RCS: +1 4126829751
RCS is the platform for communicating with Android devices that has a cellular phone number. I had received RCS support with my carrier in April 2025, and since then – I am able to use RCS, and it has been validated with a person I communicate with. RCS has many of the same features as iMessage, and probably one of the reasons RCS was created to compete with iMessage.
No matter what Android phone you have, the standard Messages app should support RCS when using Android’s OS core. The only exception to this will likely be Graphene OS which takes out the Google components including RCS support within the Messages app. With this being said, Graphene OS will use SMS instead. One thing to note, RCS with Apple devices at time of writing this page is not supporting any form of encryption, but Apple is working with the GSMA for adding encryption in their version of RCS. While not terribly important – it is something that some people might want to consider.
