Most businesses discover their phone plan decision wasn’t what they thought it was — carrier wireless plan versus VoIP system — only after they’ve already signed up for something. The two categories solve different problems and price completely differently. A verified July 2026 pricing index of 14 providers shows entry plans spanning $10 to $32/user/month, with four providers (GoTo Connect, RingCentral, 8×8, and some Zoom Phone tiers) refusing to publish prices at all. Here is every major option, what it actually costs, and which team fits which plan.
Key Takeaways — Straight Answers Before You Start Comparing
These are the questions that trip up most business owners when they start looking for a phone plan. In our testing across dozens of business accounts, the single biggest mistake is choosing between plans without first answering whether you need a VoIP system, a carrier plan, or both.
A VoIP phone system (RingCentral, Nextiva, Zoom Phone, Ooma, Dialpad, etc.) is software that turns internet connections into phone calls. Your team uses apps on computers, tablets, or existing smartphones — no SIM card swap required. Pricing is per user per month and typically runs $10–$35. A carrier business plan (T-Mobile, AT&T, Verizon) gives each user a physical SIM card and a cellular number tied to the carrier’s network. This is what you need for field workers, delivery drivers, or anyone who needs a dedicated mobile number with cellular coverage. Both can be “business phone plans” — they’re solving different problems. A hybrid business (some desk workers, some field staff) typically uses both: a VoIP system for office calls and carrier lines for mobile team members.
Four major providers in the July 2026 pricing index had no published rates: RingCentral (all RingEX tiers now show “Contact us”), 8×8 (pricing page shows headings with no numbers), GoTo Connect (all four plans are custom quotes), and some Zoom Phone tiers. This matters for two reasons. First, you cannot self-serve compare them — every evaluation requires a sales call, which is designed to create friction around leaving. Second, without a published market rate, the first quote you receive has no anchor. Ask any of these providers to confirm the full per-user rate plus any minimum seat requirements in writing before sharing business details. A Gartner Magic Quadrant listing doesn’t replace a written price.
In our testing of multiple VoIP accounts, the most common extra charges were: SMS/texting registration fees — Campaign Registry (TCR) compliance requires a one-time registration fee (Grasshopper charges $19.50 plus $1.50/month); toll-free number add-ons (not included in most entry plans); international calling rates (usually per-minute unless you add an international bundle); annual vs. monthly billing gaps (some providers charge 20–30% more on monthly billing); minimum seat requirements on premium plans; and CRM integration add-ons that are charged separately. For carrier wireless plans, the one-time Device Connection Charge (T-Mobile: $35/line) and regulatory fees ($1–$5/line/month) apply on top of the advertised rate.
Google Voice for Business starts at $10/user/month — but requires a paid Google Workspace subscription underneath it (starting at $7/user/month), making the true floor about $17/user/month for someone not already on Workspace. If you’re already paying for Workspace, Google Voice is the cheapest add-on available. For businesses not on Google Workspace, Zoom Phone’s metered plan at $10.50/user/month (annual billing) is the lowest transparent published price that includes calling. Grasshopper’s True Solo plan is $14/month flat for one user — the cheapest flat-rate option for solopreneurs or single-line businesses. magicJack for Business at $15.99/month covers basic calling with no annual contract.
Most modern VoIP plans are entirely app-based — mobile app, desktop app, and browser — with no hardware required. This works well for remote teams, home offices, and anyone comfortable with a softphone. If you have a reception desk, a conference room with a shared phone, or employees who strongly prefer physical handsets, most mid-tier VoIP plans (Ooma, Vonage Premium, Nextiva higher tiers) support desk phones — but hardware must be purchased separately or rented, typically adding $5–$15/user/month. We found in our testing that most businesses with under 10 employees operate entirely on apps without a single desk phone and don’t miss it. The case for hardware is mostly front-desk receptionists and shared conference room lines.
Yes — this is called number porting and virtually every major VoIP provider and carrier supports it. The process typically takes 2–10 business days depending on the losing carrier’s cooperation. You can keep your number with Nextiva, Ooma, RingCentral, Dialpad, OpenPhone, Zoom Phone, and all carrier plans. Grasshopper supports porting but charges for the process. Google Voice supports porting to and from Google Voice. The main risk is porting too early — initiate the port only after your new service is fully tested, because once a port is submitted, your old service will end automatically when the port completes, often with little notice.
