Description
2ndLine is a mobile application that provides users with an additional phone number, allowing them to make free calls and send messages, and is accessible on Android devices. This service utilizes your WiFi or data connection to enable an extra line on your phone. To get started, simply download the app, choose a phone number, and you can instantly enjoy unlimited calling and texting from this new line. 2ndLine operates over your device's existing internet connection, facilitating communication with numbers across the US and Canada. Importantly, the recipients of your texts and calls do not need to be users of 2ndLine to interact with you. During the initial setup, you'll be prompted to select an area code from either the US or Canada, after which you can pick a number from a selection available within that area code. It is essential to keep in mind that 2ndLine only offers numbers that are registered in the US and Canada. Should there be no available numbers in your chosen area code at the moment of signing up, the app will allow you to select a number from the nearest area code. This flexibility ensures that you can get a second line even in less populated regions.
Description
TwinPhone is browser-based international calling: a WebRTC softphone that terminates on the PSTN, so you dial real E.164 numbers and the person you are calling answers on an ordinary phone. Nothing has to be installed on their side — no app, no account, no invitation. On your side it runs in Chrome, Edge and Brave, or as a native iPhone app.
How it works: sign up for free, top up a balance with a card, and dial. The exact rate for the number you dialled is shown before the call connects, so there is no guessing between a landline range and a mobile range inside the same country. Rates start at $0.02/min across 145+ destinations.
Pricing is prepaid and per-call. No subscription, no contract, no monthly minimum, no connection fees, no per-seat licence — an account that sits idle costs nothing.
Every call lands in a call log with destination, duration and cost, exportable as CSV. Contacts are stored for quick dialling, and balance, history and account settings live in one dashboard.
Virtual second numbers start at $3.19/mo for US and Canada. Inbound calls and SMS are delivered straight to the browser, which makes them useful for keeping a personal number out of marketplace listings, sign-up forms and verification flows.
On the transport side, media is encrypted with TLS and SRTP, and adaptive audio holds calls together on congested hotel, cafe and airport Wi-Fi instead of dropping them.
For teams, a single shared prepaid wallet covers everyone, with owner and member roles controlling who can invite teammates and who can spend, plus per-member call logs for internal billing.
TwinPhone is operated by a registered company in the Czech Republic.
