7 Best Free Business Phone Number Apps for Small Businesses in 2026

Fit Small Business is the go-to source for the best answers in technology advice, with accurate and objective reviews of products and services for small businesses. For this update, I checked each provider's current pricing page, plan terms, and feature documentation, then scored every app against the same six-part weighted rubric. For a full breakdown, review my methodology below.

I evaluated each app using a weighted scoring rubric with standardized rating criteria. My research included reviewing provider pricing pages, plan details, help center resources, and product documentation to verify costs and capabilities. To identify the best options for small businesses, I assessed each provider across the following criteria:

Quo, formerly OpenPhone, is my top pick for small teams that want a well-rounded business phone system with strong collaboration and AI features. Every plan includes unlimited US and Canada calling and texting, shared business numbers, voicemail transcripts, and Sona, its AI agent. Shared numbers are especially useful for teams that want multiple employees to handle calls and texts from the same business line.

The biggest drawback is that Quo doesn't have a permanent free plan, and its seven-day trial is relatively short. You'll also pay a one-time carrier registration fee plus monthly messaging maintenance fees, while features such as phone menus, CRM integrations, and live chat support require the Business plan or higher.

Extra numbers cost $5 per month. Texting registration costs $19.50 one-time, plus $1.50 to $3 per month in messaging maintenance. International calls and texts cost extra. Quo offers a seven-day free trial on every plan.

• Sona AI agent: Sona answers calls for your business on every plan, drawing from 1,000 free automation credits each month.
• Shared numbers: Several teammates can call and text customers from one business line.
• AI assistant connections: Quo's MCP integration lets you bring call and text data into ChatGPT or Claude.
• API access on every plan: You can build custom workflows with the Quo API, even on Starter.

Dialpad is the app I'd pick if you want AI built directly into your calling workflow. Its real-time transcription and AI Recaps automatically capture conversations, action items, and next steps, reducing the need to take notes manually. It also combines business calling, messaging, and meetings in one app and integrates with popular CRM and productivity platforms.

The main drawback is pricing if you don't want an annual commitment. Standard costs $27 per user with monthly billing versus $15 when billed annually, and there is no free plan once the 14-day trial ends. Teams primarily looking for basic calling rather than AI capabilities may therefore find less expensive options.

Dialpad includes its AI features across pricing tiers and offers a 14-day free trial.

• AI Recaps: Dialpad writes post-call and post-meeting summaries with action items and next steps.
• Real-time transcription: You can read a live transcript during the call and search it afterward.
• One app for calls, messages, and meetings: Your team can switch from a call to a video meeting without changing tools.
• Broad integrations: Dialpad connects with Salesforce, HubSpot, Zendesk, Zoho, Clio, Google Workspace, and Microsoft 365.

Grasshopper is a strong choice for growing small businesses that want to avoid per-user pricing. Solo Plus and Small Business support unlimited users for one flat monthly rate, while local, toll-free, and vanity numbers give businesses flexibility in how they present themselves to customers. It also covers essentials such as unlimited calling, business texting, call forwarding, voicemail transcription, and desktop and mobile apps. For setup tips, see our guide on how to use the Grasshopper phone system.

However, some useful extras can quickly increase the cost. Additional numbers and call blasting (ringing several phones at once) each cost $9 per month, while Voice Studio greetings cost $75 per order. Business texting also requires carrier registration, which can take 10 to 30 business days, so businesses relying heavily on SMS should factor that setup time into their decision.

Prices cover your whole account, with unlimited users on Solo Plus and Small Business. Add-ons: extra numbers ($9/month each), extra extensions ($3/month each), call blasting ($9/month), and Voice Studio ($75 per order). Grasshopper offers a seven-day free trial with no credit card required.

• Unlimited users: You can add team members as your business grows without per-user fees.
• Instant Response: Grasshopper sends automated text replies to callers you miss, even after hours.
• Virtual fax: You can handle faxes through your Grasshopper account without a fax machine.
• Voice Studio: Professional voice actors record your greetings in English, Spanish, or French.

CallHippo is my pick for businesses that need local phone numbers outside the US. It offers numbers in more than 100 countries, making it useful for companies establishing a local presence in multiple markets. Its Basic plan is free for the first six months, while paid plans add capabilities such as an omnichannel inbox, integrations, multilingual IVR, and expanded international calling features.

