I'm guessing there are a few people here that might know something about this... I'm taking a half month trip to the British Isles in February, and I need a cellphone and answers to miscellaneous stuff regarding cellphone use in that area. The cellphone that I've already sorta decided I wanted, not specifically for this trip but in general, is the Treo 650, but I'm open to tri/quadband GSM phone suggestions. The only two features I'm looking for are bluetooth and a camera. So on the matter of actually making/receiving calls and cost... My regular provider is Cingular. Not really interested in switching to Verizon or anything. So how do I make international calls from the UK without being slammed with exorbitant prices? Do I just rent a phone or something there? Do I buy a prepaid SIM card? Or do I just sign up for international roaming and pay that $1.20/minute for calls from Western Europe, or whatever they charge? And GPRS would be nice, even with the 3 cents or whatever it is per kb. I'd be using it maybe once or twice a day at the most, to call family and ibookin' and perhaps to check email and chat for a bit on AIM. Soooo yeah...any advice before I just go out and do whatever? edit: it'll be a trip through england, scotland, wales and ireland, iirc. so something that wont be too much of a hassle would be nice.
