9 Best Second Phone Number Apps in 2025

When you’re running a business, the last thing you want is to use your personal number for your company. Imagine putting your private phone number on Google for everyone to see or getting business calls through the night with no way to distinguish them from your personal calls. Using a personal number can quickly grow bothersome, hectic, and insecure, especially as your business expands.

If you’re looking for the best second phone number app for your specific situation, this article breaks down the top alternate phone number providers.

The best apps for a second phone number compared

Looking to see how these apps stack up side by side? Here’s a quick snapshot of how each of the best second phone number apps compares.

The best second phone number apps are either built for personal use or for businesses — they rarely work for both types of users. We’ve shortlisted the best options for each use case here.

Where do these apps do well, and where could they perform better? Read on to get all the details about each app below.

1. OpenPhone: The best second phone number app for small businesses

*Nearly all virtual phone numbers share this problem. Since VoIP numbers aren’t tied to a physical address, they can’t be used to call emergency services.

OpenPhone is a modern VoIP phone system built for businesses to help growing teams easily scale their communication. When you sign up, you can get one free US, Canadian, or toll-free number for every user on your team — and you can always get more numbers for $5 each per month. Alternatively, you can assign specific team members to shared phone numbers so anyone available can pick up calls or respond to texts.

OpenPhone is far more than a second phone number app, though. It’s here to help your business streamline your phone and text communication. For example, you can set up automations like an auto-attendant, which lets your clients route their own calls, and texting auto-replies to reach out to contacts over text when you miss incoming calls. Or you can integrate with business apps like Gmail, Slack, Zapier, and HubSpot to speed up your workflow.

Key features of OpenPhone

• Free calls and texts in the US and Canada
• Text from your computer, smartphone, or tablet 
• Affordable international calls
• Shared phone numbers
• Direct team messaging, internal threads, and other collaborative elements
• Call recording
• Voicemail transcriptions
• Auto-attendant (IVR)
• Schedule text messages
• Text message auto-replies
• Business hour settings
• Integrations with business apps like Slack, Zapier, and HubSpot CRM; connect other tools through Zapier and the OpenPhone API

OpenPhone pricing

• Starter: $15 per user per month
• Business: $23 per user per month to access phone menus (IVR), call transfers, analytics, CRM integrations, and more
• Scale: $35 per user per month for AI call tags, dedicated onboarding, and priority chat and email support

How to get a second phone number with OpenPhone

You can obtain a second phone number with OpenPhone in three simple steps:

1. Sign up for an account with OpenPhone — when you sign up, you can try out OpenPhone free for seven days.
2. During signup, select your city or area code in the US or Canada to pick your phone number or select a North American toll-free number.
3. Verify your account with an existing phone number and a credit card.

Then once you’ve signed up, download the iOS, Android, PC, or Mac app to use on any of your devices.

During the signup process, you’ll be asked for a credit card to help keep bad actors off the platform, but you can try calling from your computer for free to confirm it’s a great fit. And when your trial is set to expire, we’ll even email you a heads-up to the email address you used to sign up.

If you run into any issues during the signup process, fill out this form to reach our support team.

2. Google Voice: Best for businesses with Google Workspace

Google Voice for Google Workspace is a popular second phone number app for iPhone, Android, and web users. However, it offers fairly limited features for a business phone system, even with upgrades. Google Voice doesn’t support toll-free numbers, call recording, or many other features modern businesses need.

While Google Voice offers a basic VoIP call forwarding service to all users, you need to upgrade to unlock auto-attendants. Plus, you’re limited to just two integrations, both of which are Google tools (they don’t even include Gmail). You also can’t send text messages if you’re located outside of the US.

Key features of Google Voice

• Unlimited calls to the US or Canada from the US
• Unlimited texts in the US
• Auto-attendant (upgrade required)
• Integrations with Google Calendar and Google Meet

Google Voice pricing

While Google Voice has a free version (in the US only), it’s not intended for business use. You won’t be able to access ring groups, auto-attendants, and other features. For their paid plans:

• Starter: $10 per user per month* (maximum of 10 users)
• Standard: $20 per user per month* to access on-demand call recordings, ring groups, and phone menus
• Premier: $30 per user per month* to access automatic call recordings and advanced reporting

*Plus at least $6 per user per month for Google Workspace.

