UPDATE: After everyone replied with what my intuition told me anyway, I got back onto Telstra and got a different agent to check again. The second agent then said
Upon checking your IMEI number the device is unlocked.
So I have no idea how the first agent stuffed that up. Thank you everyone! 2 hrs of my life wasted on what I assumed was the case in the first place.

Hey, I've gotten myself a bit confused and can't find an answer online.
I bought a Galaxy S21 Ultra 5G at JB Hi-Fi back in June 2021. When I bought this I went straight onto one of the Telstra plans to get the big JB Hi-Fi gift card. I am no longer on that plan, and am instead on a cheaper Telstra one.
I'm now going overseas in 2 weeks time, and purchased some overseas data sims, which prompted me to make sure my phone was unlocked.
When I contacted Telstra online, they said it wasn't unlocked. And have sent it to the team to get unlocked. They said this can take 7-10 business days - which is cutting it pretty fine for my trip.
However, during that conversation they mentioned prepaid a few times, which I found odd.
So I tried my housemates postpaid Sim in my phone, which is Kogan via Vodafone. And it worked. I was able to connect to 4G and use the internet.
So my question is this - Is my phone unlocked or not?
If I connected to Vodafone, sounds like it should be right? I wasn't sure if maybe the fact that the sim was postpaid, that maybe it would work anyway. And if I have a prepaid travel sim maybe it won't work.
Maybe that sounds silly to someone who knows what they're talking about, but I don't understand the process or how it works, so I can't problem solve it myself. And I don't really trust Telstra support on the matter.
pm me the imei and I can check on the network
