sm-g988b/ds S20 Ultra 5G T-Mobile US - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Curious if anyone is using the sm-g988b/ds S20 Ultra 5G on T-Mobile US? If so, what is the LTE and if you're even able to get 5G. I believe this model is missing some of the Tmo US bands.

5G???

Does all the S20 series devices support 5G or anyone device will have the 5G support??
The Galaxy S20 Ultra is reported to be a 5G device. No mention yet if the lower priced models will offer 5G.

I don't think that every S20 series device will support 5G but any one or two models may have the 5G support.
Patent filings indicate that there will be 4G and 5G models of all three devices. 4G models will be sold only in countries with no immediate 5G infrastructure plans, however.

you just need to pay more for the 5G model
I hope there is a software switch that will allow us to turn 5G off for those of us who do not live in a 5G coverage area. Not all of us live in major metropolitan areas.

S20 5G SM-G981B/DS Does it support mmWave?

Samsung technical expert on chat said yes,
the modem the phone has seems to indicate it does (unless samsung disable something on the S20 5G specifically to limit it to Sub6 bands only),
https://www.samsung.com/semiconductor/minisite/exynos/products/modemrf/exynos-modem-5123/
this webite seems to say no (no mmWave bands listed),
https://www.devicespecifications.com/en/model/f3e652f5
to add to my confusion the verison S20 5G originally didn't support mmWave until they released the S20 5G UW
I'm in the UK on EE. I just would like to know if the phone can or can't receive mmWave if it was transmitted to it?

I think you're out of luck if you didn't purchase the 5G UW. There is no modem technology currently available that can leverage 5G signals in the sub-6 GHz spectrum and 5G signals in the mmWave spectrum at the same time. You can only get one or the other.

Not so, Verizon released 5G mmWave for the S20, Plus and Ultra devices on June 4th. They're labeled as S20 5G UW Models, other carriers to follow. A couple of drawbacks for the S20 Base Model, you're limited to 8GB of RAM and no MicroSD.

Chinese or Korean s20 (98xN or 98x0) in the US?

Is anyone using a Korean or Chinese s20 in the US? If so, what carrier are you using, and do you have any issues? I know 5g probably won't work, but other than that, any problems with service on these phones?
To answer my own question, the s20 Ultra Korean model (S988N) with KOO csc works perfectly in the US on Verizon and Tmobile, including 5G.

Question Galaxy s22 Ultra (S908U1)

I bought my s22 ultra (S908U1) from United States and now I'm in my home country but I lost the 5G network because the only bands available here is n77 and n78 and I tried to enable them in my device but I can't. Anyone can help me with that?

Question Unlock 5G for imported S22 Ultra

Hi folks,
I am not able to get 5G on my Samsung S22 Ultra here in India, which was imported from UK, so has the Exynos 2200 chipset. Although it supports all the 5G network bands required here, for some reason it does not switch to 5G.
Could you guys help me out. Is there any way to unlock the device or something.
Thanks
Me too
Any way to connect 5G.
