Jazztel Spain

[mebasa]

I'm a new Jazztel móvil (Spain) customer. Formerly I was a Movistar customer.

I have tried provider's recommended configuration, but, when I try to send MMS, it gives the following errors:

---------------------------------------------------------------
Possible incorrect mmsc setting.
Unexpected http response
(HTTP/1.1 504 Timeout in outgoing queue)
---------------------------------------------------------------

or also:

---------------------------------------------------------------
(HTTP/1.1. 400 Bad Request - server could not understand request)
---------------------------------------------------------------

Mi current configuration is:

---------------------------------------------------------------
MMSC: HTTP://jazztelmms.com:8081
Proxy: 217.18.32.183:8081
APN: jazzmms
USER: <blank>
PASSWORD: <blank>
---------------------------------------------------------------

I have also tried without port number in MMSC and/or in Proxy, but it doesn't work.

Provider's tech support says that MMS over iPhone is not supported by them. So I need help to make it work as when I was in Movistar.
