Insert sim card

What is your problem with your Sim card? 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 Samsung SGH-E840 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. Use unlock code to unlock your Samsung SGH-E840. To get the code you have to submit network provider, country and IMEI number of the mobile. Make sure yourself whether you have knew the network provider to which your mobile is locked, country to which the locked network belongs to and IMEI number of your mobile. If not you can find the IMEI number in two ways:
1)Go to Options>status
2)Find IMEI on the back of your mobile, behind the battery.
3)Type *#06# and press call button. It will display your IMEI number.
You can find the network provider to which your mobile is currently locked by switch off your mobile and switch on it again. A logo of the locked network will get displayed on your mobile screen. After knew all these get the code from the site ,by submitting these to them. Unlock it yourself using unlocking instructions which is given in the site itself.
