TRAI makes per-second billing plan mandatory

The regulator has also allowed operators to change international long distance tariff plans on life time pre-paid cards. Earlier,TRAI had barred operated from changing any tariffs for a specific period after issuing a life time pre-paid card.

TRAI has also told the operators that for premium rate services,they can charge up to four times the normal rates. Premium services are essentially phone calls and SMS sent to participate in TV and radio programmes.
