@AshikAliLive something is fishy..... no notification in selfcare or email nothing.. 

I had requested in selfcare and it was pending for 15 days.Then I called my area jto and within 1 hour plan was changed.and it was updated on selfcare at the same time .@Elavarasan like 3 weeks ago i requested to change the plan to Fibre value (100Mbps-3300GB) in the selfcare but it was still pending & some people in the forum told it wont work soo i lost interest in it..
I didn't give any request for plan change but today evening mine also got upgraded to 100mbps. I'm actually on ₹849 plan.@DMC i am also seeing the same plan as you Which BSNL plan have you opted for? | BSNL Bharat Fiber
Actually i opted for fiber value plan before two weeks just today only It got activated. I just checked with the BSNL customer care they said iam in fiber value plan only there are some issues with BSNL fup site and BSNL Pro app.
You better check with the bsnl customer care and the self care portal for your actual plan.
Did you requested to change your plan in BSNL office or self-care portal ? Or they itself changed your plan without your knowledge ?
