If the sim came with the phone that is an American phone you need a sim for an African mobile phone network in your country or you need to contact the American mobile phone network provider to get the unlock code. The phone may be locked onto a particular USA mobile phone radio network and you would need to know what network it is locked to. There are web sites that offer to get the unlock code on the internet for mobiles locked on a particular mobile network but I have not had experience using them and do not know how successful they are to try and unlock a mobile from a particular mobile network. You will find this out when you change the sim card in the phone for a local African mobile phone provider in Africa
see http://www.youtube.com/watch?v=dC0KKX-2bn8

with an USA sim card and USA mobile network provider you will pay lots of money in Roaming charges which you would wish to avoid by using a local African mobile provider.
A local provider may be able to help you unlock the phone from the particular mobile network if it is locked on a USA mobile network.

There must be a mobile network provider in Africa that can work on your mobile phone type for it to work with that mobile network providers correct sim card.

Another source of problem could be if the phone has been reported as stolen the IMEI may not work due to being blacklisted and disabled.

You may try default phone and security code to remove restrictions.
ur defalt phones codes is 12345 or 00000 u can use it
Default 4 Digit user code: 1234 or 0000
Default 6 Digit Security code: 123456 or 000000

Type *#06# at the mobile screen to know IMEI no of your mobile.
