The rollout of Rich Communication Services (RCS) in the US and much of the world has been a slow affair. However, the next-generation replacement for SMS and MMS messaging just got a much-needed boost from T-Mobile and Google. The companies say they've partnered to make RCS messaging available to all T-Mobile and Metro by T-Mobile customers.
Following a more limited rollout in 2015 and an expansion in 2018, T-Mobile claims it's the first carrier to implement a full standards-based RCS interconnect with Google's Messages platform. If you're a subscriber who owns an Android device, you'll be able to take advantage of all the protocol’s features, including typing indicators and read receipts, when messaging Android users in other countries. Of course, the person you're chatting with will still need to own a compatible device and pay for service from a carrier that supports the protocol.
