Showing bypass on my mobile and it is showing can’t use my sim

Hello Podilaprashanth,

Just to make sure we are understanding, is there a SIM error on your iPhone? If so, the following articles may help:

• If you see 'invalid SIM' or 'no SIM' on your iPhone or iPad - Apple Support

1. "Make sure that you have an active plan with your wireless carrier. 
2. Restart your iPhone or iPad.
3. Check for a carrier settings update. Go to Settings > General > About. If an update is available, you'll see a prompt to select OK or Update.
4. Remove your iPhone SIM card or iPad SIM card from the SIM card tray and then put the SIM card back. Make sure that the SIM tray closes completely and isn’t loose. If you use a SIM tray from a different model iPhone, iPad, or from another phone manufacturer, it might not fit properly.
5. Try using another SIM card. If you don't have one, go to your carrier's retail store and ask them to test with another SIM card. You might need to replace your SIM card."

• If you can't activate your iPhone or iPad (Wi-Fi + Cellular) - Apple Support

1. "Restart your iPhone or iPad.
2. If you're using a cellular-data connection, connect to a reliable Wi-Fi network instead.
3. If you get an error message on your iPhone or iPad that says the activation server is temporarily unavailable or cannot be reached when trying to activate, wait a few minutes, then repeat the previous steps.

If you still can't activate your iPhone or iPad, try again using your computer instead:

1. Make sure that you have the latest version of macOS or the latest version of iTunes.
2. Check that your computer has an internet connection.
3. With the cable that came with your iPhone or iPad, connect your iPhone or iPad to your computer. Locate your device on your computer.
4. Wait while your computer detects and activates your iPhone or iPad: 

• If an alert appears that says "Set up as New" or "Restore from Backup," it means your iPhone or iPad is activated.
• If you get an error message on your computer that says that the SIM card isn't compatible or is invalid, contact your carrier.
• If you get an error message that says the "activation information was invalid" or "activation information could not be obtained from the device," use recovery mode to restore your iPhone or iPad."

Let us know if we can help with anything else at all or if this doesn't settle your issue so we can look into this further with you. Thanks and have a fabulous day!
