i have a china made mobile n8 but after inserted it shows invalid sim what's the solution of this problem

you need to have the phone exchanged for a new one or take it to a service center and have the software reflash.

You should try reinstalling the firmware using the nokia software updater.

i have mt6227
i think its infected by virus
it just restarts when the sim card is inserted.
i don't have its system files also
can u please send me the files needed for my phone
my e-mail id is [email protected]

Try to see if there is something which can cause to electric circuit shortage around the sim card.

you have software problem. have your fon reprogrammed.

My phones displays the message Insert SIM Card even though it has the SIM Card.
