if you dont want to lose the number, maybe porting it to google voice?

Then use an old phone with wifi or computer/tablet then use that as the phone while you are at home/office with voip

And or use a prepaid plan and have google voice forward the call to it? If you are currently racking up money on the plan, you *might* be able to freeze the plan until you can get money to pay it off so the payments dont build up
