Cheap Calls to Mobile — FAQ

Honest answers about calling a real mobile over the internet.

Honest answer: no service places calls to a real mobile 100% free — somebody always pays the carrier the termination fee. WhatsApp and Viber calls are free only if the other person uses the same app. TwinPhone is the closest to free for any mobile number: signup is free, and after that you pay only for the minutes you talk — pay-as-you-go from $0.02/min, no subscription.

Open www.twin-phone.com in any modern browser, sign up in ~30 seconds, type the international mobile number (e.g. +44 7xx xxx xxxx) and hit call. The call uses WebRTC inside the browser — there is no app to install, no extension, and no SIM card involved. Works on a laptop, tablet, or phone browser.

No. That's the difference vs WhatsApp/Viber/Telegram — they only work app-to-app. TwinPhone rings the actual mobile number, so the recipient picks up on their regular phone. They never need an account, an app, or any setup.

From TwinPhone today: US mobile from $0.02/min, India mobile from $0.03/min, Vietnam mobile from $0.04/min, UK mobile from $0.04/min, Germany / Mexico / Russia mobile from $0.05/min. Mobiles in Pakistan, Nigeria, and the Philippines run higher ($0.10–$0.18/min) because of carrier termination fees on those networks — but still 10–30× cheaper than US carrier international roaming, which typically charges $1.50–$3.00 per minute plus a daily roaming fee. The exact per-minute rate to the number you dialled is shown before the call connects.

Rates start at $0.02/min and depend on the destination country and whether you call a landline or mobile. The exact per-minute rate is shown before every call connects. No subscription, no monthly fee, no credit expiry. Add credit from $5 and pay only for the minutes you talk.

Yes. Every call leg under TwinPhone's control is encrypted with TLS + SRTP. Adaptive audio keeps the line stable on slow Wi-Fi (airports, hotels). The other side's leg is handled by their carrier as a normal mobile call.

Yes. The call runs in your browser via Wi-Fi, so your device doesn't need its own SIM. A Wi-Fi-only tablet, laptop, or a phone with the SIM removed all work. You also don't need to own a phone number — TwinPhone routes the call out for you.
