I bought unlocked Samsung S8 from Samsung directly. Later i realize the services are not 100% working...and when communicated with AT&T they found Samsung S8 is not certified by them yet (as of 08/15/2017) and hence I might not be able to use fully. Another issue was AT&T online profile did not recognized my phone it registered as Unknown Device. So pls check ur carrier before buy it. If the issue is been fixed or not. Its August 2017 now and S8 was released in April 2017....too bad. almost half of the yr passed.
