Beautiful phone. Loved the new camera. I am a new Samsung user so having to purchase the charging dock and type C headphones separately was a bummer.
See below some important details:
Model:
US version: SM-G988U1 (unlocked for GSM and CDMA)
International version: SM-G988B/DS (Supports only GSM)
Hardware differences:
Processor:
US version: Snapdragon
International version: Exynos
SIM Trays:
US version: Single SIM tray
International version: Dual SIM tray + supports eSIM
5G is not working for me with T-Mobile (SIM1), and AT&T (SIM2). I still like this phone with 4G connectivity and 4G+, which is same as the 4G-LTE support.
Here is why 5G isn't working in the USA on the international version...
SM-G988B/DS' supported 5G bands
SA/NSA/Sub6 (n1, n3, n5, n7, n8, n28, n40, n77, n78)
T-Mobile's 5G Bands:
n71 (600 MHz)
n41 (2.5 GHz)
n260 (39 GHz)
AT&T's 5G Bands:
n260 39GHz mmWave
n5 850MHz Low-band... I believe this frequency is not used
I'm giving 4-stars out of 5 because 5G isn't working.
Sorry for the long post. Hope this helps some potential buyers in making a decision.
