The inbox of a mobile phone can be stored in a straw box.

Mobile phone inbox can't be stored directly in the straw box. The inbox of a mobile phone is generally used to receive and store messages such as short messages and multimedia messages, while the draft box is used to store messages such as short messages, multimedia messages or emails that users have edited but have not sent. These two functions are generally separated on the mobile phone, and the inbox will not exist directly in the draft box. When you receive new SMS or MMS, your phone will be automatically stored in your inbox, so you can check these messages at any time. If you want to save the unsent message as a draft, you can enter the SMS editing interface and select Save to the draft box after writing the content. The draft box is an independent folder, which is used to save the draft box information and can be modified and sent later.
