Hi!
Yes, you can recover lost or deleted data from an iPhone 11. There are several ways to do this. One of the ways is to use an iPhone data recovery software like iPhone Data Recovery or easeus MobiSaver. These programs can help you quickly scan iPhone 11 data and recover it quickly. To use iPhone Data Recovery, you must first download and install the software on your computer. Once installed, launch the program and connect your iPhone to your computer via USB cable. After connecting your iPhone, select the file types you want to recover and start scanning the device. Once the scan is complete, you can preview the recoverable data and select the ones you want to recover. Finally, click on "Recover" button to save the recovered data on your computer.
Another way to recover deleted data is to restore it from an iTunes or iCloud backup if you have one. If you have backed up your data to iTunes or iCloud before accidentally deleting it, you can restore the data from there. To restore data from an iCloud backup, follow these steps:
1) Turn on your device. You should see a greeting screen. If you have already configured your device, you must initialize its contents before following these steps to restore it from the backup.
2) Follow the on-screen setup steps until the Apps and Data screen appears, then tap Restore from iCloud Backup.
3) Sign in to iCloud with your Apple ID.
4) Choose a backup. Check the date and size of each backup and select the most relevant one.
5) When prompted, sign in with your Apple ID to restore apps and purchases.
6) After choosing a backup, the transfer starts. Keep connected to the Wi-Fi network and wait for the progress bar to appear and complete. Completing the progress bar can take from minutes to an hour depending on the backup size and network speed.
As for the contacts on your physical SIM, you may be able to retrieve them if you have saved them on the SIM. Otherwise, you may have to use any of the above mentioned methods to recover your contacts.
I hope I helped you!
