2ndLine - Second Phone Number

A separate number for calls and texts

2ndLine - Second Phone Number gives you a second US or Canadian phone number that works over Wi-Fi or mobile data. It is aimed at people who want to keep work, side-business, dating, travel or privacy-related conversations away from their main number without carrying another SIM card or phone.

What it includes

• Choose a US area code for the number you receive.
• Make calls and send texts in the US and Canada through the app.
• Send picture and video messages, with caller ID and call-history support.
• Call more than 230 countries using paid international calling rates.
• Use custom ringtones, vibration settings and backgrounds to distinguish the second line from your primary one.

How it fits into daily use

The app follows the familiar layout of a phone dialer, so it does not require learning a completely different messaging workflow. It can work with the device’s call logs, act as a default dialer and provide a home-screen widget. Quick Reply is useful when you need to answer a message without opening the full app.

Who should consider it

2ndLine suits users who need a practical extra number for regular domestic calling and texting, especially when separating personal and professional communication matters. It is less suitable if dependable service without an internet connection is essential: call quality and availability depend on Wi-Fi or mobile data. The free model is supported by advertising, while international calls are handled separately.

With a 4.15 rating from about 138,500 reviews and more than 10 million installs, it is an established Communication app from TextNow, Inc. The key comparison is straightforward: choose it when an internet-based second line and built-in calling tools matter more than using a carrier-issued number.
