I bought the Unicom number of Xiaomi 1s mobile phone. Why can't I receive MMS? Download failed, set. Can't ask experts to answer.

Hello! Please try the following methods:

① Before retrying, you need to turn on the data stream or switch.

② If you still can't send MMS, you can back up the factory settings instead of trying to back it up.

③ Require sim card operators to reset MMS access points.

(4) Still no good. It is recommended that you upgrade to the latest development version with a wire brush, and don't get root permission and install system security software for the time being. Try to solve it. You can refer to the following brush tutorial: A. First, you download a newly developed brush package from Xiaomi official website. This is the link:/topic-mirom.html.

B. During downloading, please back up data, enter recovery (shutdown, press and hold the volume increase+power on key to enter recovery), and clear the cache, user data and all data. Install the driver on the computer and download a miflash brush tool. This is the driver installation link:/thread-504332-1-1.html.
