This happens on unlocked phones too. My Galaxy S21 has apps installed on it whenever I have a different provider (Trafcone, AT&T, etc.). It’s not just when it’s a phone resold from the provider.

Samsung allowing this to happen is bad though

I see Wiktionary, I upvote. As a linguistics student I hail Wiktionary as a God, the etymologies and some of the IPA transcriptions have done a lot for me
