Next, here’s a detailed breakdown of how these 10 virtual phone services stack up, ranked from highest to lowest based on their price, functionality, and integrations.

1. OpenPhone: The best business phone number app for growing teams

Pros

• Unlimited calls and texts to the US and Canada
• Local and toll-free virtual numbers are available
• Available on iOS, Android, desktop, and the web
• Internal threads, contact notes, and call recordings for team coordination
• Auto-attendant functions (IVR) for inbound calls

Cons

• Can’t verify accounts through two-factor authentication*

*Nearly all virtual phone numbers share this problem. For safety reasons, companies like Facebook, Uber, and Google rarely let you authenticate accounts through a virtual phone number.

OpenPhone is an all-in-one VoIP system that scales with your business. Since OpenPhone operates over an internet connection, you can manage all your business communications (calls and texts) on any existing computer, smartphone, or tablet — there’s no need to invest in a desk phone or expensive hardware. Plus, every plan includes the essentials like call recording and voicemail transcripts.

One of the biggest draws of OpenPhone is how easily it enables team collaboration. Users can access shared numbers, simultaneous ring, contact notes, and internal threads. With these features, your customers won’t wait long on hold or have to repeat themselves when they reach a new rep. Any of your customer service representatives can read notes from previous calls and get up to speed.

You can also expedite your team’s next steps and action items by using OpenPhone’s AI transcriptions and summaries and message responses. We also let you connect your favorite tools like Slack, Salesforce, HubSpot, and Zapier with our integrations.

Pros

Cons

• Costs more than other business phone system providers
• No integrations outside Google Workspace

If you’ve ever Googled ‘VoIP,’ you’ve no doubt run into Google Voice. This is one of the most popular business solutions on the market.

Google Voice integrates with Google Workspace apps, making it a popular draw for businesses that already use Gmail, Google Sheets, and Google Docs.

Keep in mind, though, it doesn’t offer toll-free numbers, auto-replies, or differentiation between personal phone calls and your second number.

Key features of Google Voice

• Free unlimited calling to the US from anywhere (and to Canada from the US)
• SMS in the US
• Mobile phone and web apps
• Google Calendar and Google Meet integrations
• Auto-attendant (requires upgrade)

Google Voice pricing

Google Voice’s pricing plans give you three options to choose from:

• Standard: $20 per user per month to unlock on-demand call recordings, ring groups, and phone menus
• Premier: $30 per user per month to unlock automatic call recordings and advanced reporting

An additional $7 per user per month for Google Workspace is required to use Google Voice for business.

3. Grasshopper: Best for multi-digit extensions

Pros

• Unlimited calling to the US and Canada
• Auto-attendant (phone menu) with extensions

Cons

• $500 deposit to make international calls
• No shared phone numbers
• No Slack, Zapier, or CRM integrations

As a legacy VoIP provider, Grasshopper is one of the oldest virtual business phone number apps. One of its standout features is single-digit extensions for departments and multi-digit extensions for employees. Another notable feature is its pricing — Grasshopper users get access to all its features on each plan. You only pay more for additional user seats, numbers, and extensions.

Compared to other providers in this article, their platform is relatively bare-bones with basic features like voicemail greetings and transcriptions. Even when they go the extra mile and offer auto-replies, they can only go out to first-time callers.

Key features of Grasshopper

• Unlimited calls to Canada and the 48 continental states
• Android and iOS mobile apps
• Vanity numbers
• Call transfers (requires upgrade)
• Voicemail to text

Grasshopper pricing

Grasshopper’s pricing offers three plans. While each plan provides all its features, they differ by the number of users and extensions you can access. 

Here’s what you can expect to get with each:

• 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

4. Nextiva: Best for large enterprise teams

Pros

• Unlimited calling within the US, Puerto Rico, and Canada (requires upgrade)
• Video calling features are available (requires upgrade)

Cons

• SMS and MMS require an upgrade
• Call recording requires an upgrade
• Voicemail transcriptions requires an upgrade

Nextiva launched in 2006 as a basic business phone number app. Today, it brands itself as a customer experience company, which is clear given that its base plan lacks essential phone features.

For example, if you want to make calls and send texts, you’ll need to upgrade to the Core plan, which costs $30 per user per month. Plus, reps can only send 100 texts each per month unless you upgrade. Unsurprisingly, many small businesses seek out Nextiva alternatives. 

Key features of Nextiva

• Virtual fax services (requires upgrade)
• Integration with Google Contacts (requires upgrade)
• Unlimited voice or video conference calling (requires upgrade)
• Voicemail transcriptions (requires upgrade)
• Toll-free number support (requires upgrade)

• Engage: $40 per user per month for customer-to-team SMS messaging, toll-free number and minutes, advanced reporting, and MS Teams integration

5. Sideline: Best if you only need one additional number

Pros

• SMS and MMS messaging
• Auto-replies are available

Cons

• No shared numbers
• No call recording
• Auto-attendant is available only on the Enterprise plan

Sideline provides lean functionality with its business phone services. Its SMS and MMS support are perhaps their most notable business feature. However, you can’t get all its features on a single plan, and you have to upgrade to access international calling and an auto-attendant.

