I have same issue on Revvl +5G for past few weeks with Temporary Unlock notice and takes multiple presses on OK to close. What I think is related to the network connection dropping is 2 apps that are preinstalled on the phone (MCM Client and Carrier Hub) which I cannot disable or uninstall. Every few minutes the phone does a “Synching SIM Contacts” and “MCM Client requests processing” action. I see notification that these are running and during that time the phone disconnects from the cellular network. During that time I cannot send/receive calls or texts. TMobile sent replacement phone and new SIM but no change. I also did factory reset (without restore from backup) and same problem. Something is definitely wrong with this model configuration and/or latest update. TMobile sending one more replacement phone though I doubt it will solve the issue. After that, I am going to request that they provide me with a different replacement model to hopefully resolve this issue.
