I spoke with a Supervisor today regarding why I couldn't buy myself a AT&T Blackberry and use it on the network since CellularOne has switched over to AT&T. The Supervisor says that those CellularOne customers who are on special plans through CellularOne ($50 or $99.95 unlimited plans) can't upgrade (not even buy their own phone)and use it on the AT&T network because AT&T is keeping CellularOne user's on their OLD LEGACY system. AT&T hopes that by not allowing CellularOne customers to upgrade their phones will result in them leaving their cheap plans and coming over to more expensive AT&T plans. If your SIM card goes bad your out of luck, as AT&T will not supply you with a new sim card. You will be forced to switch over to AT&T when this ... (continues)
Hate to say it ,but its perfectly legal, its the same thing they did to old At&t wireless customers. They would allow them to keep their plans but would not allow to upgrade unless they switched to cingular. Legally all that is required is to honor the contract in place and nothing more. By taking away sim cards and not allowing upgrades on the old At&t wireless system , they effectively forced people to change over by legal means.
yes, its perfectly legal. at&t has far too much on the line that would go bad for them if they went and did something illeagle. all of the plans that at&t offers are more or less the same price that cellular one offered, the only difference is that at&t does not offer the unlimited plans. the reason you cant buy an at&t phone and place your sim in it is because at&t has made it a practice long ago that they lock their phones so they can only be used on their network.. i think you were mis-informed to some degree, probably by a cellular one employee over the phone and thus the employee was also mis-informed as well.