Keep in mind that while Sideline is a second number app, it isn’t a VoIP service. This platform requires you to have a pre-existing phone service to take and place calls. You’ll need to pay for their services as well as a traditional phone carrier. 

Key features of Sideline

• Group messaging
• WiFi calling
• Auto-replies
• Mobile app 
• Free and unlimited calls (US only)

Sideline pricing

Sideline’s pricing details are buried in their support center. Here’s how much each plan costs:

• Enterprise: $14.49 per business number per month to access international calling and auto-attendant paid add-ons

6. GoDaddy Conversations: Best for managing Facebook Messenger and Instagram chats

Pros

• Set up custom voicemail greetings
• Manage conversations from Facebook, Messenger, and Instagram in one inbox

Cons

• No international calling
• No call recording, call summaries, or call transcriptions
• No auto-attendant features

GoDaddy Conversations replaces SmartLine, GoDaddy’s previous business phone number app. The platform lets you communicate with your customers through channels like Facebook and Instagram from one central inbox.

However, it lacks business features, like shared numbers, call recording, auto-attendant, and group calling, that customer-facing support teams need to deliver a great experience.

Key features of GoDaddy Conversations

• Unified inbox
• Set business hours
• SMS and MMS messaging
• Custom voicemail options
• Number blocking

GoDaddy Conversations pricing

7. RingCentral: Best for desk phones

Pros

• Desk phone support
• Multi-level auto-attendant

Cons

• Voicemail transcriptions requires an upgrade
• Base plan only includes 25 texts per user per month
• Limited toll-free minutes

RingCentral is a legacy business communications platform that was founded in 1999. It supports desk phones, which is handy if your business still uses them.

But RingCentral isn’t without its drawbacks. For example, you’ll need to pay a one-time setup fee of $30 for vanity phone numbers. Plus, you only get more than 100 pooled toll-free minutes per month if you upgrade. Text messaging is also capped at 25 messages per user per month, which might not be enough for your business.

Key features of RingCentral

• IVR
• SMS and MMS support
• Shared voicemail
• Internet fax (requires upgrade)
• Unlimited calls in the US and Canada

RingCentral pricing

RingCentral’s pricing plans give you three different options to choose from:

• No third-party integrations

1-VoIP is a provider that launched in 2005 and offers residential and business VoIP services. Plus, it offers a SIP Trunking service that lets you make unlimited simultaneous calls, which is handy if you handle a high volume of calls.

While 1-VoIP provides all its features on every plan, you don’t get many to choose from. For example, it doesn’t offer auto-replies or scheduled texts. This means if your team needs to speed up their workflow to reduce response times, you’ll have to look for another phone number app.

Key features of 1-VoIP

• Extension transfer
• Call recording
• Auto attendant
• Business hours
• Call parking

1-VoIP pricing

Let’s break down 1-VoIP’s pricing for its business plans:

9. 800.com: Best for promotional campaigns 

Pros

• Auto-replies

Plus, 800.com lets you create and execute promotional campaigns. You can use it to send bulk messages from a virtual SMS number, perfect for letting customers know about service updates, special promotions, or upcoming sales.

But 800.com’s plans have some notable drawbacks. If you need unlimited minutes, you have to pay $49 per month. But even at this price point, the plan only lets you have three users. 

And while 800.com lets you buy additional phone numbers, they cost $9 per month, which is nearly double OpenPhone’s price. 

Key features of 800.com

• API and webhook access
• Texting
• Call screening
• Extensions
• Call recording

800.com pricing

800.com’s pricing offers you three different plans to pick from:

• Third-party integrations are only available on the highest-tier plan

Vonix is a VoIP and business messaging platform that has been around since 2008. It lets you handle all your business texts, picture messages, web chats, and social media messages in one central box.

While Vonix has good features, there are some downsides to keep in mind. For example, you can’t store call recordings on the basic plan at all. Plus, you’ll need to upgrade to the Team plan to access analytics, which prevents your team from making data-driven decisions unless you pay $39.99 per user per month.

Key features of Vonix

• Music on hold
• Advanced call routing
• Texting auto responders
• Call parking

Vonix pricing

How we ranked the best business phone number apps

We determined the top options after reviewing the following key factors across each app:

• Reliability: Call drops and system outages are dealbreakers.
• Bang for your buck: What value does the app generate for your business? The cheapest option is usually not the best app. You need a system that saves your team time and has predictable monthly costs.
• Third-party integrations: Speaking of saving time, integrations can help your team cut repetitive tasks from their daily responsibilities.
• Shallow learning curves: Customizing your phone settings and getting team members up and running shouldn’t take hours. The best business number apps have intuitive interfaces that aren’t taxing to operate if you’ve ever used a smartphone.
• Customer service: If questions come up and you don’t see your question addressed in the Help Center, you need a support team that’s responsive.
