I'm using the samsung a32 5g.
Just wondering if it's worth allowing it to use my mobile data since I'm on a tight plan and why it would be important. All I use is SMS messages, I read that all it is used for is RCS or any android related messaging apps.
If that's the case can I disable background data usage if it does nothing for me, and even go further to disabling the app? Would doing so disrupt SMS or any other messaging service?
A first indicator of what this app does is it's package name: com.google.android.ims
IMS is usually the abbreviation of IP Multimedia Subsystem, which is dedicated to do communicate with the carrier over IP, instead of special protocols as this was in 2G/3G.
Another hint gives us the description in Play Store:
Carrier Services enables the latest communication services from mobile carriers, including battery-optimizations and support for enhanced features in the Android Messages app.
Therefore this package seems to implement the client side of "RCS Messaging", the successor of SMS.
I am not sure how many carriers already support RCS and how widely this is used. In general I would allow background usage, otherwise the app would be pretty useless if you every receive an RCS from someone (you never know who might send you something).
From my understanding plain SMS should not be processed by this app.
