After I had posted http://criticscloud.com/quick-review/23/idea-connection-activation-troubles, I got call from the same preverification team lady as well as the representative who had given the sim. Both could connect to me without any issue. However, the physical verification team cannot connect to me. This strengthens my doubt that they have just made it up to meet the SLA. Or let them share the exact times at which they had called me.
