Edit: NOTE, I am the receiver of the texts.
So many people asking me to have my wife do something different on her end.
Beloved, she is on iPhone because she doesn’t want to do anything “weird.” She is texting from her phone number using her texting app. That’s what’s going to happen.
Now, why can’t I get iMessage on my android phone? If it’s just a messenger app why not make it available for Android?
I’d use it.
SMS/MMS has really low file size limits, and iPhones may downscale a little more aggressively than required.
Just pick an internet based messaging service. I like Signal, but they all work.
The next version of iOS should add support for RCS which should allow for cross platform larger images as well.
Welcome to 2008, apple
To be far, apple has had iMessage since 2011 and no one cared about RCS until it was adopted on Android in 2019.
To be additionally fair, Android still has phones out there in use that still dont have the RCS feature, and never will because those phones are no longer supported.
The same is true of iPhones
