why won't my galaxy s3 update

my phone is still at 4.1.2, says service unavailable every time I try to update even when on Wi-Fi or full 4g, and isn't rooted, my dad's phone has updated to 4.3 with no problems

Welcome to AC.

Same carrier or network?

Even so, updates are not sent out to all phones of a particular type at the same time.
