eSIM in India 2026: Complete Guide for Jio, Airtel and Vi Users

An eSIM is a SIM card that is soldered into your phone instead of slotted into it. Everything a plastic SIM does, it does, except you activate it by scanning a QR code and you can hold several profiles on one chip. In India, Jio, Airtel and Vi all support it, and most phones sold above the budget tier now have the hardware.

The catch is that the process differs by operator, prepaid and postpaid work differently, and a failed activation can leave you without a working number for a day. This guide from TechLein covers the whole thing: which phones support it, exact activation steps for each operator, how to convert an existing number, and what to do when it goes wrong.

Key takeaways

• eSIM activation is free with all three Indian operators, but requires KYC just like a physical SIM.
• Your phone must be unlocked and your number must be in your own name.
• Do not factory reset or discard the old SIM until the eSIM is confirmed working.
• eSIM makes international roaming far cheaper, you can add a local travel plan without removing your Indian number.

What an eSIM actually is

The eSIM is an embedded chip that stores a downloadable SIM profile. Instead of a shopkeeper handing you plastic, your operator sends a profile that your phone downloads over Wi-Fi or mobile data.

Practical consequences: nothing to lose or damage, no tray to pry open, and the ability to store multiple profiles and switch between them in settings. Most phones let you keep several profiles saved but only one or two active at a time.

Which phones support eSIM in India

Support is now common but not universal, and it varies by market variant, an identical model sold abroad may differ.

• Apple: iPhone XS and later, including all current models. iPhones sold in India retain a physical tray alongside the eSIM.
• Samsung: Galaxy S20 series onward, most Z Fold and Z Flip models, and recent A-series devices.
• Google: Pixel 3 and later.
• OnePlus, Vivo, Oppo, Xiaomi, Motorola, Nothing: supported on many recent mid-range and flagship models, but check the specific variant.

The reliable check: open Settings and search for eSIM, or dial the EID lookup in your SIM settings. If your phone shows an EID number, it has an eSIM. If you are still shopping, add it to the list in our smartphone buying checklist.

Before you start

1. Confirm the connection is in your own name. Operators will not convert a number registered to someone else.
2. Keep an alternate phone or a Wi-Fi connection ready, you will need internet after the physical SIM stops working.
3. Note your EID and IMEI. Settings, About phone, or dial the standard IMEI code.
4. Charge the phone above 50 percent. An interrupted profile download is the main cause of failed activation.

How to get an eSIM: operator by operator

Jio

Send an SMS in the format GETESIM followed by your EID and IMEI to Jio’s eSIM number, or use the MyJio app’s eSIM section. Jio replies with a 19-digit eSIM profile ID, then a consent SMS you must reply to with a code. After confirmation, a QR code arrives by email or is pushed to the app. Scan it under Settings, Mobile Network, Add eSIM.

Airtel

Email eSIM from your registered address to Airtel’s eSIM address, or request it in the Airtel Thanks app. Airtel sends a consent SMS, you reply, then a QR code arrives by email. Scan it to install the profile.

Vi

Send an SMS reading eSIM followed by your registered email address to Vi’s eSIM number. After the consent exchange, the QR code is emailed to you. The Vi app offers the same route.

Across all three, expect the physical SIM to stop working within roughly two hours of the profile activating. That gap is normal, do not restart repeatedly during it.

Converting an existing number vs a new connection

If you are moving between operators rather than formats, that is a different process, see our step-by-step on porting your mobile number and do the port first, then convert to eSIM.

Using eSIM for international travel

This is the strongest argument for eSIM. Rather than paying Indian roaming rates or hunting for a SIM at an unfamiliar airport, you buy a travel eSIM online before departure, install the profile, and land with data already working. Your Indian number stays active for OTPs, which matters if you plan to use UPI abroad or receive banking messages.

Set the Indian profile to data off and the travel profile as your data line to avoid accidental roaming charges.

Common problems and fixes

QR code will not scan or says invalid

A profile can be installed only once. If you already scanned it, or reset the phone after installing, the operator must reissue it.

No network after activation

Restart once, then check that the eSIM line is enabled and set as the default for calls and data. Verify APN settings if data alone is failing.

Consent SMS never arrives

Confirm your registered email with the operator matches the one you are using. Mismatch is the most common cause.

Lost access after changing phones

An eSIM profile does not transfer with a backup. You must request a new profile from the operator for the new device. Plan the switch before wiping the old phone, and see our guide to selling an old phone safely.

eSIM and security

eSIM removes the physical-theft angle, someone cannot pop your SIM into another handset. It does not protect against operator-side social engineering, which is how SIM swap fraud works. Keep alerts on for any SIM change request, and pair this with a properly secured Android phone and strong two-factor authentication on your important accounts.

Frequently asked questions

Is eSIM free in India?

Converting an existing number is free with Jio, Airtel and Vi. A new connection costs whatever the plan costs.

Can I switch back to a physical SIM?

Yes. Request a replacement physical SIM from your operator, subject to their standard process.

Does eSIM drain more battery?

No meaningfully. Running two active lines uses slightly more power, but that is true of dual physical SIMs as well.

Can I use two eSIMs at once?

Depends on the phone. Many recent models support dual eSIM; others allow one eSIM plus one physical SIM.

Will my eSIM work if the phone is factory reset?

Usually not. Most resets remove the profile. Always confirm before resetting, and back up first using our phone data backup guide.

The bottom line

For anyone who travels, juggles two numbers, or is tired of a SIM tray that eats ejector pins, eSIM is a clear upgrade. The activation is a fifteen-minute job if you prepare, and a frustrating afternoon if you do not. Check your EID, keep a second internet source handy, and do not throw away the old SIM until the new profile has been live for a full day.
