The two Apple phones are different. LD sends data to novice mobile phones. Why is there no text message?

Maybe you didn't check the message when you sent the message, because the message won't be sent automatically because of two different IDs, which is equivalent to making two phone calls.

If you want to get it back, you can try to log in to your original account and see if it was backed up in iCloud. If so, you can retrieve it from the cloud.

Of course, if there is no backup, don't worry. Theoretically, the Nand Flash IC integrated with mobile phone motherboard and computer hard disk data can be recovered, no matter whether the data is deleted by mistake or formatted. In this case, you can only use data recovery software to recover the computer data yourself.
