I guess your phone has not been unlocked yet. Unlocked phones do not have any specific carrier software and work with all GSM carriers. These include T-Mobile, Cingular and AAAA . Multi-band unlocked phones also will work with carriers in other countries.So I guess you need to unlock your phone so that u can enjoy in your country.

most probably you have not switch on the wireless mode. make sure you have wireless mode ON. than it will ask you for network code. than you can enter the code. or also make sure you are putting sim card in correct direction.
