Moto G 2014 phone not detecting Wind Mobile Ca Sim card, after swapping different sim topic

Hello everywhere! I read online that the Moto G 2014 sold by Wind Mobile Canada comes unlocked, so just to test it out I put in a friend's Bell Sim card, which the phone detected right away. Now when I inserted my Wind Sim card back, it does not read it, there is a constant error on the lockscreen: "No Simcard- Emergency Calls only". I have tested my Wind Sim in my wife's Nexus and it works fine. Her Wind sim card, however, does not work in my phone either, but Bell/Fido etc work just fine.

It seems really odd, because my sim card is not defective, neither is the phone. Any suggestions?

I have restarted, turned it off for a while, factory default but no cigar.

Thanks a bunch
