Onoff

Get a second phone number instantly with Onoff — no extra SIM card or second device needed. Simply download the app, subscribe, and start using a dedicated mobile number alongside your primary line, all from a single smartphone.

Separate your professional and personal communications effortlessly. Keep your work calls and messages on one number while maintaining your private life on another. This clean division helps you stay organized, set boundaries, and manage your time more effectively — especially if you're self-employed, freelance, or run a side business.

Protect your privacy and security online. When selling goods, connecting with buyers, or engaging with unfamiliar contacts, use your Onoff number instead of sharing your personal digits. Your safety is the priority. You'll communicate with confidence knowing your real identity stays protected. Plus, carrying just one phone means less weight in your pocket and zero hassle switching between devices.

Enjoy true flexibility. Use your Onoff number from any smartphone, tablet, or web browser — just like your email. Whether you're at your desk or on the move, your second number follows you everywhere. Need to port an existing number? You can bring it into the app and keep using it seamlessly. With numbers available from more than 30 countries, global communication is within reach.

Unlimited calls and SMS keep you connected without worrying about usage caps. Integrated visual voicemail and voice messages ensure you never miss important communications. All your contacts synchronize across devices, so your network stays unified and accessible. The app works with all SIM cards, automatically routing calls through the best available network for crystal-clear quality.

Make affordable international calls with prepaid credits. Unlimited calling covers most of Europe, while calls outside Europe use your credit balance — rates are transparent and competitive. Whether you're building a business, protecting your identity, or simply staying in touch with people worldwide, Onoff adapts to your needs.

Subscription plans are flexible: choose 1, 3, or 12-month terms at prices tailored to your country and selected features. Manage everything directly in the app, and cancel automatic renewal anytime through your account settings. Onoff brings the simplicity and versatility you deserve — multiple numbers, one app, infinite possibilities.
