Hi Friends I used Tata Docomo connection for almost One and a half year. At the first time SMS service and Internet Service was too good, first first time I recharged a Rs 15/- and got 500 GB data for three days. By this I spent too much time using Docomo internet for Facebook, downloading songs etc. Bt call service was not good even if I recharged with power plans, it was good for only Docomo to Docomo connection . Bt to call other connection like Voda or Aircel Local plans cost me too expensive. And usually customer support service was not satisfactory. As I used a single sim slot phone Nokia X2-01 & my only no was given to many friends & relatives, I hesitate to change my no. But 3-4 months ago Net Problem of Docomo harassed me each and every time. That’s why I rejected the sim and bought a new smart phone and a Jio 4G sim.
