If it’s that important to them then get them an iPhone? But then they will just get bullied if their iPhone isn’t new enough so maybe the problem isn’t the bubble color after all but the bullying.
When RCS is implemented, even if the bubble color is still green, the rich media features being available is going to eliminate the pain points of messaging between platforms. The bullies might still bubble shame but everyone else will stop caring.
I just want another mini phone, it’s nice they are making them lighter but I want something I can use with one hand. Not a brick that’s been sliced slightly thinner. I want another iPhone mini with usb c and better battery life
