Cheap VoIP does not have to mean bad VoIP. The lowest-priced business phone plans still give you a real business number, mobile and desktop apps, voicemail and call routing – what you trade away at the bottom of the market is advanced integrations, contact-centre tools and AI, not core call quality. We compared the most affordable business VoIP services on real entry price, what the cheapest tier actually includes, and where the hidden costs hide. Here are the cheapest VoIP services worth using in 2026.
TL;DR – the cheapest picks:
- Cheapest for solo operators: Grasshopper – flat pricing from ~$14/mo for unlimited users. (review)
- Cheapest per user with unlimited calling: Ooma – under $20/user, unlimited North America calling, no contract. (review)
- Best value for the money: OpenPhone – texting and a modern app included from ~$19/user. (review)
- Cheapest all-in-one voice + video: GoTo Connect – the most affordable genuine all-in-one. (review)
Who has the cheapest VoIP? For a single line, Grasshopper is cheapest at about $14/month flat (not per user). The cheapest per user is Google Voice at $10/user/mo if you already pay for Google Workspace, or Zoom Phone’s metered plan from $10/user/mo. For unlimited calling without Workspace, Ooma is under $20/user, and Quo (formerly OpenPhone) is the best value at $19/user with texting included.

1. Grasshopper – Cheapest for solo operators
Grasshopper uses flat pricing instead of per-user fees, so a whole small team shares one plan from about $14/month. It is a virtual number service that rings through to your own phone rather than a full system – which is exactly why it is so cheap. You get a professional business number, business texting, a virtual receptionist and call forwarding without paying per seat.
Grasshopper pricing (2026)
- True Solo: ~$14/mo – one number, three extensions.
- Solo Plus: ~$25/mo; Partner: ~$46/mo; Small Business: ~$89/mo.
- Flat and unlimited-user on every tier; see pricing.
Who Grasshopper is best for: solopreneurs and very small teams that want the cheapest possible professional business line on the phone they already own.

2. Ooma – Cheapest per-user with unlimited calling
Ooma Office is the cheapest way to give a small office real per-user calling with no contract. The entry Essentials plan includes unlimited calling across the US, Canada, Mexico and Puerto Rico plus a virtual receptionist – hard to beat on price for straightforward calling.
Ooma pricing (2026)
- Essentials: ~$19.95/user/mo – unlimited NA calling + virtual receptionist (no texting or video).
- Pro: ~$24.95 adds desktop app, recording, SMS and video.
- No annual contract; 30-day return. See pricing.
Who Ooma is best for: small offices that want the lowest-cost unlimited calling and do not need texting or video on day one.
3. OpenPhone – Best value for the money
OpenPhone (now Quo) is not the absolute cheapest, but it is the best value: from about $19/user you get business texting, shared numbers, a genuinely modern app and AI call summaries – more capability per dollar than most budget systems that charge extra for texting.
OpenPhone pricing (2026)
- Starter: ~$19/user/mo (annual) – texting included.
- Business: ~$23/user/mo. Extra numbers ~$5/mo each; see pricing.
Who OpenPhone is best for: startups and small teams that want the most features for the lowest sensible price, with texting built in rather than bolted on.

4. GoTo Connect – Cheapest all-in-one voice and video
If you want voice and video together rather than just a phone line, GoTo Connect is the most affordable genuine all-in-one, bundling meetings, messaging and unlimited extensions at a fair per-user price with an easy visual call-flow editor.
GoTo Connect pricing (2026)
- Phone System: from ~$26/user/mo on annual billing.
- Pricing is now quote-based; watch for SMS and porting add-ons. Request pricing.
Who GoTo Connect is best for: small teams that want cheap all-in-one voice plus video meetings and simple administration, rather than a bare phone line.

Google Voice – Cheapest per user (with Google Workspace)
If your team already uses Google Workspace, Google Voice is the cheapest genuine per-user business phone at $10/user/mo (Starter), rising to $20 and $30 for ring groups and multi-level auto attendants. You get a business number, voicemail transcription and Google Meet, managed from the same admin console. The catch is that it needs a paid Workspace plan and international calling is metered, so it is cheapest only if you are already in Google’s ecosystem.
Is free VoIP worth it?
There are free and near-free options – residential services, app-only numbers and limited free tiers – but for a business they usually come with real trade-offs: capped minutes, no business texting, weak or no support, and numbers you do not fully control. If your business depends on the phone, a low-cost paid plan from Ooma or Grasshopper costs little and removes those risks. Free is best kept for testing or genuinely occasional use.
How to keep VoIP costs down
- Pick the lowest tier that includes the features you truly use – many providers charge extra for texting, recording, extra numbers and international minutes.
- Pay annually where possible; monthly billing is often 15-25% more.
- Avoid long contracts so you can move if a better deal appears.
- Watch add-on fees for diallers, AI and number porting, which quietly raise the effective price.
