Bring your own phone issue.
I brought four phones over from Verizon. Three of them worked flawlessly, but my fourth is having issues.
My LG V30 IMEI is not showing in their system. Calls and 3g work, but it refuses to let me connect 4g. I went into the store and called in, but no one can help. I was told its an invalid IMEI and its only a 3g device. The phone came out a few weeks ago, so maybe the system is not updated?
