Do I need a landline phone to use Grasshopper?

No, you do not need a landline phone to use Grasshopper. You can forward incoming Grasshopper calls to your cell phone, office phone, or home office, and you can use our mobile and desktop apps to make and receive calls.

If you do have an existing landline, you can use it to make outbound calls with Grasshopper or even have the phone number transferred to Grasshopper
