TL;DR
- Users who have rooted their phone, have their bootloader unlocked or are using some custom ROMs report that their RCS messages are not being sent, even though RCS shows them as connected.
- The Google Messages app does not show any error messages when blocking RCS messages of these users and does not send the messages out as SMS or MMS either.
- Google famously campaigned for Apple to include RCS messaging in iMessage but is now blocking it for certain Android users.
I was able to get RCS working again yesterday by updating to the latest version of Play Integrity Fix, but if that hadn’t worked, I would have disabled it and then probably switched over to Textra or Yatta for texting since RCS is basically the only thing keeping me on messages for texting.
I have it disabled anyways along with the Carrier Services app. Guess what: my battery life improved dramatically.
Carrier services isn’t required for RCS anymore pixel phones brand new don’t even have it installed.
