Can I drop my cell service and just use Google voice for a phone number?

Episode 1690 (1:35:26)

Grant from White Bear Lake, MN
Google Voice

Grant is thinking of dropping his cellphone and just use Google Voice. Another option is Skype. Leo says that it could work if you use a mobile device that is data only. That's the biggest issue. Tello is one such service. But it depends on how much voice bandwidth you use, as after a set amount, Tello drops to 2G speeds. Voice takes 86kbps, and 2G is 100kbps. So it's possible.
