Hi Vijay,Are you going to post the step-by-step instructions to enable DATA back on Reliance CDMA for Kitkat users? 
Hi, 
I had the same issue after upgrading to kit kat 4.4.2. 
Simply, to try my luck, I went to reliance store a bought a new OMH sim for Rs 4/-. 
To my surprise when I inserted the new sim, I got an option to add APN. 
I created a new rcomnet apn and gave my mobile no. as username and password. 
After a few seconds I was connected to evdo network. To my surprise, with the new sim, wifi tethering is also working without any Verizon subscription check.
