Ouch, a new Galaxy S2 and you can use any services. Was the device working earlier at all or is this the first time you're trying to get up and running? Sounds like the device may not have programmed properly. I'd like check if this is a network or device issue. Please send me your device number, account pin, callback number and address info to Sprintcares@sprint.com Attn: DDS. I'll be able to check services on your device and reach back out to you for a solution.
