What Is an eSIM?
An eSIM is a digital SIM built into your phone. It does the same job as a physical SIM, but you activate it through software, so there is no card to insert. Your number and plan stay the same when you convert.
Does Your Phone Support Airtel eSIM?
eSIM support depends on the exact model and sometimes the region it was sold in. Support is common on these phones:
- Apple: iPhone XS, XS Max, XR and newer models.
- Google: many Pixel phones from the Pixel 3 onward.
- Samsung and Motorola: many recent premium models.
Quick check: look for an EID number. On iPhone, go to Settings > General > About. On Android, try Settings > About Phone. If your phone shows an EID, it supports eSIM.
How to Activate Airtel eSIM by SMS

- Open your messages on your Airtel phone.
- Send eSIM <your email ID> to 121. Example: eSIM name@example.com.
- Confirm the request. You may be asked to reply with 1 within 60 seconds, or you may get a consent call.
- If asked, send your EID number as instructed in the SMS.
- Wait for the QR code to reach your email.
- On your phone, add a mobile plan or eSIM in Settings and scan the QR code.
- Wait for activation, then restart your phone if needed.
How to Activate Airtel eSIM in the Airtel Thanks App
You can also start in the app. Open Airtel Thanks, select your number, and look for the option to convert to eSIM under your SIM or account settings. The menu names can change between app versions.
Airtel eSIM Charges
Reports say Airtel doesn’t charge a separate eSIM fee, and your existing plan continues. It’s still worth confirming this with Airtel before you begin, as it can depend on your request.
Tips Before You Convert
- Use an email ID you can open right away.
- Stay on good Wi-Fi or mobile data while setting it up.
- Keep your physical SIM until the eSIM is working.
- Stay safe: never share your QR code, EID or OTP with anyone who calls you, even if they claim to be from Airtel.
- When changing phones, you will need a new eSIM, so plan ahead.
FAQs
What if I miss the confirmation call?
The request may be cancelled. Send the SMS again and keep your phone nearby.
Can I use an eSIM and a physical SIM together?
Yes, on most dual-SIM phones that support eSIM. You could keep your Airtel number on eSIM and use a second number on a physical SIM.
Will I lose my number or plan?
No. Converting changes the SIM type, not your number or plan.
Can I go back to a physical SIM?
Yes. You can request a replacement physical SIM from Airtel.
