omacp = OMA Client Provisioning. A protocol specified by the Open Mobile Alliance (OMA).
Configuration messages parser. Used for provisioning APN settings to devices via SMS.
In my case, it was automatic and I never needed configuration messages.
Maybe it’s useful if carriers change their APN. But you can still change the config manually, it’s not difficult.
Dunno why Mediatek handles this kind of things. Safe to remove. At worst, you’ll need to manually config your APN.
OMACP can be abused.
