By message, it can be any kind message (audio message, chat message, video message) except an SMS then? Because you seem to use more SMS than bericht for that specific situation.
Yeah, any sort of message really. We sometimes use it for sms too, but that is merely a matter of preference I think. If you just say 'bericht' it doesn't really specify where you got the message, so yes, use SMS unless you want to say 'he sent me a message on my phone', which makes you sounds like an old dork. Hardly anyone texts anymore over here, everyone uses Whatsapp, so we usually say: Ik app je vanavond! (I'll app you tonight)
