In my case, it seems my phone1 has a faulty antenna and could not get a strong enough reception signal in certain areas. But on day1 when I swapped the SIM card to phone2, both coincidentally did not have strong reception on that day. Now phone2 work...
This did not work since last week.I have tried many of the things that has been recently posted on this forum. I used another phone, checked the SIM and the result is the same.
I have the same problem possibly due to a Telus outage problem. Calls don't work while data and SMS are fine. You can check if your area may be near the outage areas.https://istheservicedowncanada.com/status/telus/map
