Hi, when a phone says insert Sim,is either the Sim card or the Sim seater that allows the Sim to work is bad.

First try the Sim card on another phone and see if it will display insert Sim again.If it display that means the Sim card is damaged. But if no display,that means the Sim tray of your phone is damaged and will need to be replaced.

Contact a skill prsonnel.
Take care.

THERE IS A SOLUTION

if u cant even see the battery charging you have two possible errors:
1. the display
2.the mainboard

the easiest way to test this if u have an another phone to cross the displays to see if the problem still exists.
If the problem still exists your mainboard is damaged.

it may be sim damaged problem or it might be software problem so kindly check first with sim or switch off your phone for few min and insert sim and switch on your mobile

it could be that the contacts between the phone and the sim card are dirty and therefore you will get the error code. take the battery out and remove the sim card take a q-tip with some rubbing alchohol and clean the contact on sim card and the phone itself make sure not to use alot of alchohol. let them air dry then re-insert the sim and battery this should do the trick. the error warning should go away and the phone will be abale to receive the contact info from gthe sim card.. please rate this
