Brochure
Your phone number, anywhere in the world.
Leave Tahaa at home with your SIM card. Calls and texts to your number reach the app on your phone, wherever you are, over Wi-Fi or data. No roaming, no missed codes.

How it works
- 1Your SIM, at home
Put your SIM card in Tahaa and plug it in at home. It connects to your Wi-Fi and to your mobile network, like a phone that never leaves.
- 2Add it in the app
Scan the QR code on the box with the Tahaa app. That’s all: no settings, whatever your operator.
- 3Go anywhere
Your calls ring in the app and your texts arrive there, wherever you are. Call and text from your own number, too.
Your number, without the SIM in your phone
Banks, doctors, family: everyone reaches you on the number they know, even when you’re abroad.
Security codes sent by text arrive in the app, wherever you are. No more locked accounts on holiday.
The app uses Wi-Fi or any data plan. Your SIM stays home, on its usual plan.
Calls ring like any call, even on a locked phone, and go out from your own number.
Send and receive texts and picture messages, with your contacts’ names.
Notifications are encrypted for your phone alone. Your messages aren’t sold or analysed.
Made for
On the move
- Travellers. Weeks away without losing a call or a code.
- Expats. Keep the number your bank and your family know.
- Second homes. One number, wherever you live this season.
A second number
- A public number. Give out the Tahaa number; your own SIM stays in your phone for the people close to you.
- Work. A work line on your own phone, with no second phone in your pocket.
- Selling online. A number for ads and marketplaces that never reveals your personal one.



Private by design
Calls and messages are encrypted end to end between your Tahaa and your phone: not even our servers can listen to your calls or read your texts. Notifications are encrypted for your phone alone, and your messages are never sold or analysed. The service is hosted in Paris, France.
