Question S9 on 3 locked to network

[Lewie]

I was given an S9 by a mate - was on 3 by t when I popped my Tesco sim it appears network locked
I thought 3 had supplied unlocked phones for some time -
Any thoughts - am I doing something wrong

You sure it's a 3UK phone? Their phones have been unlocked for a number of years.
