eSIM in India: How It Works, Which Networks Support It, and Should You Switch?

An eSIM is a SIM card built into your phone’s motherboard instead of a plastic chip you pop in and out. You still get a phone number, a data plan, and a carrier — nothing changes on that front. What changes is that switching phones now means scanning a QR code or tapping a button instead of ejecting a tray with a paperclip.

All three major Indian carriers — Jio, Airtel, and Vi — support eSIM conversion for free, and most phones priced above roughly ₹25,000 sold in India today have the hardware for it. The process usually takes under an hour, though carriers build in mandatory waiting periods that can stretch it to a few hours. This guide walks through what an eSIM actually is, how to convert on each network, which phones support it, and where people commonly get stuck.

Worth saying upfront: an eSIM is not automatically better for everyone. If you’re the kind of person who swaps SIMs between an old backup phone and a new one every few months, a physical SIM is still less friction. For most people, though, the trade-offs favor eSIM — especially once you’ve traveled internationally with one.

What an eSIM actually is

eSIM stands for “embedded SIM.” It’s a small chip soldered directly onto your phone’s logic board during manufacturing. Instead of loading a physical card with your carrier’s data, your carrier sends an encrypted profile over the internet that gets written onto that chip.

Functionally, it behaves exactly like a regular SIM once activated — same number, same network, same billing. The only real difference is how it gets onto your phone and how many profiles a single chip can store. Most modern eSIM phones can hold multiple carrier profiles at once (commonly 5-10, depending on the device) and switch between them in settings, though generally only one or two can be active for calls and data simultaneously depending on the phone.

Every eSIM-capable device has a unique 32-digit identifier called an EID (eSIM ID). You’ll need this number for every activation — you can find it by dialing *#06# on most phones, or checking Settings under “About Phone” or “Cellular.”

How eSIM activation works on Jio, Airtel, and Vi

All three carriers charge nothing for eSIM conversion, but each has a slightly different flow, and each builds in a mandatory verification delay — this isn’t a bug, it’s a Department of Telecommunications (DoT) anti-fraud requirement designed to stop someone from hijacking your number by requesting an eSIM swap without your knowledge.

Jio eSIM conversion

Open the MyJio app and look for “Switch to eSIM”, or send an SMS instead. The app route asks you to verify your email with an OTP and enter your device’s EID. After you submit an OTP sent to your registered mobile number, Jio enforces a 2-hour cooling-off period as per Department of Telecommunications guidelines. Once that passes, you’ll get an automated verification call from +91 2235072222 — answer it and enter the confirmation number it asks for. After that, your eSIM QR code arrives by SMS and email.

The SMS alternative: text GETESIM followed by your 32-digit EID and 15-digit IMEI to 199 from the Jio number you’re converting.

Airtel eSIM conversion

In the Airtel Thanks app, go to Home, then Shortcuts, then “Upgrade to eSIM,” pick your device, and enter your EID. You’ll get an OTP on your registered number to confirm the request. Airtel then calls you roughly 10 minutes after submission for verbal confirmation. Once approved, you download the eSIM profile, and Airtel activates it within about 2 hours of that download — though you’re given a 4-hour window to complete configuration before the request auto-cancels.

Vi eSIM conversion

In the Vi app, go to Help, then Raise a Service Request, then Activate eSIM, choose Android or iOS, and enter your EID (same device) or the new device’s EID (if moving to another phone). Confirm the OTP sent to your registered Vi number. After about 15 minutes, you can download the profile either via a device notification or by scanning the QR code Vi emails you. Make sure you’re on stable Wi-Fi before downloading — a dropped connection mid-download is a common failure point.

What happens after you get the QR code

The steps are nearly identical across carriers once you have the profile ready:

1. Go to Settings, then Network & Internet, then SIMs (Android) or Settings, then Cellular, then Add eSIM (iPhone).
2. Choose “Add eSIM” or “Use QR Code.”
3. Scan the code sent to your email, or tap the activation link or notification if you received it directly on the same device.
4. Wait for the profile to download and activate — this can take a few seconds to a couple of minutes.
5. Once confirmed, eject and remove your old physical SIM.
6. Restart your phone.

One detail that trips people up: after any SIM-to-eSIM conversion, expect your SMS service (including OTPs) to be barred for up to 24 hours as a security measure. Plan conversions when you’re not expecting time-sensitive OTPs — like an upcoming bank transaction or a delivery OTP.

Which phones sold in India support eSIM

eSIM support has moved well past flagship-only territory. As of mid-2026, it’s standard on recent iPhones (iPhone 14 series onward), most Samsung Galaxy S- and Z-series phones from the last few years, and increasingly on mid-range Android phones like the Pixel A-series and several Nothing, Motorola, and Samsung Galaxy A/FE models.

