iPhone best on Telus, Rogers or Bell?
I want to get an iPhone 4S in Alberta, Canada. My wife has an iPhone 3G and has had problems with receiving SMS messages on one of these service providers. I.e. her friend will send an SMS message, and they will think it was sent - but my wife's phone never receives it. This has happened consistently on her phone from several different senders. She replaced the SIM card - no change. She replaced the iPhone - no change. Basically, I don't want to deal with these kinds of quirks myself. I've seen that Telus has more cell towers, but have heard the system Rogers uses to distribute cell service is the best setup for the iPhone. Bell might use the same towers as Telus, but I'm unsure. If you can help me figure out what is important in choosing a service provider, please help! Thanks so much.
