This thread was started in 2018 with news link saying, "BSNL to start 5G trials in March2018" and we are here after 7 years - March 2025 and still all we are getting is tareek pe tareek, tareek pe tareek, tareek pe tareek.
Yes, BSNL 4G is available in town limits in Sivakasi. But NOT in main industrial areas, outside the city. VoLTE is still hit or miss. Coverage is pretty bad for 700MHz / Band 28 and do not ask about Band 1 coverage, Unicorn is less rare than that. I think BSNL needs to use FM Radio frequency like 98.2MHz to give full indoor 4G coverage.
Why are they NOT using Band 41 is beyond me? It is just a sw update right? When I went to BSNL exchange to give complaint reg 4G coverage issues, they recommended me to use "3G/2G Auto" mode. Indoor Coverage of 3G is also pretty bad here. So I once again started using "2G Only" mode now, with "5G Ready" SIM of BSNL.
