The offer is available on the recharge of all denominations, except top-up vouchers and valid for any number of recharges made during the offer period, it said.
The additional talk time - available for 31 days from the date of recharge - can be used for making calls to RIM phones in the circle, it added.
"This is our way of thanking our customers who helped us build a massive subscriber base," Shukla said.
RIM pre-paid recharge vouchers are available through 246 Reliance Web world stores and the one-lakh channel partner chains in the country.
