Smart call and other Samsung features?

I've been combing the forums and I haven't been able to find an answer to my question, sorry if it's been posted before and I didn't see it.
So I'm making the switch from a Verizon Galaxy S8+ to an AT&T Note 8. I know Verizon blocked a bunch of Samsung features and I wanted to know if they're available on the AT&T variant? My Note 8 won't be delivered until 10/18 so I'm just preparing myself. Lol
Features I really want:
-Smart Call (I know this is deactivated on almost every carrier)
-Samsung Cloud
-Device Maintenance
Does the AT&T dialer have the nearby places feature? I haven't been able to tell from any videos I've found and I haven't been able to go into a carrier store to see a demo unit.
I was able to get all of these features on my Verizon S8+ by flashing the regular U1 software, but I lost all of the Verizon features I needed (Visual Voicemail, WiFi Calling, and carrier billing for Play Store). So i'm wondering if it would be worth it for the Note 8? Or are the features I'm inquiring about enabled on the AT&T variant?
I saw some people were saying they were having LTE and WiFi calling issues with unlocked devices on AT&T so I'm a little weary of flashing the unlocked version onto it.
Thanks in advance!

Samsung Cloud and device maintenance are both on AT&T.
Not sure what smart call is.

Awesome! 2 out of 3 features is good.
Basically just the Caller ID feature built-in by Samsung. I doubt it would make the cut as carriers usually charge for it as a premium service and they don't want Samsung to provide it for free.
It also adds a "Places" section in the stock dialer. I know that specific feature was also available in the T-Mobile S8+ when i had it briefly, but for some reason was removed by Verizon.

Looks like it has nearby places as well even though I've never used it.

Awesome. So it has the feature, it's just probably stripped down. Probably can be activated by flashing the unlocked software on it down the road.
Thanks for checking!

Smart Call feature is not available on the AT&T Note 8.
Looks cool too.

I flashed the unlocked firmware on my AT&T Note8 and Smart call is working on it. Didn't realize how much I got Spam numbers until I didnt have it. I'm glad I flashed the unlocked firmware to get it.

That's what i think i'm going to do. And i didn't realize exactly how much bloatware is on the AT&T version so i'll be flashing the unlocked version on it today.
Did you flash the regular, unbranded one or the AT&T version? Which features did you lose?

I flashed the regular, unbranded version. Only thing I noticed I lost was Wi-Fi Calling and VoLTE which I can live with. Didn't realized there was an Unlocked AT&T version of the firmware, might give that a go but I've got my phone set up perfect enough that I might be too lazy to do that hahhaha.

Oh nice. I've got really crappy service inside my house, so I need the WiFi calling. I think i'll give it a try later today and see if it still has the features i need.

I have the same crap coverage in my house too. So i use Wi-Fi Calling all the time. There is the AT&T Call Protect app that in essence does the exact same thing as the Smart Call (I'm using that too)

True, I saw that's it's powered by Hiya, which is the same app for the smart call. Mine just doesn't seem to be working. I've gotten 3 spam calls already and that app hasn't shown anything. AT&T should just let that service go and use the built in Smart Call lol
For now, I just installed the actual Hiya app so i can get a popup along with the call to see who's calling. Gonna just flash the AT&T version of the unlocked software!

Yeah, AT&T's Call Protect never worked for me either.

Where can i find the unlocked att firmware?

Call protect is working for me. The other day I had a random number call and it labeled it as a telemarketer right by the number. From there you can block the number from ever calling again and additionally it is automatically setup to block potential fraud calls.

AT&T Call Protect has been working for me too, I have been getting a ton of calls and it always labels them as potential fraud and auto blocks it and i also get them labeled as telemarketer a lot.

S9+ Exynos on T-Mobile US Journey.

