Hi there billa,
If you have data services with Fido you should be able to tether (share your data with other devices)
Could you provide more detail so we can better assist you?
For instance, what type of device are you trying to tether with? What steps are you taking to establish the connection?
Do you receive an error message? Was it working in the past?
The more detail you provide the easier it will be for us to help you
