5G on AT&T with Unlocked - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Has anyone successfully connected to a 5G network on an unlocked S20 variant on AT&T?

Yeah, I was able to no problem, just took a few minutes longer than getting an LTE connection. Got VOLTE as well, but no wifi calling/wifi texting is annoying.

Can't make or receive calls Verizon LG G4 on Ultra Mobile (T-Mobile MVNO)

A friend of mine asked me for help on his Verizon G4. He is using it with Ultra Mobile a T-Mobile mvno. A few days ago, he said he noticed he couldn't make or receive calls. I got the phone today. The phone has a Signal Bar with an x. I did a soft reset and also tested the Sim in a Galaxy S3. I could make and receive calls with the sim in the S3. I have an ATT sim and tested that in the phone, it received a signal and I could place a test call. What am I missing? Any help would be appreciated. Thanks.
Do you know which LTE bands and frequencies the mvno uses? Verizon had LG block a lot of bands on the VS986, so even though it's unlocked, it can't connect to their network. Pretty shady on VZ's part

I'll have to check. But it was working for a couple of months, up until yesterday.

unlocked S20 Ultra 5G cannot select 5G?

Good evening all,
I recently purchased an unlocked snapdragon S20 Ultra 5G and I am unable to get the Network Mode option under Mobile Network. Is there any way I can enable without having to wipe the phone?
I am currently on AT&T and in the LA area where 5G is available (I checked on the map)
Thank you!

In order for me to have wifi calling and 5G I had be running ATE6 U CSC from G988US.

Thank you for your reply!
I went ahead and followed the tutorial again and no success..
I am getting 5Ge which is not true 5G just a little gimmick AT&T has pulled. Notice in the screen shot how it says LTE still.
And I still don't have the option to select the network mode.. Which leads me to believe that that is what is blocking 5G from happening.
I'm currently in the Modesto area which according to the AT&T website should be one of the few cities to have it here in California..
I'm beginning to think this Snapdragon version I purchased has the band locked for some reason...
I have found out why I wasn't receiving 5G, my AT&T plan had to be set up with AT&T Elite or AT&T Extra plan. Without that I wasn't able to access the 5G network. It's a little mind-boggling that we have to pay extra to access 5G.

Paying extra for 5G is pretty standard. Besides having faster download speeds, what advantage(s) do you have over 4G, receiving a text or email 3 seconds sooner? I'm holding off until networks are built out and Service Provider standards are defined. In the future when more 5G utilities are widely available it makes perfect sense but for now I can't justify spending more for a 5G Device and additional Service Provider fees.

Verizon Low band 5G on unlocked S20+

Since Verizon "Turned on" their 5G with an update version BTJ1, I have yet to see a 5G signal on my phone.
So I guess my question is will that Verizon update be also sent out by Samsung in I hope BTJ2?
Can anyone confirm 5G working on Verizon with an unlocked phone?
Any movement on this?

5G not connecting with S20 from HK in the UK with EE

Recently upgraded my EE contract to 5G and am unable to connect my S20 5G phone to 5G, everything else works completely (samsung pay, 4g, 3g, 2g) and 5G is supposed to work due to network band compatibility as attested by others on reddit.
I have tried several times to test 5G by going to 5G areas in London but to no avail, when I am in network mode 5g/4g/3g the max I get is 4g+. I have even changed my sim card and recgecked my contract is indeed 5G. I am really not sure why this is happening. Please can someone help.
P.S. I have even tried using sim card slot 2 as some on other forums did and it still doesn't connect to 5g. I can confirm that 5g works with Vodafone so it definitely isn't a problem with the phone. EE customer service are useless.

Sudden LTE issues with unlocked T-835N

I've been using the Tab S4 unlocked korean 6gb ram 256gb storage version for years now on Tmobiles LTE network. The past month or so it doesnt want to connect to LTE. It will usually if I reset the network connections but then I lose my Bluetooth and wifi which is annoying. I tried replacing the sim card, calling tmobile, factory reset. It was on LTE for hours today and then went to the E which is 2g I assume. Im still on android 8. Anyone else experience issues lately on Tmo network? My unlock international S10 still works no problem on LTE.
