A second phone number is a useful thing and can be used to separate your personal life from your business life — or even just used as an extra layer of insulation when interacting with strangers, websites, or just dating. You might think getting a second phone number is difficult and would require swapping out SIM cards or getting a new phone or something similar.

But you couldn’t be more wrong! All you need to do is look at some of the best Android apps and iPhone apps. An app is all you need to add a second line to your smartphone and keep your personal phone number private and available only to those who you really trust. Here are the best apps to use for getting a second phone number.

Vyke

A blend between a second phone number app and a messaging app, Vyke is the app to grab if you’re looking for both a second number and a new chat app. You can pick numbers from a variety of different countries and create up to four different numbers at once. Calling and messaging other Vyke users is free, but it’ll cost you to message and call other numbers through the app, though you can buy a subscription instead of credit if you prefer. Some reviews do mention issues with getting WhatsApp and other services to accept the second phone numbers, though, so keep that in mind if this is your aim.

iOS Android

Onoff

Speed is the name of the game for Onoff, and it claims to be able to get you set up with a second number in seconds. You can choose from a number of different countries to register your second number, and it comes with visual voicemail and even the choice to market yourself as a “VIP number”. However, there doesn’t seem to be an option to create more than one additional number, and some users have complained about calls being dropped. It costs $4 per month or $13 for an entire year.

iOS Android

Numero eSIM

A solid option for business people and frequent travelers, Numero leans on eSIM capabilities to offer some excellent utility when you’re abroad and when you need a second phone number. You can choose from 80+ countries for your second number and use it to register on WhatsApp and other platforms. The eSIM capabilities are equally impressive and offer custom package deals for 12 countries and data in over 150. You can pay a monthly fee for a U.S.-based second number, but anything anywhere else is going to rely on purchased credits, so keep that in mind if you’re intending to use this for an international number.

iOS Android

Phoner

Phoner second phone number app for iOS and Android.

Phoner app has it all: It offers personal and business second phone numbers, reverse phone number lookup, phone call recording, anonymous caller lookup, and private texting and calling. Phoner supports international calling and texting in over 40 countries, SMS and MMS, as well as phone call recording. You get free texting and cheaper calling rates between Phoner users. Make your new phone number long-term for your business or use Phoner as a temporary disposable phone and generate as many numbers as you need. Phoner offers subscription plans starting at $5 per month for premium numbers.

iOS Android

Sideline

Sideline is a business-oriented app that provides a second phone number as well as calling, texting, and voicemail features, designed for workplace collaboration. All calls are cellular and use your existing carrier plan. Texting includes SMS, MMS picture messaging, and group messaging.

Google Voice

If you have a personal Google account, Google Voice will give you a phone number for calling, text messaging, and voicemail that you can use with your smartphone or computer. It will even sync across devices for on-the-go connections and message management. The app automatically filters out spam and blocks designated numbers. You can arrange personalized settings for forwarding calls, text messages, and voicemail. All communications are stored and backed up so you can search your history. Google Voice provides advanced voicemail transcriptions and lets you call international destinations without extra charges for international minutes. Google Voice calls are placed via the app’s access number using standard minutes from your cell plan. Google Voice only works for personal Google Accounts in the U.S. and G Suite accounts in some markets. Text messaging is not universally supported. Updated versions now support marking group messages as spam.

Cloud SIM

If you need multiple phone numbers on your smartphone for international conversations between mobile and landline, Cloud SIM — which offers numbers from the U.S., U.K., Canada, France, and Poland — may be the answer. The service offers low-cost and free rates for calls or text SMS without additional or roaming charges, lets you choose your connection type, and lets you set up your call via either local access (GSM), mobile data, or Wi-Fi to some 200 countries. Cloud SIM facilitates receiving texts and calls to your new number, free text chat between phones worldwide while using Wi-Fi or data, sharing pictures, and using local access from your free minutes while you travel or have no internet. It offers a dedicated voicemail for each separate mobile number. You can buy up to four virtual numbers. New versions let you export and import SMS and chats.

Burner

Burner second phone line.

Burner gives you a second line for calling, texting, and picture messaging. It intercepts calls on your Burner, routing them to your cell phone so no one sees 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 business or projects or create a disposable phone number for dating, sales, deliveries, shopping, or selling items on Craigslist.

Integrations with Dropbox, Google Drive, and Slack let you 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 purchases or subscriptions. 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 in Puerto Rico.