Grasshopper is purpose-built for this use case — it charges per account, not per user, so a solo owner pays a flat $14–$18/month regardless of how many devices they use the number on. It gives you a separate business number that forwards to your personal cell, with voicemail transcription, custom greetings, and business texting. OpenPhone’s Starter plan at $15/user/month is the next-best option, adding a shared inbox and AI transcription that Grasshopper lacks. Google Voice at $10/user/month is the cheapest if you’re already paying for Google Workspace. We found Grasshopper wins specifically when you want a second number that behaves like a business line without changing how your cell phone works.
For most teams under 20 people, yes — both are designed primarily for call centers, sales floors, and support teams with high call volumes and complex routing needs. Aircall at $30/license/month makes most sense when you need deep CRM integration (Salesforce, HubSpot) with automatic call logging and analytics dashboards. RingCentral (which no longer publishes pricing) is enterprise-grade and often comes with implementation complexity that small teams don’t need and can’t afford to manage. If you’re a small team that just wants reliable business calling, video meetings, and SMS, Nextiva, Ooma, or Dialpad deliver the same core features at $15–$25/user/month without the sales process and minimum seat counts that come with RingCentral and Aircall.
The 14 Plans — VoIP & Cloud Phone Systems First
Pricing is per user per month on annual billing unless noted. Verified against live vendor pages July 2026 and the Phone2 Business Phone Pricing Index (monthly tracking of 14 providers).
Nextiva’s Core plan at $15/user/month (annual) gives you unlimited US and Canada calling, business SMS (100 messages/user/month), video meetings, call routing, and a toll-free number — the broadest entry-plan feature set in the mid-market. The Business plan at $23/user adds HubSpot and Salesforce integrations. In our testing, Nextiva’s 99.999% uptime claim held up better than comparable providers over extended monitoring periods, and its phone support response times were noticeably faster than Ooma and Dialpad. The main limitation: SMS caps on lower plans and no unlimited international calling without add-ons.
Ooma Office at $19.95/user/month is the clearest pricing choice in the category — three published tiers, no sales call required, no annual lock-in, no minimum seats. Ooma Office Pro at $24.95 adds video conferencing, call recording, and enhanced caller info. Office Pro Plus at $29.95 layers in CRM integrations, call queuing, and advanced analytics. We found Ooma’s physical desk phone compatibility the strongest in this price range — it’s the go-to choice for businesses with a reception desk or an employee who categorically refuses to use an app. The trade-off: Ooma’s mobile app is more basic than Dialpad or OpenPhone, and its AI features lag behind the newer entrants.
Dialpad Standard at $15/user/month (annual) includes AI call transcription on every plan — not just premium tiers — which is the clearest differentiator from Ooma and basic Nextiva. DialpadGPT generates call summaries and action items automatically. The Pro plan at $25/user adds multiple phone numbers per user, local numbers in 70+ countries, and API access. We found Dialpad’s mobile app the most polished in the under-$25 category — it behaves more like a native smartphone app than a VoIP adapter. The hidden cost to watch: the Enterprise plan has no published price, and adding international calling, extra numbers, and business intelligence tools each carries separate charges.
Zoom Phone’s metered plan starts at $10.50/user/month (annual) — the lowest published transparent price in the market. The US & Canada Unlimited plan at $16/user adds unlimited outbound calls. The killer use case is teams already paying for Zoom Workplace: adding Phone means one app handles meetings, chat, and calls, eliminating app sprawl. Gartner named Zoom a UCaaS Magic Quadrant Leader in 2026. The key limitation: the metered plan charges per minute for outbound calls, which gets expensive for high-volume calling. Zoom operates direct-in-dial (DID) numbers in about 20 countries — less global reach than RingCentral or 8×8. Some enterprise tiers require a sales quote.
OpenPhone’s Starter plan at $15/user/month (annual) includes AI-generated call transcripts, a shared team inbox for business numbers, and business texting with auto-replies. The Business plan at $23/user adds HubSpot, Salesforce, Zapier integrations, and analytics. Scale at $47/user covers enterprise needs. We found OpenPhone the easiest onboarding experience in the category — the team inbox concept, where multiple people can see and respond from a single business number, solves a specific pain point for customer-facing small businesses that Ooma and Grasshopper don’t address. The SMS experience is closer to iMessage than a traditional business phone app, which most under-30 founders prefer.
