PuchiDen Now Gives You a Number People Can Call

Before I get into it, a quick word on why a phone service is being announced on the Kafkai blog. PuchiDen is operated by Mirakuru Europa OÜ in Estonia, not by Kafkai Giken. The two are sister companies, and we co-develop PuchiDen with the Mirakuru team, so it sits on this blog alongside the things we build ourselves. If you came here for Kafkai and found a phone company, that is why.

When we launched PuchiDen in April, it was a payphone. You walked up to it in your browser, dialled a number anywhere in the world, and talked. What you could not do was give someone a number and have them call you back. A payphone does not have a number. That was the whole point of a payphone, and it was the whole point of PuchiDen.

The most common reply we got back was a version of the same question. "This is great, but can people call me on it?" Travellers wanted a number their bank would recognise. Small businesses wanted a local presence in a country where they had no office. People who had moved abroad wanted to keep a number their family back home could still dial without paying international rates.

As of 29 May 2026, they can. PuchiDen now offers virtual numbers: real phone numbers in other countries that forward incoming calls to whatever phone you already carry.

What a Local Number Actually Is

A virtual number is a real phone number, registered in another country, that anyone can dial. Someone calls it the way they would call any local number, and it forwards to a phone you choose. Your actual phone, your actual handset, sitting in your pocket wherever you happen to be.

The part I care about is how it forwards. The call comes through on the normal phone network, not over the internet. There is no app sitting between you and the caller, no "your call will begin in three, two, one" while a browser tab wakes up. A virtual number should behave like a phone, not like an app pretending to be one. The person calling you has no idea PuchiDen is involved, and neither does your handset. It just rings.

Your real number stays hidden from whoever is calling. They see the local number you rented. They never see the phone it lands on.

Where You Can Get One

We have opened with numbers in 10 countries. Monthly rental starts at:

Outbound calling still reaches more than 180 countries, the way it always has. Incoming numbers are the new part, and for now they live in the 10 countries above. The list reflects where we can provision a number cleanly and legally, not where we would like to stop.

This list will be update as we support more countries in the future. For the latest countries and pricing, refer to to the product update page on PuchiDen.

What It Costs

There are three parts to the price, and I would rather lay all three out than bury two of them.

1. A one-time setup fee of €20. This covers the identity check and the carrier provisioning that happen once, when your number is created.
2. The monthly rental for the country you picked, from the table above.
3. Per-minute charges on connected calls. The incoming leg (caller to your number) is a flat €0.06 a minute. The forwarded leg (your number to your actual phone) is charged at our standard outbound rate for wherever your phone is.

A worked example, because per-minute pricing is meaningless in the abstract. Say you rent a UK number for €5 a month and forward it to a mobile in Japan. Someone calls and you talk for five minutes:

• Incoming leg: 5 × €0.06 = €0.30
• Forwarded leg to a Japanese mobile: 5 × €0.26 = €1.30
• Call total: €1.60, on top of the €5 monthly rental.

Unanswered calls are free, the same as outbound. We bill connected calls only, with a one-minute minimum per call. Forwarding to a mobile costs more than forwarding to a landline, because it costs us more.

Who It's For

The same people PuchiDen was always for, plus a few new ones.

• People who moved and left a number behind. Keep a number in the country you came from, so family and old contacts dial a local call and reach you wherever you are now.
• Small businesses testing a market. A local number in a country where you have no office, for a few euros a month, with no SIM, no branch, and no contract with a local carrier.
• Anyone who needs a number their bank or government will accept. A real in-country number that forwards to you, instead of a foreign one their system quietly rejects.

It is still not a unified communications platform. It is a phone number that rings your phone.

The Honest Parts

A virtual number is more involved to set up than an outbound call, and I would rather tell you that now than have you find out after signing up.

• There is an identity check. Phone numbers are regulated, and the regulator wants to know who holds one. You will need a government photo ID and/or a business registration certificate, and for some countries proof of address or a local address on file. The whole process, including the check, usually takes about 7 business days. It is not instant, and I am not going to pretend it is.
• No emergency calls. A virtual number cannot reach 112, 110, 119, 911, or any other emergency service. Keep a real local line for that. This is not the tool for it.
• It is the public phone network, not a secure channel. Calls over the normal phone network are not end-to-end encrypted, and our telecoms provider processes the metadata needed to route a call at all. If you need encrypted voice, this is the wrong tool, and I will say so plainly.
• Call records are kept for 60 days, then deleted. We hold incoming call records for two months so you can see what came in, and then they are permanently deleted. There is no call recording.

How to Get One

1. Create an account with just an email address.
2. Email support from that address and tell us which country you want a number in.
3. Complete the identity check for that country.
4. Pick from the numbers we offer you.
5. The number goes live. Set where it forwards, and it starts ringing your phone.

That is the whole thing. You can read the full pricing and country detail on the PuchiDen virtual numbers page, and if you are new to PuchiDen, the original release announcement explains what it is and why we built it.
