Mexico calls

[CanadaChris]

The first few days i was in Mexico I could call back to Canada directly using by tapping on the number in My Contacts.

Starting yesterday, I started the calls would not go through and I kept getting a UC2 error message.

Support advised that I reset my network settings.

I did and I could again make calls to Canada, but only if I dialed the Mexico exit country code of 00 before the number

I didn't have to do that the first few days I was here, but now I do. 

I didn't have to before, and I assumed that was because I was calling from my Canadian Public Mobile number to call a Canadian number.

Anyone else have this issue?

Thanks

How do you manually connect to Telcel?  The network just comes up when the phone turns on. Thanks

Dialing formats & network changes can trigger UC2 errors. Resetting network settings help by adapting to local carriers like Telcel or AT&T, but often requires adding international prefixes afterward. 

The initial direct dialing likely worked because your phone auto-treated it as a "domestic" Canada-to-Canada call via roaming, but carrier switches or settings resets switched it to international mode requiring the exit code (00 in Mexico).

Try connect different networks, try manually connect AT&T and Telcel and make calls again

And make calls by dialing +1 in front of the 10 digits number
