About Samsung Galaxy S21 FE 5G

The Samsung Galaxy S21 FE 5G measures 74.5 by 155.7 by 7.9 millimetres and tips the scales at 177 grammes, offering a compact yet substantial feel in the hand. Its front is dominated by a 6.41‑inch AM‑OLED panel that delivers Full HD+ resolution at 1080 by 2340 pixels, providing vivid colours and sharp detail for everyday use. The device accommodates a single SIM card, keeping the tray straightforward for users who prefer one line of service.

Under the hood, the phone runs Google Android 12 with Samsung’s One UI overlay, paired with 8 gigabytes of RAM to keep multitasking smooth. Power comes from a 4500‑milliampere‑hour battery that supports wired charging at up to 15 watts, allowing a reasonable top‑up time when plugged in. As the model name suggests, the handset is 5G‑capable, giving access to the next‑generation mobile network where available.

This variant

This US‑specific model (SM‑G990U) adds mmWave 5G support through its UW TD‑LTE designation, while the base description only notes generic 5G capability. It ships with 128 GB of internal storage and 6 GB of RAM, whereas the base model’s description cites 8 GB of RAM and does not specify a storage capacity. The handset is offered in AT&T‑branded (SM‑G990A) and unlocked (SM‑G990U2) editions, keeping the same single‑SIM tray as the base model.

Compared with other listed variants, this version stands out by combining a relatively modest 128 GB/6 GB configuration with a single‑SIM slot in the US market—many US alternatives such as the SM‑G990U with 256 GB/8 GB RAM, the dual‑SIM SM‑G990U1 models, or the carrier‑specific SM‑G990V (Verizon) and SM‑G990T (T‑Mobile) models provide higher storage, more RAM, or dual‑SIM flexibility. It also differs from global (SM‑G990B/DS), Korean (SM‑G990N), Canadian (SM‑G990W) and Asian‑Pacific models by being a US‑only mmWave variant.
