I continue to find the prepay AT&T Gophone offers a good value for my casual need/use of cell telephony. But, I wonder if I can buy a "smartphone" device to access/use my existing Gophone account. Here I'm talking about, say, moving my existing SIM card to a low-end simple touch screen telephone. I'd like to simply be able to place/receive voice telephone on the new device, and perhaps "text" on rare occasions. I might want to move forward to doing "email" and even web browsing, but I'd be interested in getting a touch screen smartphone to just do what I now do. Plain old telephone (POT) service, uing my existing account that charges 10 cents a minute for air time. I guess it also has a data based charge, but I have used that so little I didn't notice what the charges were. I see displays at Walmart on AT&T Gophone with a touch screen "telephone". I haven't yet been able to get a clear answer on the ability to simply buy the touch screen telephone to carry on with my existing Gophone account. As for one reason I'd like to continue to use my existing Gophone account is ith has about $300 in prepaid balance. Thanks.
