Excuse me: The short message in the inbox of the old man's Netcom 4G (no recycle bin, cloud backup) was deleted by mistake. How to recover with this machine? Answer accurately! thank you

If the 4G mobile phone of the aging mobile phone does not have the recycle bin and cloud backup function, and the message is deleted in the inbox by mistake, here are some possible recovery methods, but please note that the success rate of these methods may vary according to the specific situation:

Use data recovery software: This usually requires connecting the mobile phone to the computer and using special data recovery software for scanning and recovery. However, this method may not be effective for old computers that do not support USB mass storage or synchronize data with computers.

SIM card recovery: If the short message is stored on the SIM card, it can theoretically be recovered by some professional SIM card readers and software. But this requires professional equipment and technology, and not all deleted messages can be recovered.

Contact operators: In some cases, operators may keep users' SMS records, but this usually requires legal procedures to obtain, and not all operators will provide this service.

Manual memory recovery: If the deleted SMS is important and the content is still remembered, you can try to enter it manually or rewrite it. Because the function of the old machine is relatively limited, and there is no built-in recycle bin or cloud backup, it may be very difficult or impossible to recover the deleted SMS directly on this machine.

In most cases, if the data is not backed up in advance, the mistakenly deleted SMS may not be recovered. It is recommended to manually back up important information on a regular basis to prevent similar situations from happening.
