BSNL to Launch 4G with Indigenous Gears, Jio too Switching to Desi

Despite multiple delays to launch 4G services, Bharat Sanchar Nigam Ltd (BSNL) - the state owned telecommunications service provider is seemed to be on the track to roll out the much awaited 4G-LTE services across the circles very soon.

As per the deal signed in August 2023, Tejas Networks-led consortium would be delivering 4G sites to BSNL worth Rs 7492 crore. Initially there was extensive trials run across the circles. On May 5, 2025 Tata backed telecom gear firm Tejas Networks announced that the company shipped more than 100,000 sites for BSNL's 4G/5G-ready network. This is one of the largest single-vendor RAN networks in the world ever delivered in record time. 

BSNL 4G-LTE Review (Initial Launch)

I had already shared the update regarding BSNL 4G, which is getting live across the country. I found live BSNL 4G in my locality since beginning of September 2024. 

Now time to test the 4G-LTE network by BSNL. It's completely home-made tech i.e. Indian companies Tejas and TCS made this 4G tech exclusively for BSNL. The SIM cards BSNL is now selling all are 5G-ready - no need to upgrade the SIM when BSNL launches 5G in future. Telecom Minister expects BSNL 4G will go mainstream by middle of 2025. 

BSNL 4G Goes Live Across Kolkata

State owned telecom service provider Bharat Sanchar Nigam Ltd (BSNL) is now busy in roll out of 4G networks across the country. In Kolkata circle, BSNL starts rolling out 4G network since May 2024. 

However me, living in suburbs of Kolkata did not find BSNL 4G signal in May, June, July, August. However since the begining of September 2024 I am getting BSNL 4G signals on my mobile phones.

BSNL 4G: ETA Unknown

On 15th August, 2024 BSNL announced that the state-run telco has deployed more than 15000+ 4G BTS across the country under Atmanirbhar Bharat initiative - the image you can see on the left was shared from BSNL's X (formerly Twitter) handle. 

However the target was 20,000 BTS installation. At the same time 'The Hindu Business Line' pointed out that DoT's Tarang website shows BSNL has only 10,000 active 4G BTS. 

BSNL's 4G service has been a long-due. Airtel was first Indian telecom operator to launch 4G services in 2012 in Kolkata. Spectrum and choosing equipment vendor were many of few roadblocks for the PSU.
