How to find your phone's EID and IMEI before buying an eSIM
An EID identifies the eSIM hardware in a device; an IMEI identifies a mobile device or line. A seller may request one of them to check or activate service. Find the number in phone settings, then confirm the exact model supports eSIM and is unlocked.
Which number do you need?
EID
A long identifier for the embedded SIM. Its presence is a useful clue that the device has eSIM hardware.
IMEI
An identifier for cellular hardware. Dual-SIM phones may show more than one IMEI.
Model and lock status
Neither identifier alone proves a travel eSIM will work with a different carrier.
Find the identifiers in phone settings
On iPhone, open Settings, General, About and scroll to EID and IMEI. On a Pixel, open Settings, About phone and look for SIM status or device identifiers; the exact labels can change with Android version. On Galaxy, open Settings, About phone, then Status information or SIM manager as appropriate for the model. Copy the number from the settings screen instead of retyping a long string. Keep a private screenshot only if the provider needs you to refer back to it during activation.
If you cannot find an EID, check the manufacturer's specification for your exact model and purchase region. Some models have regional eSIM differences, and a software menu can vary by carrier. Google's Pixel eSIM instructions and Samsung's Galaxy SIM guidance are good starting points, but the device's own settings are the best evidence for the phone in your hand.
Check compatibility beyond the EID
A visible EID does not mean any eSIM from any provider can be installed. Check that the phone is carrier-unlocked, that the model supports eSIM in your market, and that the travel plan supports the destination. An IMEI check offered by a carrier may confirm one network's compatibility, but it does not guarantee coverage or unlock status elsewhere. Follow the unlocked-phone checklist before paying.
Some newer phones can store several eSIM profiles but use only a limited number of lines at one time. The number varies by model. If you already have work and personal lines, decide which one can be disabled while travelling. Read how many eSIMs your phone can use rather than assuming every stored profile can remain active.
| Item | Useful for | Does not establish |
|---|---|---|
| EID | Identifying the embedded SIM for some activations. | Carrier unlock, destination coverage or plan validity. |
| IMEI | Device or line checks requested by a carrier. | That an eSIM profile can be installed. |
| Exact model | Checking regional eSIM support and device instructions. | That the particular phone is unlocked. |
| Unlock status | Using another provider's service. | That the chosen destination has a working network. |
Give identifiers only to the party that needs them
An EID or IMEI is not a password, but it is a persistent device identifier. Send it through the provider's official checkout or support channel, and check the website address before submitting. If a form asks for an identifier you cannot find, ask why it is needed and whether the model name is sufficient for a compatibility check. Avoid posting screenshots of your About screen on forums or social media.
After activation, save the plan receipt and support reference separately from the public device information you might share for troubleshooting. If support asks for a screenshot, crop it to the relevant settings and remove unrelated identifiers. The next setup step is to install the QR code using the instructions for your phone and provider.
