Frequently asked questions
Everything you need to know about TwinPhone.
Honestly, not unlimited-free. App-to-app calls are free only when both people use the same app and are online. With TwinPhone there's no subscription — top up from $10 (about 500 minutes to United States at the lowest rate) and calls start at 0.02 $/min, with no app or SIM. That reaches United States numbers that aren't on an app, and you pay only per minute.
Up to about 500 minutes to United States at 0.02 $/min, the lowest rate there; mobiles can cost more. You top up only what you need — there's no subscription and credit never expires.
