eSIM Not Working? 7 Quick Fixes (ICCID, Compatibility Checks & Activation Guide)
If your eSIM shows No Service, won’t connect, or says Activation Failed, don’t panic (and don’t delete it yet). Most issues can be fixed in minutes with a simple checklist: compatibility → order email → ICCID → mobile data switch → data roaming / APN → airplane mode + reboot → support.
Do these 3 things first (they solve or identify the cause in most cases):
1) Confirm your phone supports eSIM (check EID / MEID or “Add eSIM”)
2) Open your order email (it contains install details and key identifiers)
3) Find your ICCID and share it with support — it lets us verify activation status quickly
What “eSIM Not Working” Usually Means
Most users describe “eSIM not working” in one of these ways:
- No Service / No Signal after switching to the eSIM
- No Internet even though signal bars appear
- Activation Failed or stuck on “Activating…”
- eSIM is installed, but your phone still uses the physical SIM for mobile data
Pro tip: Change one setting at a time, then wait 60–120 seconds before moving to the next step.
Step 1) Confirm Your Phone Supports eSIM (EID / EID Check)
Many “eSIM not working” cases are actually compatibility issues: your model (or regional variant) may not support eSIM, or eSIM is disabled by carrier policies. Verify compatibility first — it saves the most time.
Method A: Dial *#06# and look for EID
If you see EID (often under IMEI), your device is more likely to support eSIM.
Method B: Find “Add eSIM” in Settings
- iPhone: Settings → Cellular / Mobile Data → Add eSIM (or “Add Cellular Plan”)
- Android: Settings → Network & Internet / SIMs → Add eSIM (wording varies)
Step 2) Find Your Order Email (Install Details & Key Identifiers)
After purchasing an eSIM, you typically receive an email containing: QR code, install details, plan information, and important identifiers. This email is your fastest path to activation and support.
1) Star or save the email
2) Scroll to find ICCID — sharing it makes support much faster
Search your inbox for: “eSIM”, “QR code”, “ICCID”, “activation”, “install”, or “order”. Also check Promotions / Spam.
Step 3) Find ICCID (The #1 Identifier Support Needs)
ICCID is the unique identifier for your eSIM profile. When someone says “my eSIM has no service,” ICCID is the fastest way to verify the exact plan and activation status. It helps confirm whether the eSIM is activated, attached correctly, and provisioned for the right network.
“My eSIM has no service / no internet. My ICCID is: XXXXXXXXXXXXXXX. My phone model is ____. I’m currently in country/city.”
ICCID = eSIM profile ID • EID/IMEI = device identifiers (help confirm eSIM-capable devices).
In practice: ICCID is the most useful for support and plan verification.
Step 4) Most Common Fix: Switch Mobile Data to the eSIM
Many “eSIM not working” cases happen because your phone is still using your physical SIM for mobile data. You may have installed the eSIM correctly, but data is routed through the wrong line.
- Open Settings → Cellular / Mobile Network.
- Under “Mobile Data”, select your installed eSIM.
- Wait 1–3 minutes for the network to re-register.
Step 5) Check Data Roaming & APN (Many Plans Require This)
If you switched mobile data to the eSIM and it still won’t connect, the next common causes are: data roaming is off when it needs to be on, or APN is missing/incorrect (when the plan requires it).
Go to your eSIM line settings → find “Data Roaming” → enable it if your plan instructions require roaming ON. (Many travel eSIMs need roaming enabled to connect.)
Some plans provide a specific APN value. If your email/support instructions mention APN, enter it exactly as provided.
If you were not given an APN value, don’t guess — incorrect APN can break an otherwise working connection.
- Signal bars but no internet: check mobile data line + roaming + APN
- Stuck on “Activating…”: Step 6 (airplane mode / reboot) often helps
- Activation failed: Step 7 + support with ICCID
Step 6) 30-Second Fix: Airplane Mode + Reboot
This is one of the highest-success quick fixes for: eSIM not connecting, no service, and no internet. It forces the phone to re-register on the network.
- Turn Airplane Mode ON → wait 10 seconds → turn it OFF.
- Reboot your phone.
- Re-check: mobile data is set to eSIM, and data roaming is set as required.
Step 7) Re-Activate Properly (Video + Checklist)
If you’re not sure which step you missed, the fastest way is to follow the activation flow end-to-end. Below is the English activation tutorial video. After watching, if you still have issues, contact support with your ICCID.
On iPhone: Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings.
Then re-check: eSIM mobile data selection, data roaming, and APN (if required).

FAQ | eSIM Not Working / No Service / Activation Failed
Q1: What’s the most common reason an eSIM shows “No Service”?
The most common causes are: mobile data is not switched to the eSIM, data roaming is off when the plan requires it, or the device doesn’t support eSIM (EID/MEID / “Add eSIM” is missing). Start with Step 1 and Step 4 for the fastest fix.
Q2: Where do I find ICCID, and why does support ask for it?
ICCID is usually in your order email (and sometimes inside device SIM info). Support uses ICCID to verify the exact eSIM profile, plan, and activation status — it’s the fastest way to diagnose “eSIM not working.”
Q3: I have signal bars but no internet — what should I check?
First, confirm mobile data is set to the eSIM. Next, check data roaming (many travel eSIMs require roaming ON) and APN (only if your instructions provide an APN value).
Q4: Should I delete and reinstall my eSIM?
Not immediately. Many issues are fixed by switching mobile data, enabling roaming, toggling airplane mode, or rebooting. Only delete/reinstall if support confirms it’s safe and your plan allows re-downloads.
Q5: Can I install an eSIM before traveling? Will it consume data?
In most cases, you can install the eSIM on Wi-Fi before your trip. To avoid using data early, keep mobile data on your original SIM until you arrive, then switch mobile data to the eSIM.
Q6: What if my eSIM says “Activation Failed”?
Try Step 6 (airplane mode + reboot) and Step 7 (follow the activation video). If it still fails, contact eSIMKitStore support with your ICCID and phone model so we can verify activation status and guide the fix.
