Airtel eSIM not working after transferring it to a new phone in 2026; you are not alone. After moving an eSIM from one device to another, it is possible to experience problems such as no network, emergency calls only, mobile data not working, inability to make calls, or the eSIM showing as inactive.
In most cases, the problem is related to the eSIM activation process, network registration, device settings, or the transfer not completing correctly. Sometimes the new phone may show the Airtel eSIM profile, but the SIM is still not fully activated on the network.
The good news is that many of these problems can be fixed without immediately replacing your number. In this guide, we will explain the common reasons why an Airtel eSIM stops working after transfer and provide practical steps to check your phone, network settings, mobile data, and eSIM activation status. We will also explain what to do if the basic troubleshooting steps do not work.
Transferring an Airtel eSIM from one phone to another is fundamentally different from initial eSIM activation — and the issues that arise after transfer are equally distinct. Unlike physical SIM cards that simply move between devices, eSIM transfer requires deactivating the profile on the old device and reactivating it on the new one through Airtel’s eSIM infrastructure. Understanding this process — and what can go wrong — helps resolve transfer issues quickly.
This guide covers every Airtel eSIM transfer issue in 2026 — from iPhone-to-iPhone migration to Android switching, old device conflicts to new device registration problems.

Understanding Airtel eSIM Transfer
Why eSIM Transfer is Different from Physical SIM
Physical SIM transfer:
Remove from old phone → insert in new phone → works immediately.
Airtel eSIM transfer:
- Delete eSIM from old device (deactivate profile)
- Request new eSIM from Airtel
- Download and activate on new device
- New activation process required
Key point: Airtel eSIM cannot be “moved” directly — it must be deactivated and re-provisioned.
Common Transfer Scenarios
| Scenario | Transfer Method |
|---|---|
| iPhone → New iPhone | iPhone Quick Start OR manual re-activation |
| iPhone → Android | Manual re-activation required |
| Android → New Android | Manual re-activation required |
| Android → iPhone | Manual re-activation required |
| Damaged phone → New phone | Contact Airtel 121 |
Before Transferring Airtel eSIM — Checklist
Complete BEFORE switching phones:
✅ Note your Airtel mobile number
✅ Note the EID of the new device (Settings → About → EID)
✅ Download the Airtel Thanks app on the new device
✅ Ensure the new device is eSIM compatible
✅ Keep the old device charged and accessible
✅ Stable internet connection on both devices
✅ Aadhaar/OTP access for KYC verification
How to Correctly Transfer Airtel eSIM
Step 1 — Delete eSIM from Old Device
iPhone:
Settings → Cellular → tap Airtel eSIM plan → Remove Cellular Plan → confirm.
Android:
Settings → Connections → SIM card manager → Airtel eSIM → Delete eSIM → Confirm.
Why essential:
Airtel only allows one active eSIM per number — the old profile must be deactivated before the new device activation works.
Step 2 — Request New eSIM on New Device
Airtel Thanks app (new device):
- Install Airtel Thanks on the new phone
- Account → SIM Services → Switch to eSIM
- Enter Airtel mobile number
- Verify OTP (sent to registered number — may need old device)
- New QR code generated
Step 3 — Activate on New Device
iPhone:
Settings → Cellular → Add Cellular Plan → scan QR → confirm → eSIM downloads.
Android:
Settings → Connections → SIM card manager → Add mobile plan → scan QR → confirm.
Step 4 — Configure New Device
iPhone:
Settings → Cellular → set Airtel eSIM as primary/secondary → configure data and voice lines.
Android:
Settings → Connections → SIM card manager → set Airtel eSIM for calls, data, SMS.
Issue 1 — Airtel eSIM Not Activating on New Device
Symptoms
- QR scanned successfully
- “Activation Failed” error on new device
- Profile downloads but no signal
Cause
Old device eSIM profile still active — Airtel blocking duplicate activation.
Fix 1 — Ensure Old Device eSIM Deleted
Verify the old device eSIM is removed:
Old iPhone: Settings → Cellular → Airtel plan should NOT appear.
Old Android: Settings → SIM manager → no Airtel eSIM visible.
If still present → delete → retry new device activation.
Fix 2 — Request Fresh QR Code
QR code validity: 24–72 hours — an expired QR causes activation failure.
Get fresh QR:
Airtel Thanks → Switch to eSIM → new QR generated → scan immediately on new device.
Fix 3 — Call Airtel 121
Backend profile conflict:
Sometimes Airtel backend still shows the old device as active despite local deletion.
Fix:
- Call 121 → report eSIM transfer issue
- Provide: mobile number + old device IMEI + new device EID
- Airtel backend team deactivates old profile → clears for new device
- Retry activation on new device
Issue 2 — OTP Not Received During Transfer
Symptoms
- Transfer process requires OTP
- OTP not arriving on old/new device
- Transfer stuck at verification step
Cause
OTP sent to Airtel number — if the eSIM is deleted from the old device before the OTP is received → no way to receive the OTP.
