You just got a new phone, or maybe you are simply tired of carrying that tiny plastic chip around. Either way, you have started asking the same question thousands of Indians are typing into Google or AI every day: How do I convert my physical SIM to eSIM?
The good news is that it is easier than you think, and you can do it from home in most cases. This guide walks you through the complete process for every major Indian carrier, tells you what to watch out for, and answers the questions nobody else bothers to address.
What exactly is an eSIM?
An eSIM (Embedded Subscriber Identity Module) is a digital SIM card built directly into your phone. There is no physical chip to insert or remove. Instead of visiting a store to swap a card, you activate your mobile plan by scanning a QR code or tapping through your phone settings.
Everything your physical SIM does, an eSIM does too. Calls, texts, mobile data, OTPs, all of it. The difference is that the eSIM is embedded into your device's hardware, so it cannot be lost, damaged, or accidentally dropped down a drain.
One important thing to understand from the start: converting your physical SIM to eSIM keeps your existing number. You are not getting a new number. You are simply moving your current number from a plastic chip to a digital profile on the same device.
Step 1: Check if Your Phone Supports eSIM
Before doing anything else, confirm that your device is eSIM-compatible. Here is the fastest way to check:
Dial *#06# and press call.
If you see a number labeled "EID" (which stands for eSIM Identifier) in the results, your phone supports eSIM. If there is no EID listed, your device does not support it.
Phones That Support eSIM in India
Most flagship phones released after 2020 support eSIM.
Some well-known ones include:
- Apple: iPhone XS, XR, and every model released after that. iPhones bought in the US from the iPhone 14 onwards are eSIM-only.
- Samsung: Galaxy S20 series and later. Note: Some Samsung models sold in India do not support eSIM, so always check your specific model.
- Google Pixel: Pixel 3 and later (with some regional exceptions).
- OnePlus: OnePlus 11, 12, and 13 support eSIM.
- Motorola, Xiaomi, OPPO, vivo: Select models support eSIM. Check your phone's spec sheet or the manufacturer's website to confirm.
Quick tip: If you bought a Samsung phone outside India (like a US or Canada model), verify eSIM compatibility separately, as some international variants behave differently with Indian carriers.
Step 2: Keep These Things Ready Before You Start
Rushing into the process without preparation is the top reason people run into trouble.
Here is what you need:
- An active email address that you can access immediately. Carriers send the QR code to this email, and in some cases the link expires within hours.
- Your phone's EID number. You got this in Step 1.
- A stable internet connection on a separate device, because once the conversion begins, your physical SIM will eventually be deactivated.
- Time. The whole process usually takes 30 minutes to 2 hours depending on your carrier.
Also keep in mind: as per TRAI (Telecom Regulatory Authority of India) rules, SMS services are disabled for 24 hours after eSIM activation. This is a fraud prevention measure. During that window, you will not be able to send or receive text messages, which means UPI, OTPs, and Google Pay will not work for that day. Plan accordingly.
How to Convert Jio SIM to eSIM
Jio has one of the smoothest eSIM conversion processes among Indian carriers. You have two options: through the MyJio app, or via SMS.
Method 1: Using the MyJio App
- Open the MyJio app on your phone.
- In the search bar at the top, type "eSIM" and tap on "Switch to eSIM".
- Confirm your email address and enter your device's EID number.
- An OTP will be sent to your Jio number. Enter it to verify.
- You will receive an automated phone call from Jio. Follow the prompts on the call carefully.
- After successful verification, Jio will send a QR code to your email.
- On your phone, go to Settings > Mobile Network > Add eSIM and scan the QR code.
Your eSIM profile will be installed and activated. The physical SIM will stop working once this is complete.
Method 2: Via SMS
This method works if you cannot access the app or prefer a simpler route.
- Send an SMS from your Jio number to 199 in this format: GETESIM <32-digit EID> <15-digit IMEI>
- Reply with "1" when you receive a confirmation SMS.
- Jio will send a QR code to your registered email.
- Scan the QR code through your phone's SIM settings.
The activation usually happens within 2 hours of scanning the QR code.
How to Convert Airtel SIM to eSIM
Airtel keeps the process simple and does not require you to visit a store.
Method 1: Via SMS to 121
- From your Airtel number, send an SMS to 121 in this format: eSIM <your registered email ID> (Example: eSIM yourname@gmail.com)
- You will get a confirmation SMS from 121. Reply with "1" within 60 seconds to confirm.
- Airtel will call you for identity verification. Stay available for this call. If you miss it, the request gets cancelled.
- After the call, a QR code will be sent to your email.
- Scan the QR code through your phone settings.
- iPhone: Settings > Mobile Data > Add Data Plan > Scan QR Code
- Android: Settings > Connections > SIM Card Manager > Add Mobile Plan > Scan QR Code
The eSIM should be active within a couple of hours. If you do not receive the QR code email, check your spam folder first.
Method 2: Airtel Thanks App
If you prefer using the app:
- Open the Airtel Thanks app.
- Go to Profile > My Account > eSIM Activation.
- Follow the on-screen instructions. The flow mirrors the SMS method but is more guided.
How to Convert VI (Vodafone Idea) SIM to eSIM
Vi's eSIM process differs slightly depending on whether you are a prepaid or postpaid user.
For Vi Postpaid Users
- Open the Vi app.
- Go to Help > Raise a Service Request.
- Select "Activate eSIM".
- Enter your EID and verify with an OTP sent to your number.
- Vi will send the QR code to your registered email once verified.
