But I now have a UMTS only option, and the phone works perfectly everywhere in our house.
I have called Vodafone many times this year to try and sort out the problems I've had with voice calls when at home. Of course, no one suggested "debranding" the phone but I don't know if they realise how close they came to losing a customer.
I look forward to the day when they have upgraded their network to 3G. And now there is a deadline for this thanks to Telecom.
