That's because you are all "logged in" a RCS group. It's a nice solution altough not crypted on iPhone yet, but it's unavailable to a custom android rom because Google won't allow it without installing Google Apps.
Android Custom Rom = sms/mms(no group) or Signal (good luck making family adopt it) or Whatsapp (evil).
Except group chat. And RCS couldn’t be installed on a custom rom as Google took over the protocol and locked user.
Message is the only thing preventing me to switch of iPhone, as lineage or graphene will require installing WhatsApp, which is a big No.
I'm in group chats with android users and it works fine. "10729287 liked $message" is about the only difference as far as I can tell.
