I want to replace my handset but also want to stay with the AT&T plan. How can it be done? I want your help to do so. Here, I have been enjoying very hassle free network service of AT&T and just me for any unlocked cell phone for AT&T plan. I think it would be some expensive decision to skip the current service. I would like to spend no more than $95 on unlocked cell phone AT&T this time. Can it be bought from any online portals at the pocket-friendly cost?
