eSIM in India: How to Activate on Jio, Airtel and Vi

Activating an eSIM in India is one of those tasks that takes five minutes when you know the process and a frustrating afternoon when you do not. An eSIM is a SIM profile downloaded into a chip built into your phone — no plastic card, no SIM ejector pin — and all three major private operators, Jio, Airtel and Vi, now issue eSIMs for both prepaid and postpaid, with BSNL availability more limited. This guide walks through eSIM activation on each operator, the prerequisites that trip people up, how conversions and phone changes work, and what to do when the QR code refuses to cooperate.

Before You Start: The Three Prerequisites

First, your phone must support eSIM and be carrier-unlocked. Most flagship and upper-midrange phones sold in India since roughly 2020 qualify — iPhones from XS/XR onward, Samsung flagships from the S20 era, Google Pixels from the 3 onward, and a growing list of others — but many budget models still lack the hardware, so check your model’s specifications rather than assuming. You can verify on most Android phones under Settings, then Connections or Network, looking for an “Add eSIM” or “Download SIM” option; on iPhone, under Settings, Cellular. Second, your number’s KYC details should be current, because operators verify identity before issuing a profile. Third, you need a working email address on record for QR delivery on some operators, and your existing SIM active for SMS confirmations. Converting during a busy workday is unwise: the switchover includes a short no-service window.

How to Activate eSIM on Jio

For an existing Jio number, the standard route is SMS-based: send GETESIM followed by your device’s EID and IMEI (both found in Settings or by dialling *#06#) to 199 from the Jio number. You receive configuration details and, after email or app verification, a QR code or direct profile push. Scan the QR under Add eSIM in your phone settings, wait for the profile to install and the old SIM to deactivate, and the line goes live on the eSIM. New Jio customers can request an eSIM at activation through the operator’s app-based onboarding or a store. If you swap phones later, the process repeats with the new device’s EID — profiles do not transfer by themselves.

How to Activate eSIM on Airtel

Airtel uses a similar SMS flow: send eSIM followed by your registered email address to 121 from the Airtel number, confirm the request by SMS within the stated window, and complete any verification call or app step. The QR code arrives by email; scanning it installs the profile, and the physical SIM deactivates shortly after. Airtel also supports eSIM issuance through the Airtel Thanks app and stores for new connections, and doorstep KYC in many cities. Keep the QR email — some operators allow reuse until the profile is installed, but treat each QR as single-use and request a fresh one for a new device.

How to Activate eSIM on Vi

Vi’s flow follows the same shape: an SMS from the Vi number (the keyword and shortcode are listed in the Vi app’s eSIM section), an email-delivered QR code, and a confirmation step before the switch. Vi has historically limited eSIM to select circles and postpaid first, expanding prepaid coverage over time, so check availability for your circle in the app first. On all three operators, the exact keywords and steps get refined periodically — if an SMS keyword bounces, the operator app’s eSIM section is the current source of truth.

Common Problems and Fixes

The QR code will not scan or install

Ensure the phone is on Wi-Fi or another data source during installation — the profile downloads over the network. Clean the screen displaying the QR, brighten it, or use the manual entry option (SM-DP+ address and activation code) that accompanies most QR emails. If the profile errors out repeatedly, request a fresh QR; expired codes are the most common culprit.

No service after activation

A short outage during switchover is normal. Beyond an hour, toggle airplane mode, reboot, and confirm the eSIM line is enabled and set as default for calls and data in settings. Dual-SIM users should re-check which line handles data — the defaults sometimes reset.

Lost or reset phone

An eSIM cannot be moved by swapping plastic. Contact the operator (store, app or helpline), verify your identity, and have a replacement profile issued — the same process as replacing a lost physical SIM, minus the courier wait.

Should You Convert at All?

For most users, yes, eventually. eSIMs free the physical slot in dual-SIM phones (a cheap second pack becomes painless — see what to look for under ₹200), they cannot be stolen out of a lost phone, and they make travel far easier: a foreign travel eSIM can occupy the digital slot while your Indian SIM keeps OTPs flowing, a setup we detail in our international roaming guide. The main costs are friction when changing phones frequently and dependence on operator support for reissuance. If you change handsets often, weigh that friction honestly; if not, convert on a quiet evening and enjoy the flexibility.

FAQ: eSIM in India

Does eSIM cost extra in India?

Conversion from a physical SIM is typically free on the major operators, and your plan, number and benefits carry over unchanged. Replacement profiles after a lost phone are also generally issued without charge, subject to identity verification.

Can I use two eSIMs at once?

Many recent phones store multiple eSIM profiles and can keep two lines active simultaneously — including combinations of physical SIM plus eSIM or dual eSIM on newer iPhones and flagships. Check your specific model’s active-line limit before planning around it.

Can I go back to a physical SIM later?

Yes. Operators will convert an eSIM back to a plastic SIM through the same store or app channels, usually free or for a nominal card fee. The number and plan are unaffected either way.
