What Is EID? Why It Matters for eSIM (Check in 1s with *#06#)
If you’re searching for “what is EID”, “IMEI vs EID”, or “can I use eSIM without EID”, this post explains it in the simplest way: why EID matters for eSIM, how to check with *#06#, and what to do next to set up your eSIM.
1) Do this first: Check if your phone has an EID with *#06#
Before buying an eSIM, the most important step is not choosing a plan — it’s confirming your phone truly supports eSIM. The fastest method: open your dialer and enter *#06#.
❌ Case A: IMEI only, no EID (usually cannot use eSIM)
✅ Case B: EID is shown (usually OK to buy/use eSIM)

2) IMEI vs EID: What’s the difference? Why does eSIM care about EID?
When people dial *#06#, they often notice IMEI first. But for eSIM, the key signal is whether your screen also shows an EID. This table makes it clear:
| Item | IMEI | EID |
|---|---|---|
| What it is | A common device identifier (most phones have it) | The unique identifier of the eSIM chip (key for eSIM) |
| Shown in *#06#? | Most phones show it | eSIM-capable devices usually show it (display varies by brand/model) |
| Meaning for eSIM | Useful device info, but it does not equal eSIM support | Seeing EID usually indicates eSIM capability (confirm via device + list) |
| How to use this | IMEI is normal to see | EID shown → usually safe to buy eSIM; not shown → check list + see if you can add eSIM |
3) If you have EID, what’s next? (From plan selection to getting online)
If you’ve confirmed your phone has an EID (or your model is listed as compatible), follow this order and you’ll be fine.
STEP 1｜Choose your country + plan (days + data GB)
Decide your destination and trip length, then pick a reasonable amount of data (GB). Typical travel usage: maps, searching info, messaging, ride-hailing, itinerary planning.
STEP 2｜Enter your email at checkout and wait for the QR code
- Use a correct email: your QR code and installation guide will be sent there.
- Usually within 24 hours: you’ll receive an email with your QR code (subject to actual delivery).
STEP 3｜When is the safest time to scan/install?
Recommended: 1 day before departure, on stable Wi-Fi.

STEP 4｜After arrival: turn on “Data Roaming” and wait for auto connection
- Switch mobile data to your eSIM line
- Turn on “Data Roaming” (depending on your plan)
- In most cases, you’ll connect within 30 minutes
• Toggle Airplane Mode once
• Restart your phone
• Re-check Data Roaming is ON and mobile data is set to the eSIM line
One-line summary: To use eSIM, first check if your phone has an EID (or supports eSIM)
Check EID with *#06#, confirm your model in the compatibility list, then follow: “Choose plan → Receive QR code → Scan before departure → Turn on roaming after arrival”.

FAQ｜EID / IMEI / eSIM
Q1: What is EID?
EID is the unique identifier of the eSIM chip. For beginners, you don’t need the deep technical details — just remember: seeing EID on *#06# usually means your phone is eSIM-capable (confirm with the compatibility list and your device settings).
Q2: If I only see IMEI but no EID, does that mean I can’t use eSIM?
In most cases, yes — it usually means your phone doesn’t support eSIM or can’t use it. To be safe, double-check the compatibility list and see if your phone settings allow you to “Add eSIM”.
Q3: I don’t see EID in *#06#, but I can “Add eSIM” in settings — what should I do?
Some brands/models show different fields. If your phone can add an eSIM and your model is listed as compatible, you may still be able to use eSIM normally. Final rule: compatibility list + your device can add eSIM.
Q4: When should I scan the QR code?
Ideally 1 day before departure on stable Wi-Fi. Too early and you may forget; too late and airport/hotel Wi-Fi can fail. Follow the setup guide.
Q5: I can’t connect after arrival — what now?
First confirm mobile data is set to the eSIM line and Data Roaming is enabled (if required). Then toggle Airplane Mode or restart your phone. If it still doesn’t work, revisit the product page rules and follow the setup checklist step-by-step.
