Found it by myself. A setting was turned off on my phone when I switched the sim card. No clue why but I could only send or receive from an email address. I turned it back on and it is working correctly now.

Yes I have a data plan. I'm also connected to my wifi so there shouldn't be any problem. Cancelling every phone number is not an option. My imessages need to work normally.
