Hi.I've got the sim card error problem with my LG G3 phone.

[Android Central Question]

I searched on the web and also tried some of your solution for others but it doesn't work.

Welcome to Android Central! What's the exact error message? Have you already tried removing the SIM card, making sure the contacts are clean, and then reinserting? You can also ask your carrier if a replacement SIM card is needed.
