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.
The real reason: Apple intentionally doesn’t support the open protocols that send pics and videos to non-Apple devices. These protocols are a decade old and work great. They use a proprietary protocol instead, which they will not share with other phone manufacturers.
What the average iPhone user thinks: Apple is better than Android!
It’s pretty dumb.
The thing is, Apple phones do support these things, but only if they change the default messenger app, and most Apple users won’t do that. IPhone users are worse than Windows users when It comes to changing their default apps.
Unless I did a really poor job researching it, you cannot change your default SMS/MMS application on an iPhone.
You can use other messaging apps like Signal, Whatsapp, Telegram, or AIM. But if you want to use SMS, you have to use iMessage.
Maybe this is US-specific though. Europe often forces Apple to do things they don’t do here.
