I moved from the US to another country. I still have the same number, its just in airplane mode all the time since I have wifi pretty much everywhere.

However, iMessages in some groups have stopped (showing as green). It still works for individual messages and a few groups. But in some groups, it has stopped. Is there a fix to this? I can't seem to find any solution! This is the case across all my apple devices–iPhone 13, MacBook Pro and iPad.

Thank you in advance!

Green is not imessage that mean group MMS, you will need to get off airplane mode in order to send the message.
