I can't send or receive text messages

[Mmehrz]

My mobile has dual sim

I was overseas and used a local number in Sim 2

Since I came back to Canada and 

I am not able to send or receive text messages 

I checked the settings and the message centre is "+16475800172"

Not sure what is the issue

@Mmehrz: What do you get when you try to send a text message? Any error? Also you are able to make phone calls correct?

I removed the other Sim

Only public sim is in the mobile

@Mmehrz  Check the sim manger in your phone settings and ensure PM is enabled /set to primary . And the overseas number is not enabled or set to primary and reboot the phone see if that helps
