Second Phone Number — FAQ
Common questions about virtual second numbers.
TwinPhone gives you a virtual second number for your browser or iPhone. No second phone or SIM card is needed. Sign up, choose a US or Canada number, and start making and receiving calls.
Yes. TwinPhone virtual numbers support voice calls and inbound SMS in the browser and on iPhone. Sending SMS isn't supported — the inbox is receive-only.
TwinPhone virtual numbers start from $3.19/month with no long-term contract. Calls are billed separately, pay-as-you-go: $0.02/min to the US and Canada, and every other rate is shown before you dial. No hidden fees.
Yes. TwinPhone offers virtual numbers in the US, Canada and Puerto Rico. Choose a local number in any of them.
Call signalling and media under TwinPhone’s control are encrypted in transit with TLS + SRTP. Your personal number is not shown to the other party — they see your TwinPhone virtual number.
Yes. While the rental is active, the number is yours and renews monthly at the same price. There is no minimum term: cancel anytime in your account.
TwinPhone adds a second number to an iPhone without a SIM or an eSIM: install the TwinPhone app (iOS 17.0 or later), sign in, and rent a US, Canadian or Puerto Rico number from $3.19 a month. Your main SIM number keeps working as before, and the new number lives in the app.
Yes — TwinPhone has an Android app on Google Play, and the same number also works in a current browser on a computer, such as Chrome, Edge, Firefox, Brave, and Safari. The number and the calling balance belong to one account, so they are the same on every device you sign in on.
Yes — when you choose your TwinPhone number in the dialer's "Call from" menu, the person you call sees that number, not your personal one. Without a rented number, calls show a shared TwinPhone number, and showing your own verified mobile number costs $1 a month.
No — a TwinPhone number is a monthly rental, not a disposable burner: it renews at the same price until you cancel it in your account, and it stays yours while you pay. One account can hold up to 3 numbers, so separate numbers for work, selling or sign-ups are possible.
Yes — TwinPhone works as a second business line from anywhere with an internet connection: calls to the US and Canada cost $0.02 a minute, and the rate for every other country is shown before you dial. Team accounts with a shared wallet are set up with you after a demo call.
