Re: K750 problem

You need to go to and download the firmware to flash your phone's model. this should correct the "insert sim" issue.
if that still does not help then you need to replaced the mainboard

If you do not remember the password for your privacy lock / phone lock then you will need to master reset the phone and that will reset the password back to the default password 00000000 (eight zeros). Please follow the steps below...

Steps to Master Reset the GSM Phones to company default settings

NOTE: Following the steps below will delete everything from the phone memory like contact numbers, images, music, messages.

1. Switch OFF the phone and take the SIM card out.

2. Switch it ON without the SIM card, the phone will say “insert SIM card”.

3. Enter the code *2767*2878# and wait for 10-20 seconds until the phone restarts automatically.

4. Now the phone will say “insert SIM card” again, put the SIM card back in and switch it ON.

Either your sim card is not seated correctly, the contacts are dirty, the sim card is dead, the copper contacts in the phone do not reach the sim card or the electronics in the phone are faulty. I guess the technician has already checked most of these common problems and the phone itself is to blame. Did you try another card?
