To fix a non-working SIM card using rubber gum, follow these steps:

Remove the SIM card from your device carefully.
Inspect the SIM card for any visible damage or dirt.
Take a small piece of rubber gum, preferably unused.
Gently rub the rubber gum on the gold contacts of the SIM card.
Ensure that the contacts are completely covered with a thin layer of rubber gum.
Insert the SIM card back into your device, making sure it is properly aligned.
Restart your device and check if the SIM card is now working.
If the issue persists, repeat the process a few more times, applying the rubber gum on the contacts each time.
Remember, this method should only be used as a temporary solution. It is advisable to contact your network provider for a replacement SIM card if the problem continues.
