Samsung Galaxy S21 5G Model Number SM-G991* Differences

Updated on Jan 20, 2021 by Tuan Do

Samsung announced their new flagship smartphones early during its Unpacked event in January 2021. The three new phones become more appealing to customers since they all have new features, updates, and refinements while the starting prices dropped by $200. The Galaxy S21 5G is the most affordable option with prices starting from just $799 for the 128GB storage option.

Samsung managed to lower the prices thanks to lower-cost component; They also remove the charger, wired headphones, microSD card slot, and reduce RAM capacity from 12GB to 8GB. Since the phone was launched during a pandemic, many people would appreciate the price drop and consider the upgrade. Despite being the cheapest version, Galaxy S21 is still powered by the latest Qualcomm Snapdragon 888 or Samsung Exynos 2100 SoC, depending on your region.

As compared to the S21+, the S21 has a few minor trade-offs; For instance, it uses a polycarbonate instead of Gorilla Glass Victus, a smaller 6.2″ display, a smaller 4,000mAh battery, and no Ultra-wideband (UWB) support. Other specs are pretty much the same as the S21 features a FHD+ Dynamic AMOLED 2X flat display with HDR10+ and 120Hz variable refresh rate, an ultrasonic in-display fingerprint scanner, 128GB/256GB of internal storage, and a triple rear camera setup including a 12MP main sensor, 12MP ultra-wide sensor, and a 64MP telephoto sensor.

Unlike previous years, there is no cheaper 4G-only model. All S21 models support 5G and they cover both Sub6 and mmWave networks.

There are a lot of model numbers of the Samsung Galaxy S21 5G on the market but all of them start with SM-G991. The following characters help us identify exactly its region, carrier, processor, color, storage, LTE and 5G bands. To find out all the differences, you can check the comparison table below.

    SM-G991U1 is the version of the Samsung Galaxy S21 listed on their website, but it is back ordered. I am wondering. They do not have 5g yet. Will a Samsung Galaxy S21 SM-G991U1 on both 5G and non-5G?

    Does anyone know if the UK spec Galaxy S21 5G support 2 physical SIMS (like the S10 hybrid)?
    If so what is the model number for this variant?
