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.
