Upgrading from iPhone 4S to Samsung Galaxy s4 with AT&T?
My family currently has AT&T and we're looking to upgrade our iPhone 4S's to the Samsung Galaxy s4. We were grandfathered into a data plan that AT&T no longer offers. $10/2GB I believe? Anyways, we're ordering the Galaxy's through Costco and it says that the Galaxy s4 requires either the $30/3GB data plan or the $50/5GB data plan. Would AT&T honor our grandfathered data plan or will we have to change to one of their plans that they currently offer? This will make or break whether or not we get the new phones or not.
