is tata whiz is gsm or cdme data card
good serrvice
recent i bought a TATA PHOTON WHIZ DATA CARD,my family are satisfied for bill and speed of this data card and they enjoy all day with this huge data usages ,now i am happy to bought this data card, but i went to my native Northeastern India network are so much trouble..
Personally i would like to say Tata photon plus connectivity is very good.. I am satisfied with it's connectivity.
my tata photon whiz speed is 153 but it is only giving 80 kbps and the signal bar is always high, i cannot talk to my relatives that live in Saudi Arabia.So i have a good advice for you never choose photon whiz.Photon plus is good use it !
