Best apps for a second phone number

Need a second phone line? There's an app for that. No need for a second phone.


Once upon a time, your mobile phone number functioned as a second private line in addition to your home landline, and peace reigned throughout the land. Today, with so many people discarding their landlines, mobile phones have increasingly become primary phone numbers, with all sorts of issues associated with that. The first and most common problem is privacy: You may not want everyone to have your private cell number, the same way you didn’t just hand out your home number to anyone who asked for it. What can you do if your mobile number is the only one you have? Easy. Get another number.

You don’t have to jump through too many hoops to add a second or even more numbers to your smartphone, and it’s hardly a novel concept: Verizon and T-Mobile have both caught on to this idea for their customers.

Second or multiple phone numbers give you more control over your life by offering either a permanent or burner number — a second line for web signups, travel, business, online ads, and making calls from an anonymous number. As with most things tech, there’s an app for that, and some solutions are even free of charge, at least for a limited time. Here are some reputable apps you can use to protect your main cell phone number from businesses, casual friends from dating apps, strangers from eBay or Craigslist, or to avoid abusive calls without having to purchase a second phone. Only give your real number to people you trust. For everyone else, there’s your backup phone number.


Sideline is a business oriented app that provides a second phone number as well as calling, texting, and voicemail features, designed for workplace collaboration with your team as well as with customers. All calls are cellular and use your existing carrier plan. Texting includes SMS, MMS picture messaging, and group messaging. Pro features include a team number that allows you to split a single number among multiple devices.

The app also lets you build a unique identity with vanity phone numbers, where your name or product is spelled out. You can choose area codes to find an available local number for your region and employ auto reply via text or MMS if your team can’t pick up right away. An enterprise account lets you manage company phone numbers on employee devices. Additional features include custom caller ID so you know which phone number is ringing, business voicemail message and greeting, voicemail to text, and auto voicemail during non-business hours. You can pick a new Sideline phone number and port numbers from a burner number, Google number, Smartline, Line2, or other services.

Sideline is available for a seven-day free trial, after which you can subscribe to a contract-free monthly or yearly plan costing $10 per month, $50 for six months, or $100 per year.

Burner gives you a second line for calling, texting, and picture messaging for routine interactions. It works by intercepting calls on your Burner and routing them to your cell phone so no one can see your real number. You can call, text, and manage contacts from within the app and treat it as a long term second phone number for your business or outside projects. You can create a disposable phone number for dating, sales, deliveries, shopping, or selling items on Craigslist. Integrations with Dropbox, Google Drive, and Slack allow you to archive messages and voicemails, or communicate with your team.

You can create multiple phone numbers, keep them as long as you want — or burn them anytime. Share your Burner with anyone while keeping your new number secret for anonymous texting. Burner is free to download and comes with a seven-day free sample number. Additional phone numbers are available through in-app purchase or subscription. You can use Burner via a prepaid plan or subscription and can change your plan at any time in the U.S. or Canada, except Puerto Rico.
