Who it is for
Who each one is for
WiseCall if you want UK hosting, a pound invoice, and a number without buying a second phone system. Dental, legal, property, trades, care. Same agent when the enquiry comes in by email or WhatsApp, not only the phone.
Fonio if you already work in euros, you want a big minute bundle, and EU hosting is fine. Solo is built around 1,000 minutes. Team adds SIP and outbound campaigns.
If the only number that matters is the cheapest unlimited minutes in pounds, neither of these is the cheapest. That is Hey Jodie, on the UK comparison page.
Price
Price
WiseCall Starter is £99 a month on 30-day rolling, or £84.15 if you pay yearly. 100 AI calls. Professional is £199 (£169.15 yearly) for 300. Business is £399 rolling, £339.15 yearly, for 750 and up.
Fonio Solo is €99 a month, €84 yearly, for 1,000 minutes. Team is €299 (€254 yearly) for 3,000 minutes. Scale starts at €499 (€424 yearly). Extra Solo minutes are €15 per 100.
A minute is not a call. A two-minute enquiry and a ten-minute one both count as one WiseCall AI call. On Fonio they do not.
Trial
Trial
Fonio
30-day money-back.
Different bets. Ours is try it on real inbound calls before you pay. Theirs is pay, then claim a refund if you hate it.
Phone line
Phone line
WiseCall includes a number. No phone system to buy. Already on a PBX? Connect it.
Fonio gives you a Fonio number. SIP trunk (bring your own numbers) starts on Team.
If you are a UK practice that does not want another VoIP contract, that is the whole product difference for a lot of buyers.
Data
Data
WiseCall: UK infrastructure and hosting.
Fonio: main server in Nuremberg. They sell GDPR and EU hosting. That is a real answer for a German clinic. It is a different answer for a UK dental practice that asked where the recordings live.
Channels
Channels
WiseCall is one agent on phone, email, WhatsApp, live chat and SMS, with allowances on every plan.
Fonio is a phone product first. WhatsApp is a separate plan family on their pricing page.
If your customers WhatsApp the office after they miss you on the phone, count that as a requirement, not a nice extra.
Dental
Dental
WiseCall books eligible appointments into Dentally. It does not give clinical advice. Emergencies go to your rules.
Fonio books into a calendar and talks GDPR. Fine. It is not a UK practice-management story.
Honesty
What we will not claim
Fonio has more customers, more funding, and more pages on their site. True. That does not make them the UK option.
We do not have a wall of named case studies yet. Fonio does. If that is your buying test, they will look further along.

FAQ
Questions
Is WiseCall cheaper than Fonio?
Starter vs Solo is roughly the same headline. The units differ (calls vs minutes) and the invoice currency differs. Count your real call length before you pick the cheaper one.
Does Fonio work in the UK?
They have a UK number on the site and they are hiring in London. The product and the company are still DACH. Hosting is still Germany.
Can I keep my number?
Usually, with WiseCall, by porting or forwarding. We confirm when we set you up.
Do I need a phone system?
Not with WiseCall.
