I've sent some messages to someone on a different carrier (Rogers) and I'm not sure if they were ever received. It's from an iPhone to an iPhone (mine is 5c, not sure what the other one is.) I know for sure when I was with Virgin Mobile just a few days ago they never received my messages, so I was wondering if maybe the same is still happening, and if there was anyway I could check. They have an Alberta area code, which could be causing some problems. (Although we are both in Ontario).
