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
One number.
For life.
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
Your number isn't really yours.
It's tied to a carrier, a country, a piece of plastic. The day one of the three changes, everything gets complicated.
You move abroad
A local SIM costs less, but forces you to juggle a second number. Your contacts no longer know where to reach you.
You lose or change your SIM
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.
How it works
Three steps. Then never again.
Setup happens once. After that, your number never moves — whatever happens.
-
1
You reserve your number
Choose a new OneNumber or transfer your current number. It's registered in your name, for good.
-
2
You link it to your line
OneNumber layers over your SIM card through our carrier agreements. Your calls and texts arrive normally, with no middleman app.
-
3
You change everything but your number
New carrier, new country, new SIM: you re-link your account in minutes. Your number never changes.
Why OneNumber
A free number, at last.
Total independence
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
One payment
You pay once. No subscription, no renewal, no nasty surprise on the bill.
European coverage
A number designed to follow you across Europe, with no second number to manage.
Instant portability
Switch SIM cards in minutes from your account. No paperwork, no waiting.
Anti-SIM-swap protection
Your number is encrypted and locked against hijacking. A security layer your regular carrier doesn't give you — built in by design.
Our roadmap
Five agreements. A head start.
Our priority: securing compatibility agreements with Europe's five largest networks. Once those partnerships are signed, OneNumber becomes the standard — and no one can catch up.
- Native compatibility targeted with Europe's major networks
- Goal of continuous coverage across 27 countries
- Carrier negotiations underway — exclusive agreements first

Frequently asked questions
What you want to know.
Is the OneNumber service legal?
Yes. OneNumber relies on number portability, a right governed by European telecommunications regulation, and on agreements made directly with carriers.
What happens if I change country?
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.
Do I have to pay a monthly subscription?
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.
What happens to my current number?
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.
When will the service be available?
The European launch is planned for late 2026. Waitlist members are activated first and keep their founder pricing.
Is my data protected?
Yes. Your number is encrypted and protected against SIM hijacking. We comply with GDPR and never resell personal data.
