## Customer Reviews

### ⭐⭐⭐⭐⭐ Just as described
*by D***  on May 28, 2024*

Brand new and working good so far. No issues. Physical Dual sim as stated.

### ⭐⭐⭐⭐ Good
*by D***Y on November 18, 2022*

The battery life sucks but picture quality is great. Wasn't reading my fingerprints could be because of the tempered glass. Overall it's not bad.

### ⭐⭐⭐⭐⭐ Indeed dual physical sim support
*by A***. on August 11, 2023*

I haven’t used the device yet. So this is an early review where I am glad that the delivered product aligned with the advertised details. This phone indeed supports dual physical sim cards (see screenshots). This is important for people outside the united states with no e-sim support.Some sellers falsely claim dual physical sim (G991B/DS) but they actually deliver G991U which supports only a single sim. So I am glad this seller delivered the right product.
