It is poor network because I have used this sim full costly internet data pack in this operator and it is costly std and local call rates are high in this sim and 2g and 3g packs are full costly in this operator and I have changed to another network and I prefer to my friends to take sim another dont take this sim .The main problem is the sim validity they does not provide validity for years. They just give validity of 3 months and we have to recharge for increasing the validity.
