Where it works
Coverage spans 197 countries through single country options and regional options. Single country choices focus on frequently visited spots such as the United Kingdom, the United Arab Emirates and Türkiye. Regional choices link areas such as Lisbon to Helsinki, Tokyo to Bangkok, six Gulf states together, Cairo to Cape Town, and a group of 20 destinations. One eSIM can cover a whole journey including unplanned layovers. Service links to fast local 4G and 5G networks after arrival, with installation completed at home before departure.
A data line beside your home SIM
The travel line runs alongside the SIM that already sits in the handset, so one phone can hold two lines at once. It carries mobile data only, which leaves calls and texts on the home number where they normally arrive. Once the trip begins, the line connects to local 4G and 5G networks without a card change. A hotspot option lets the same connection be shared with a laptop or tablet for companions travelling together. Because the line is data only, the split between the two numbers is easy to keep in mind.

Frequently asked questions
What is Strong eSIM?+
Strong eSIM is a travel eSIM that provides mobile data abroad without a plastic card. It lives beside a current SIM and connects to local networks after arrival. It is built for trips where maps, rides and messaging matter.
Where does Strong eSIM work?+
Service reaches 197 countries through single country and regional plans. Regional options join routes across Europe, Asia, the Gulf states and Africa. One eSIM can stay active across a whole itinerary, including layovers.
How does activation work?+
Choose a destination and data amount, then receive a QR code by email. One scan installs the eSIM beside the normal SIM before departure. Mobile data starts when the destination is reached on a local network.
Can I keep my normal number while using it?+
The normal SIM remains in place for its usual number during travel. Calls and texts continue on that number while Strong eSIM supplies internet access. Both lines operate together without swapping cards or visiting a shop.
What happens if data runs low during a trip?+
More data can be added from the phone during the trip when the balance drops. Installation takes about a minute and support is available around the clock. Setup is completed at home to avoid airport configuration delays.
Can the travel line be shared with a laptop as well as a phone?+
Yes, the connection can be shared with a laptop or tablet through a hotspot. That makes it handy for a shared workspace in a hotel room or during a long transfer. Sharing draws on the same mobile data as the phone, so heavy use on a laptop uses the same data pool.
Who suits a data only travel line?+
People who already keep a number for calls and texts are a natural fit, since the travel line leaves that number alone. Trips where maps, messaging and online bookings matter also suit this setup. Splitting the jobs between two lines keeps the arrangement simple to understand.
