I am using tata indicom for last 12 years. it was the best service provider from the first and they provide best recharge options but after docomo has arrived the main problem is indicom has to be recharged through docomo offers. I always recharged my indicom with rs 222/- full talktime.
the main thing about indicom is that their tower or network which is very good. I always travel to several places where I watched airtel or other providers keep falling but indicom stays and helps to make call from any place. it may be in the mountain top or in some remote place.
dislikes- indicom has no special recharge options like other do. they dont have good phone set options. the sim is not attachable to other gsm phones.
only tata indicom in my total 12 years have not deducted any wrong charges as some other network do in name of sms and etc techniques. so I feel good with tata indicom and their network.
