The Real Cost of 'Free' Phone Systems

Google Voice, Teams Phone, free VoIP apps — they cost $0, but they’re not free. Here’s what you actually give up and when free is genuinely fine.

Free Is a Real Option. Let’s Be Honest About That.

We sell phone service for a living, so you might expect us to trash free alternatives. We’re not going to do that. For some businesses, free phone tools are genuinely fine — and we’d rather be honest about that than pretend every two-person startup needs a full hosted PBX.

But “free” is doing a lot of work in that sentence. The dollar cost is zero. The actual cost — in limitations, in data, in things you don’t get — is real. And most of the content out there about free business phone systems is written by the free providers themselves or by affiliate sites that get paid to recommend them.

So here’s an honest look at what you’re getting, what you’re giving up, and when each tradeoff makes sense.

Google Voice: The One Everyone Tries First

Google Voice is the default “free business phone” for a lot of small businesses and freelancers. And for a solo operator who just needs a number that isn’t their personal cell, it’s actually pretty decent.

What you get for free:

  • A phone number (US only)
  • Calling and texting to US and Canada
  • Voicemail with transcription
  • Basic call forwarding
  • Works from your phone, computer, or browser

What you don’t get:

  • Number porting (you can port a number in to Google Voice, but the free tier doesn’t support it — you need the paid Workspace tier)
  • Multiple extensions or users
  • Call routing, ring groups, or auto-attendants
  • Anything resembling a business phone system
  • Phone support (it’s Google — there is no phone support)
  • Any guarantee of service continuity (Google kills products regularly)
  • Toll-free numbers
  • Fax capability

The data question: Google Voice is a Google product. Google’s business model is advertising, which means data. Google’s privacy policy allows them to collect and analyze information from their services to serve ads and improve products. When you make Google Voice your business phone, your call metadata — who you called, when, how long, how often — becomes part of Google’s data ecosystem.

Google says they don’t use Google Voice audio content for ad targeting. But your call patterns, contacts, and usage data are fair game under the general Google Privacy Policy. If you’re in an industry where client confidentiality matters — legal, healthcare, finance — this is worth thinking about. You’re not paying with money. You might be paying with information.

When it’s fine: You’re a freelancer, solo consultant, or very early startup. You need a number that’s not your cell. You don’t need to port an existing number. You don’t have clients calling a main line expecting a receptionist.

When it’s not: You have more than a few people. Clients call a main number. You need call routing. You need to port your existing number. You’re in a regulated industry.

Microsoft Teams Phone: “Free” With a Giant Asterisk

Teams Phone is interesting because a lot of businesses think they already have it. They don’t — or rather, they have Teams (which comes with Microsoft 365), but they don’t have Teams Phone (which costs extra).

What you get with Microsoft 365:

  • Teams chat, video, screen sharing
  • Teams-to-Teams voice calls (internal only)
  • No ability to make or receive calls to/from regular phone numbers

What you need to pay for to actually make phone calls:

  • Teams Phone license: ~$8/user/month
  • A Calling Plan or connection to the phone network: ~$7-15/user/month on top of that
  • Or an Operator Connect / Direct Routing setup through a third party

So the “free” phone system through Teams actually costs $15-23/user/month — which is in the same range as a dedicated hosted PBX provider. You’re paying VoIP prices for a phone system that’s bolted onto a collaboration platform.

The tradeoffs:

  • Call quality depends on your Teams infrastructure and internet, which is fine for most offices but can be inconsistent for remote workers
  • Phone features (auto-attendant, call queues, voicemail) exist but are more limited and harder to configure than dedicated phone platforms
  • You’re locked into the Microsoft ecosystem — if you ever leave M365, your phone system goes with it
  • Admin experience is… Teams admin. If you’ve managed Teams, you know what that means
  • E911 configuration is available but buried in the admin center

When it makes sense: You’re already deep in the Microsoft ecosystem, your phone needs are simple, and you value having everything in one vendor over having the best phone system.

When it doesn’t: You need sophisticated call routing, you want a provider that specializes in voice, or you don’t want your phone system’s fate tied to your Microsoft licensing decisions.

Free VoIP Apps (TextNow, TextFree, Dingtone, etc.)

There are a bunch of apps that offer free phone numbers and calling. They’re aimed at consumers, not businesses, but we see small businesses using them — usually because someone needed a number fast and grabbed the first free thing they found.

