Just received a call from Tata Indicom customer care center.
They wanted to ask the reason behind lowered usage on the Indicom number I have.
The reason is rather simple… I have switched to Aircel on Google Nexus One for my primary phone.
He accepted the simple reasoning and told me to call 121 in case I faced any problems with the Indicom number.
Nice and sweet. Cool.
Update: Got another call after a couple of hours. Exactly the same conversation. It got annoying.
