Dear Samasung Team,
I bought Samsung S8+ when i was living in Korea then i moved to UAE and i am using local network provider and i am trying to connect to 4G but it gives me this messages "Giga LTE cannot be turned on wile a Non-KT USIM card is inserted.insert a KT USIM card and try again"
How to fix that issue with software as i my mobile data is very slow and only gives me Edge speed.
I need your support.
Thanks and regards.
