Solution for Nokia e71 failing to receive MMS

The reason why the MMS cannot be received is that the MMS access point is not set correctly, because the MMS access point needs to fill in the Homepage Address.
You can turn on "information"-"option"-"set"-"Access Point used by MMS" to see if no access point is defined.

Solution for mobile users:
Choose "Tools"> "Settings"> "connection settings"> "Access Point" to check whether the Access Point cmwap exists.
If you do not have one, select "option"-"add Access Point" to create a new connection name: cmwap (you can name it as you like)
After creating a new access point, you need to define the following options. Other default settings:
Access Point name: cmwap
Home: http://mmsc.monternet.com
"Option"-"Advanced Settings"-"proxy server address": 10.0.0.172
Proxy port number: 80

Then, "information"-"option"-"set"-"Access Point used by MMS": cmwap
In this way, the access point for receiving mobile MMS is defined.

Solution for Unicom users:
China Unicom users set up MMS access points in a similar way as mobile users. I will not elaborate on them here.
Several options to be modified are as follows:
New connection name: uniwap
Access Point name: uniwap
Home: http://mmsc.myuni.com.cn
