Analyzing the best virtual business phone number apps

Here’s a detailed exploration of how these eight virtual phone services stack up, ranked from highest to lowest based on their price, functionality, and integrations.

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


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


  • Can’t verify accounts through two-factor authentication*
Business phone number apps: OpenPhone's desktop and mobile apps

*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 of 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.

With OpenPhone’s comprehensive features, you’ll never miss a vital customer detail or request again. Every plan includes the essentials like call recording, voicemail transcripts, and more.

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 representative. Any of your customer service representatives can read notes from previous calls and get up to speed.

OpenPhone is also the solution for improving operational efficiencies. Use generative AI to provide real-time call transcriptions, summaries, and message responses, expediting your team’s next steps and action items. We also integrate with popular business software solutions like Slack, Salesforce, HubSpot, and Zapier.

OpenPhone is the best business phone number app for small businesses and growing teams, but you don’t have to take our word for it. Try OpenPhone with our 7-day free trial.

    2. Google Voice: Best for Google Workspace users


    • Make free calls to the US
    • Integrates with other Google Workspace apps
    • Share responsibility for incoming calls (requires upgrade)


    • Texting is available in the US only
    • Costs more than other business phone system providers
    • No toll-free numbers
    • No desktop app is available
    • No auto-replies
    • No integrations outside Google Workspace
    Business phone number apps: Google Voice interface

    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.

    The most significant advantage of Google Voice is that it 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, that Google Voice does not provide a free business phone number. A line is free for personal phones (i.e., the Google Voice plan), but it costs $10 a month per user minimum for businesses through Google Voice for Google Workspace — plus an additional $6 per user per month, as you must have an active Google Workspace account.

    That’s not all: Google Voice 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
    • Voicemail transcriptions
    • Google Calendar and Google Meet integrations
    • Upgrade required for advanced features like auto-attendant

    Google Voice pricing

    Google Voice pricing

    Google Voice has three pricing plans:

    • Starter: $10 per user per month*
    • 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

    *Plus an additional $6 per user per month payment for Google Workspace required to use Google Voice for business.

    Google Voice user ratings 

    • iOS: 4.3 with 59,000+ ratings
    • Android: 4.4 with 348,000+ ratings
    • G2: 4.1 with 150+ reviews

    3. Grasshopper: Best for multi-digit extensions


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


    • No call recording
    • No shared phone numbers
    • No Slack, Zapier, or CRM integrations
    Business phone number apps: Grasshopper app interface

    As a legacy VoIP provider, Grasshopper is one of the oldest and most well-known virtual business phone number apps. One of its standout features is its 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 of plan. You only pay more for additional user seats, numbers, and extensions 

    Compared to other providers mentioned in this article, their platform is relatively bare, with basic features like voicemail greetings and transcriptions. Even when they go the extra mile and offer features like auto-replies, there are enough limitations in place that you won’t get the full value out of them. Auto-replies in Grasshopper only go out to first-time callers — not every time someone contacts you over calls or texts.

    Also, keep in mind that limitations in phone numbers (a max of 5 on the highest plan without paying extra) and zero integrations can be a problem as your business grows. Sharing responsibility for incoming calls also costs extra ($10 per month) on their dated platform.

    Key features of Grasshopper

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

    Grasshopper pricing

    Business phone number apps: 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

    Grasshopper user ratings

    • iOS: 4.8 with 43,000+ ratings
    • Android: 4.2 with 3,900+ ratings 
    • G2: 4.0 with 140+ reviews

    4. Nextiva: Best for large enterprise teams


    • Unlimited calling within the US and Canada
    • Video calling features available


    • SMS and MMS are offered only on higher pricing tiers with a capped message limit
    • Call recording is only available with Enterprise plan
    • Limited toll-free minutes on each plan 
    Business phone number apps: Nextiva

    Video conferencing and screen sharing are what Nextiva does best. Built for teamwork-based industries like eCommerce and IT, this provider’s unified communication platform supports 10-digit and toll-free numbers. Integrations with Salesforce, Zendesk, and CRM platforms are provided on their second and third-highest plans.

