Srinivas Cellcom Mobile Operator is a very bad mobile operator to be used by anyone in their device. It has got nothing in it. Its network is very bad. It is not available is most of the places in india. Where ever I go I am facing network problem. The call gets dis connected automatically because of bad network. Its customer service is very careless and don't think about their customers. I complained them about network problem but they only said they will fix them but didn't did anything. Its charges and billings are also very high as compared to other mobile operators in this service.
