Sms mysterious mailbox

In fact, this problem is because the information received by your mobile phone is not SMS or MMS, but a kind of network information, such as service information and WAP information. Some mobile phones do not have this information in their inboxes. You can open the browser of your mobile phone, carefully look for the options inside, and you can find the relevant "service information" or "WAP information" and delete the information inside, but I don't know what mobile phone you are using now, but it doesn't matter. The information in any mobile phone is similar. If you don't have this information in your inbox, it must be saved in your browser or a specific storage location. Just delete the information I mentioned and your problem will be solved. Pick up the phone and delete it according to my inference ~ ~ ~
