Welcome to the Fido community!
It is possible you are eligible for a temporary suspension, first, a few criteria need to be met in order to be eligible.
A temporary suspension can not be done online through self-serve on fido.ca, you will need to contact customer support to have it done. When you get back you just need to contact customer support to have the suspension removed.
