2ndLine — Free Second Phone Number (APK)

The description of 2ndLine — Free Second Phone Number (APK)

The 2ndLine second phone number app gives you a real US phone number for calls and texts without a second SIM. It runs on your Wi-Fi or mobile data, so you can call and message across the United States and Canada, share photos over MMS, and keep a separate line for work or listings. The file here is the original TextNow build. Quick note before anything else: this is a utility, not a game, so there is no MOD to add and nothing to unlock. Every feature runs on TextNow's own servers.

The APK on this page is scanned for malware and installed on a real Android device by our editors before publishing, we have done this since 2018. Pick your number, and you are ready in a couple of minutes.

What is 2ndLine?

2ndLine is a VoIP app from TextNow, Inc. that gives you a genuine second phone number with a US area code you choose. It works over the internet, either Wi-Fi or your data plan, so it does not touch your SIM or your carrier number. You keep your normal phone as it is, and the app sits on top with its own line for calls and SMS.

People reach for it when they want to split things up. Hand out one number for work and keep your personal one private. Post on a marketplace or a classified ad without exposing your main line. Sign up for apps, or chat on a dating site, with a number you can drop later. It is a clean way to stop giving your real number to everyone who asks.

Key features

Is it free, and what are the limits?

Yes, the basics are free. Your second number, plus calls and texts within the US and Canada, cost nothing when you are on Wi-Fi or data. The app is ad-supported, and a paid subscription removes the ads if they bother you. So the honest picture: free to talk and text at home, with an option to pay only for a cleaner experience.

Two things to know. International calls are not free, they run on a per-minute rate that depends on the country. And your number needs a bit of activity to stay yours. If you go quiet for a long stretch, the number can be released back into the pool, so open the app now and then to hold on to it. There is no "free forever, no strings" promise here, and we are not going to pretend otherwise.

Privacy: why a second number helps

A second line is a simple privacy win. When you sell something, meet someone new, or fill in a signup form, you give out the 2ndLine number instead of your real one. If it ever gets spammed, you have not leaked the number tied to your bank, your family and your main accounts. You can lock the app with a password too, which helps if you share a device.

Be realistic about what this is, though. It is a normal US or Canada phone number linked to your TextNow account, not an anonymity tool. It keeps your primary number out of sight, and that covers most everyday needs, but it is not built to make you untraceable.

How to download and install 2ndLine APK

The download is a single APK, around 150 MB, and it needs Android 9.0 or newer. Everything starts from the button on this page.

1. Tap the green Download APK button at the top of this page. The original file downloads directly, no registration or SMS.
2. Allow installs from unknown sources for your browser or file manager (Settings → Security).
3. Open the file, tap Install, then launch the app and pick your US area code and number.
4. Prefer the store route? You can also grab it from Google Play, since this is the same original build.

New to sideloading? Our APK install guide walks through the same steps with screenshots. One practical point: to set up and use the number properly you need to be reachable from the US or Canada, since that is where the line lives.

2ndLine vs the original TextNow app

2ndLine and the main TextNow app come from the same developer, TextNow, Inc. The difference is framing. TextNow is pitched as your main phone line, while 2ndLine is built to sit as a second number on top of the phone you already carry. If all you want is one extra line for work, ads or signups, 2ndLine is the tighter fit. Browse more communication apps or dig through the wider app catalog if you want to compare options first.
