no using 3G should not have any impact on call quality for either internal UK calls or those made over seas. This is because the difference between 2.5G and 3G, i.e. Traditional GSM verse 3G, is mainly increased band width, this band width as with land lines is used and dedicated to data based content, and not voice signals. So using 3G will speed up everything from sending a text message or picture message, through to using the internet and sending e-mail, but will not effect call quality. In the case of your call to India, it is likely that the carrier network at the other end doesn't have a particually good quality coverage. As for battery, yes using 3G will notably reduce your battery life.

Firstly, if I set my phone to dual mode, will I get a better signal especially when making or receiving international calls? The reason I ask this is because my phone was set to GSM and I tried to make a call to India but the person on the other end could not hear what I was trying to say whereas I could hear them clearly. secondly, does GSM use less battery than 3G. Thanks guys Pritesh and Alpa Thakore E-mail: alprit@xxxxxxxxxxxx Skype name: alprit5 MSN: pritalpa@xxxxxxxxxxx
