This guide will explain how to clear unread SMSs which cause the SMS section of your ZTE or ZLT MiFi's dashboard to be inaccessible. Whenever you try to open the SMS section, All you see is 'Waiting' with a spinner until you get logged out due to a timeout.

Although an easy fix is resetting the MiFi by inserting a pin into the reset hole, there are cases where you do not wish to do a reset or the SMSs remain even after a reset. The goal of this guide is to delete the SMS or reduce them to a number which would make the SMS section available once again.

This has been tested on the ZTE MF927U and the ZLT M30S using a Windows PC.

  10. Make a list of their IDs separated by %3B e.g IDs 100, 101, 102 and 103 would be 100%3B101%3B102%3B103

  11. The request body for the above example would look like

    Code:

    isTest=false&goformId=DELETE_SMS&msg_id=100%3B101%3B102%3B103%3B&notCallback=true

    Notice that the list of I.Ds are inserted between = and %3B&notCallback=true

  12. Get the number of characters in the request body using a website like https://www.charactercountonline.com/ . It's 81 in this example. Its value will be used as Content-Length in the SMS deletion request

  13. Get the request headers for POST requests by adding or deleting a contact in the phone book then clicking the output from the log (in green)
