2. The local GPRS signal quality of your mobile phone was not good at that time, which made it impossible to receive this multimedia message.
The multimedia message you want to download is too big. If it is 200K, it exceeds the size supported by your mobile phone. If your mobile phone only supports less than 100K, the MMS download will fail.
You can receive a small MMS spontaneously, such as a plain text MMS, and test whether you can receive MMS normally.
I hope it works for you. I wish you good health and smooth work.
