But low monthly pricing alone won't tell you which service is actually "cheap." Call quality, included features, hardware costs, taxes, support quality, security, and scalability all factor into your real business cost. This guide compares five providers on those exact criteria: TelcoSolutions, Zoom Phone, Google Voice, Ooma Office, and Grasshopper.
TL;DR
- Cheap VoIP means affordable internet calling that still delivers reliability, call management, and real support.
- Compare total monthly cost, not just the advertised base rate.
- Best fits by need: TelcoSolutions (tailored setup); Zoom Phone or Google Voice if you already use those apps.
- Simpler needs: Ooma Office for basic SMB calling; Grasshopper for a dedicated number only.
- Free and bargain tiers often skimp on number ownership, emergency calling, integrations, or support.
Overview of Cheap VoIP Phone Services in the US Market
VoIP converts your voice into digital data and routes it over an internet connection instead of copper phone lines. That's why employees can take calls on desk phones, laptops, mobile apps, or analog adapters connected to existing handsets.
Cost factors worth comparing before you sign anything:
- Per-user or per-line monthly fees
- Metered versus unlimited calling plans
- Taxes and regulatory surcharges (often 5-20% of your bill)
- Phone hardware costs or leases
- Additional number and toll-free charges
- International calling rates
- Setup fees, contracts, and cancellation terms
- Premium add-ons like call recording or AI transcription
Free consumer apps, free numbers, and residential VoIP are built for individuals—not businesses fielding customer calls. A business phone system typically needs:
- Call routing and professional voicemail
- Number porting and E911 compliance
- Admin controls and support that actually picks up
Keep that distinction in mind as we run through the shortlist.
Best Cheap VoIP Phone Services in the US
Each provider below is weighed on real total cost, core business features, reliability, ease of use, and fit for different company sizes.
TelcoSolutions — Best for Tailored Business VoIP
TelcoSolutions is a nationwide telecom consultancy with access to 300+ providers. It matches businesses to VoIP, internet, and related connectivity solutions built around real call volume and workflow, not a generic tier.
That approach fits companies replacing an aging phone system or supporting remote and multi-site teams. TelcoSolutions handles comparison shopping, implementation, billing, and ongoing support.
What TelcoSolutions offers:
- Custom-quoted business phone systems billed monthly per user, with lines added or removed anytime and no long-term contract required
- Mobile integration that turns smartphones into full business lines
- Auto-attendants, call forwarding, and routing for on-site or remote staff
- CRM, ERP, and ticketing-system integrations through a central admin dashboard
- Security features such as encrypted call traffic, MFA, and custom user roles through matched providers
- Expansion across multiple locations without replacing hardware
Best fit: Small offices outgrowing legacy PBX, call-heavy service businesses, and multi-site organizations without dedicated in-house IT. Internal data shows 92% of matched customers saved 20% or more on telecom bills. Per-user pricing depends on your quote, so confirm inclusions before you commit.
Zoom Phone — Best for Teams Already Using Zoom
If your team already lives in Zoom Meetings, adding Zoom Phone can be the most budget-friendly way to get business calling without switching platforms.
Pricing (2026):
- US/Canada Metered: $10/user/month, billed annually
- US/Canada Unlimited: $15/user/month billed annually, or $18/user/month billed monthly
- Pro Plus: $18.33/user/month; Business Plus: $22.49/user/month
All tiers include a domestic number, SMS/MMS, 50 pages/month of online fax, call recording, and admin controls. International calling is metered separately, and Zoom states a 99.999% uptime SLA for its phone service.
Watch for:
- Taxes and regulatory fees billed separately
- Non-cancelable, generally non-refundable contract terms during your billing period
- AI features (call summaries, voicemail prioritization) aren't clearly mapped by tier
Best fit: Zoom-centric teams and growing SMBs comfortable with tiered pricing. PCMag rated it 4.0/5 (Excellent) for reliability, while flagging confusing plan structures.
Google Voice — Best for Google Workspace Users
Google Voice is a lightweight option that plugs directly into Google Workspace, handling calling, texting, and voicemail through apps you likely already use.
Pricing:
- Starter: $10/month (up to 10 users on Workspace)
- Standard: $20/user/month (unlimited users)
- Premier: $30/user/month (unlimited users, advanced reporting)
Voicemail transcription and call recording are included on every tier; automatic recording is Premier-only. Auto attendants start at Standard. Paid subscriptions include 911 support and 24/7 assistance; free personal Google Voice does not.
