I live in a border town to the US. Everything was fine with my koodoo service when I went over. Since coming back, my phone continues to show that I am in the US. This has happened before and the problem either corrected itself after a little while or the phone would recognize that I was back in Canada after I would reboot it. It's been several hours now and I've rebooted the phone but the service bar is still showing a US carrier. I turned off roaming while in the US but now I can't make any calls or texts without US roaming.
