If you insert non-Sprint simcard into LG G6 with LS993 model, it will say Invalid simcard, it means LG G6 LS993 need be unlocked, my service can help you to unlock GSM networks for LG G6 Sprint. I confirm after LG G6 Sprint is unlocked by my services, you can use any GSM simcards and of course, it's unlocked permanently.
