I subscribed to USMobile (Verizon sim) 4 month ago and my oneplus 8 (TMO, IN_2017) was unlocked since day 1. I was able to connect to Verizon network with OOS 12.1.
Then, I upgraded oneplus 8 to OOS 13 and then I noticed that I can no longer connect to Verizon network. No phone call, txt and internet. I took my Verizon sim out and put it in iphone 11 and it work. I borrowed my wife tello (t-mobile) sim and put it in oneplus 8 and it works.
I checked oneplus network unlock status and it remain unlocked. But oneplus 8 (OOS 13) just cannot register itself to Verizon network.
What can go wrong here? Did OOS 13 lock the carrier to t-mobile only?
Or, Verizon did not whitelist oneplus 8 OOS 13 (IN_2017)?
Any idea?
