I have to add +1 when I dial or it says number is not in service.

When I call numbers from my contacts, I get a recording saying the number I have reached is not in service. If I call the same number and add +1 it works.

I have been using this phone and Sim card for years without issue. I have tried restarting my phone. And changing my network from LTE to 3G.

It may be caused from the roll out of the VoLTE service.

Here is some more information:

In this help article, it does mention using +1 while roaming for calling.  Maybe some customers need to use that for local call too.  Need further clarification from PM.

Sometimes you have to add +1 to Canadian number. For some regions that is normal.
