How to get rcs universal profile on any Android

1.) Enroll in Messages Beta and install

2.) Download Activity Launcher

3.) Clear the data of 'Carrier Services' and force stop 'Android Messages.' Edit: If you don't have 'Carrier Services' you can download it from the Play Store

4.)Open Activity Launcher

5.) Tap 'Recent Activities,' and in the menu choose 'All Activities.'

6.) Look for 'Messages'

7.) Tap it, then scroll until you find 'Set RCS Flags'

8.) After pressing it select 'ACS Url"' and in the menu select http://rcs-acs-prod-us.sandbox.google.com/

9.) Select OTP Pattern, and in the menu click, YourlsMessenger\sverification\scode\sis\sG-(\d {6}). Edit: This appears to not be staying for some. It didn't stick for me either but my RCS still activated

10.) Click Apply Edit: sometimes clicking apply won't take you anywhere. Just go back and check messages

11.) Follow setup in Messages. Will take around three minutes.

Install Google's messages app v 5.2 or later.

It works. Tested on MetroPCS Moto e5 play on os 8.0. The articles out there neglect to mention that you have to install Google carrier services beforehand.

Here's the official features list:

It will be nice when this has links to other messaging services, Airbnb, Uber, WhatsApp, Facebook, etc....

I wonder what the two other servers that are in the RCS drop-down menu (iot and jibe) are for.

Some benefits I can see with "universal profile" RCS over standard text messaging:
You can send attachments of any filetype with a maximum size of 105 megabytes.

You have the ability to delete multiple messages at once without deleting the whole conversation.
Being able to share Google Assistant results
It is a universal chat service that eventually every text app will embrace

Here's some enhancements the app could use:
1. Set profile pic for individuals and groups
2. Set profile name for individuals
3. Better graphical sent, delivery and read indicators
4. Ability to see if the other person is online in a 1 to 1 conversation
5. Ability to indicate which message is being replied on
6. Lacks group administration capabilities

A need for public links for groups and separate, invite-only private groups, and admin controls. Basically they need slack.
It lacks threaded replies