What you get:

  • A phone number
  • Basic calling and texting
  • It works (mostly)

What you give up:

  • Any pretense that this is a business tool
  • Number permanence (free numbers can be reclaimed if you don’t use the app regularly)
  • Call quality consistency
  • E911 reliability (some of these apps have minimal or no E911 implementation)
  • Ad-free experience (most free-tier apps show ads)
  • Your data (these apps are funded by advertising and data monetization — your call patterns, contacts, and usage are the product)

The data reality: These apps are the clearest example of “you are the product.” They’re free because they monetize your data and attention through ads. The privacy policies are typically broad — they collect call metadata, contacts, usage patterns, device information, and share it with advertising partners. If you’re putting client calls through one of these apps, your clients’ phone numbers and call patterns are being fed into an ad network.

When it’s fine: Personal use. A temporary number for a Craigslist listing. A side project that isn’t a real business yet.

When it’s not: Any scenario where you’re representing a business to customers, clients, or partners.

The Hidden Costs Nobody Mentions

Beyond the specific platforms, there are costs to “free” that apply across the board:

No Number Porting (or Painful Porting)

If your business number is on a free platform and you outgrow it, getting that number to a real business phone provider can range from annoying to impossible. Some free services don’t support outbound porting at all — your number is stuck there. Others support it but make it difficult. Either way, the longer you build your business identity around a number on a free platform, the harder it is to leave.

This is the same lock-in dynamic we described in our piece on VoIP price increases, except worse — because at least paid providers are legally required to port your numbers. Free services sometimes aren’t classified the same way under FCC porting rules.

No Redundancy or Business Continuity

When Gmail goes down, your email is down. When Google Voice goes down, your phone is down. Free services don’t offer SLAs, uptime guarantees, or redundancy. There’s no one to call. There’s no status page you can trust. You just wait.

For a freelancer, this is an inconvenience. For a business with customers trying to reach you, it’s lost revenue. Our business continuity guide covers what real redundancy looks like.

No Compliance

If you’re in healthcare (HIPAA), legal (attorney-client privilege), finance (SEC/FINRA record-keeping), or education (FERPA) — free phone tools almost certainly don’t meet your compliance requirements. Google Workspace has a BAA option for HIPAA, but the free tier of Google Voice does not. Teams Phone can be HIPAA-compliant under the right licensing, but the free tier of Teams is not.

Using a non-compliant phone system isn’t just risky — in some industries, it’s a violation that comes with real penalties.

No E911 You Can Trust

We wrote a whole piece on VoIP 911 because it’s that important. Free VoIP apps vary wildly in their E911 implementation. Some route 911 calls properly. Some don’t support 911 at all. Some technically support it but make the address registration so obscure that nobody sets it up correctly. If you have employees using free VoIP apps as their business phone, make sure you understand what happens when they dial 911.

So When Is Free Actually the Right Call?

Free is fine when:

  • You’re a one-person operation and just need a business number
  • You’re testing a business idea and don’t have customers yet
  • You need a temporary number for a specific project
  • You’re genuinely fine with the limitations and have thought through the tradeoffs

Free stops making sense when:

  • You have employees who need extensions
  • Clients call a main number and expect someone to answer
  • You need to port an existing business number
  • You’re in a regulated industry
  • You need call routing, auto-attendants, or voicemail distribution
  • Uptime actually matters to your revenue
  • You care about where your call data goes

The moose-take most businesses make isn’t starting with free — it’s staying with free too long. The longer you build on a free platform, the more painful the eventual migration, and the more you’ve normalized limitations that a real phone system would have solved months ago.

What Real Phone Service Actually Costs

Here’s the thing that surprises people: a proper business phone system isn’t that expensive. We’re not talking about the $45/user/month enterprise platforms (though those exist). A well-run hosted PBX provider — one that owns their own platform and isn’t just reselling someone else’s system — can typically serve a small business for less than you’d think. Especially if they’re not locked into rigid per-seat pricing.

The gap between “free with major limitations” and “proper business phone service” is often smaller than people assume. And the gap between what you get is enormous.

Outgrowing your free phone setup? Drop us a line. We’ll tell you honestly whether you need to upgrade yet — and if you do, we’ll make the transition painless. We can usually port your number even from free services, though it sometimes takes a little extra moose-cle. No pressure, no 47-slide deck.
