Before you insult Stacey, as to keeping it real. I think you should keep it real!
Stacey is absolutely correct. When you open an account with any ISP you must give them an active LANDLINE. You may remove your phone in the future, but your line is still active for processing services. I have ComCast too, and do not have an active physical phone, (just cell phones like you) but my line still has a number. This is the only way your ISP can Track & Trace a problem you might have. I only receive a bill from Verizon for $9.99 a month for my jack & line.
I will investigate Magic-Jack that have been advertised & I have been hearing about. So let's keep it real. If you know something we all don't, then enlighten us, and be specific.
Yes, this knucklehead could have used a library, or other resources. I do find it doubtful, because this guy is a total reject, and I don't think he has the smarts, or knows what planet he is on.
