I'm thinking about retiring my ancient 1st gen iPhone and going with something that has no data plan for a while. I don't want to sign a contract, because I'd want to keep that available, in case I decide later to get another smartphone, but it turns out that it's not easy to find cheap, unlocked phones.
I did stumble across [url=http://www.buy.com/prod/motorola-motofone-f3-cellular-phone-bar-2-1-gsm-800-gsm-1900-480-minute/q/sellerid/23093153/loc/111/210194448.html
]this[/url], however, and I may just go ahead and buy it, because I don't need to do a lot of research for a cheap, low feature phone.
Since I'm using the iPhone now, with no removable SIM card, I'm going to have to ask AT&T to activate this new phone, won't I, and presumably pay a fee? For unlocked phones, do I have to worry about any carrier compatibility other than the communications tech, like whether it's GSM or not?