Grasshopper is the only major provider that charges per account rather than per user — making it the go-to for solo operators, single-line businesses, and small teams where everyone shares one business number. True Solo starts at $14/month (annual); Solo Plus at $25 adds unlimited extensions; Small Business at $55–$80 covers 4–5 numbers with unlimited users. Grasshopper forwards calls to your existing cell phone — no new app required — which is its core selling point. The hidden cost to watch: business texting requires a one-time Campaign Registry fee of $19.50 plus $1.50/month. Professional voice recording through Voice Studio runs $75 per recording. Not ideal for teams that want separate DID numbers per user.
Google Voice for Business starts at $10/user/month — but requires an active paid Google Workspace subscription (from $7/user/month) making the true all-in cost roughly $17+/user/month for a new user. The Team Starter plan covers up to 10 users; Standard at $20 adds ring groups, desk phone support, and eDiscovery; Premier at $30 adds advanced reporting and unlimited Google Meet recording. The integration with Gmail, Calendar, and Meet is the strongest available anywhere — if your team lives in Google apps, Voice is seamlessly embedded. The major limitation: no toll-free numbers, no business SMS with a national presence, and no annual billing discount — pricing is month-to-month only.
Vonage Business Mobile starts at $13.99/line/month — the lowest published monthly-only rate in the category — but this tier has no desktop app, limiting it to mobile use. Premium at $20.99 adds desktop and integrations; Advanced at $27.99 layers in call recording, voicemail transcription, and visual voicemail. Vonage’s strongest case is for businesses using its CPaaS (Communications Platform as a Service) APIs alongside the phone system — a combination that makes sense for tech companies building communication into their product. The company has decades of telecom history behind it. Note: Vonage does not offer an annual billing discount, which makes its pricing feel higher against annual-billing competitors.
8×8 supports direct-in-dial numbers in 55+ countries and virtual numbers in 120+ countries — the deepest international reach of any provider in this comparison. Its X2 plan starts around $24/user/month on annual billing (based on published comparison data, as 8×8 no longer displays prices on its own pricing page). The X4 plan at around $44 adds advanced call analytics, supervisor tools, and contact center features. The catch: 8×8’s pricing page exists in title only — every path routes to a custom quote. We found that 8×8’s first quote for a 10-seat team was negotiable, and businesses should treat that first number as an opening position, not market rate.
RingCentral RingEX is consistently rated a Gartner Magic Quadrant Leader for UCaaS, and the feature depth is real — 300+ integrations, 80+ country DID numbers, advanced analytics, and contact center capabilities on a single platform. The problem is every RingEX tier now shows “Contact us for pricing” — including the Core plan that was previously visible. This creates a sales-first evaluation process that is not appropriate for most small businesses. Based on industry tracking, RingEX typically quotes $20–$35/user/month at small-team scale, but the actual number depends heavily on team size and negotiation. Best suited for teams with 25+ seats who can justify the sales process. For smaller teams, Nextiva or Dialpad deliver 80% of the features at a visible price.
Aircall starts at $30/license/month and is purpose-built for outbound sales teams and inbound support centers. Every call is automatically logged in CRM, live coaching allows managers to whisper into active calls without the customer hearing, and real-time dashboards show call queue depth. We found Aircall overkill for most businesses under 15 people — its feature set requires a team willing to actively use its analytics, otherwise you’re paying $30+ for features nobody opens. The minimum three seats on entry plans is a barrier for tiny teams. Where Aircall earns its cost: a 10-person sales team where call-to-CRM automation saves 30 minutes of manual logging per rep per day.
GoTo Connect combines cloud PBX, video conferencing, and a contact center module in one platform with a consistently strong user review score on G2 and Capterra. The Phone System plan is commonly quoted at $26–$27/user/month; Connect CX at $32–$34 adds AI analytics and enhanced customer engagement tools; Contact Center at $80+ covers advanced routing. The frustration: GoTo removed self-serve pricing from its website in 2025, making every evaluation dependent on a sales rep. We found GoTo Connect’s AI features — particularly auto-summarization and post-call notes — among the most useful at this tier. Worth a quote for teams that need phone + contact center in a single bill without the enterprise overhead of RingCentral.
magicJack for Business offers a single plan at $15.99/line/month with no annual contract and approximately 20 standard business phone features including call forwarding, voicemail, hold music, and auto-attendant. It does not offer SMS/texting. For a business that needs a basic business line with minimal features and no annual commitment, magicJack is the lowest no-contract rate available from a recognizable provider. We found it works well for sole proprietors and single-location businesses where the phone is rarely the primary customer contact channel — a veterinary clinic that books mostly online, a contractor who primarily texts. It is not designed for teams, video calls, or CRM integration.
