What is an EID, and when do you need it for an eSIM?

An EID is a 32-digit number identifying the built-in hardware that stores your eSIMs. The other long numbers have different uses: an IMEI identifies the phone’s mobile equipment, while an ICCID identifies one SIM or installed eSIM. If support asks for an EID, copy the field labelled EID rather than whichever number is easiest to find.

If your question is “Will this phone work?”, start with the model number, sales region and carrier-lock status in our compatibility checker. Finding an EID doesn’t answer all three, and it says nothing about the countries or radio bands supported by a selected travel offer.

On iPhone, open Settings > General > About and find the item labelled EID. On Android, start with Settings > About phone and search Settings for EID if it isn’t visible; the route varies by model and software.

If the label isn’t there, tell support which model and software you have rather than substituting the IMEI or sending a screenshot of the entire About page.

For an initial SIM Shop enquiry, send the order number, exact model and error in text. Keep a cropped, redacted screenshot ready only if support asks for one, hiding the QR, activation details and full device identifiers.

If we specifically need an EID to investigate the order, use the private support route we provide. Keep it out of public comments, shared travel groups and social posts. You can get help without turning the phone’s identity page into holiday reading for everyone else.
