Anybody problems with roaming on FP3+?

FP3 has been having problems with connecting to networks abroad/roaming. It seems a persistent and very irritating problem. Does anybody have the same issue?

Did you set the permission right to use abroad with your provider?

Yes, got an international sim. Called vodafone today, who saw that there was an error in the phone reading the sim network settings. Suggested removing sim. Did not work.
