What country, region, or carrier, does the S21 model nr SM-G991UZAATTA represent? It’s not a typo. The last 3 letters are “TTA”.

Hi:
Can you tell the difference between models #SM-G991U and SM-G991Ui? The Samsung store told me the model ending in “U” is not unlocked but the “i” is?

I am considering to buy a Samsung S21 5G, unlocked to use with Verizon. Which model do you suggest so that I have the best and broadest band reception in the USA?

In reply to Paul Buttrey.

The G991UZVAXAA – is basically the model with the “V” representing Violet – but yes it does fall under the SM-G991U1 category (which designates its factory unlocked for use on any network).

In reply to Jody. Its in the list. Its the Canadian variant. I wouldn't buy for it for use on an American cell carrier.

I am considering buying a Samsung Galaxy S21 5G for use on Republic Wireless. It has to be unlocked. On various websites I have seen two different model numbers for this. They are SM-G991U1 and SM-G991UZVAXAA. Are they the same or different? If so, what is the difference? And why are they different? It is a little confusing.

You have some of your information wrong about the s21 or maybe it’s grammatically written in error, but the s21 has a plastic back panel made of (polycarbonate) while the front IS made from Corning’s Gorilla Glass Victus; just wanted to point that out.
