Who it is for

Who each one is for

WiseCall if you want 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 and you want a big minute bundle. Solo is built around 1,000 minutes. Team adds bring-your-own numbers 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

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

WiseCall

20 inbound AI calls, no card, to test the setup.

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. You can hear Ava answer a real call before you start the 20 free calls.

Phone line

WiseCall includes a number. No phone system to buy. Already on a PBX? Connect it.

Fonio gives you a Fonio number. Bringing your own numbers starts on their Team plan.

If you are a UK practice that does not want another phone contract, that is the whole product difference for a lot of buyers.

Billing and phone line

WiseCall: a number included, billed in pounds, on 30-day rolling.

Fonio: billed in euros, with a 30-day money-back. That is a real answer if you already work in euros. It is a different answer for a UK dental practice comparing the phone line and the invoice.

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

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.

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.

Not with WiseCall.
