I have used telenor from 2011 that means 7 years. It is the best calling operator from that time to this time also. Firstly the network of this operator is very good and now telenor has become 4G operator it gives many useful offers like locl/std calles 1/2 paisa/sec. This was the first operator that give benifit to many people. It has also given me offers like 10rs.= 30rs. talktime.Its costumer services I also very good. Now you can know telenor is the best operator. It is less chargable and more useful. So I prefer to buy telenor.Thankyou!
