Add a second number to your phone

Seems pretty amazing. Is anybody using this for long distance calls for work? Instead of skype?
@mackflavelle Have done! Used this to call from Scotland to the Philipines and vice-versa on the regular.
@mackflavelle @nilefrater Its a great app for wi-fi calling when short on data. Calls to other Line2 users are free.
Sorry if this is too basic of a question, but how does it compare to Google Voice?
@itamarro Google Voice lacks many of the features that Line2 has. For example, Line2 allows you to make calls and send SMS over Wi-Fi or cellular network. Google voice only gives you the alternative phone number. Line2 does that and offers voicemail, free messaging to other Line2 users, auto-attendents, calls menus, etc.
@contentrifi Got it, thank you for elaborating.
Line2 has been working on its app for the Apple Watch as well!
Line2 has just partnered with WeWork. Anyone using WeWork for coworking space? The one in Soma looks cool.
Any plans to allow non-US customers to sign up for your service?
