I had a Samsung Note 10+ (SM-N975U) given to me by a family member, it was on ATT so I went through the steps thru ATT unlock portal to unlock it. It said successful and it accepted the new sim from Metro finally but I still have issues.

1) "4G VoLTE" shows up by the signal but goes away when making a call and I have no data while on the call. Calls go silent and drop sometimes. Sometimes i totally miss calls and people text me to call them, they cant get through.
Data will work when not in a call with "4G VoLTE" visible. It also says "Metro by T Mobile" by the clock.

2) Still has ATT splash screen that I can deal with but i heard its supposed to change to the new simcard carrier's logo ect. Just wanted to note that incase if it helps.

I made sure VoLTE was on in samsung network settings area. Also played with * # * # 4636 # * # * to check preferred network type had LTE in it. Right now its set to LTE/UMTS auto (PRL)
What preferred network type should it be set for Metro PCS?
Anyone have any ideas where to start?

Thanks for your time/help,
Damian
