Temporary suspension whilst away?

You can not suspend your account.
.
You can remove all features and keep only Quebec coverage. However when you put back your features the price might be different ( Launch price would be ended sometimes in April )

You can change your plan to a cheaper one (like no sms, no calls , 1gb) and pay lower while you don't need it. However, be careful because pricing will change in april you might as well keep your plan like it is to keep your lower rate

If you don't mind paying regular prices when you're back, you can remove all services and you will be charged $8 as the minimum cost.
