One eSIM for 200+ Global Destinations
Ubigi’s single QR code installation simplifies international travel. Once installed, the same eSIM works in nearly 200 countries and regions — no need to buy a new plan or scan new QR codes when you cross borders. This is ideal for travelers on multi-country trips or remote professionals relocating frequently.
Plan Starts Automatically Upon Arrival
Unlike many eSIM providers, Ubigi’s data plan doesn’t start counting down the moment you buy it. Instead, the plan activates only when you arrive at your destination and connect to a local network. This means:
- No wasted days before your trip
- You can buy a plan up to 6 months in advance
- You’re instantly connected once you land
Top-Up Without Internet
Ubigi provides a free-access function to its app, even if you have no mobile data or Wi-Fi. This means you can top-up from anywhere, even if you’re disconnected. As long as your Ubigi eSIM is installed, you can access the app to recharge — ideal during emergencies or long travel days.
Free 5G in Over 60 Countries
Ubigi delivers fast, stable 5G connectivity at no additional cost in more than 60 countries. Whether you’re streaming, video calling, or working on the go, Ubigi offers consistent performance — with no hidden fees or downgrades for 5G usage.
Tethering Allowed on All Plans
Unlike some competitors who restrict personal hotspot use, Ubigi allows full tethering functionality on all plans. You can connect your laptop, tablet, or friend’s device with ease — making it perfect for business trips or families traveling together.
Affordable Local-Rate Plans
Ubigi offers competitively priced data packages that often match or beat local SIM rates in top destinations. Choose from:
- One-time plans (great for short trips)
- Recurring plans (ideal for digital nomads or business travelers)
- Unlimited plans (available in 50+ countries)
Flexible Packages: From 500MB to Unlimited
Superior Connectivity with Transatel & NTT
Ubigi is a Full MVNO, not just a reseller. It connects through Transatel and its parent company, NTT Group — Japan’s largest telco. This infrastructure provides better signal reliability and fewer dead zones, thanks to regional partnerships with multiple carriers in each country.
Trusted by Automotive Giants Like BMW
Ubigi’s technology has been integrated into vehicles from leading car manufacturers such as BMW. While this feature is separate from travel eSIM use, it’s a strong endorsement of Ubigi’s tech reliability and network trustworthiness.
Biometric Login for Extra Security
Ubigi’s apps (available for both iOS and Android) support Face ID and fingerprint login, making your account more secure and faster to access. This ensures quick top-ups and better control over your data usage while you travel.
Home IP Feature for Streaming & Apps
For American and French users, Ubigi now offers a Home IP option — meaning you can appear as if you’re browsing from your home country while abroad. This helps access content, services, and apps that are restricted to specific countries.
Multilingual App & Global Support
Ubigi supports travelers worldwide with:
- Website available in 8 languages
- App in over 10 languages
- 24/7 multilingual chatbot
- Support via app and online documents
- Multiple payment methods including Apple Pay, Google Pay, and credit cards
