Why didn't Huawei hear from other iPhones after the old iPhone was cloned?

To change a new phone, you need to turn off the iMessage function of the old phone first, and then turn on the iMessage function in the new phone (in Settings and Information).

Then check whether the sending and receiving address in iMessage contains the account used for iMessage communication, and if not, add it.

If iMessage still doesn't work normally after setting, you need to turn iMessage on and off several times to activate iMessage function.
