You switch carriers
Number portability works, but it takes time, demands paperwork, and sometimes leaves you unreachable during the switch.
Coming soon — launching late 2026
OneNumber gives you a universal phone number you keep forever — no matter the carrier, the country or the SIM card. One payment. No subscription.
2,847 people are already on the list. Priority access and founder pricing guaranteed.
The problem
It's tied to a carrier, a country, a piece of plastic. The day one of the three changes, everything gets complicated.
Number portability works, but it takes time, demands paperwork, and sometimes leaves you unreachable during the switch.
A local SIM costs less, but forces you to juggle a second number. Your contacts no longer know where to reach you.
Broken card, stolen phone, switching to eSIM: every time, your phone identity hangs on a fragile object.
OneNumber separates your number from everything else. The number becomes yours — for good.
This isn't a niche annoyance. It's a structural flaw in how 5.7 billion people hold the single most important identifier they own.
How it works
Setup happens once. After that, your number never moves — whatever happens.
Choose a new OneNumber or transfer your current number. It's registered in your name, for good.
OneNumber layers over your SIM card through our carrier agreements. Your calls and texts arrive normally, with no middleman app.
New carrier, new country, new SIM: you re-link your account in minutes. Your number never changes.
Why OneNumber
You're no longer locked to a carrier. Compare, negotiate, switch whenever you want — your number stays your fixed point. It follows you, not the other way around.
1 number, for life
You pay once. No subscription, no renewal, no nasty surprise on the bill.
A number designed to follow you across Europe, with no second number to manage.
Switch SIM cards in minutes from your account. No paperwork, no waiting.
Your number is encrypted and locked against hijacking. A security layer your regular carrier doesn't give you — built in by design.
Global coverage
OneNumber works across 67 countries from day one — all of Europe, 17 African nations, and key Asian markets. Every new carrier agreement extends the map.
Carrier partnerships are active. Coverage expands with every new agreement; hover over the map to explore individual countries and their carrier coverage.
Traction
Most pre-launch startups pitch a promise. We're pitching a machine that's already turning — signed contracts, an organic audience, and a regulatory path that's locked.
people on the waitlist
Built with €0 in paid acquisition. Every sign-up is organic — proof of pull, not push. The cheapest growth curve an investor will see this quarter.
carrier agreements signed
Vodafone, Orange, Deutsche Telekom and SoftBank — covering 67 countries on day one. The moat most competitors never cross.
regulatory runway secured
Number portability is mandated by EU Directive 2018/1972. The legal groundwork across ARCEP, BNetzA and MIC is already mapped.
to first paying users
Beta-ready architecture. The waitlist converts the moment we open — no cold start, no audience to buy.
Business model
Customers pay once. Carriers pay us per activation. The number lives forever — and so does the relationship. No subscription treadmill, no churn cliff.
€89–149 one-time for a number they keep for life.
A per-activation fee on every network the number touches.
Fixed, negotiated costs. No marginal-cost spiral as we scale.
The numbers
A hockey stick built on activations, not hope. Break-even by Q4 2027, then the flywheel: every market we open compounds the last.
Competitive landscape
Carriers lock you in. Voice apps add a second number. eSIM startups sell data, not identity. Nobody else makes the number itself permanent, portable and yours.

50,000+ paying users. €4.5M+ ARR. 99% net retention. 6+ carrier agreements. Target: €60-80M valuation.
4 carrier partnerships covering 67 countries. The hardest part — regulatory and legal — is done.
Nobody abandons their phone number. Retention isn't 95% — it's structurally 100%.
One-time €89–149 payment. Fixed per-activation carrier fees. Capital-efficient from day one.
EU law mandates number portability. We don't need permission — we exercise a right.
The objective
The phone number is the last piece of personal identity still owned by a third party. Email outlived its providers. Domains outlived their registrars. The number is next — and we intend to be the layer it runs on.
All of Europe plus the UK, where portability is law and our four carriers already operate. Become the default way Europeans hold a number.
Activate the Orange African footprint and the SoftBank Asia-Pacific corridors — the routes expats and global workers actually travel.
License the OneNumber rail to banks, enterprises and carriers themselves. The number stops being a product and becomes infrastructure.
We don't need to win everyone. We need to win the 180 million people who already live between carriers and borders — and the math takes care of the rest.
The endgame for investors
Telecom groups, fintech platforms and identity providers racing to own the number layer.
Messaging & identity startups acquired at 8–15× revenue in the last cycle.
A €23M post-money entry against a category that produces billion-euro outcomes.
Four contracts signed. Sixty-seven countries live. Zero churn by design. The only variable left is how fast we move.

Frequently asked questions
Yes. OneNumber relies on number portability, a right governed by European telecommunications regulation, and on agreements made directly with carriers.
Your OneNumber stays the same. You insert a local SIM card, link it to your account in a few minutes, and your calls keep arriving on the same number.
No. OneNumber is a one-time payment. You pay your voice and data plan to the carrier of your choice, separately. We never bill the number per use.
You can transfer your existing number to OneNumber — it then becomes your number for life — or choose a new number. The transfer is included in founder pricing.
The European launch is planned for late 2026. Waitlist members are activated first and keep their founder pricing.
Yes. Your number is encrypted and protected against SIM hijacking. We comply with GDPR and never resell personal data.
