As a previous 10+ year iPhone user, finding a decent messaging app has been quite difficult to say the least. Going back to SMS from iMessage is a HUGE step backward. 90% of my contacts are iPhone users, and getting all of them to download Signal just to talk to me isn't a viable option.
I know RCS works with iMessage however it seems like Google Messages is the only app for this, and wouldn't that contradict a huge reason for switching to Graphene? Having to use sandboxed Play store already felt almost like a step backward. Also Google Message to iMessage doesn't even get encrypted from what I understand.
I purchased an old Mac Mini to run BlueBubbles for iMessage, which works decently. However turns out that associating your phone number is a huge PITA with SIM card swapping and such. So I either have to deal with that or get all of my contacts to add my apple ID email to the contact record they have for me. Also the messages have to temporarily get stored on Google's Firebase database so still not an ideal solution.
Can somebody please provide some input on this? What's your messaging situation look like?