3. Burner: Best for temporary personal numbers

Burner is a second phone number app for Android and iOS designed to protect your privacy. From spam-blocking technology to do-not-disturb settings, it’s filled with features that can keep you safe. Ideal for those who need an app to call someone from a different number, Burner allows you to maintain your anonymity by easily switching or deleting your alternate phone numbers at any time.

But Burner isn’t the best option for teams looking to make a good impression. While the app lets you purchase up to 200 local phone numbers with area codes throughout the US and Canada, the app doesn’t offer essential business features like shared numbers, call recording, VoIP integrations, and more.

Key features of Burner

• Unlimited calls and texts in the US and Canada
• Text message auto-replies
• Spam call blocking

Burner pricing

Burner charges double its monthly price if you sign up on its mobile app versus the web app. So if you’re interested in checking out a number with Burner, you should sign up on the web to save on your monthly fees. 

• $4.99 per number per month if you sign up on the web
• $9.99 per number per month if you sign up through the mobile app

• Android (4.2 with 60k+ ratings)

4. Hushed: Best for multiple second number subscription plans

Hushed is a unique second phone number app for iPhone and Android that offers multiple subscription options to its users. With Hushed’s pay-as-you-go plan, you can dial numbers outside the US and Canada. Plus,use an eSIM card to use your mobile number outside the country.

Hushed also offers standard second phone number features like custom voicemails, SMS and MMS texting, and call forwarding. You don’t need a SIM card or a traditional phone carrier — their VoIP services work with any internet connection. But like every other personal second phone number app, Hushed lacks the business-friendly features you may need to communicate efficiently.

Key features of Hushed

• Voicemail greeting
• Call forwarding
• Auto-replies
• Call routing

Hushed pricing

Businesses can choose from three plans:

• Prepaid: $2.99 per number unlocks credit-based pricing for calls and texts
• Unlimited: $4.99 per number per month unlocks unlimited calls and texts to US and Canadian numbers
• Pay-as-you-go: $6.99 per number per month unlocks international calls and texts with your Hushed number

• Android (3.7 with 50k+ ratings)

5. Line2: Best for basic business phone features

Line2 is a second phone number app that supports unlimited calls and texts in the US via local and toll-free numbers. It’s also available as a desktop and mobile app.

However, Line2 isn’t a great business phone option. There are no shared numbers, no international calls, and most of the business features you need require plan upgrades or add-ons. It does the job for one-person businesses but no longer works when you add another person to your team. 

Key features of Line2

• Unlimited calls in the US and Canada
• Unlimited texts in the US
• Auto-attendant (upgrade required)
• Call recording (add-on or upgrade required)
• Voicemail transcriptions (add-on or upgrade required)

Line2 pricing

Line2 offers two pricing options depending on the frequency you prefer to pay your bills:

• Monthly: $15.99 per month billed monthly 
• Annual: $13.75 per month billed annually

6. Dialpad: Best for large contact centers

Dialpad is a business phone system that offers a number of helpful features, including call routing, call recording, and voicemail transcriptions. It’s best suited for teams with large contact centers due to its AI-powered coaching features like AI scorecards and real-time AI assists. 

Unfortunately, Dialpad is an expensive second phone option for businesses. It requires you to upgrade for international texting, auto-replies, and integrations, which can make it an incredibly costly service for small businesses. Plus, you must pay for at least three users for a Pro plan or 100 users for an Enterprise plan if you do upgrade.

Another issue? Several teams find Dialpad to be overengineered and clunky compared to other business phone platforms like OpenPhone.

Key features of Dialpad

• Unlimited calls and texts in the US and Canada
• Call recording
• Voicemail transcriptions
• Auto-attendant (IVR)
• Integrations with business apps like Slack, Zapier, and HubSpot (upgrade required)

Dialpad pricing

Dialpad’s pricing for their business phone solution includes three different tiers:

• Standard: $15 per user per month (maximum of 3 users on a shared number; no additional numbers allowed)
• Pro: $25 per user per month (minimum of 3 users) to get additional numbers, international texting, call transfers, and auto-replies
• Enterprise: Custom pricing (100-user minimum) to access dial by extension, priority support, and 100% uptime

• Android (4.2 with 1,900+ ratings)

7. Ooma: Best for reaching Mexico and Puerto Rico

Ooma is a second phone number app that’s built for small businesses. When you sign up, you can get one free toll-free number for your team or choose from a variety of local numbers. It also uniquely supports intercom calling and analog fax machine support (which you may never use unless you own a physical office).

