Hey there @YiyangWang,
We do offer the option to temporarily suspend your line for a period of time at a reduced monthly rate. For $7 monthly, your line can be suspended from 2 to 12 months. This ensures that your Fido numbers and current services remain available when you resume your usage. However, to get this offer, customers must be without an agreement.
Have you already had the chance to reach out to us at these channels to get started? Let us know!
