FEW DAYS AGO ONLY I BOUGHT A TATA DOCOMO SIM BUT I AM NOT AT ALL SATISFIED WITH TATA DOCOMO NETWORK.FIRST OF ALL THE NETWORK OF TATA DOCOMO IS WORST OF ALL NETWORKS I SOMETIMES DONT EVEN GET ANY NETWORK IN MY HOME ALSO WHICH MAKES MY CELLPHONE DEAD AND CREATES A LOT OF PROBLEMS TO CONTACT WITH OTHERS.THE INTERNET CONNECTION OF TATA DOCOMO IS ALSO WORST YOU DONT GET ANY SPEED IN YOUR NETWORK, WHICH MAKES VERY DIFFICULT TO DOWNLOAD SONGS, MOVIE, PDF FILES AND ETC.THE CUSTOMER SERVICE OF TATA DOCOMO IS ALSO VERY BAD .WHENEVER I CALL IN THEIR CUSTOMER CARE FOR ANY QUERIES OR HELP, THEY DONT SUPPLY ME INFORMATION UP TO MY NECESSITIES.AT LAST THE CHARGES OF THE NETWORK IS QUITE HIGH ACCORDING TO THE BENEFITS YOU GET.I WANT TO SAY THAT I AM NOT AT ALL SATISFIED WITH THIS NETWORK.
