iPad Pro network error.
I've been using new iPad pro (cellular+wifi) from few months.
But all on a sudden this device network doesn’t work!
I reset all network settings but still there is a problem of connecting device network.
After installing a sim card the network stay for 3 or 4 seconds then again it turn to no network service.
There is a message in Setting>General>About>Network (PHONE NOT ALLOWED).
Is it for any technical problem?
iPad Pro, iPadOS 14
