The rollout of RCS on iMessage has been confusing to me. I know some carriers like Mint don’t yet support iMessage RCS; the company’s founder has said that it’s something on their end that will be fixed around December. But I’ve also seen some people on Apple’s forums pointing fingers at Apple.
I want to get a better understanding of what the holdup is. How does the iMessage RCS bridge work? What are the technical challenges? Why was every carrier not working on this for months and prepared for the iOS 18 rollout? And if I’m using Google Messages on an MVNO that doesn’t yet support iMessage RCS, does that imply I can’t RCS message an iPhone user on a carrier that does support it?
If people from Mint are saying it’s on their end why wouldn’t you believe them?
You’re not owed the technical details. If you want to encourage/pressure them, contact Mint support. They’ve already said that it’s a priority.
You can use RCS to message anyone on a carrier that supports it for their device from a carrier that supports it as long as you both have it enabled. There is a setting on your phone to turn it on. Consult the documentation for your carrier/device.
