I use Republic Wireless. It's really cool! $300 Moto X, $25/mo (or $40 for 4G). Runs calls and texts through wifi, because really, how often are you not around wifi? Still runs when you're not near wifi, without any minute or data caps that I'm aware of. Never had any issues.
I am a Telus user. I went searching for a new contract not too long ago and it made me convinced that there is collusion going on. Rogers, Telus, and Bell were all offering the exact same contracts, with the same prices. I even phoned the Telus Customer Retention department and was told they are no longer able to offer retention incentives anymore.
