I ordered for HD + upgrade yesterday. I am using airtel SD connection for last four years. I am on south mega pack. The technician came with HD + box yesterday, replaced my SD box. I paid online Rs
999. Airtel will give cash back of Rs.400 in my account. 18 HD channels free for one month. The HD channels are not activated yet. Also one month recording free. After one month, Rs.100 for one year for recording. I don't see any clarity difference in SD channels. Will see HD channels after activated.
