No SIM/SIM Failure

BoyRacer — Wed, 05 Jan 2022 14:37:10 GMT

Recently my phone started registering as No SIM randomly meaning I received no texts or phone calls. I would just turn it off and turn it back on and it would be fine. However this was happening about once a month and is now accelerating to a few times a week which has become a problem. Is my SIM faulty or is there another issue? Thanks.

It sounds like there may be a contact problem with the phone. Have you tried putting your SIM into another phone? This should tell you if it's the SIM or the phone. If it's the SIM @BoyRacer before you run out and replace the SIM. Contact the moderators and ask the to reset it. Click on the green questionmark in the white circle at the bottom right of your screen . This connects to the autobot Simon.

Try removing your sim and then put it back in. Also reboot your phone.

@BoyRacer That problem could be caused but a number of issues:

loose sim card

Sim card contacts need cleaning

SIM tray problem

Soldering issues on motherboard (LG phones)

I agree with the possibility of hardware problem. SIM cards are pretty rugged. My current SIM card is more than 3 years old and have been inserted into dozens of different phones. There's some screech marks on the SIM card but it has never shown signs of failure. Also SIM cards are unlikely to fail intermittently out of the blue.

@BoyRacer

What phone are you using right now, which brand and model?

Can you test your sim card in another phone?

@BoyRacer As mentioned test your SIM in another device and if it works then it's time for a new phone.
