Do not upgrade your telus mobility account even for a month!
I had two shared 30 plans and was going away so I decided to upgrade my account to the shared 40 plans for a couple of months as I was going to be using airtime away from my local area.
The telus mobility people told me that it was no problem and we could just switch it back when I got back.
I came back and they discontinued the plan that I had and told me that I could switch it back to the shared 30 plans but that I would have to pay more for the same services I was receiving before I left.
It seems that the contract that I signed only goes in the favor of Telus!
There is much more inconvienence with billing and interactions with the people on the phones but this is a word of warning to all.
Telus is like the banks...hands in your pocket constantly.