The free access is temporary, however, and Basic users must move to a paid plan after six months. Starter also limits US and Canada calling to 1,000 minutes, while features such as call recording require Professional or higher. There are additional costs to consider as well, including business texting setup fees, taxes, and optional features such as branded calling.

Paid plans come with a 10-day free trial, no credit card required. CallHippo advertises local numbers from $1 per month, and local taxes apply on top of listed prices.

• Numbers in 100+ countries: You can add local numbers in markets such as Australia, Canada, Brazil, Germany, and Singapore.
• Smart failover: Basic and paid plans include failover settings that keep calls moving when your first route is unavailable.
• Multilingual IVR: Professional and Ultimate customers can greet callers with phone menus in more than one language.
• Omnichannel inbox: Starter and higher plans collect calls and texts in one view.

MightyCall is best suited to small teams handling relatively high call volumes. Its no-code call flow designer, multilevel IVR, call queues, and ring groups provide more sophisticated call routing than a basic virtual phone service, while every plan includes three business numbers. Growing teams can also move to Pro for supervisor tools, live call monitoring, AI summaries, and analytics.

It's less attractive for solo users or very small teams because Core, Pro, and Power require at least three users, putting Core's minimum annual billing cost at $60 per month. Its free trial is also restrictive, ending after seven days or 100 US and Canada minutes, so you'll need to prioritize which workflows you test. If MightyCall feels like more than you need, browse our list of MightyCall alternatives.

The free trial lasts seven days and includes 100 domestic minutes, five SMS, and five MMS. Unlimited calling and messaging fall under MightyCall's fair use policy.

• Call flow designer: You can build routing rules by dragging steps into place, with no coding.
• Call queues and ACD: Callers wait in line and reach the next available agent automatically.
• Supervisor tools: Pro and higher plans add a supervisor workspace and live call monitoring, and MightyCall supports listen, whisper, and barge modes.
• E911 and HIPAA support: Emergency calling and HIPAA compliance help healthcare and field teams.

Zoho Voice is my pick for existing Zoho users who want to start with an ongoing free plan. Solo supports one user and includes 250 free outgoing minutes per month, call recording, voicemail, contacts, and call logs, while native connections with Zoho CRM, Bigin, Desk, and Recruit make it particularly useful for businesses already working in the Zoho ecosystem.

The free plan isn't completely cost-free because you'll still need prepaid credits to rent a phone number and cover usage beyond the included minutes. Solo also lacks features such as IVR, call queues, and SMS, which start with Team, and Zoho doesn't publish the dollar value of its credits on its pricing page. Businesses that don't already use Zoho may therefore find Quo or Grasshopper easier to set up and budget for.

Number rental costs 1 credit per month for a local number, 2 for toll-free, and 5 for mobile. US texts cost 0.009 credits to send and 0.007 credits to receive. Zoho offers a 15-day free trial that gives you a taste of the paid tiers with no credit card required, but you can't buy a number until the trial ends.

• Free Solo plan: A single user can run business calls on Zoho Voice with no monthly subscription fee.
• Native Zoho integrations: Calls and call logs connect directly with Zoho CRM, Bigin, Desk, and Recruit.
• AI call analysis: Zoho Voice can transcribe recorded calls and generate summaries and sentiment analysis.
• Numbers in many countries: You can buy local and toll-free numbers in any country where your business operates, subject to availability.

Talkroute is a good fit for startups that need a straightforward phone system for a small team without high per-user costs. Its plans bundle multiple users as you move up the tiers, while call stacking lets businesses handle several simultaneous calls even when operating from a single phone. It also provides cross-platform apps, business caller ID, and professionally recorded greetings through Voice Studio.

Its biggest limitation is integration depth. Talkroute relies on Zapier and its API instead of offering the native CRM integrations available from providers such as Quo, Dialpad, and MightyCall. Important features are also tier-gated: phone menus start with Plus, while call recording and reporting require Pro, making the entry-level plan better suited to businesses with relatively simple calling needs.

Additional users cost $5 per month. Add-ons include an AI receptionist (from $39 per month, or $0.40 per AI minute pay as you go) and bulk texting (from $55 per month). Talkroute offers a seven-day free trial with no contract.

• Call stacking: You can take several calls at once on one phone, with music on hold for waiting callers.
• Voice Studio: Talkroute's in-house voice talent records your business greetings.
• Outbound caller ID: Your business number and name (CNAM) appear when you call customers.
• Cross-platform apps: Talkroute runs on macOS, Windows, Linux, iOS, Android, and any browser.