    But without business texting services on the Essential plan and message limits even when they upgrade, many teams seek out Nextiva alternatives. Also missing from Nextiva’s base plans are essential features like call recording and voicemail transcription. If you want to provide a toll-free option to your customers, Nextiva limits your toll-free minutes, which means you might have to pay for toll-free calls every month on top of your monthly fee.

    Key features of Nextiva

    • Virtual fax services
    • Integration with Google Contacts
    • Unlimited voice or video conference calling
    • Voicemail transcriptions (requires upgrade)
    • WiFi call management

    Nextiva pricing

    Business phone number apps: Nextiva pricing

    Nextiva offers three plans to its customers:

    • Essential: $18.95 per user per month for unlimited calling within the US and Canada, video conference recording, auto attendant, and contact integrations
    • Professional: $22.95 per user per month to access SMS/MMS messaging, voicemail transcriptions, and HubSpot and Zendesk integrations
    • Enterprise: $32.95 per user per month to access call recording and Salesforce and ServiceNow integrations

    Nextiva user ratings

    • iOS: 3.8 with 4,200+ ratings
    • Android: 3.8 with 3,000+ ratings
    • G2: 4.5 with 3,100+ reviews

    5. Ooma: Best for teams that need fax and paging support


    • Unlimited calling in the US, Canada, Mexico, and Puerto Rico
    • Auto-attendant
    • Ring groups


    • Texting is only available on higher tiers
    • Voicemail transcriptions are only available on higher tiers
    • Call recording is only available on higher tiers
    • Unnecessary features like intercom calling and analog fax machine support
    Business phone number apps: Ooma interface

    The VoIP mobile app from Ooma was specifically designed for small businesses. Users can access free inbound and outbound calling in North America and Mexico. Better yet, extension dialing and call forwarding are available to all in-app users.

    However, Ooma may be restrictive for business growth once your brand gets to a certain size. A lack of analytics may prevent you from measuring activity on a second phone number. Plus, Ooma offers legacy phone features like virtual fax and analog paging support, which means you’d pay for features you don’t need. You’ll also need to upgrade to access their desktop app if you want to call and text from your computer using Ooma. Any text messaging requires you to pay for one of their higher-tier plans. If you also need voicemail transcriptions or call recording software, get ready to upgrade.

    Key features of Ooma

    • Smartphone mobile apps
    • Virtual receptionists
    • Multi-ring and ring groups
    • Overhead paging
    • Text messaging (requires upgrade)
    • Virtual and analog fax machine support

    Ooma pricing

    Ooma pricing

    Ooma has three pricing plans for small businesses:

    • Essentials: $19.95 per user per month
    • Pro: $24.95 per user per month to unlock texting, voicemail transcriptions, call recording, and Ooma’s desktop app
    • Pro Plus: $29.95 per user per month for Ooma’s Salesforce integration, hot desking, and Microsoft Dynamics 365 integration

    Ooma user ratings

    • iOS: 4.9 with 7,000+ ratings 
    • Android: 4.4 with 1,200+ ratings 
    • G2: 4.6 with 100+ reviews

    6. eVoice: Best for teams with limited phone needs


    • Available on iOS and Android
    • Inbound online faxing available


    • Limited numbers are available for each account
    • SMS/MMS messaging costs extra
    • Confusing feature add-on options
    • Call recordings are only stored for 30 days
    • Apps are updated infrequently
    Business phone number apps: eVoice interface

    eVoice provides virtual phone and live receptionist services to small businesses of all kinds. The eVoice app is currently compatible with iOS and Android. 

    eVoice is affordably priced, but it comes with several drawbacks you should consider. It doesn’t appear to have shared numbers or integrations, which means your team will lose business context quickly and might struggle to stay on the same page. 

    Key features like business texting, call recording, and voicemail transcriptions are only available as add-on features, and it’s unclear from their website how much these additional features cost. 

    Bottom line: eVoice is fine for solo businesses, but it’s inefficient as you add more people to your team.

    Key features of eVoice

    • Call forwarding after hours
    • Inbound caller ID screening
    • Unlimited calls
    • Call queuing
    • Sequential ringing

    eVoice pricing

    Business phone number apps: eVoice pricing

    eVoice offers a single plan to businesses for $12 per month to access all its features. 

