Let’s say you live in an area with terrible cell phone coverage, but you have decent internet. What can you do?
You can sign up with Vonage. It’s ten bucks a month the first year, 25 bucks a month after that. They send you the VOIP equipment to attach to the router, you plug your home phone into that.
Now, when you’re at home, route your cell calls to that number. It’s included with the Vonage plan.