Just received my S9+ 256GB Korean Variant SM-G965N. This is going to be my experience with this particular variant and its compatibility with the T-Mobile network. Currently it shows I'm connected to Band 2 LTE but the speeds I'm my area are very slow. Withing the next couple days I'm am going to test the network throughout my area in Cali and test speeds and connectivity and report back. Unfortunately the build of Samsung pay is customized for S.korea only and not compatible here in the US.
Current build after first update is G965NKOU1ARC7
Baseband versions G965NKOU1ARC4

I have some data speeds this afternoon while out driving. The long screenshot is from my G965 and the short list of from a T-Mobile variant S7 . Connection to the network itself has been stable with no notice of dead spots or issues switching towers, if anything I'd say the switch is faster from what I've notice between devices.

Excellent...a lot of us have been waiting for this...thanks for testing...

I was curious about this. I have a G965U1(S9+ Unlocked North America variant).
I have a second phone with Ting GSM(T-Mobile), and I tried a few speed test. The phone configured it self to send calls over wifi when ever I connect to wifi. I found that peering with Sprint appears to be an issue.

Hey guys,
I also got an international S9+ (SM-G965F) but from Germany Unlocked (DBT). So far the signal seems to be great. Will post some Speedtests later. The only downside is that wifi calling and VoLTE is not there. It was working with my German sim. Other than that it's been great.

Have you flashed T-Mobile CSC? I assume you have to root and make a custom zip to flash the files. If the phone thinks it's a legitimate T-Mobile phone then it give you full speeds.
Also is the Korean phone a duos? Dual SIM?

I dont think that is possible. Isn't the Korean version run on Exynos? Flashing a Snapdragon CSC for TMB would be wonderful but I think would mess lots of thinks up. Hopefully someone will be able to change the CSC to work on the exynos processor.

Okay so the weirdest thing happened to me. I tried to use Samsung pay a few days ago. I used app cloner to copy the working version of my note 8 snapdragon and sent it to my S9+. It didn't work and gave me the connection error. Now I was just on the phone and out of boredom I tried to open Samsung pay again while on the phone and it magically worked. It asked me for my Iris and fingerprint and I was able to add my cards again. Again, this is on exynos DBT from Germany without any modifications or OEM unlock.
Hope this will help at least with Samsung pay.

Yes am looking into seeing how I can configure the CSC to achieve full T-Mobile speeds. The Korean variant in not a duos.

I have a friend that works at Sammy S. Korea that picked it up for me, as for Samsung pay the apk is specifically built for the Korean market and has a different activation process which requires a text from one of the local carrier networks which I cant bypass.

The build is completely different and won't work because of the region and coding in this software build. I am not ready to root yet so I'm going to tinker with software that's official and see what I can get working, improve on for now.

Not really. I'm also on T-Mobile USA and have the German exynos. The apn settings were loaded correctly. Maybe check them in the settings and make sure it's set correctly. The only thing that is not working is VoLTE and wifi calling.
Samsung pay finally works with the credit cards but the membership doesn't work.

ow did you do the initial setup with or without the T-Mobile sim inserted ? I noticed when I originally set my Korean variant up without the sim, for some reason I did not connect to LTE in my area and after oem unlock and restart/ full wipe it connected perfectly since.

I've got the same model, I'm with ATT, speed test shows 31m down and 10m up, but actual downland from play store is less than 2m...

Hi do you receive benefits in your samsung members app?

Yes if we can get T-Mobile CSC settings to enable VoLTE and Wifi calling then I will root.
I am recently realizing Samsung Pay is not everything it's cracked up to be. It doesn't seem like they have many 3rd party companies registered, so I made a custom loyalty with the barcode, but it doesn't work when it's scanned at checkout. Funnily enough, I have the loyalty in GPay as well, and it works just fine. Also SPay doesn't seem to work in gas station cc readers where you stick the card in and pull it out instead of swipe. Unfortunately it just doesn't seem like the technology is there yet where we can ditch traditional cards.

