Acording to news reports, DoT has sought the finance ministry's views on TRAI's recommendations on reducing the spectrum fee from 6 per cent of the adjusted gross revenue to 4 per cent. DoT has also sought the ministry's opinion on the proposed imposition of a one-time fee for next-generation mobile services. It feels that levying an entry fee may not be a legally sound move as the existing telecom licences permit operators to offer all types of telecom services and does not distinguish between 2G and 3G services. In fact, there is a clause that specifies that there cannot be an entry fee for a new service. However, the Tatas have proposed an entry fee of Rs 15 billion for 3G spectrum, a move opposed by GSM operators. The finance ministry, reportedly, prefers a revenuesharing arrangement.
