Is your phone shows the "No Sim" or "Insert Sim" or "Sim Rejected" or "Invalid Sim" error? If it is so I am here to help you. If your Blackberry 8100 shows the "No Sim" or "Insert Sim" error then remove your Sim from your mobile and place it again correctly. If your mobile shows the error message "Invalid Sim" or "Sim Rejected" the your phone is locked to a particular network. To fix this problem you need to unlock it.