Limitations:
- Desk-phone support is limited compared to full UCaaS platforms
- No AI sentiment analysis or skill-based routing
- Best for lighter call volumes, not high-traffic sales or support desks
Best fit: Google-centric small teams and professional offices already on Workspace. PCMag scored it 3.0/5 (Average): easy setup, but thin on advanced features once you outgrow the basics.
Ooma Office — Best for Straightforward Small-Business Calling
Ooma Office keeps things simple: core calling features, no long-term contract, and a clear pricing chart.
Pricing:
| Tier | Price/user/month | Adds |
|---|---|---|
| Essentials | $19.95 | Virtual receptionist, one free toll-free number, mobile app |
| Pro | $24.95 | Desktop app, 250 texts/month, call recording |
| Pro Plus | $29.95 | AI transcription, CRM integration, call queues, hot desking |
Additional numbers run $9.99/month plus taxes; toll-free plans start at $9.95/month for 500 minutes. Hardware is optional, with adapters starting around $69.99 and IP phones from $59.99.
Good to know:
- Enabling E911 costs nothing extra, but Ooma requires a physical service address (no PO boxes)
- Setup and cancellation terms aren't published in detail, so ask before signing
Best fit: Small offices wanting straightforward setup without a steep learning curve. PCMag gave it 3.5/5 (Good), citing reliability but limited AI and monitoring tools for growing teams.
Grasshopper — Best for a Simple Dedicated Business Number
Grasshopper layers a business number onto your existing mobile phone instead of replacing it with a full phone system. That is the appeal for solo operators who do not want a separate desk phone.
Pricing (billed annually):
- True Solo: $14/month equivalent ($168/year) — 1 user, 1 number
- Solo Plus: $25/month equivalent ($300/year) — unlimited users, 3 extensions
- Small Business: $55/month equivalent ($660/year) — unlimited users, 4 numbers, unlimited extensions
Additional numbers cost $9/month; extra extensions are $3/month on Solo Plus (unlimited on Small Business). A 7-day free trial requires no credit card.
Trade-offs:
- No CRM integrations or contact-center features
- Desk-phone compatibility and tier-level E911 terms aren't clearly published
- Call Blasting ($9/month) and Voice Studio ($75/order) are separate add-ons
Best fit: Solo entrepreneurs and small teams that need a professional number separate from a personal cell. PCMag scored it 3.0/5 (Average): intuitive, but pricier than expected for what you get.
How We Chose the Best Cheap VoIP Phone Services
We didn't rank providers by advertised price alone. Instead, we compared:
- Total cost of ownership — subscription fees, taxes, hardware, porting, setup, and contract terms
- Core functionality — call routing, auto attendants, voicemail, SMS, E911, mobile and desk-phone access
- Reliability and security — published uptime commitments, support hours, and independent reviews
- Usability and scalability — onboarding time, admin controls, and whether the system grows with you
Choosing the cheapest plan today can cost more later if you outgrow it fast. Number porting alone can run up to $30 per number, and carrier registration fees add roughly $19 more. Those costs add up if you switch providers again within a year.
Conclusion
The cheapest VoIP service is the one that delivers the calling, routing, security, and support your business actually needs at a predictable total cost, not just the lowest sticker price. Switching from a landline to VoIP can cut telecom costs by 50-75%, but only if you account for taxes, hardware, and add-ons upfront.
Before signing anything:
- Test call quality with your actual internet connection
- Confirm number-porting and E911 details in writing
- Calculate the full monthly bill, not just the base rate

Frequently Asked Questions
Is there a free VoIP service?
Some consumer apps and limited business tiers are free, but check restrictions on number ownership, calling destinations, emergency services, and support before relying on one for business use.
Can I get a free VoIP phone number?
Free numbers exist through apps like Google Voice's personal tier, but they often lack portability, E911 support, and business features. Confirm ownership rules and inactivity policies first.
What are some good budget VoIP phones?
Options range from affordable IP desk phones (often $50-$100) to free softphone apps and analog telephone adapters that connect existing handsets. Always confirm compatibility with your chosen provider before buying.
Do I need a landline for a VoIP phone?
No. VoIP runs over your internet connection instead of a landline. You'll need reliable bandwidth, backup power for outages, and confirmation that emergency calling works with your setup.
Why would someone use VoIP instead of a cell phone?
VoIP offers dedicated business numbers, call routing, shared lines, and team-wide admin controls that a single cell phone plan can't match. It's built for multiple users, not one person.
Does anyone still use VoIP?
Yes. Businesses rely on VoIP for flexible remote work, multi-user calling, and centralized administration at lower infrastructure costs than traditional phone lines. A stable internet connection and responsive provider support remain essential.
