I'm heading for Mexico and Panama for the next few months. Telus wants $30 per month to hold my number. I thought about changing my plan to the cheapest one available but it's still $30. Thinking of porting my number to a VOIP, or just canceling my service and restarting with a new number when I get back to Canada. $30 per month seems excessive for absolutely 0 service. Any other options I should look at?
