I just recently bought a Samsung Galaxy Exhibit 4G from Metro PCS. It is registered on Verizon network I have all my bars, but I try to make a call and it says network busy, txt fail and I don't have any data. I try to search for available networks and Metro PCS, Verizon and Tmobile come up. I try and choose Metro PCS or Tmobile and it says unable to register on network and goes back to Verizon. What can I do?
