In iOS 18, Apple integrated support for RCS messaging, a new way that improves the texting experience between iPhone and Android users. Unlike SMS, you can see read/delivered receipts, send larger files, and have typing indicators, features that were previously missing.

Initially, only the big three carriers supported RCS messaging, while now other carriers also joined in supporting RCS messaging.

Some noteworthy exceptions from the list are Mint Mobile and Ultra Mobile, which have around 3 million subscribers in the US.

Mint Mobile and Ultra Mobile are specifically interesting, as they were both acquired by T-Mobile earlier this year, but seemingly T-Mobile hasn’t yet gotten around to supporting the feature on its new sub-brands.
