@Crazyguy030601 not only in Bihar.Even if you step out of Kolkata(Rest of Bengal).No Ca.only 20mhz b3 is deployed b41 in rest of bengal also rare.i visited almost all states of india and my preception was based on that.Vi needs to deploy b41.they have b41 spectrum in all states except TN and KA.But they have not deployed b41 in many states.
