Once I bought the docomo SIM in udaipur, my areas has all connectivity so I bought this one as it is cheap. but but but its disappointed me a lot. I always searched for the network and I at home I found a place where I could talk .and there also phone calls got cut very often. later as the free balance got over 25 rs sim cost and balance 200rs, at the end of 2 months I changed my network.
I only mean to say is low cost is not a assurity of a quality product but in minds a doubt developes that why it is of low cost?
