Reliance Mobile (Smart GSM) Kolkata has introduced a New Special Tariff Voucher of Rs.18 for Kolkata. It seems though Reliance doesn’t want to lag behind others and are much re-enforsed to join the tariff war unlike other operators in state. This special voucher will enable a Reliance customer to make lower calls from R2R for a year. The new STV @ Rs.18 is for the prepaid segment and has a validity of one year and offers local R2R calls @ 25p/min. Charges for local calls to other phones are 50p/min and STD costs Rs.1.20/min.Local SMS will cost Re.1 and for sending National SMS customer has to bear Rs.1.50. Along with this it also offers Night calling facility @ 10p/min within its own network between 11PM-6AM and this STV can be clubbed with other plans also.I say this is the most cheapest plan available for making R2R calls and that too the plan is valid for a year. So customers can enjoy 365 days of calling at just 25p/min during the day and 10p/min at night. The wind doesn’t stop here.. Local charges are slashed to 50p/min and gives the freedom to call any phone and the whole tariff costs just Rs.18. Wow..!! Reliance users should get a hold of this.
