Phone Does No Read Sim Cards Lg Leon Lte

Chosen Solution

My Lg suddenly stopped reading SIM cards. I have another phone in which the SIM does work. I noticed the SIM tray has a tiny bends at the tip from where you slide in the SIM. Pretty sure that has something to do with it.

Hi Wolfgang, let’s try some solutions: Cleaning the slot: Remove your batteryRemove your SIMUsing some types of textil, try to clean up slot carefully! If it’s possible, use PCB Spray to clean it. Also, check if the pins are OK without any visibly damage (compare with a new slot) or corrosion.Insert your SIM and boot your phone Wiping cache Turn OFF your phonePress POWER UP and VOLUME DOWN buttons together to enable fast-boot optionUsing volume buttons, navigate into the recovery menuChoose “wipe-cache partition” You can also make sure, that SIM card didn’t work in safe mode or airplane mode. You can check, if your phone did not change settings of preffered network like LTE, CDMA, GSM . The hardware issue is preferred - start cleaning, CAREFULLY! Let me know, if it’s ok or you need another solution. Regards.
