Hello my friends, my name is Raul I love android phones, I just jumped from my old Moto bionic to the droid ultra factory unlocked. I was a Verizon customer for years but I recently got this prepaid T-Mobile sim card for my droid ultra. Data is awesome, I can receive calls but I can not call, it says roaming indicator off, on the APN configuration it is all clear, I don't even have the + button to add new configurations. I reset the phone and I was able to see the + button for few minutes. if you guys can help I will really appreciate it.
Thanks a lot
