All I use is a "flip phone". AT&T is the carrier. I really don't like being bothered with carrying a phone around all the time but my friends insist (I live alone). This morning I couldn't find the phone. I like this little phone and bought a spare, for when the current one craps out (my third one). Although I have the spare phone, the current SIM card will have been lost with the lost phone. I asked here a while back, if we could somehow "copy" a spare SIM card, for just such an emergence. You all told me, "NO". So, can/do you "back up" your phone info, and how do you do it? I found the phone, but if I hadn't, I'm assuming I would have had to go the AT&T store in town and get them to "connect" my spare phone. Having a spare updated SIM card would be a lot easier.