The downside is that Ooma is pretty costly for the value it provides. For example, you can’t access texting, call recording, or voicemail transcriptions on the basic plan (only on higher tiers). You also need to upgrade to access Ooma’s desktop app. Otherwise, you have to work exclusively on your phone.

Key features of Ooma

• Unlimited calls to US, Canada, and Mexico
• Auto-attendant
• Call recording (upgrade required)
• Voicemail transcriptions (upgrade required)

Ooma pricing

Ooma offers three plans to choose from:

• Office Essentials: $19.95 per user per month
• Office Pro: $24.95 per user per month to access Ooma’s desktop app, phone menus, call recording, voicemail transcriptions, Google and Office 365 integrations, and video meetings
• Office Pro Plus: $29.95 per user per month to access reporting, Salesforce and Microsoft Dynamics 365 integrations, and automatic call distribution

• Android (4.5 with 1,200+ ratings)

8. Grasshopper: Best for phone number extensions

Grasshopper is another VoIP platform marketed toward small businesses. It differs from other second phone number apps by offering all its features — including voicemail transcriptions and custom voicemail greetings — in every plan. This means you only pay for the phone numbers and extensions you need.

Since the basic plan only includes one phone number (and five with its highest-tier option), Grasshopper isn’t the best VoIP service for growing teams. It also lags behind other business phone options in terms of the features it offers. For example, it doesn’t offer integrations, shared phone numbers, or call recording. While it offers local and toll-free numbers, you can only send MMS and group messages from local US numbers — and you can’t send SMS messages internationally or from a toll-free number to a Canadian number. And if you want to make international calls, you have to put down a $500 deposit first, which is another obstacle if you want to sell globally.

Key features of Grasshopper

• Unlimited calls in the US and Canada
• Call forwarding
• Voicemail transcriptions
• Custom voicemail greetings

Grasshopper pricing

Grasshopper offers three plans — True Solo, Solo Plus, and Small Business. While each plan offers all its features, they differ by the number of users and extensions you can access. 

Here’s how much each plan costs:

• True Solo: $14 per month for one user, one phone number, and one extension
• Solo Plus: $25 per month for unlimited users, one phone number, and three extensions
• Small Business: $55 per month for unlimited users, four phone numbers, and unlimited extensions.

9. TextNow: Best for plans with high-speed data

TextNow is a Canadian second phone number app offering unlimited free calling and texting in the US and Canada. Since it works on a PC, iPhone, Android, and iPad, you can switch between devices while working on the go. You can also pay $4.99 for a TextNow SIM card to unlock high-speed data (starting at $39.99 per month for 10 GB high-speed data, then unlimited 2G speeds).

While TextNow may be free, it’s not built for small business owners. Basic features like voicemail transcriptions and call forwarding require upgrades. Plus, customer reviews complain of an overwhelming number of in-app ads. If you want to make phone calls without ads, you need to pay for an upgrade.

Key features of TextNow

• Free phone number (fees apply to premium numbers; you must unlock your iPhone or Android to use the mobile app)
• Voicemail transcription (requires upgrade)
• Incoming caller ID (requires upgrade)
• International calling and texting (requires the purchase of credits)

TextNow pricing

TextNow is free to use with ads. To make calls without WiFi, you first need to purchase a SIM card ($4.99). Then, you have the option to purchase three data bundles:

• Hour Pass: $0.99 for 60 minutes of unlimited talk, text, and data
• Day Pass: $4.99 for 24 hours of unlimited talk, text, and data
• Month Pass: $39.99 for one full month of unlimited talk, text, and data

Additional plan options from TextNow include locking in your number and removing ads from their app:

• Lock in Number: $1.99 per week
• Ad Free+: $6.99 per week