Budget phones under roughly ₹15,000 are where eSIM support gets patchy — many still ship with dual physical SIM trays only, since eSIM hardware adds a small manufacturing cost carriers don’t always pass on to the buyer as a discount. If eSIM matters to you, check the exact model’s spec sheet before buying, or cross-check against an updated list of eSIM-supported phones rather than assuming.

The real pros of switching to eSIM

Setting aside the marketing language, here’s where eSIM genuinely helps:

• Travel: Buying a local data eSIM for a trip abroad (through providers like Airalo or Holafly, or a destination carrier directly) means you land, scan a QR code you bought in advance, and you’re online — no hunting for a SIM shop at the airport, no losing your home SIM in transit.
• Dual SIM without dual trays: Many eSIM phones let you run a physical SIM plus an eSIM simultaneously, so you can keep a personal and work number on one device without needing a dual-SIM-tray phone.
• Theft resistance: A thief can’t pop out your eSIM and drop it into another phone the way they could with a physical card. The profile is tied to your device’s secure hardware and can be remotely disabled or wiped through your carrier’s app — though the phone itself may still connect via Wi-Fi or its data connection until you act, so speed still matters.
• No lost or damaged SIM trays: No tiny card to misplace, no tray pin to lose, no worn-out SIM contacts causing network drops.

The real cons, and where eSIM gets annoying

This is the part most guides skip:

• Switching phones is more friction, not less, in the moment. Moving a physical SIM to a new phone takes ten seconds. Moving an eSIM means going through your carrier’s transfer process again — Vi and Airtel both have separate transfer-to-new-device flows that involve the same OTP-and-EID dance, plus a wait.
• No fallback if your phone dies. If your only phone breaks and you don’t have another eSIM-compatible device handy, you can’t just move the SIM to an old feature phone to stay reachable. This matters more in India than in markets where everyone owns a spare smartphone.
• Feature phones almost never support eSIM. If you keep a basic keypad phone as a backup or for elderly family members, it almost certainly needs a physical SIM — eSIM has essentially no penetration in that segment.
• Selling or exchanging your phone requires an extra step. You have to remember to remove or transfer your eSIM profile before handing the device over.
• The waiting periods are genuinely inconvenient if you need connectivity immediately — the 2+ hour Jio cooling period or Airtel’s 10-minute callback aren’t things you can rush.

Common problems people run into

A few issues show up repeatedly across user reports and carrier support pages:

• QR code “already used” errors — each QR code is single-use. If your first scan attempt fails partway (usually due to a Wi-Fi drop), you often need to request a fresh profile rather than rescanning the same code.
• Verification call missed — Jio and Airtel’s callback verification will fail your request if you don’t answer or you enter the wrong confirmation code. You’ll need to restart the process.
• EID mismatch — entering the EID of the wrong device (easy to do if you’re converting on someone else’s phone temporarily) sends you a profile that won’t activate on your intended device.
• SMS/OTP blackout catching you off guard — as mentioned, expect 24 hours of no SMS after conversion. This has caught people off guard during bank OTP verification or e-commerce deliveries.

FAQ

Is eSIM conversion free in India?

Yes, across Jio, Airtel, and Vi, converting from physical SIM to eSIM does not carry a fee under normal circumstances.

Can I go back to a physical SIM after switching to eSIM?

Yes. You can request a new physical SIM from your carrier’s store or app, and it’ll go through similar KYC verification as any SIM replacement.

Does eSIM work with UPI apps and banking OTPs the same way?

Yes, once active, an eSIM receives SMS and OTPs identically to a physical SIM — the only difference is the 24-hour blackout window immediately after conversion, which applies to any SIM change, not eSIM specifically. For more on how UPI itself works on your phone, see our guide to UPI, NFC and tap-to-pay.

Can I use an eSIM and a physical SIM at the same time?

On most dual-SIM-capable eSIM phones, yes. Check your specific model, since implementations vary — some support two active connections, others let you store multiple profiles but keep only one active at a time.

What if I don’t know my phone’s EID?

Dial *#06# on your phone, or check Settings, then About Phone (Android) or Settings, then General, then About (iPhone) and look for “EID.”

Bottom line

eSIM is a genuine convenience upgrade for most smartphone users in India, particularly if you travel or want to avoid the low-grade risk of a stolen physical SIM. The activation process across Jio, Airtel, and Vi is free but involves mandatory security waits that range from about 15 minutes to a few hours — don’t start a conversion right before you need connectivity urgently. If you rely on a basic backup phone or swap SIMs between devices often, weigh that friction before switching. And if you’re setting up a new phone anyway, our guide to transferring data to a new phone covers the rest of the move.
