Portable hotspot devices connecting multiple devices simultaneously. Useful for groups and multi-device travelers.
Using your home carrier's network abroad. Convenient but often expensive outside regulated zones.
The European travel connectivity market has undergone profound change since 2020. eSIM adoption has accelerated dramatically, driven by device ecosystem maturation and growing traveler awareness of roaming costs.
Our research tracks these trends across the continent, examining how travelers approach data access and where the most significant information gaps remain.
Quick answers to the questions our readers ask most often.
An eSIM (embedded SIM) is a digital SIM card built into your device that can be programmed remotely with a carrier profile. Unlike a physical SIM, it requires no physical handling — you download a carrier's profile via QR code or app, making it ideal for international travelers who want to activate connectivity before departure.
Most flagship smartphones released since 2018–2020 support eSIM. Apple iPhone XS and later, Google Pixel 2 and later, Samsung Galaxy S20 and later flagships, and many mid-range Android devices all include eSIM support. Check your device settings for an EID number to confirm eSIM hardware support.
Yes — most modern smartphones support dual-SIM operation with one physical SIM and one eSIM active simultaneously. This lets you keep your home number on one line while using a travel eSIM for data. Configuration varies by device model.
