How to use the 2ndLine?

To get started with 2ndLine, head over to the Google Play store and search for “2ndLine.” Be sure to type it in exactly, as there are a lot of apps that use the words “second line.”

Once you’ve installed the app, 2ndLine asks you to create an account before letting you proceed further and utilize the services (free or otherwise). You’ll need to enter an email address that you have access to, as well as create a password. Remember, as with any service, you’ll want to create a password that is long, and utilizes both upper and lower case letters as well as numbers. For good measure, we also suggest throwing in a special symbol or two as well such as a # or % sign.

Once you choose a password, you have the option to save it to Google SmartLock so you don’t have to remember it. Out of sight out of mind. Nice touch if you’re into that thing.

After that, you’re asked if you want to set up 2ndLine to make and receive calls. Unless you installed the app solely for texting, you’ll want to do this.

If you click “Set Up,” you are asked to give permission for the app to make and manage phone calls, record audio, and access your contacts. Note that this is an invasive “ask” from the app, so be sure you trust the software developers and that you always keep the app up to date so you get all the security updates. That said, the app has to ask for this as do many similar apps in order to function correctly. For example, if the app can’t access your microphone for phone calls, how do you expect the person on the other end to hear you if the mic doesn’t work?

Next, 2ndLine asks if you want a phone number in your location. If you’re using the phone number to call/text local people or businesses this might be a bonus. Alternatively, if you’re using the app to sign up for services you may need to have a local number to verify you are a real person etc.

If you click “Use my location,” the app will ask permission to access your phone’s location. Then you enter your area code and you’re given a list of free numbers to choose from. After that, you’re taken to 2ndLine’s main interface.

Advantages and disadvantages of 2ndLine


  • Completely online, No need to go to the place to rent / buy the SIM card.
  • Unified inbox: send and receive your texts directly via 2ndLine – use 2ndLine as your one-stop SMS texting app!

Verdict: If you need or want a second phone number for texting, 2ndLine seems like a good option. You also need to live in the U.S. or Canada, otherwise, you can’t use the app. The complaints about sound quality are a bit concerning, so if you need to make calls on your second line, you may want to look for a more reliable option.
