@allant If Rogers won't allow you to do this, you do have other options. One is to port the number to a Voice-over-IP service provider, such as VoIP.ms . You can go here to verify whether or not your Rogers phone number can be ported. If it can, set up an account and you can then keep that number active for as little as $ 0.85 per month.
This is a service that should be provided. If Rogers wants to state it is the best cell provider in Canada, this is something it really must support.