Unlocked on T-Mobile

Hi!
Hey any functionality lost by using the unlocked version on T-Mobile ?
Thanks

When speaking to Samsung about this, they told me all T-Mobile bands are supported including 5G on the unlocked versions. What you may lose is video calling (who cares) and possibly wifi calling. But in the past I've seen threads were talking to higher-level techs at T-Mobile can enable those features.

I noticed Samsung checkout page didn't ask if you need a SIM for the unlocked phone. In the past it would give you an option. So curious if you will need to go to the store for a SIM.

Thanks . Video calling is big with me . Rats

My Note 9 was unlocked from Samsung but video calling and Wi-Fi calling work fine. Not sure about this phone though.

Won't you just be able to flash the T-Mobile firmware via Odin if you get the unlocked? Then you get the best of both worlds. This is what I did with my Note10+. Got the Unlocked from Samsung then used Odin to get the official T-mobile firmware.

i had an unlocked note 10 + on tmo and had no issues with video calls or wifi calling. i got from the samsung site that the note 20 has an esim which i would guess is why you dont see any wording for a conventional sim...

I currently use an unlocked note 10+ on tmo that isn't flashed. The only limitation is that I cannot do tmo-to-tmo video calling. It may simply be a setting on my end but I never looked into it as there are so many options. Everything else works fine and I seem to get every update at the same time.

Thanks. I haven't flashed a rom before but there's lots of info available. If I don't upgrade to the Note 20 then I will flash the TMobile rom onto the Note 10+. If I do upgrade I will eventually flash the Note 20.

TMO user with S20 Ultra here. Don't use video calling so I could not say. Wifi calling works.
Third party VVM apps do NOT work and TMO's downloadable visual voice mail app is garbage IMHO.
When I put my VZW sim in the same phone the Samsung VVM app works beautifully.
Unlocked S20 Ultra 512GB here.
"5G" works on TMO where there is coverage however the speed tests show LTE as connection type. Interestingly enough some of the speed tests actually show 5G. Not sure what's going on with that. Have reached over 200Mbps down on TMO "5G" a few times. Most of the time it's the same speed as LTE. Don't care, it works, hot spot works nice too.
If you were to (properly) flash TMO firmware (in theory) it SHOULD make your phone just like a TMO bought phone including the cheesy jingle when booting up. Never tried it, I like the slim as possible approach. Plus the ability to drop in a VZW sim and it just works IS a MUST for me.

Only if you use TMO's downloaded app which is utter $4!+ IMHO.
I hate it so much I just dial in to listen the old fashioned way. I screen calls anyhow so the ONLY time it rings I know who is calling so not really a big deal. If callers don't have the secret PIN they get hung up on! F robos!

What about roaming on T Mobile partner network? Will I get a network on my UNLOCKED Galaxy Note 20 Ultra if I am roaming on US Cellular or any TMobile partner Network?
Will my Unlocked Galaxy Note 20 Ultra support all 5G bands from TMobile? (Low, Mid and High ) Layer Cake so to say.
What about SA 5G (Stand Alone 5G) that TMobile just launched. Will the Unlocked Galaxy Note 20 Ultra support it?

Sprint frequencies
I'm mostly concerned about the Sprint frequencies T-Mobile is picking up.

AT&T vs Unlocked US version

Are there any differences (Hardware like LTE, 5G Band differences or software differences) between AT&T and US Unlocked versions?

Hardware should be no difference. Radio bands should be the same. Software is different. The unlocked comes without carrier bloatware.

That is correct. The software is the only difference. I had the Samsung Note 10+ unlocked on AT&T. I couldn't get WiFi call or HD voice. This time I went the Note 20 Ultra AT&T version. Not a big deal. I just remove the bloatware from the phone using ADB. You can find articles on how to do it.

Weird that I was told by VZW that I couldn't wifi call on the unlocked version. But I can.

I had the U1 version on ATT. Worked great. Some menus missing, such as ability to choose VOLTE butncall quality was great. Has to call ATT to change to a 5g plan for 5g.

