Google Voice

The 9 Best Second Phone Number Apps of 2023 (1)

What We Like

  • Full web interface.

  • Free with no ads.

  • Tied to your Google account.

What We Don't Like

  • More data for Google to play with.

  • Web interface is not feature complete.

  • Google could decide to kill it.

Google Voice has a complicated existence. It has been around for a long time, but it also hasn't been updated in a long time. Given Google's history of building and then removing products, take from that what you will. But, the best part of this app is it's completely free.

It's easy to use and it even has a web interface. You can't make calls from the web, but you can send texts and listen to voice messages. Google Voice even comes with a spam filter for messages and voicemails, which can help you sort through them.

Google Voice works with personal Google accounts and Google Workspace accounts in the U.S. and other select markets.

Cloud SIM

The 9 Best Second Phone Number Apps of 2023 (2)

What We Like

  • Less expansive than other options.

  • Free to call/text other Cloud SIM users.

  • Fun interface.

What We Don't Like

  • No free trial at all.

  • Not free to call any non-CloudSIM user.

  • Limited to the U.S., Canada, UK, and Poland.

Cloud SIM is a service that is great if you have a lot of friends using it, but it's not great at all if you don't.Phone calls and texts are charged by the minute or message if you're not messaging a Cloud SIM user. The app's user interface is fun, with a circular set of buttons for accessing various features, but it comes at the cost of being intuitive. Plus, there is no free trial at all; you're either all in, or all out.

The 9 Best Second Phone Number Apps of 2023 (3)

What We Like

  • Uses carrier signal, not VOIP.

  • Easy interface.

  • Port in your existing phone number.

What We Don't Like

  • Only a 7-day trial.

  • No free option beyond 7-day trial.

  • Expensive.

Sideline gives you a second phone number, while still using your carrier's messaging and voice calling minutes.The benefit is there is no uncertainty when it comes to coverage.If your phone has a signal, you can dial out.The app itself is intuitive, but really reliant on back buttons. Your new number includes calling, texting, and voice mail.

The app offers a 7-day free trial, but no other free option after that. An interesting option allows you to port a number from a different phone into Sideline. If you have a second phone already, you can use that number with Sideline and ditch the second phone altogether.

The 9 Best Second Phone Number Apps of 2023 (4)

What We Like

  • Lots of integrations - Slack, Google, Evernote, and more.

  • App lock.

  • Superior privacy.

What We Don't Like

  • User's guide "notifications."

  • No free option.

  • Pesky calls to action.

Burner is exactly like it sounds: it's a burner phone number for you to use, and then burn. When you burn a number, it gets wiped from your phone and taken out of service.

Burner allows you to integrate into a number of different services like Slack, Evernote, and even SoundCloud to automatically share your voicemails publicly or privately. You get a seven-day free trial like many others; there is no free option.

When you first open the app and create a number, you're asked to give it a name. If you don't, you'll be asked again. You will be asked a lot. Also, a set of user guides are preloaded into the app as notifications, which is not ideal.

The 9 Best Second Phone Number Apps of 2023 (5)

What We Like

  • Clean simple interface.

  • Pick a local number for any area.

  • Can use more than one other number.

What We Don't Like

  • No free option.

  • Importing contacts is a hassle.

  • Messaging options are limited.

Flyp allows you to have as many numbers as you want. The catch is, for every number, you pay the same subscription price. However, this is not the most expensive app out there. Like others, you get a 7-day free trial. Overall, the interface is nice and clean and easy to follow. You can pick a number based on any location, which is always nice.

Flyp doesn't seem to have an easy way to access your contacts from your phone, which is surely a bummer. Messaging options are also limited to audio and photos. There's no support for gifs or stickers.

The 9 Best Second Phone Number Apps of 2023 (6)

What We Like

  • Free to use with ads.

  • Web app (with premium.)

  • Works over Wi-Fi.

What We Don't Like

  • OMG there are ads.

  • Interface is clunky.

  • Holy cow, those ads.

FreeTone gives you one free phone number from any area code, and you can use that number if you agree to ads. In most cases, there are at least two ads on the screen at any time; during phone calls, inside your text message thread, in your contacts.

Of course, if you're willing to put up with all the ads, you're in good shape. If you don't or if you want more than one phone number, you'll need to subscribe. You can choose from weekly or monthly subscriptions, as well as buy credits if you don't want a recurring fee. Overall, it's versatile, it has a web app, and it works without a SIM card on Wi-Fi, which is an added bonus.

The 9 Best Second Phone Number Apps of 2023 (7)

What We Like

  • Flexible subscription options.

  • Toll-free numbers.

  • Lots of customization options.

What We Don't Like

  • No free trial.

  • The UI is

  • Pricey, unless you do unlimited.

Hushed is another privacy-focused service that gives you an independent, easily disposable phone number for texting and calling.It comes with a wide variety of options in terms of subscription and payments from per-call/text plans up to unlimited plans. If you go with a per-call or per-text plan, the costs add up pretty quickly.

The user interface definitely leaves something to be desired. Not only is it a dark theme, which some won't mind, but the icons and UI look a little outdated. They're certainly not anything approaching modern or attractive. Texting includes very limited options as well.

One of the coolest features about Hushed is it allows you to register a toll-free number. While it's not as much of a big deal as it would have been even ten years ago. It's still a nice option.

The 9 Best Second Phone Number Apps of 2023 (8)

What We Like

  • Automatically detects your phone number.

  • Port your number.

  • Credit gamification.

What We Don't Like

  • Credits required to call or text.

  • Credit uncertainty.

  • Frequency requirement.

Dingtone is another free app you can use to make calls and texts, but there are some caveats here. Rather than ads, Dingtone has gamified the app using a credit system.You can buy credits if you want. Otherwise, there are various ways you can earn credits by playing games or checking into the app daily. It's an interesting concept, but ultimately a little confusing.

You need credits to make calls and send texts, but it doesn't say how many you need for each. It doesn't say if it's per message, per day, per minute, or something else. Plus, you need to use your number every ten days and maintain a credit balance of at least one, or you could lose it. It's a bit much and it almost makes ads sound desirable.

The 9 Best Second Phone Number Apps of 2023 (9)

What We Like

  • Works over Wi-Fi.

  • Free to use with ads.

  • Lots of options.

What We Don't Like

  • Frequency requirement.

  • Multiple subscriptions.

  • Bad UI.

Text Free is another absolutely free phone number service, with a catch. The catch is, you have to continuously use the phone number or it may be reclaimed. If a number goes unused for more than 30 days, you lose the number.You can pay a subscription to keep the number active even if you rarely use it.

There are also ads everywhere, but for another subscription fee, you can remove them. The app has a navigation system based heavily on the back button, which is never ideal, but it also works over Wi-Fi, so there's no SIM required.
