eSIM technology is becoming increasingly popular in India, allowing users to activate a mobile connection without inserting a physical SIM card. If you’ve purchased an eSIM-compatible smartphone or want to switch from a traditional SIM card, the process is now simpler than ever.
Most major service providers in India support eSIM activation for eligible prepaid and postpaid customers. While the exact steps may vary slightly between providers, the overall process is quite similar.
This guide explains what an eSIM is, who can use it, how to request one, and how to activate it on your smartphone.
What Is an eSIM?
An eSIM (Embedded Subscriber Identity Module) is a digital SIM that is built directly into your smartphone, tablet, or smartwatch. Instead of inserting a plastic SIM card, your mobile service is activated by downloading a digital SIM profile provided by your service provider.
Once activated, an eSIM works just like a regular SIM card, enabling you to:
- Make and receive calls
- Send and receive SMS
- Use mobile data
- Access 4G or 5G services (where available)
Who Can Get an eSIM in India?
You can request an eSIM if:
- Your smartphone supports eSIM technology.
- Your mobile service provider offers eSIM services.
- Your mobile number is eligible for eSIM activation.
- Your device is carrier-compatible.
Before starting the process, ensure your phone supports eSIM and is running the latest software version.
How to Request an eSIM
Many service providers allow customers to request an eSIM through their official mobile app.
Step 1: Open Your Service Provider’s App
- Download and install your service provider’s official app.
- Sign in using the mobile number you want to convert to an eSIM.
- Go to the Home page.
- Find the Shortcuts or Services section.
- Select Upgrade to eSIM.
Step 2: Choose Your Device
You’ll be asked whether you want to activate the eSIM on:
- This device
- Another compatible device
Select the appropriate option.
Step 3: Enter Your Device’s EID
You’ll now need to enter your smartphone’s 32-digit EID (Embedded Identity Document) number.
The EID uniquely identifies your eSIM-compatible device.
You can usually find it by:
- Opening Settings
- Going to About Phone
- Selecting SIM Status or eSIM Information
Alternatively, some phones display the EID by dialing *#06#.
Verify Your Mobile Number
After submitting the request, your service provider will send a One-Time Password (OTP) to your registered mobile number.
Enter the OTP to verify your identity.
This step helps protect your mobile account from unauthorized requests.
Complete Verification
Once your request is submitted:
- Your service provider may call your registered number for confirmation.
- Confirm that you requested the eSIM conversion.
- After verification, your request will be processed.
The verification process typically begins within a few minutes after submitting the request.
Download and Configure the eSIM
Once your request is approved:
- Follow the instructions provided by your service provider.
- Download the eSIM profile to your smartphone.
- Install and activate the profile.
Depending on your provider, activation may take up to 2 hours after the profile has been downloaded.
Final Steps After Activation
Once your eSIM is active:
- Make sure the eSIM profile is enabled.
- Remove the physical SIM card from your phone.
- Restart your smartphone.
- Check whether calls, SMS, and mobile data are working properly.
Your device should now operate entirely using the eSIM.
Important Things to Remember
Before converting your SIM to an eSIM, keep these important points in mind.
Complete the Entire Process
Once you begin the eSIM conversion, complete every step without interruption to avoid activation delays.
Never Delete the eSIM Profile
Avoid tapping the Delete eSIM option in your phone settings.
Deleting the profile removes your mobile connection and may require contacting your service provider to activate it again.
SMS Restrictions After Activation
After your eSIM request is completed, incoming and outgoing SMS services—including OTP messages—may remain temporarily unavailable for up to 24 hours as part of security measures.
Voice calls and mobile data availability may vary depending on your provider.
Remove the Physical SIM
After successfully activating your eSIM:
- Enable the new eSIM profile.
- Remove the old physical SIM card.
- Restart the device.
This helps prevent any SIM conflicts.
Keep Your EID Private
Your device’s EID is unique and should never be shared with unknown individuals.
Sharing it could potentially expose your mobile account to unauthorized access attempts.
If Your eSIM Phone Is Lost
If your eSIM-enabled phone is lost or stolen:
- Contact your service provider immediately.
- Request your mobile service to be temporarily blocked.
- Visit the nearest customer service center if additional assistance is required.
Acting quickly helps protect your mobile number from misuse.
Getting a New eSIM Connection
If you’re applying for a completely new mobile connection with eSIM instead of converting an existing SIM, most service providers require you to visit an authorized retail store or customer service center for identity verification and activation.
Troubleshooting Common eSIM Issues
If your eSIM doesn’t activate, try the following:
- Restart your smartphone.
- Ensure your device supports eSIM.
- Verify that the EID entered is correct.
- Update your phone to the latest software version.
- Check that your internet connection is stable during activation.
- Contact your service provider if the activation takes longer than expected.
Most activation issues are resolved quickly once the profile is reissued or downloaded again.
Benefits of Using an eSIM
Choosing an eSIM offers several advantages over a traditional SIM card.
Some of the key benefits include:
- No physical SIM card required
- Faster activation
- Easier carrier switching
- Support for multiple mobile profiles on compatible devices
- Better protection against SIM loss or damage
- Ideal for international travelers
- Improved water and dust resistance in many smartphones
Final Verdict
An eSIM offers a convenient and modern way to stay connected without using a physical SIM card. If your smartphone and service provider support eSIM, upgrading is generally a straightforward process that can be completed through the provider’s mobile app or customer service.
Before starting, make sure your device is compatible, your EID is available, and you carefully follow each activation step. Once activated, you’ll enjoy the same calling, messaging, and mobile data services as a traditional SIM, along with the added flexibility and convenience that eSIM technology provides.
