I’m pretty ticked it isn’t on Mint mobile yet. So much so that I plan on switching if they don’t have it when my year is up in a couple of months (after being a customer for 6+ years).

In fact, Mint Mobile revealed months ago on Reddit that it should have support for RCS sometime between December and Q2 of 2025. Ultra Mobile is also expected to see support around the same time.

As we reported last month, the second beta of iOS 18 released to developers has finally enabled RCS messaging support on the iPhone – but only for some US mobile carriers. Now with iOS 18 beta 3 ...

For example, Verizon, AT&T and T-Mobile all support RCS on iPhones running iOS 18. If your iPhone is running iOS 18.2, here are all the US carriers that support RCS on iPhone.

Xfinity Mobile The list is rounded out by Boost Mobile, which isn't listed for RCS support but it does support the standard, as long as you have an iPhone XS/XR or later with iOS 18.2 installed.

This includes both Mint Mobile and Ultra Mobile. Both these carriers were acquired by T-Mobile earlier this year. This means that if T-Mobile supports RCS on iPhone, these carriers should too.

It’s great that we have RCS finally on the iPhone, but there’s still room for improvement. Currently, RCS between Android and iPhone does not have end-to-end encryption (E2EE), which is a bummer.
