What is this site? Airla-eSIM Hub is an independent informational resource about Airalo eSIM services. We explain how eSIM technology works, compare available plans, and help UK travellers choose the right data package for their destination. We do not sell eSIMs directly — all purchases are made through the official Airalo platform.
This site is structured to help you make a confident, well-informed decision about eSIM data plans. Follow the path below or jump directly to the section most relevant to you:

An eSIM (embedded SIM) is a digital SIM card built directly into your device. Unlike a physical SIM card, an eSIM can be programmed remotely, allowing you to switch carriers and activate data plans without inserting any hardware. This makes it ideal for international travel — you can purchase and activate a local data plan before you even board your flight.

Yes. Airalo eSIM plans are data-only. Your physical UK SIM card remains active in your device's primary SIM slot, so you can still receive calls and texts on your UK number. The eSIM handles data separately.
Activation typically takes 2–5 minutes after purchase. You receive a QR code via email and the Airalo app, which you scan in your device settings. See our step-by-step process guide for full instructions.
When your data allowance is exhausted, the eSIM plan stops providing data. You can purchase a top-up or a new plan through the Airalo app. Plans do not auto-renew.
