I was very skeptical about this. But I was desperate. My new phone was just a cheap phone that came with my carrier. It won't get a signal anywhere. And the few times it did was on WiFi calling which kept cutting out and dropping the call. So I wanted to use my Samsung S9+ from AT&T with my new carrier T-Mobile. It took about 3 days and my code came. I was still worried the code would somehow mess my phone up. But I'm so happy to announce that my phone is now unlocked and everything works great. it was so easy. My husband can't wait for me to unlock his phone.
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
