Hey everyone. I have a question about modems. I have this note 3 and have it updated to the Ota lollipop firmware. I have service with cricket which uses att network. I had to get this phone unlocked. I feel as if my service isn't as good as it was when I had an att note 2 with cricket. Anyway would it be advised to flash a modem from the note 3 att vatiant?
