I have opened a free 139 mailbox. I want to send important text messages on my phone to the mailbox and store them, but...

Does Fetion know?

Log in to the computer using Fetion, which is bound to your mobile phone number, use Fetion to send a text message to your mobile phone, extract the number of your text message and save it as a contact, and then add the number you want to save Important text messages are forwarded to the Feixin you just saved.

After Fetion receives the text message, it copies and saves the content to the mailbox