    What’s missing from this pricing is eVoice’s numerous add-ons, including call recording, voicemail transcription, business texting, and more. 

    eVoice user ratings

    • iOS: 3.7 with 490+ ratings
    • Android: 3.7 with 1,600+ ratings

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


    • SMS and MMS messaging
    • Auto-replies available


    • No shared numbers
    • No call recording
    • Auto-attendant available only on the Enterprise plan
    • International calling available only on the Enterprise plan
    • No Slack, Zapier, or CRM integrations
    Business phone number apps: Sideline app

    Sideline provides lean functionality with its business phone services. Both desktop and mobile apps allow users to access call logs across devices. SMS texting capabilities are perhaps its most notable business solution. You can’t get all its features on a single plan, though — and you’ll have to compromise to get what you want.

    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
    • Call announcement software
    • WiFi calling
    • Auto-replies
    • Mobile app downloads
    • Free and unlimited calls (US only)

    Sideline pricing

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

    • Standard: $10.84 per month, billed annually to access free calling and texting to the US, auto-replies, voicemail to text, group messaging, and number porting
    • Enterprise: $14.49 per business line per month to access international calling and auto-attendant features

    Sideline user ratings

    • iOS: 4.3 with 1,200+ ratings
    • Android: 3.9 with 6,200+ ratings

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


    • Manage text and email conversations
    • Manage conversations from Facebook, Messenger, and Instagram


    • No international calling
    • No call recording, call summaries, or call transcriptions
    • Only one business number available
    • No Slack, Zapier, or CRM integrations
    • No auto-attendant features
    Business phone number apps: GoDaddy Conversations app

    GoDaddy Conversations is a virtual phone number app that lets you communicate with your customers through channels like Facebook, Instagram, chat, or your web contact form — from one unified system. Conversations replaces Smartline, GoDaddy’s previous business phone number app. 

    While GoDaddy Conversations makes messaging across social media platforms easier, the solution lacks many essential features customer support teams need to thrive. For example, it doesn’t offer shared numbers, call recording, an auto-attendant, group calling, or international calling.

    It also only provides users with one business phone number, limiting fast-growing teams that need multiple numbers for different departments or locations.

    Key features of GoDaddy Conversations

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

    GoDaddy Conversations pricing

    Conversations offers the same features in each of its plans. The difference is you can choose to get a local or a toll-free number (toll-free numbers don’t charge customers when they call or message your team). 

    Business phone number apps: GoDaddy Conversations pricing
    • Local Number: $12.99 per month
    • Toll-free Number: $16.99 per month

    GoDaddy Conversations user ratings

    • iOS: 4.4 with 1,800+ ratings 
    • Android: 3.8 with 600+ ratings

    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 out of their daily responsibilities.
    • Low 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.

    5 signs you need to get a business phone number app

    We’ve covered the top eight apps, but how do you know when you actually need a business phone number app? Here are five signs your team is ready to get one:

    1. Your team is growing fast: You can get by without a business phone solution when you’re a one-person team. However, if you’re adding team members and want to share responsibility for customer calls, you’ll need to get a shared number from a business phone app. 
    2. You’re getting calls outside work hours: Want a better work-life balance for you and your team? Business hours helps you send an auto-reply or voicemail to customers who try to reach you when you’re offline. You can also forward calls to a secondary number if you need to.
    3. You’re using multiple apps to manage work communications: Using a business phone, call recording app, and Slack to update your team? Business phone number apps let you keep your tech stack lean so you don’t have to constantly switch contexts. 
    4. You want to take repetitive tasks off your team’s plate: Your team shouldn’t get bogged down in work that doesn’t move the needle. With business phone features like auto-replies, snippets, and CRM and Zapier integrations, you can save your team hours.
    5. You need to quickly add new local numbers: If you want to acquire customers in new cities, you need a local number to earn their trust. A business phone number app helps you create new local numbers so you can expand quickly.

    If you also want auto-replies, integrations, and other features that take more work off your plate, you’ll have to subscribe to a paid app.

    How much do business phone number apps cost?

    A starting plan for business phone systems costs as low as $15 to $25 per user per month. Mid-range VoIP phone systems cost between $25 to $50 per user per month.
