BSNL Homegrown 4G with TCS, Tejas, and C-Dot faces Connectivity Issues

Since the launch of Bharat Sanchar Nigam Limited (BSNL) homegrown 4G service, users have been continuously reporting connectivity issues like call drops, sometimes slow speed, and no voice in between the calls. Kerala, being the strongest circle of BSNL have also reported the rising complaints regarding the connectivity issue.

It’s one of the main reasons why users are not choosing BSNL and prefer private players, even when they are charging more than the PSU. Back in September 2025, our prime minister, Modiji, launched the indigenous developed 4G service and pushed India into the list of a few selected countries that can develop and deploy the telecom infrastructure on their own.

The event was a major milestone in the telecom sector and made India self-reliant in the telecom industry. However, the system is not as refined as other global vendors like Erricson, ZTE, and Nokia, but still, a lot of issues have already been fixed.

The homegrown network has been developed by the Centre for Development of Telematics (C-DOT, a government entity) and Tata Consultancy Services (TCS), while being in collaboration with Tejas Networks.

Complaints about 4G Service

Many users have reported that whenever they call someone who is active, they hear an automated message stating that the dialed number is switched off or unavailable to talk. To make it worse, sometimes callers hear the ringing sound, but the recipient’s phone never rings.

Even when the call is connected, the voice is not clear or sometimes not even heard clearly. But one thing that is working quite well for the BSNL is its Data Service, because very few people have complained about their data service.

As per the latest report by the Telecom Regulatory Authority of India (TRAI), Bharat Sanchar Nigam Limited has added about 12 lakhs new subscribers in the 2nd last quarter. However, things take a wrong turn in December, when BSNL loses around 2.06 lakh subscribers, suggesting a sharp decline in additions and disturbed network quality.
