@KBK
are you in Manitoba?
The problem likely is a combination of 3G shutdown and the lack of VoLTE compatibility
While your Samsung Galaxy S10 has VoLTE, it is NOT compatible with PM's VoLTE network. You can use the IMEI checker on this page to confirm: https://www.publicmobile.ca/en/on/get-help/articles/volte
Since your phone is not compatible with PM's VoLTE, your phone has been using 3G for voice, but is now affected by the 3G Network Shutdown that has just started in Manitoba:
https://www.publicmobile.ca/en/get-help/articles/3g-shutdown
If you’re using a 3G-only device, your phone will stop working after these dates:
Manitoba (Rural): January 12, 2026
Manitoba (Urban : Winnipeg & Brandon): Starting March 31, 2026
National: Starting March 1, 2027
There is really nothing much you can do other than to get a phone that is compatible with PM's VoLTE network.
iPhones 8 or later, Google Pixel 4 or later, Samsung S22/Flip 2/Fold 2/A15/A35/A55 or later, or other major brands of phones released after 2024 and are designed and sold for the Canadian market should work.
