What is an eSIM? How it works and how to set one up
An eSIM does the same job as a SIM card, without the card. Here is how it works and what to check before you switch.
eSIM vs physical SIM
- Nothing to lose or damage: there is no card to fall out or break.
- Quick to switch: you can activate a new plan in minutes without visiting a shop, if your network allows it.
- Several plans on one phone: most phones can store multiple eSIMs, though usually only one or two are active at a time.
- Harder to move between phones: you transfer it through settings or your network rather than swapping a card.

Frequently asked questions
Can I use a physical SIM and an eSIM at the same time?
Yes, on most dual-SIM phones. You can use one line for calls and another for data, for example your home number plus a travel data plan.

Contact your mobile network. They can disable the lost eSIM and issue a new one to your replacement phone, usually after checking your identity.
Do all networks support eSIM?
No. Most large networks do, but support varies by country and plan. Check with your network before switching.
