The agreement follows last month's deal signed between RCom and Etisalat DB, earlier known as Swan Telecom, worth over Rs.10,000 crore.
Earlier this week, Reliance Infratel and S Tel signed an infrastructure agreement for sharing telecom towers, transmission for BTS sites and fibre backbone for intercity connectivity.
Reliance Communications will execute the agreement through its tower subsidiary Reliance Infratel. The pact covers six circles - Orissa, Bihar, Himachal Pradesh, Northeast, Assam and Jammu and Kashmir where the telecom operator plans to roll out its GSM services soon.
S Tel, a new telecom operator in the lndian marketplace, has acquired a Unified Access Services License (UASL) and spectrum to operate in the six circles.
Reliance Infratel is also pursuing such deals with other telecom operators. An RCom spokesperson declined to comment.
