What Is eSIM and Should You Switch in India?

A friend of mine switched to eSIM on his new phone, felt very futuristic for a week, and then dropped the phone in a lake in Gandipet. Phone gone. SIM gone with it. He spent the next morning at an Airtel store getting his number back.

That story pretty much sums up eSIM: genuinely convenient most of the time, with a couple of situations where a physical SIM would have been simpler. Let’s look at what it is, how it works in India, and whether you should switch.

What Is an eSIM?

A regular SIM is a small plastic card you put in a tray. An eSIM (embedded SIM) is a chip that’s already built into your phone. Instead of inserting a card, you download your operator’s profile onto that chip – usually by scanning a QR code or through an app.

Your number, plan and everything else work exactly the same. Calls, SMS, data, OTPs, UPI – no difference. It’s just the way the SIM gets into the phone that changes.

Does My Phone Support eSIM?

Not all phones do. Generally:

• iPhones from the last several years support eSIM.
• Google Pixel phones support it.
• Samsung Galaxy flagships and some foldables support it. Many budget Galaxy models sold in India don’t.
• Some other brands’ premium models support it. Many budget and mid-range Android phones in India still don’t.

How to check:
– Look in Settings → Network & internet → SIMs (or Connections → SIM manager on Samsung). If you see an option like Add eSIM or Download a SIM, your phone supports it.
– Dial *#06# – if you see an EID number along with IMEI, the phone has an eSIM chip.
– Check your phone’s official spec page.

Also, your operator needs to support your specific model. Jio, Airtel and Vi all offer eSIM in India, but their supported device lists can differ. Check the operator’s website.

How to Get an eSIM in India

The process differs by operator and changes over time, so I’ll give you the general idea – check the official Jio, Airtel or Vi website for the current exact steps before you start.

Common options include:

1. Through an SMS request – you send a specific message from your registered number with details like your phone’s EID and IMEI, then confirm the request. The operator then sends you a QR code or activation details.
2. Through the operator’s app – MyJio, Airtel Thanks or Vi app may offer an eSIM option.
3. At a store – visit an official store with your ID. They’ll verify you and give you a QR code to scan. This is often the simplest for first-timers.

During the process, your physical SIM will stop working once the eSIM is activated. There may be a short gap of a few hours (it varies) when you don’t have service, so don’t do this on a day when you’re expecting an important OTP.

Safety tip: only follow instructions from the operator’s official website, app, or store. Scammers have been known to call people offering “eSIM upgrades” to hijack their numbers. If anyone calls you offering to help with eSIM activation, hang up.

The Advantages of eSIM

1. Dual SIM on phones with one tray

Many phones (especially iPhones in some regions, and compact phones) have one physical SIM slot. eSIM lets you use two numbers – say, a personal Jio and a work Airtel.

2. Harder for thieves to remove

A thief can pop out a physical SIM in seconds and switch off tracking. With eSIM, there’s nothing to remove, which may help with tracking a lost or stolen phone.

3. No SIM tray damage or lost cards

No tiny card to lose, no tray to bend, no SIM ejector pin hunt.

4. Easier to switch operators (sometimes)

You can port your number like normal and download the new operator’s eSIM, without waiting for a new physical card – depending on the operator’s process.

5. Travel convenience

When travelling abroad, you can add a local or travel eSIM for data while keeping your Indian number active. This is one of the most practical reasons people use eSIM.

The Disadvantages (Be Honest With Yourself)

1. Losing or breaking your phone is more hassle

With a physical SIM, if your phone breaks, you can move the SIM to an old phone in seconds. With eSIM, you’ll need to get a new eSIM issued – often meaning a store visit or an online process with verification. That’s what happened to my friend.

2. Switching phones takes a few steps

Moving to a new phone isn’t just “take out, put in”. Some phones support eSIM transfer during setup, but often you’ll need to request a new eSIM from your operator. Plan it before you switch.

3. Not every phone supports it

If you often switch between phones or use an old backup phone, eSIM can be limiting.

4. Repair centre visits

If your phone goes for repair and the motherboard is replaced, your eSIM goes with it. Get a new one issued after the repair.

5. SIM-swap fraud still exists

eSIM isn’t immune to SIM-swap fraud – where scammers trick the operator into transferring your number to their device. Protect your operator account and never share OTPs related to SIM changes.

Should You Switch? My Honest Take

eSIM makes sense if you:
– Have one physical SIM slot but need two numbers.
– Travel internationally and want to add travel data eSIMs.
– Rarely switch phones and keep your phone well protected.
– Like the extra security against SIM removal if stolen.

Stick with physical SIM if you:
– Change phones often or use a backup phone.
– Are setting up a phone for elderly parents who might need quick SIM swaps.
– Live far from an operator store and want an easy fallback.
– Use a budget phone that doesn’t support eSIM (obviously).

Many people use a mix: physical SIM for the main number and eSIM for a second number or travel. That’s a nice balance.

Tips If You Do Switch

1. Do it on a weekday when stores are open, in case something goes wrong.
2. Don’t do it before travelling or when expecting important OTPs.
3. Label your SIMs in phone settings (“Jio Personal”, “Airtel Work”) to avoid confusion.
4. Don’t delete the eSIM profile from your phone unless you’re sure – deleting it usually means you’ll need a fresh eSIM from your operator.
5. Before selling your phone, remove the eSIM profile and make sure your number is moved to your new phone first.
