This is an iphone issue.  Check youtube.

try this
turn off iMessage, restart your phone
       Start by opening Settings > Messages, and tap the iMessage toggle to turn it off.
Then restart your phone, open Settings > Messages again, and tap the iMessage toggle to turn it back on. Sign out of Apple ID/Apple Account, then sign back in

Yes i can receive calls and text if i message is off. The problem is since the switch with public mobile

maybe a problem you need Apple instead of PM