For Vi Prepaid Users
- Send an SMS to 199 in this format: esim <your email ID> (Example: esim yourname@gmail.com)
- You will receive a confirmation SMS. Reply with "ESIM" to proceed.
- Follow the further instructions sent by Vi via SMS.
What About BSNL?
As of 2025, BSNL has not yet launched eSIM services for its mobile customers. The state-owned carrier is still completing its 4G and VoLTE network upgrade using indigenous technology developed by TCS and C-DoT. BSNL plans to introduce eSIM after this rollout is complete, but there is no confirmed date yet.
If you are a BSNL user who wants eSIM, the only current option is to port your number to Airtel, Jio, or Vi first, and then convert to eSIM with the new carrier.
After the Conversion: What to Expect
Once your eSIM is active, a few things change:
- Your physical SIM slot is freed up, and you can insert a second SIM if your phone supports dual SIM.
- SMS will be unavailable for 24 hours (TRAI rule). You cannot use UPI, receive OTPs, or verify through text during this period.
- Apps like Google Pay, PhonePe, and similar UPI apps will need to be re-verified once SMS is restored.
- Your call history, contacts, and data are not affected by the switch.
- If you ever want to go back to a physical SIM, contact your carrier. They can reissue a physical SIM linked to your number.
Traveling Abroad? Here is Where Things Get More Interesting
Converting your Indian carrier SIM to eSIM is great for daily use in India. But when you travel internationally, a different kind of eSIM becomes very useful: a travel eSIM.
When you land in another country, your Indian SIM starts roaming, and roaming charges can be brutal. A travel eSIM lets you activate a local data plan in the destination country without buying a physical SIM at the airport or changing your Indian number.
This is where Olysim is worth knowing about.
Olysim offers eSIM plans for India and over 150 countries worldwide. If you are an Indian traveler heading abroad or a foreign visitor coming to India, Olysim lets you buy a data plan online, receive a QR code by email, and activate it in minutes. No queues, no paperwork, no physical SIM to juggle.
For China specifically, Olysim's plans start at ₹320 and run on the Jio, Airtel, Vodafone, and IDEA networks, giving you genuine local network quality across the country. You can also keep your Indian number active on your physical SIM while using the Olysim eSIM for data, which is the ideal dual-SIM setup for travelers.
Plans available for China through Olysim include:
- 1 GB valid for 3 days
- 3 GB valid for 7 days
- 5 GB valid for 10 days
- 10 GB valid for 15 days
- 20 GB valid for 30 days
- Daily data options (1 GB/day) for flexible use
- Daily unlimited data with high speed
For Indians heading abroad, Olysim has regional and country-specific plans across Europe, Southeast Asia, the Middle East, the US, and more. The per-GB pricing starts from $1.2, and there are no hidden fees. One QR code, one scan, and you are online.
The 24/7 support team is reachable via WhatsApp and app, which is genuinely useful when you are dealing with connectivity issues in a foreign country and cannot afford to wait for an email response.
Common Problems and How to Fix Them
"I did not get the QR code in my email." Check your spam folder. If it is not there, wait 30 minutes and then contact your carrier's customer support. Do not try to restart the process from scratch, as this can lock your number temporarily.
"My eSIM is active but SMS is not working." This is normal for the first 24 hours due to TRAI regulations. Wait it out. If SMS is still not working after 24 hours, call your carrier.
"Google Pay or UPI is not working after the switch." UPI apps register to your phone number via SMS verification. Since SMS is blocked for 24 hours post-conversion, you need to wait before re-verifying. After 24 hours, open the UPI app and go through the verification process again.
"The eSIM QR code expired before I scanned it." Most carriers' QR codes are valid for a limited window. Contact customer care and request a fresh QR code. You usually do not need to restart the entire process.
"My Samsung phone is not recognizing the eSIM." Some Samsung models bought outside India can have compatibility issues with Indian carriers. Try Jio first, as it tends to have broader device compatibility. If it still does not work, visit a carrier store in person.
"I accidentally deleted the eSIM profile." Contact your carrier immediately. Deleting an eSIM profile causes instant loss of network access. Carriers can re-issue a QR code, but you may need to complete identity verification again.
Tips to Make the Switch Smooth
Do it on a day you do not need your phone urgently: The 24-hour SMS blackout can catch people off guard. Avoid switching on a day when you have important payments, appointments, or OTP-heavy tasks lined up.
Use Wi-Fi calling during the blackout window: Most modern phones and carriers support Wi-Fi calling. Enable it before converting, so you can still receive calls even during the SMS restriction period.
Back up your phone before starting: The conversion itself does not erase data, but it is always good practice before any major network change.
Do not delete your eSIM profile unless you have a specific reason: Unlike a physical SIM you can re-insert, a deleted eSIM requires carrier intervention to restore.
Do it from home, not the airport: If you are converting because you are about to travel, do it a day or two before departure. Doing it at the last minute while rushing through an airport is a recipe for frustration.
Final Thoughts
Converting from a physical SIM to eSIM is one of those small changes that genuinely simplifies daily life. No more fishing for a SIM ejector tool, no tiny chip to lose, and the convenience of going dual-SIM without carrying two separate physical cards.
The process itself is straightforward for Jio and Airtel users, slightly more involved for Vi, and not yet available for BSNL. As long as your phone supports eSIM and you keep a few basics ready (email access, EID number, and ideally a free day), the switch usually goes without a hitch.
And if you travel internationally or are visiting India from abroad, look into a travel eSIM like Olysim to stay connected without the roaming bill shock. The ability to stay on your home number while using a local data profile is one of the most practical combinations modern eSIM technology makes possible.
