Are you using a BSNL mobile connection and wondering if you can switch to eSIM? You’re not alone. With more smartphones supporting eSIM technology, many BSNL users are now looking for a way to upgrade from physical SIM cards.
In this article, we’ll explain everything you need to know about converting your BSNL SIM to eSIM — including whether it’s possible today, when BSNL plans to launch eSIM support, and what you can do in the meantime if you need eSIM now.
I. Can You Convert a BSNL SIM to eSIM Today?
As of December 2025, BSNL has not yet launched eSIM services for its mobile customers.
That means you cannot convert your BSNL SIM to eSIM at this time.
While private telecom operators like Airtel, Jio, and Vi (Vodafone Idea) have supported eSIM for years, BSNL is still in the process of upgrading its network. eSIM service from BSNL is expected after full rollout of 4G and VoLTE, which is still ongoing.
II. What Is an eSIM and Why Do People Want It?
An eSIM (embedded SIM) is a digital SIM card that is built into your smartphone. Instead of inserting a physical SIM, you can activate your mobile service by scanning a QR code.
eSIM is useful because:
- You don’t need to carry or swap physical SIM cards
- It allows dual SIM functionality (e.g., one eSIM + one physical SIM)
- Switching between networks is faster and easier
- You reduce the risk of losing or damaging your SIM
Most modern smartphones, including iPhones (XS and newer), Pixel 4+, and Samsung Galaxy S20+, already support eSIM.
III. Is BSNL Planning to Launch eSIM?
Yes, BSNL does plan to introduce eSIM, but only after completing its 4G and VoLTE rollout.
Here’s what we know so far:
- In 2023, the Indian government approved BSNL’s 4G upgrade using indigenous technology (by TCS and C-DoT)
- As of late 2025, BSNL has launched 4G services in select circles (like Kerala, Punjab, and parts of Maharashtra)
- Pan-India 4G rollout is expected to complete in 2026
- eSIM and VoLTE will be launched after 4G is stable and nationwide
So, while BSNL is actively working toward modern features like eSIM, it is not available yet.
IV. What Can You Do If You Want eSIM Now?
If you want to use eSIM before BSNL launches it, you have two options:
1. Port Your BSNL Number to Airtel, Jio, or Vi
All three private operators in India support eSIM for:
- Postpaid users
- Selected prepaid users with eligible plans
To port your number, send an SMS: PORT <your BSNL number> to 1900 Then visit the nearest store of the new operator to complete the process and request eSIM activation.
2. Use an International eSIM for Data Only
If you just want data on eSIM, without porting your BSNL number, you can install an international eSIM that works in India.
For example, esimindia.net offers:
- Prepaid eSIMs that work with Indian networks like Airtel or Jio
- Instant activation via QR code
- No need to visit a store
This allows you to:
- Keep using your BSNL SIM for calls/OTPs
- Use the eSIM only for fast 4G/5G data
V. How Will BSNL eSIM Work Once It’s Launched?
Based on how Airtel and Jio handle eSIM, BSNL’s future eSIM process will likely work like this:
- You’ll send an SMS or visit a BSNL store to request eSIM
- BSNL will verify your ID and send you a QR code via email
- You’ll scan the QR code through your phone settings
- The eSIM profile will be activated, and your physical SIM will stop working
- You’ll now use BSNL services via eSIM
We will update this section with exact steps once BSNL officially announces eSIM support.
VI. Final Words: What Should You Do Now?
To summarize:
- BSNL does not currently offer eSIM (as of December 2025)
- eSIM support is expected after full 4G rollout, likely in 2026
- If you need eSIM now, either:
- Port to Airtel, Jio, or Vi, or
- Use a data-only eSIM alongside your BSNL SIM
