I have been trying to get FFMS working for some time now without sucess, I am on Vodafone UK and my settings are:

Access Point Name: Vodafone MMS
MMSC: http://mms.vodafone.co.uk?servlets/mms
Use Name: wap
Password: user
HTTP Proxy: 212.183.137.12
Port Number: 8799
Advanced Settings: 0.0.0.0 in all
Resize To: Medium
Network Mode: Polite, Havoc or Rude

None seems to work, some posts say that FAPN needs to be also used.

Any help would be appreciated.
