Can you use a us cellular phone with alltel?

You can use a us cellular phone with alltel service, but you can't tell alltel that the phone is us cellular. If you do they may tell you they can't allow another service's phone on their network. There is also another problem. If you do get the MEId swapped you may only get US celllular's easyedge instead of your own alltel online store and such. What I mean is, you can't go online and you can't send pictures. I know this because I have an Alltel phone and US Cellular service. I can't access my contacts back up to get my phone numbers and I can't use my music on my microSD as ringtones. So it's possible but you should maybe dig a little bit further to see if you can get more info.
