my iphone are unavailable how to open this lock

If there is no timer and you wish to proceed with resetting, or if it is disabled/security lockout/unavailable, refer to this support article for various methods that you can use to resolve this. --> https://support.apple.com/HT212951 Which one you can use depends upon your equipment configuration. If you can use the iOS15.2+ method you may not need a computer.

How to reset your device if you are running iOS 15.2 or later:

Advance step: If you're using an eSIM, contact your carrier before trying these steps and ask for a QR code to set up your eSIM again.

1. From your device's Lock Screen, try to enter your passcode five times until the "[Device] Unavailable" screen appears and your device asks you to try again later.

2. When you're able to, continue to enter your passcode until the "Security Lockout" screen appears and you get the Erase [Device] option in the bottom corner of the screen.
 3. Tap Erase [Device], then tap Erase [Device] again to confirm.

4. Enter your Apple ID password to sign out of your Apple ID on your device.

5. Tap Erase [Device] to permanently delete all of your data and settings.

6. When your device restarts, follow the onscreen instructions to set up your device again, restore your data and settings from a backup, and set a new passcode.

You can only reach the "Security Lockout" screen if you have an active cellular or Wi-Fi connection and previously enabled Find My ( Find My - Official Apple Support ) on your device. After you try to enter your password ten times, your device will either erase itself or show Security Lockout and the option to Erase [Device] without a timer, depending on how you previously set up your device. 

If you can't follow the above steps (e.g., you are using an older iOS version), you can use a computer to reset your device, as described in this article --> If you forgot your iPhone passcode - Apple Support .

Thank you for the photo.

"No SIM":

"No SIM" is shown on the top-left corner of your screen. So, go here to fix that: If you See 'invalid SIM' or 'no SIM' on your iPhone or iPad - Apple Support

How to Unlock a Locked iPhone:

If you are locked out, then contact Apple Support. This is a theft deterrent. So, if you do not have the original proof of purchase (i.e. sales receipt or original packing), then you may not be able to get back in. So, set up a Genius Bar Appointment at your local Apple Store. There, you'd bring along a proof of purchase (i.e. sale receipt or original packaging) and the iPhone, itself.

Apple Support Contact Info:

• Contact Us - Choose Locations
• Proceed from there as necessary
• Note: Phone calls are taking a bit to go through at the moment, due to lots of calls. With the Coronavirus Pandemic, many are at home at the moment, with much time on their hands to contact Apple. So, just stay on the line, and you will get through :)
