I am talking about Command - ’’a hutchison telecom jv’’ cellular operator !
One of the best Cellphone service providers in Kolkata. Reception is good in most of the parts in Kolkata.
They have a strong Customer Care team. A very helpful indeed. They are always ready to illustrate most of the confusing things.
The web interface is good and excellent billing details provided in the web is an additional facility.
You will find many a place in and around Kolkata for making your payments. Plenty of shops keep cheque drop boxes. You can also pay by Card at any point at select outlets.
The voice plans are competitive. The bills are readable and easy to understand.
