Vodafone had earlier stated that Most of the revenue (I think around 85%) comes from the top 10 circles. That doesn't mean that other circle don't need to be focused on but considering the cash crunch, they cannot afford to put any money in Circle C group which includes Bihar & Jharkhand. The spectrum price is lower in circle C but operational costs still remain.
So circle C folks should hold their breath for any improvement for a while. The networks in my circle are garbage and it's a real pain the butt to find a operator that works everywhere. Thank God for
Airtel Xstream otherwise Vodafone B41 or Jio B5 was the only savior here. Airtel is garbage in my city for here and they don't put any efforts in improving the network.
Another issue is my mother's work place where Jio and Vodafone are dead and only Airtel works albeit slowly. It's only 7 KMs outside the city and this is the condition when she needs the internet for online classes.
