When you go to the page to signup you should get a pop up to do an online chat about what you're doing. Have you chatted to ask the question about how adapters will be handled?
I did the online chat about a month ago and the rep said I would be charged for the adapters which is why I did not renew my contract at the time. Do you know if they are still doing the loyal customer $15 a month discount that I currently get. I'm trying to keep my monthly cost close to what I already have.
