OpenPhone alternatives
Two things separate the OpenPhone alternatives: where they sell numbers, and how they bill. Sonetel sells in 78 countries from $1.99 a month, with no per-user fee unless you want the paid features.
The common case is a business in one country buying a number in another, so customers there dial a local line.
OpenPhone is now Quo
OpenPhone has rebranded to Quo, and openphone.com/pricing now redirects to quo.com. The site still gives its legal entity as OpenPhone Technologies, Inc. Nothing changed for customers on price or coverage. It still does not sell numbers outside the US and Canada.
Coverage and billing: the OpenPhone alternatives side by side
Sonetel has three plans. Basic carries no monthly plan fee, and Premium and Business are the paid tiers. Quo and Google Voice sell seats, while Grasshopper charges a flat rate for unlimited users.
| Sonetel | Quo, formerly OpenPhone | Google Voice | Grasshopper | |
|---|---|---|---|---|
| Numbers available in | 78 countries | US and Canada only | 14 countries | US and Canada only |
| How it bills | Per number on Basic; per user on Premium and Business | Per user | Per user, standalone or added to Workspace | Flat rate, unlimited users |
| Per-seat price, USD | $9.95 on Premium and $29.95 on Business, billed annually | $15 billed annually, $19 monthly, on Starter | from $10 a month | No per-seat price |
| Per-number price, USD | From $1.99 a month, or $1.89 a month billed annually | Extra numbers $5 a month | Included with the seat | Grasshopper's pricing page is restricted to US and Canada visitors |
| Numbers included | None on Basic; one per user on Premium, five on Business | One per user | One per user | A number and extensions |
What three seats actually cost
Like for like, it is Quo Starter against Sonetel Premium. Both bill per user, and both include a number each. Per seat that is $9.95 against Quo's $15, both billed annually. So a team of three pays $45 a month on Quo, against three times the Sonetel rate.
Quo's seat brings unlimited US and Canada calling, subject to its fair-use policy. Sonetel's brings free calls to around 40 countries inside a monthly bundle: 2,000 minutes per user on Premium and 5,000 on Business, pooled across the account rather than capped per person. It also brings the AI features described further down.
Sonetel Basic is cheaper if three of you share one number and skip those features. That is one number from $1.99 a month with no plan fee, and forwarded calls metered on top from $0.005 a minute.
Where Quo still wins
Quo is built around a shared texting inbox, where a team works one number together. Sonetel's app sends and receives SMS from your business number, where the number supports it, but there is no shared team inbox. If that workflow is why you pay OpenPhone today, switching costs you it.
Quo includes unlimited US and Canada calling in its price, and Grasshopper includes unlimited calls in its flat rate. Sonetel meters forwarded calls on Basic. And the per-seat saving narrows the moment you want Sonetel's paid features, because Premium and Business bill per user too.
Where Sonetel differs from the other OpenPhone alternatives
-
A number where your customers are. Sonetel sells local, mobile and toll-free numbers in 78 countries. Every country and its price is listed before you buy.
-
Billed per number on the pay-as-you-go plan, per user on the paid ones. On Basic you pay for numbers and calls only. So three colleagues sharing one line pay for one number: from $1.99 a month, or $1.79 on a three-year term, which Basic offers and the paid plans do not. Premium is $9.95 per user per month billed annually, and Business is $29.95. Want the AI features and you are paying per seat again — though for a seat that is under Quo's and includes a number each.
-
AI that writes up your calls. Premium and Business add call summaries, transcription, draft follow-up emails and meeting minutes. Customer call analysis scores each customer call and suggests improvements, and both plans record calls and offer a voice menu for incoming callers. Quo puts summaries for all calls on its Business plan, at $23 per user per month billed annually. On its $15 Starter plan they cover only calls handled by Sona, Quo's AI answering agent.
-
Cheaper calls once you are on a paid plan. Premium and Business include free calls to around 40 countries, inside the monthly minute bundle above. Premium cuts the per-minute rate elsewhere by roughly 40% against Basic, and Business by roughly 50%. Basic itself is pay-as-you-go: forwarded calls are charged per minute from $0.005, answering in the app avoids that forwarding cost, and inbound SMS and voicemail reach you by email where the number supports it.
-
Bring the number you already have. You can port an existing number to Sonetel in many countries. Check the porting page before you cancel with your current provider, because the number has to stay active there until the port completes.
Getting a number running
- Sign up on the website. You choose your number during signup, and the web signup offers more number options than the app does.
- Then get the app. The Sonetel app runs on iOS, Android, Mac, Windows and Linux, and there is a web app.
- Point calls where you want them. Forward to any phone at per-minute rates from $0.005, or answer in the app and avoid the forwarding cost.
- Turn on the AI features in the app, if you are on Premium or Business. Summaries and transcripts appear there once a call ends.
The company behind Sonetel
Sonetel has run the service since 2009. It is listed on Nasdaq First North Growth Market in Stockholm, ticker SONE, with more than 34,000 businesses as paying customers in 170+ countries.
Choosing between the OpenPhone alternatives
Quo and Grasshopper both stop at the US and Canada. If your customers are elsewhere, the choice narrows to Sonetel or Google Voice: 14 countries against 78. Grasshopper suits a US team that wants one flat bill and no per-seat arithmetic, and Google Voice suits a team already inside Google Workspace.
If your team shares one line and skips the AI features, Basic bills you for the number and the calls you forward, with no plan fee. Most number types come with a free trial, so you can hear the number ring before you pay.
