Hi,
Finally, I managed to solve the MMS issue on my FP4 for french operator "Bouyges Telecom"!
After reading these post: https://forums.ubports.com/topic/10181/fp-4-without-mobile-data/4 and this one https://forums.ubports.com/topic/10464/how-to-fix-mms-issues, I gave it another try and found a working solution for both internet and SMS.
I did:
Delete all existing APN settings
Create a new APN setting with fields:
Internet and MMS
Name: Bouyges Telecom
acces: mms.bouygtel.com
MMSC: http://mms.bouyguestelecom.fr/mms/wapenc
And keep all other fields empty.
Here is the screenshots with french language:
