why my ipad 4 ios 10.3.3 not detected my physic SIM card?

You can try the steps in this Apple support article:

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

Without working cell service on your iPad, you will need to have a Wi-Fi network that you can connect to.

Regards.

Confirm with your carrier that your SIM is still active. If it is, you may need get a new SIM from them. If that still fails, then as legend103 said, you may have a hardware fault with your iPad.

Apple has some additional suggestions here that may help:

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

We are not clairvoyant, and only know what you tell us about the issue and about what you’ve already tried.

…also the link you give me it not contain the error im still get "activation failed" do you have any solution for this error or tomorrow let me tell them abt this too? i think my phone and my ipad could be trash

This iPad is a dozen years old, is 32-bit, and may have well be having issues with activation just because of its age, or the iPad might have hardware issues with the SIM or cellular connectivity, or maybe the SIM you are using might have issues.

Contact Apple Support. Given how old this iPad is, you may well need assistance activating it.

If you do get this iPad activated, a 32-bit iPad running iOS 10 can run very little from the app store, and even the built-in apps including Safari won’t be able to make what are now considered to be secure network connections. It won’t be all that useful.

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

If you are experiencing difficulties with (re)activation of your iPad, you may have more success if you connect your iPad to a Windows PC (with iTunes for Windows installed - or more recent Apple Devices App) or a Mac computer (with iTunes or Finder - as appropriate for the installed version of macOS). Once connected to your computer, your iPad will be detected - and you should be able to activate using iTunes.

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 iPad, connect your iPad to your computer. Locate your device on your computer.
4. Wait while your computer detects and activates your iPad:

• If you see an alert that shows "Set up as New" or "Restore from Backup", it means your iPad is activated.
• 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.

A restart of your WiFi Router may also be helpful.

To restart you home router, disconnect power - then wait at least 30 seconds before restarting. When you router has rebooted (which may take several minutes), force-restart your iPad:

Force restart iPad (models with the Home button)

Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.

Should it be necessary to escalate your issue to Apple Support, the quickest route to engaging with Apple Support will be via the Support link at top-right or bottom-left of this page - or using this link:

Official Apple Support

You have a very old iPad. There are two likely possibilities...

1) It is very likely that your physical SIM is "provisioned", by the Cellular Carrier to which the SIM belongs, for capabilities or features that your obsolete iPad does not support.

2) Alternatively, your iPad might have a hardware fault.

Do you have a working Wi-Fi network available? If not, then you will not be able to activate the iPad. If you have a Wi-Fi network that you've confirmed that is working and activation still fails after following all the suggestions in the support article to which I linked, then you may indeed have a broken iPad. The 4th-generation iPad is no longer supported by Apple, so Apple Support is not likely to be able to help you and you'll probably need to find an independent repair shop to take the iPad to for further assistance.
