The sign of mobile phone short message.

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 don't have this information in their inboxes. You can open the browser of your mobile phone and carefully search for the options inside, so that 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, you must save it in your browser or a specific storage location. Just delete the information I mentioned and your problem will be solved. Pick up your mobile phone and delete it according to my inference ~ ~ ~
