I think it used wifi to send out my mms.i have tried like this

 ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
connMgr.startUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE,
                "enableMMS");

MMS sending connectivity issues when wifi is active (Android)

But the issue is still on, Please give me some help...

I have fixed the issue. Before send the mms when wifi is on, first you should call this method:

ConnectivityManager.startUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE,"enableMMS");

When the connection is active, you need to call this method:

ConnectivityManager.requestRouteToHost(ConnectivityManager.TYPE_MOBILE_MMS,PROXY);

If it returns true ,you can send out the mms sucessful.

I had a similar issue, it would seem that it may be related to the use of AndroidHttpClient (in HttpUtils). Replacing it with DefaultHttpClient did the trick for me.
