Hello @JinLi96,
Welcome to the community!
It is possible you can do a temporary suspension, first, a few criteria need to be met in order to be eligible.
1. You need to have been with Fido for a minimum of one month and must not be in a contract.
2. The suspension and the monthly suspension fees will take effect on the last day of your current billing cycle.
3. You will have to pay for it up-front unless you have a pre-authorized payment setup.
4. If you are on the Fido Payment Program you will continue to pay your monthly funding amount during the suspension.
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.
See here for the different methods to contact customer service.
