When my IDEA cellular SIM was disconnected and I post a complain at your end but No solution get. Then after few days again I submitted the required documents. and SIM registration activated.
But after few days again SMS is coming continuously at least twice a day. My SIM is active. But I am feeling irritation with such type of unwanted SMS-"Hamare kai prayason ke Baad bhi aapka CAF Hamein Prapt Nahin hua hai.Date.ke pahle CAF Na milne per .date.ko aapka mobile number bandh kiya ja sakta hai". Also feel inconvenient if I am out of station or at any other place from where I could not submit the document if SIM Disconnected.
