langi27: 2 Degrees were smart to keep GSM, I don't know the exact numbers but there are a lot more international roamers with GSM/WCDMA handsets than WCDMA850 handsets. Telcom has missed out on about 3-5 years of GSM roaming revenue, and I also expect the majority of people just want to use Voice and txt only and have no need for high speed internet. GSM is perfect for this. Handsets are dirt cheap and simple to use.
Ahhhhh..............yes XT customers can roam on GSM.