Fix — Correct Transfer Sequence
Never delete the old eSIM before receiving the OTP:
Correct sequence:
- Start transfer on new device (Airtel Thanks)
- OTP sent to your number
- Receive OTP on OLD device (still active)
- Enter OTP on new device
- New QR generated
- NOW delete the old device eSIM
- Scan QR on new device → activate
Wrong sequence (causes OTP issue):
❌ Delete old eSIM first → start transfer → OTP has nowhere to go.
Fix if Already Deleted Old eSIM
OTP delivery options without active eSIM:
- Call Airtel 121 → request voice OTP → delivered to registered alternate number
- Visit Airtel store → staff verifies identity → manual transfer authorization
- Email OTP if registered email exists → check Airtel Thanks account
Issue 3 — New Device Shows “No Service” After Transfer
Symptoms
- Transfer completed
- New device shows Airtel eSIM in settings
- No signal or “No Service” showing
Fix 1 — Wait for Network Registration
Post-transfer registration takes time:
- 5–15 minutes: Initial signal
- 15–30 minutes: Stable connection
- Up to 1 hour: Complete service restoration
Do not troubleshoot within the first 30 minutes.
Fix 2 — Toggle Airplane Mode
New device → Airplane Mode ON → 30 seconds → OFF → forces a network scan.
Fix 3 — Restart New Device
Complete restart after eSIM transfer → allows fresh network registration.
Fix 4 — Manual Network Selection
Settings → Cellular/Mobile networks → Network operators → Manual → select Airtel → switch back to Automatic.
Issue 4 — Old Device Still Working After Transfer
Symptoms
- eSIM deleted from old device
- But the old device is still receiving calls
- Both devices seemingly active
Cause
Network-level delay — Airtel backend may take time to deactivate the old profile completely.
Fix
This resolves automatically within 2–4 hours:
Airtel backend deactivation propagates → old device loses signal → new device becomes the sole active device.
Speed up:
Call 121 → request immediate old profile deactivation → backend team prioritizes.
Issue 5 — iPhone Quick Start eSIM Transfer Issues
iPhone Quick Start:
iOS 16+ allows eSIM transfer between iPhones during Quick Start setup.
When Quick Start eSIM Transfer Fails
Symptoms:
- Quick Start completes
- New iPhone shows eSIM but no Airtel signal
- “eSIM transfer not supported by carrier” error
Fix 1 — Carrier Support Check
Airtel Quick Start eSIM transfer:
Not all carriers support iOS Quick Start eSIM transfer — Airtel support varies by circle and iOS version.
If not supported: Use the manual transfer method instead (Airtel Thanks app QR).
Fix 2 — iOS Version Requirement
Quick Start eSIM transfer requires:
- Both iPhones on iOS 16+
- Both iPhones within Bluetooth range during transfer
- Both connected to the internet
Fix 3 — Manual Transfer Fallback
If Quick Start fails for Airtel:
- Complete iPhone Quick Start (apps, settings transfer) — skip eSIM
- After setup complete → Airtel Thanks app → Switch to eSIM → manual QR activation
Issue 6 — Airtel eSIM Transfer from Damaged Phone
Scenario
Old phone screen broken/water damaged → cannot delete eSIM normally.
Fix 1 — Remote Deactivation via Airtel
Call 121:
“My old phone is damaged — need to transfer Airtel eSIM to new device”
Provide: Mobile number + old device IMEI (check box/purchase receipt) + new device EID
Airtel remotely deactivates the old profile → new device activation proceeds.
Fix 2 — Airtel Store Visit
Physical store visit → ID verification → Airtel staff remotely deactivates the old profile → new QR issued for the new device.
Documents needed:
- Aadhaar card
- New device (EID required)
- Proof of old device ownership (if possible)
Fix 3 — If Old Phone Partially Working
Broken screen but phone boots:
- Use voice commands (Hey Siri/Google Assistant)
- “Open Settings” → navigate to eSIM deletion by touch
- Connect to external display via USB-C (some Android devices)
- Delete eSIM remotely → enables new device transfer
Issue 7 — Data Works But Calls Not After Transfer
Symptoms
- New device has Airtel signal
- Mobile data working
- Voice calls not connecting
Fix 1 — Default Voice Line Selection
iPhone:
Settings → Cellular → Default Voice Line → select Airtel eSIM (not secondary SIM).
Android:
Settings → Connections → SIM card manager → Calls → select Airtel eSIM.
