If you have an unused, inactive Verizon or Page Plus branded non-4G phone laying around, another option would be to use Page Plus Cellular to "port-through" to Google Voice. Go to www.pagepluscellular.com
and click on "Activate" in the upper middle of the page. Then click on the right red button to port your number for free. I'm not sure if you would actually need to complete the activation process to get your number ready to port out to GV... if not, then maybe you can use the ESN/MEID from a busted phone.
