Android (AOSP) package
MmsService
Keep: com.android.mms.service Keep Vendor documentation
The background service that sends and downloads picture messages and group texts over the carrier network. Keep it: MmsService is needed for the phone, its updates or its security.
What it does
MmsService is the Android component that actually transmits MMS messages. When your messaging app sends a picture, a long text or a group message, it hands the message to this service, which connects through the carrier's MMS settings to send it, and incoming MMS are downloaded the same way. It runs only while an MMS is being sent or received.
If you disable it
Picture messages and many group texts fail to send or download; plain SMS and RCS chats keep working.
How to disable it
On most phones Settings greys out Disable for this package, so ADB is the way to turn it off. The commands below work without root and can be undone.
