What's this phone about? High-end?
This is the update to the Samsung u740 (Alias). The u750 is the Alias 2. Similar dual hinge, but a different keyboard. I wouldn't be surprised if this phone requires a Nationwide plan. That's what I think, as I don't know the details on this phone.
I think all new upgrades require Nationwide plans. Americas Choice is gone.
Some salespeople might force NW on all upgrades. I was lucky to retain my AC2 plan when I upgraded nearly a year ago, right around the time NW came out. Certain phones will allow you to stay on older plans, except when getting a phone with html browsers, or dashboard. Each upgrade is different. Changing plans does require NW.
