Hardware differences between Canadian and UK iPhones.

My cousin has recently moved to the UK from Vancouver, Canada and has got himself a Tesco mobile SIM for his iPhone 5.

Texts and iMessages send fine to some overseas numbers (Canadian) but not to others. This happens when on iMessage and SMS. We tried his new UK SIM in my iPhone 5 and messages sent without any trouble at all.

Apple yesterday agreed to replace the phone for him as they were able to reproduce the issue on one of their test phones in store. He needs to go back next week to pick it up as they were out of stock.

However, does anybody know of any reason why this may be? The 'Genius' at Apple had no idea and couldn't offer an explanation as to why it wouldn't send to some Canadian numbers.
 
Can't see how it could be hardware related, as iMessage simply uses your active data connection, if you can get on the internet then iMessage should work. Sounds very odd.
 
Caveat: I moved the other way UK > Canada
But, if he has moved from Canada you may find it is because of the region of the phone (I brought my UK phone here and the SIM worked fine, but messages / internet didn't properly (always thought I was roaming for starters) when I put in a Canadian SIM. I think it was caused by the fact they use different LTE bands. Mine sorted itself out once I used a Canadian SIM with a Canadian bought phone. No problems since.

He took it to Apple and was told by a Genius that he can't think of any reason why it wouldn't send. I know these Genius people are well trained, but I don't think they get in-depth training about this sort of stuff.

Anyway, they agreed to give him a new UK handset which he picked up this week and everything seems fine now he is using his UK SIM in the UK iPhone. I can only imagine it's similar to what you said, regarding LTE. He mentioned that they have LTE and said that could be one reason for the messages not sending.

I wouldn't say that they are well-trained, just they are trained to following a script or a procedure. By doing the same stuff over and over, they will develop a working knowledge of the common issues.

I've done specialist training in data recovery from Apple handsets and also received Apple training in them too, and can categorically state that the Apple training is pretty weak in direct comparison. Most Genius folks couldn't tell you the File System, Partition structure, how SMS work, how a jailbreak affects the device etc etc.
