TwinPhone is a second phone number and international calling app for iPhone and Android. It lets users get a virtual US or Canadian number without carrying another phone or swapping SIM cards.

Make calls over Wi-Fi or mobile data, receive SMS on your TwinPhone number, and view your call history and calling costs. TwinPhone is useful for freelancers, small businesses, marketplace listings, and people who want separate contact details for work and personal use.

The app is free to download. Calling credit is purchased separately, and virtual phone numbers require a paid subscription. An internet connection is required. TwinPhone does not replace your mobile carrier and cannot be used for emergency calls.
