Default [Q] Save contact to SimCard

yeah, i know there are many threads about this topic, below is some of things need clarification and some questions
and just recently paid my attention on this "Contacts" thinggy, and realise that i have tons of duplicate in my Gmail (why the fack its synced to Gmail?)

need clarification:
-so, does newer devices cant save contact directly to SIM?
-we can only use "Export to storage", but that is in vcf (or some format)
-in order to copy all contact from phone to SIM, we must use an app in Playstore (how useful is this app anyway?)
-the contacts in SIM need to be exported to phone

question:
-why do you all think that theres no "Export to SIM" support?
-if i save a contact, does it automatically saved in phone? does it sync to elsewhere? (i dont like this sync-y thinggy)
-what is "phone only, unsynced", does it referred to the phone memory and if i saved a contact it will be in phone?

yes, im asking on how to configure about saving a contact and its relevant question
and sorry if some part is messed up, i got big event next week and kinda nervous about it
