Not to worry too much. I will reset the settings and report back how it goes. One thing is apparent: There are two partially different MMS settings for Saunalahti customers depending on the SIM-card. Newer sim cards (I belong to this group), should use different proxy and MMSC.

So I try to sort out the settings, update wiki settings page accordingly if needed, and report back.

I think I can provide debug information as well if it comes to that.
