Idea, BSNL have the highest call drop complaints

Despite massive campaigns promising respite from call drops and superior network, telecom service provider Idea Cellular is one among the few operators who are facing the problem of frequent call drops.

According to the parameters laid down the Telecom Regulatory Authority of India (TRAI), a telecom network is considered as "worst affected cells" if more than 3 per cent of phone calls are not complete.

Bharat Sanchar Nigam Ltd (BSNL) and Etisalat are other two companies which fall in this category. From my personal experience I can say that calling from BSNL is a nightmare, as there are frequent dropped calls. Mobile number portability can rescue many people from these cell phone operators who don't want to change their number.
