Jai hind sir, my self nk /auto elect adusumalli sriramkumar of 6 kumaon regt. Sir, in my unit tellingvthat only postpaid connection is valid for anyone, no prepaid connection. Sir nowadays prepaid is much better cheaper than postpaid. (Ex 400 for unlimited calls and data for prepaid for 3 mnths, at the same cost for 1 mnth in postpaid). Pls think about on this issue. Noone escape from telecom security. Thats not impossible to an ordinary soldiers.in my unit prepaid simcards destroyed. Pls think about this sir,
