IPhone users have a weird obsession with Blue bubbles. The rest of us find it childish and annoying. They refuse to use any messenger other than iMessage.
I have a friend, not currently on iPhone, who was having trouble with SMS (note that SMS has a known message failure rate of about 10%+). He refused to switch to another messaging app, doesn’t want to have multiple places to message from. 🤦♂️
This is the mindset of iMessage obsessors. Frankly I see it as pretty juvenile. They don’t want to put effort into solving a problem.
This same person always has dozens of notifications sitting in the notification shade. Stuff you just don’t need to see, that Android lets you silence. Or just app notifications. Well no wonder he doesn’t want another messenger, with that much garbage he wouldn’t know he got a new message.