Fix 2 — Re-enable VoLTE After Transfer
Transfer sometimes resets the VoLTE setting:
iPhone:
Settings → Cellular → Cellular Data Options → Enable LTE → Voice & Data.
Samsung:
Settings → Connections → SIM manager → Airtel eSIM → VoLTE calls → ON.
Device-Specific Transfer Issues
iPhone to iPhone Transfer
Easiest transfer — two methods:
Method 1 — Quick Start:
Place new iPhone near old iPhone → Quick Start → follow prompts → eSIM transfer option appears → approve → may take 5–10 minutes.
Method 2 — Manual:
Old iPhone: delete eSIM → Airtel Thanks on new iPhone → QR scan → activate.
iPhone to iPhone success rate: High — iOS Quick Start is well-integrated with Airtel.
Android to iPhone Transfer
Most common transfer issue:
- Delete Airtel eSIM from Android
- Install Airtel Thanks on iPhone
- Switch to eSIM → verify OTP
- QR scan in iPhone Settings
- Configure as primary line
Common issue: Airtel Thanks Android account → log in to the same account on iPhone → verify the Airtel number matches.
iPhone to Android Transfer
- Delete from iPhone: Settings → Cellular → Remove Cellular Plan
- Android: Airtel Thanks → Switch to eSIM
- QR scan in Android SIM manager
- Configure data/calls preferences
Android to Android Transfer
Same-brand (Samsung to Samsung):
Galaxy SmartSwitch may offer an eSIM transfer option → follow prompts → if it fails → manual Airtel Thanks method.
Different brand (Samsung to Pixel):
Manual transfer only → delete old → Airtel Thanks new device → QR scan.

Frequently Asked Questions
How do I transfer Airtel eSIM to a new phone in 2026?
Delete Airtel eSIM from old device (Settings → Cellular → Remove Cellular Plan on iPhone, or SIM manager → Delete on Android) → install Airtel Thanks on new phone → Switch to eSIM → verify OTP → scan QR code → eSIM activates on new device in 10–20 minutes. Never delete the old eSIM before receiving the OTP — keep the old device active until OTP verification is complete on the new device.
Why is my Airtel eSIM not working after phone transfer?
Most common cause: Old device eSIM not properly deleted → Airtel blocks duplicate activation. Fix: Verify the old device eSIM is deleted → call Airtel 121 if the backend still shows the old device as active → request manual deactivation → retry new device activation with a fresh QR code from the Airtel Thanks app.
Can I transfer Airtel eSIM without deleting from old phone?
No — Airtel only allows one active eSIM per number. Attempting new device activation without deleting the old profile results in activation failure. Delete the old device profile first → then activate the new device. Exception: damaged/inaccessible old phone → call Airtel 121 → remote deactivation → new device activation.
My old phone is broken — how do I transfer Airtel eSIM?
Call Airtel 121 → explain damaged device situation → provide mobile number + old IMEI + new device EID → Airtel remotely deactivates old profile → issues new QR for new device. Alternatively, visit an Airtel store with ID proof and the new device → staff handles remote deactivation and new activation. Keep purchase receipt/box for old IMEI if screen inaccessible.
Airtel eSIM transferred but no signal on new phone — how long to wait?
Wait a minimum of 30 minutes after successful eSIM download before troubleshooting — network registration takes time. If no signal after 1 hour: toggle Airplane Mode, restart device, manually select Airtel network. If no signal after 4 hours: call Airtel 121 — backend issue requiring manual resolution.
Conclusion
Airtel eSIM transfer issues in 2026 are primarily caused by incorrect transfer sequence — specifically attempting new device activation before properly deactivating the old device profile.
An Airtel eSIM not working after transfer can be frustrating, especially when your old phone no longer has service, and the new phone is unable to connect to the Airtel network. However, the issue is often caused by an incomplete activation, incorrect network settings, temporary network registration problems, or an unsuccessful eSIM transfer.
Start with the simple solutions first: restart your phone, check that the Airtel eSIM is enabled, confirm mobile network settings, and make sure your device is connected to a supported network. If the eSIM still shows no service after completing these checks, avoid repeatedly deleting and reinstalling the eSIM profile. Instead, contact Airtel support or visit an Airtel store for assistance with reactivation or a replacement eSIM.
Key transfer rules:
- Never delete the old eSIM before OTP verification — receive the OTP on the old device first
- Delete the old profile completely before new device activation
- Wait 30 minutes after transfer before troubleshooting
- Call 121 for a damaged phone — remote deactivation available
- Fresh QR code if activation fails — old QR may have expired
Correct transfer sequence:
Old device active → Start transfer on new device → Receive OTP on old device → Enter OTP → Get new QR → Delete old device eSIM → Scan QR on new device → Configure → Done.
Following this sequence prevents 90% of Airtel eSIM transfer issues.
