Tata DOCOMO

Hi friends, i am going to discuss about the new technology which has been used by TATA in Sim cards in GSM network. The actual expansion of GSM network is, Global System for Mobile Network. This network is very essential and also very comfortable when compared with the existing network. This GSM is used about 212 countries. This GSM network is designed with the moderate security level. This uses the concept of pre-shared keys and challenge response. This GSM provides the services like localization, MMS, WAP and so on. The new Sim card which has been released by the reputed company called TATA just before few months. The name of this Sim card is TATA DOCOMO, in which GSM facility is used. This offers the facility to pay only for seconds for call rates,which you spend while you were in call. Generally, all kind of Sim network, offers only minute basis scheme. Thus DOCOMO plays a different role and helps us to reduce the amount we spend for call rates.
