An eSIM is a digital SIM card permanently embedded within your device's hardware. Rather than inserting a physical plastic card, you download carrier profiles over the internet. Multiple profiles may be stored simultaneously, with instant switching between them.
iPhone XS and all subsequent models (2018 onwards), Samsung Galaxy S20 and later (2020 onwards), Google Pixel 3 and later (2018 onwards), and many other contemporary smartphones. Your device must also be carrier-unlocked. Consult our device registry for the complete list.
Indeed. This is among the most compelling advantages of eSIM technology. Your home SIM remains active for calls and messages while the eSIM handles data. Configure the preferred data line in your device settings. You enjoy the full capabilities of both simultaneously.
Upon purchasing a plan, you receive a QR code by email. On iPhone: Settings → Cellular → Add Cellular Plan → scan the QR code. On Android: Settings → Network → SIM Manager → Add eSIM → scan the QR code. The process requires approximately five minutes and should be completed on a reliable Wi-Fi connection before departure.
Most European eSIM plans utilise 4G LTE networks, providing 20–100 Mbps in urban environments. This is more than sufficient for video conferencing (3 Mbps required), HD streaming (5 Mbps required), and all general connectivity needs. Select providers offer 5G access in major cities.
eSIM is, in fact, more secure than a traditional physical SIM. The chip is permanently integrated into the device and cannot be removed or stolen. Profiles are cryptographically bound to the specific device EID, preventing unauthorised transfer. The GSMA mandates rigorous security standards for all certified implementations.
Service either ceases or speeds are reduced to minimal levels (128–256 kbps). Most providers offer top-up options through their application, without requiring a new QR code. We recommend monitoring your usage through your provider's app throughout your journey.
eSIM profiles are cryptographically bound to the specific device EID and cannot be directly transferred. Contact your provider to request a new activation code for your new device. Many providers accommodate this at no charge; others apply a modest fee. We recommend preserving your original QR code as a precaution.