Carrier Business Plans — For Field Teams and Mobile Workers
These are physical SIM card plans from the Big 3 US carriers. They require a cellular device per user and charge per line, not per user login. They are the right choice when your team needs cellular coverage independent of internet access.
T-Mobile’s three business tiers — CoreMobile ($65/line, 1 line; $21/line at 12+ lines), ProMobile ($85/line to $34), SuperMobile ($100/line to $42) — include a 5-Year Price Guarantee on the base rate. The 10-line CoreMobile promotional offer at $200/month ($20/line) with $150 credit per line is the most competitive entry price available from any Big 3 carrier for teams of 10. America’s largest 5G network by coverage, per Ookla Speedtest. The non-negotiable cost: a $35 Device Connection Charge per line applies to every activation since March 2026, including Apple Store purchases. AutoPay discount requires a debit card or bank account — credit cards no longer qualify.
AT&T Business Unlimited plans start around $50/line/month for a single line, scaling down with more lines — competitive with T-Mobile at scale. AT&T’s FirstNet service, built for first responders and public safety, gives those organizations priority network access at a slight premium. Verizon Business plans start in the $45–$80/line range depending on tier and line count. Verizon’s myPlan structure allows more à-la-carte feature selection than T-Mobile’s bundled approach. All three carriers have active switching credits — when you’re evaluating, get a competitive written quote from all three before committing, as credits can meaningfully offset first-year costs.

Decision Guide — Match Your Situation to the Right Plan
Grasshopper wins if you want a second business number that rings through to your cell without changing your phone setup. Pay $14–$25/month flat regardless of how many devices you use it on. OpenPhone wins if you want shared visibility — you and a VA or a partner can both see and respond from the same business number, with AI transcripts and a cleaner inbox. Both avoid the per-user cost spiral that makes Nextiva and Ooma expensive at very small team sizes.
These three publish their prices, have no minimum seat requirements on entry plans, and deliver the full standard VoIP feature set. Choose Nextiva if you want the most complete entry plan (toll-free number included, voice + SMS + video at $15). Choose Ooma if anyone on your team needs a desk phone or you want the simplest month-to-month billing. Choose Dialpad if AI transcription of every call is a priority — it’s the only one that includes it on all tiers without an upgrade.
Don’t buy a separate VoIP system if you already live in a collaboration platform. Zoom Phone at $10.50/user/month (metered) or $16/user (unlimited US & Canada) integrates directly with Zoom Meetings and chat — one fewer app on everyone’s desktop. Google Voice at $10/user/month (on top of Workspace) embeds in Gmail, Calendar, and Meet. Neither is the best standalone phone system, but both are the best value for their respective ecosystems.
Aircall at $30/license/month pays for itself on a sales team if call-to-CRM automation saves each rep 20+ minutes of manual logging daily. Live call coaching via whisper mode, real-time dashboards, and automatic Salesforce/HubSpot logging are Aircall’s core case. Dialpad Pro at $25/user is the cheaper path to AI-powered call analytics if you don’t need Aircall’s depth of outbound dialing tools.
VoIP doesn’t work when you’re outside a wifi or strong data area. Field service teams, delivery drivers, construction crews, and mobile sales reps need carrier lines. T-Mobile’s 10-line CoreMobile promotion at $200/month total is the most aggressive entry price among the Big 3. Get written quotes from all three carriers before deciding — switching credits vary significantly and can determine the real Year 1 cost more than the base plan rate.
All pricing verified against live vendor websites and the Phone2 Business Phone Pricing Index (July 2026 edition), which tracks 14 providers monthly. Estimated prices for RingCentral, 8×8, and GoTo Connect are based on industry comparison data — these providers do not publish rates directly. VoIP prices are per user per month on annual billing unless noted. Carrier wireless prices are per line per month. All prices subject to change; confirm directly with each provider before signing.
