What is an eSIM?

Stay connected with eSIM: here's how

An eSIM (Embedded SIM) is a digital SIM built directly into your device, so there's no physical SIM card to insert or replace.Activate it in one tap and your mobile plan is installed instantly or simply scan a QR code.

You can:

  • Install a plan in seconds
  • Keep your existing SIM active
  • Connect in 200+ destinations
  • Avoid roaming charges

Compatible with most modern smartphones, tablets, and smartwatches, eSIM is the easiest way to stay connected while travelling.

Can I use more than one eSIM?

Multiple plans on a single device

Purchased more than one eSIM? No problem. Each eSIM is managed independently, giving you complete flexibility throughout your journey. You can activate plans for different destinations whenever needed.

You can:

  • Install each eSIM whenever you need it
  • Monitor usage and data balance separately
  • Activate plans for different countries at different times
  • Cancel an individual eSIM without affecting the others

Perfect for multi-country trips, frequent travellers, or anyone planning several journeys in advance.
