I do not know if you guys are thinking about this but:
Just to share some ideas about roaming who is in charge of this in PM and with our community.
Maybe PM can talk to a third company or a partner that provides roaming and allow us to use that service or customize this service for us.
i.e.: Koodo and Telus provide a lot of possibilities in terms or roaming, it includes packages, addons and Passes.
Maybe PM can "get a deal" with these or any other company and provide this service. Remember if the service is available the people will start using it when they need it.
Just to close the door about "we must pay first for the service before we can use it", PM can set the payment for this service by using vouchers only, to avoid any kind of "mistake or i hit the wrong button".
Idea or comments are very welcome.
I tried to search about roaming in the Public Lab, but i found nothing, maybe i do not know how to search in public lab.
