SOURCE: SIM card not valid
Hi thee, I list here the possible reasons for "Sim card not valid"
1 - The phone is locked to a different network. In this case the phone usually accept the sim card the same , and has no network, but sometimes it may return the error message. Unlock the phone at a local shop.
2 - the SIM card is faulty. Test the card on a different phone to find out.
3 - The phone is faulty. Test the phone with different Sim cards, if the Phone returns same error on all cards, then the phone is faulty.

To change sim card follow below instruction
1) Turn off your mobile phone (press switch off button on top of the phone)
2) Remove back cover by pressing unlock button on the cover & slide cover upwards gently (please take care you would not force the camera cover)
3) Remove Battery From the phone & u will see ur current sim or sim slot
4) Check instruction & insert your sim
