Hey @Be_stacey
Access to make changes on Fido.ca is limited when you are not account holder.
To confirm, you want to change the whole account holder's name to your name? Not simply the Caller ID name showing for your number?
If that is the case, there is a procedure to follow for this since we would create a new account in your name and then, transfer your number over.
- First, your friend would have to contact us to authorize you to take over the number.
- Then you would have to contact us for a credit check and to create your new account to complete the Transfer of Responsibility (TOR).
You can have a look here also for additional information.
I hope this clarifies
