This is a bit off topic, but I switched out of AT&T recently and I'm really happy about it. I was worried about data overages on AT&T and would constantly turn off my data connection and hunt for wifi. There are many prepaid options out there that offer unlimited data (throttled after a certain limit) and my overage fears are gone. I would encourage you to check out prepaid options. What kept me with AT&T so long was the sweet grandfathered 2yr contract I had but now there are no more 2 yr contracts so I started to look around.
For the OP, it sounds like you are in Canada and I'm unfamiliar with the carriers there. I'm not here to try to sell my carrier, but I get 5 lines for $100 out the door with 2.5gb LTE data and unlimited 2g data after that from a carrier I will not name. I also get same coverage as AT&T so nothing changed. I know the data usage problem isn't addressed by this, but the overage fears may be addressed by this. All I am saying is if you are stuck on AT&T or Verizon, take a look around at some of the prepaid options and you may be surprised how much you could save. I wish I did sooner
