TLDR Review: Galaxy S21 Ultra 5G
Verdict
If you want the pinnacle of Android smartphone technology in 2021—top-tier camera performance, a stunning 120Hz OLED display, powerhouse Snapdragon 888 CPU, and nifty extras like S Pen support and DeX mode—the Samsung Galaxy S21 Ultra 5G delivers it all with style and substance. Just be ready to pay a premium for the privilege, and note that the 128GB base storage and lack of charger might be dealbreakers for some. Also, if you’re outside the US, especially in France, double-check network compatibility before buying, as this US version has limitations abroad. For a similar powerhouse that might suit international users better or lower your initial spend, keep an eye out for newer Galaxy S models or competitors, but for Android enthusiasts craving the “Ultra” experience, this phone stands tall.

Cons
- •The hefty price tag of $1499 means this phone isn’t for the faint of wallet — it’s a serious investment.

- •The US version has notable limitations for international users—it does not support 5G networks in France, may have GPS issues, and is limited to single SIM plus eSIM functionality.

- •While the battery life is strong, running the phone at max resolution and 120Hz refresh rate can drain it faster.
