Hello
I thought I could block 5G by selecting LTE only, but I see 5G in the top right corner.

What does this mean? Is there something I cannot block 5G?
Thanks!

if you go to settings>about phone>scroll down to "sim status" and tap it, you will see "NR NSA" in the "mobile data network type", this stands for new radio non standalone. it is essentially just upgraded 4g(fake 5g)
