My friend and I are having problems calling and receiving phone calls. We both have iPhones 4 & 4s. They are Nova Scotia numbers and when we visit Calgary we can't hear the other party that we are calling or they can't hear us, we even can't hear one another. This problem keeps repeating itself whenever we visit Calgary.I did all the trouble shooting with a Koodo staff member over the phone but it never solves the problem. I'm really considering cancelling my number as this is a complete waste of time and money.
