Google’s initiative to bring RCS to every Android user has been a slow process, but it’s expanded quite a lot, even just in the past few months.

Today, T-Mobile has announced a partnership with Google to bring RCS to every Android user on T-Mobile and Metro.

The Universal Profile is the standard Google has been pushing for Android users for the past few years now, and T-Mobile is using that expertise to roll out compatibility to its entire network and making the implementation based on the Universal Profile, just like Google’s.

That means T-Mobile users will get RCS that works across networks, so long as those other networks do the same thing.

Currently, there are apparently 40 devices that work with RCS on T-Mobile and Metro under this new partnership, but T-Mobile “aims” to further expand that.

That’s a fancy way of saying that T-Mobile Android customers with capable smartphones get RCS with Android users on other networks, too.

Today, nearly 40 T-Mobile and Metro by T-Mobile smartphone models are ready to share RCS messages with Android users on other networks and T-Mobile is aiming to bring this capability to all RCS-enabled smartphones.

Based on T-Mobile’s press release, it sounds like Google Messages is a core part of this new strategy, but T-Mobile clarified to 9to5Google that this network rollout will work on the native messaging app on these smartphones.

We’re also curious what this means for the CCMI, an initiative from carriers including T-Mobile, Verizon, and AT&T, which was supposed to be delivering RCS to Android users this year!
