With BSNL 3g sim card inserted, it shows 0 signal strength in Ejipura, Bangalore. Customer care says signal is available throughout Bangalore. I'm clueless. Can someone please help? I have inserted the SIM correctly, in fact the slot itself is designed to show the left and right corners' positions, so I can't be doing it wrong. Just to be sure, I inserted my Vodafone normal SIM card, and still 0 signal strength is shown.