By the unlocked version, are you referring to the SM-N986B/DS? I am researching as well and I am on the AT&T network.
Edit: my bad misread title.

I had a U1 N10+ and as someone else mentioned, no wifi calling or HD Voice (VOLTE). Even flashing the U firmware. ATT typically has to Whitelist your phone to unlock those features. Running the U would unlock Video Calling (useless unless the other person is also on ATT) and Advanced Messaging (also an ATT only service). The day I got my N20Ultra, I popped my ATT activated sim, and no VOLTE / HD voice, and no wifi calling. Being on U1, the rest of the features weren't available (video calling, advanced messaging, vvm) which isn't surprising since it's debranded.
In another thread, it showed that Factory Unlocked N20Ultra will have HD Voice hut NOT wifi calling. That's fairly new, so YMMV. Saw the post earlier this week. Not sure it's it's live already or in the works. Some phones had support for WiFi calling and HD Voice, but the N20 series were showing only HD Voice at time of article.
I've since dumped att for Metro (Tmobile) for a few reasons, but primarily their reluctance for fully support a factory unlocked device. They are making a step in the right direction, but honestly, VOLTE and WiFi Calling should be standard features supported. Like why wouldn't you want me to call on wifi instead of clogging the wireless towers? Both work OOTB with Tmobile.
Edit: If you have no plans to switch carriers, I'd get it through att. Even if you run U1 for now, you can change your mind later and know all the features will work on U. If you buy factory unlocked, and need WiFi calling, there's no guarantee it'll work even if you load U firmware. In the past, the device has to have the IMEI specifically whitelisted on their end.

I spoke to AT&T for hours and they whitelisted my international Note20 Ultra IMEI. I still don't have Wi-Fi calling and they absolutely don't know why... I regret switching from T-Mobile to AT&T... but unfortunately have to stay with AT&T for 2 more years because of iPhone deals we got...

Guys, all you have to do is flash the U Home CSC for and you'll have all the features on ATT and still have U1 firmware on your U1 device. At least for me on this phone and two previous, the Samsung devices were already "whitelisted" with ATT

Can a US CSC be flashed to another snapdragon model, namely 9860?

No. If you're on the AT&T version, stay there.

I can't believe AT&T would whitelist all Samsung Unlocked devices, that would really surprise me. You can buy AT&T locked Galaxy phone and unlock it with AT&T since you bought it outright, and then of course it would be whitelisted.

Still Less Features for Factory Unlocked Models?
Read through this thread and tried digging around in all other logical forums and it seems that it's still the case that one cannot get WiFi calling on AT&T with a Factory Unlocked model?
Asking because Amazon is selling the Note 20 Ultra 512GB Factory Unlocked today for $1,200.
Found a Reddit thread that has people stating there will be a Samsung update that addresses this.
Have seen various posts in various places about flashing file(s)/ROM to enable this.
Any authoritative answer as to whether WiFi Calling (and Voice Over LTE) can be enabled on AT&T with a Factory Unlocked Note 20 Ultra? Or authoritative assurance it will, soon?

They cannot. Att and att based subsidized carriers. Do not allow byod on votle or wifi calling. I have a trick to make it work for a couple hours. So I know its possible. But after a few hours their systems reprovision your device and shut them back off.

Too bad. Thanks for the reply. Feel better about passing up the sale especially since it will probably be a common sale price during Xmas sales.
And WiFi Calling is too important a feature to trade for a discount of a hundred or even two.

Yea. If you provision volte and wifi on a actual att phone and sim swap they work for a while. Usually around 4 or 5 am. Then it shuts off and never works again. Till sim swap and reprovision

VoLTE on unlocked Samsung S20 and Note20 series phones is set to "on" by default, but unchangeable (greyed out). As of right now, there is no ability to select WiFi calling until Samsung decides to grace those of us with unlocked phones that ability.

