If i buy an unlocked note 9 from samsung will I receive firmware and OS updates from T-mobile or does phone have to be a T-mobile note9?
If you've ported over from another carrier, we recommend that you update to the latest software version prior to making the switch. Afterwards, the updates from T-Mobile should come through like they do on our branded devices.
