On Call: Finding 3G
Q: I currently have an iPhone 3G but I'm considering purchasing the Sony Ericsson C905. This would be my first time using an unlocked phone and I'm a bit skeptical that it will work. What steps do I need to take in order to make the switch go as smoothly as possible? And will I be able to use AT&T's 3G network? - Nacor
A: Buying an unlocked phone needn't be complicated as long as you consider a couple of points. Most importantly, the phone will need to support the GSM bands used in the United States. Since the C905 is a quad-band GSM phone, you'll be able to make calls here without any problem. Just pop in your AT&T SIM card and you can start dialing. Yet, the 3G compatibility is another story. Sony Ericsson makes two versions of the C905, each with support for different 3G bands. The C905i will support only European 3G bands, while the C905a will work with AT&T's 3G network. So when buying your phone, you'll need to make sure you have the correct model.
Once you get the phone, you'll also need to program it with the correct multimedia settings to send picture messages and browse the Internet. The settings are unique to every phone and carrier but you should be able to download them from the support section on Sony Ericsson's Web site.