Any authoritative answer as to whether WiFi Calling (and Voice Over LTE) can be enabled on AT&T with a Factory Unlocked Note 20 Ultra? Or authoritative assurance it will, soon?

There is a long term method but it involves calling att, and getting your IMEI registered so you can get VOLTE and wifi calling. Ask customer service. I can't remember the name of the department you need to request. It takes a couple of weeks and then you suddenly get a weird sms (something like IMEI provisioned) and then it works. Did it on note 9.

Question U1 VS Carrier Firmware

I have a TMO S22U and basically I immediately flashed to U1. I'm just curious are there any advantages I'm missing out on being on U1 opposed to T-Mobile U? I know there probably aren't many but I'm just curious.

Some say U1 us better. I'm At&t so probably someone on Tmo will chime in. But for me, U1 offered nothing over U. I mean yes no At&t bloat but I can disable what I don't want on U to get the desired affect.

My biggest thing was the T-Mobile splash screen, it sounds SO DUMB but flashing to U1 made it literally 100% Samsung for me I'm just wondering what could have been lol

The only thing I heard, but I am not certain about is that you lose the TMO visual email capability. Otherwise I have not heard anything else. I am on TMO and I kept mine on U. As butchieboy said, I just disable what I do not want. In all reality, there is not much from TMO that is loaded on the system side. More of the bloat is from Samsung and Google.

Thanks for the speedy replies guys much appreciated

One thing I noticed when I did the same thing, was I could not get 5G Ultra Capacity to work. Not certain I was doing anything wrong, just wouldn't work for me.

I think I read somewhere that you do get it, but there is no icon for it in the U1 image. It will show 4G LTE. Check your download speeds.

I did, 2 days apart in the same spot, the icon showed 5G as did the speed test connection type, but the speeds were much slower than 5G UC, almost 400 Mbps difference. Switched the firmware, back to the insane, almost WiFi type speeds.

Did you check the mobile networks setting to make sure 5G is available and selected?

Yes, that was my first thought. It never quite worked the way I should have.

preinstalled crap apps on tmo firmware

The main benefit for me on the unlocked firmware is the built in called id and spam blocking. For att you have to pay extra and tmobile has it on its best plan. But still think it works better than tmobiles implementation. And since i change carriers often i like to always have caller id and spam blocking no matter which one i use.

Can I ask what specific firmware you used to flash to unlocked?

I downloaded the S980U1UEU1 firmware which on the latest update ends with AVCK. Used Frija to download it

Carrier firmwares usually get updated a week before the u1 series does.

Would've just been a considence. U1 firmware does connect to 5G UC just look at the service menu and it'll confirm if your connected to N41 or not.
But I moved back from u1 to tmv U firmware due to having weird call /sms issues where it would just stop working and only fix was a reboot. Hasn't happened since switching back to U firmware.

Here's an interesting question..
I was on TMO and I bought a S22U from TMO (unlocked it with them afterwards) and of course it was on 5GUC and everything (I used ESIM). I got another sim (Mint Mobile) and when used as primary it would show 5G+
After a while, and just out of spite of the hideous 4G LTE TMO icon I Flashed the U1 firmware.. I'm no longer using TMO as I ported my number to Mint and it has been good.. Would it make sense to return to TMO U firmware or should I stay in U1 as Im no longer using the TMO sim?

Probably fine on U1. You're no longer connecting to anything advantageous besides updates being slightly faster with U.

I'm with T-Mobile, but purchased mine directly from Samsung.. I have the S22 Ultra U1. Since my last phone purchased from T-Mobile A52 5G. biggest change, No daily spam calls or text.. What a difference that makes.. With T-Mobile, their so called Spam blocker was notihng more than a spam attractor. Plus no more of the hidious bloat and splash screen..

I have the unlocked and I dirty flash switch between U and U1 depending on which newest ROM is out. There's absolutely no difference save for the annoying TMOB splash screen and that it says UC ... But from my extensive testing the speeds are the same whether it says 5G on the U1 or 5GUC on the U.
