Unlocked on T-Mobile Require Flashing? - Samsung Galaxy Note 20 Ultra Questions & Answers

I have the unlocked phone on T-Mobile... Haven't done anything but insert the SIM. Is there anything I have to do for this phone to be fully effective on T-Mobile?

I took the SIM from Note 10+ put it in the Note 20 Ultra, it prompted for a network update and was good to go. Picked up 5G immediately.

Yeah same here... Hopefully that's enough! I saw people talking about flashing a csc file but I don't remember what the point is or if it's necessary.

I believe some were talking about flashing the (U) CSC on unlocked to get wifi calling.

Only put my sim in and I have wifi calling. Won't flash unless i encounter any problems.

I have Note 20 Ultra Unlocked on Tmobile, Wifi Calling and 5G is working. Video Calling uses Google Duo and i am not getting read receipt of messages(text or MMS) in Samsung Messages App. these are the only things i have noticed so far.

I'm still a sprint customer coming from the note 10 plus. When I insert the sim card into my unlocked note 20 ultra from my sprint note 10 plus,will I be able to access 5G and have everything work properly ?

LTE not functioning on AT&T

I've changed access point to the right settings and I still only get HSPA connection. I've searched other things online but nothing. Spoke to 3 reps. It says that LTE bands are supported so how do I get the best settings to get things running right? I've conveyed to international and the phone is totally unlocked. Sim and bootloader both. Am I missing something?
Thanks.
I'm currently visiting my wife in the USA and LTE is working fine for me on my 7 Pro 5G. Google the APN settings.

I did. I think maybe since it's not 5G version perhaps. At any rate I've gotten a fix the rep did.... Activated on another device like galaxy s10 then put back into my phone. I have LTE now since we've tricked the system
Also They are telling me they need to enter the imei range for all oneplus 7 pro phones which takes about 2 weeks. So hopefully the system won't figure out I'm using something other then S10 ?

That's rubbish....I'm on Vodafone in the UK and as mentioned, I'm currently visiting my wife in Illinois and I have full LTE service on AT&T.

Rubbish perhaps but that's what they've told me and until the rep did the trick to my sim, only got 3G. Maybe this temporary thing will be perm since he said for his Android the system thinks it's iPhone 7
I'm on AT&T with my OnePlus 7 pro and out of the box with my sim it works like a charm.
Currently "VOLTE" is displayed on top of the phone and I'm getting good data speeds (will post shortly)
I'd say something wrong on your sim or account end.

Same here. I got my 7 Pro (US unlocked version - not 5G) on June 10. Simply put my AT&T SIM in, and it works perfectly on LTE. Did not need to enter APN info, or anything.

That is pretty good of the rep to work out some solution. They could have just said "We don't support your device."
Over the years, I have used several international phones on AT&T. The issue is if you establish a new line on a new sim card, lte must be "provisioned" (their term not mine).
To provision the new sim card for lte, we need to put it into an AT&T branded phone first to activate the lte, or call customer service and give them an imei from an AT&T branded phone. Once the sim card is provisioned for lte it can be moved from phone to phone no problem.
For that reason, I still keep my AT&T Galaxy Note 2 around. Anytime I get a new AT&T sim card, I put it into the Note 2, wait until I see it has lte service then it's good to use in any international phone.

Unlocked Version on Sprint

I cant seem to find out. Will the unlocked version work on Sprint. I get a much better deal if I preorder the unlocked version, but I'm on Sprint
The previous ones did, so I don't see why not. It supports Sprint's CDMA bands. That's the one I ordered. Pretty confident that it'll work.

Thanks. I know the OTA updates take longer, but I get more off if I order that one and trade my Note 8. Im only getting the regular Note 10. I feels more like my beloved Note 7's size.
I have an unlocked Note 8 that I use on Sprint. I actually loaded the Sprint firmware to get VoLTE as well. I plan to do the same with the Note 10+.

Sprint firmware? I ordered the base Note 10 unlocked and got a Sprint sim card for it directly from Samsung using their Galaxy forever program. I can trade it every year and basically be paying 1/2 the cost of a new one. It will ship on 9/4. The Note 10+ is just way to big for my small hands. I'll keep my Note 9 as a backup, traded the Note 8, and the Note 9 will be used when I need higher specs. I do like the thinness of the base Note 10 as well. Looking forward to it.

I too ordered the Note 10 as + would be too big When you get your new phone and put in Sprint sim, check to see if you have anything missing, feature wise(WiFi calling, VoLTE). If you don't then you are fine, if you do, then flashing Sprint firmware is an alternative.

Wifi calling and VoLTE seem to be intact. But keeps saying WiFi calling app missing. Radio signal can be weak at times.

Hmm, WiFi calling is built into the system, so there should not be an app needed here. Did you transfer your data, settings from your previous phone? Maybe that device had wifi calling app which got onto your new device and somehow conflicts with the current settings

Yes, initially restored from Samsung backup, then from smart switch. I just wanna make sure I have the best modem firmware. This is the first time in a long time I'm getting 1x or 3G signal where I always got 4G/LTE.

If you flash it to SPR, you would get OTA updates when Sprint pushes it and you will be able to re-flash it to original unlocked firmware or to another carrier. I have T-Mobile firmware on my Note10

U1 is what you have. You need U, if you want SPR firmware. Run SamFirm app on your PC and type in your model as: SM-N970U and for region put: SPR. See if Auto is selected and and on the right side see if Check crs32 and decrypt auto is selected hit check update

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 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.

Unlocked Pre-Order from Samsung w ATT SIM - will I be able to use WiFi calling /VoLTE

Current Note8 user on ATT (phone locked to carrier). I pre-ordered a Note20 Ultra from Samsung direct, unlocked version. Have been off XDA really for a couple years and not rooting/modding much lately but have read that ATT will not allow unlocked phones on their network to use WiFi Calling and/or VoLTE. If true, are there workaround options for me (assuming I stick w ATT as the carrier I mean) to get these to work, or should I cancel the unlocked model and order the ATT version? Was hoping to root eventually and remove bloatware / play w custom ROMs again on the Ultra etc etc. - that is why I ordered an unlocked version.
Thanks gents for the guidance here! Best forum around for us phone geeks
If it will be like Note 9 or 10 plus just have to flash the U version csc with odin and it will give you wifi calling advanced..messaging..volte

Did not work for me on the unlocked note 10+. Worked right away on the tmobile.
Att was actually fun to have. Nothing that att expected worked on the unlocked device. For example I had unlimited hotspot, despite it was not included in my att plan.

That's bizarre. I am rethinking this unlocked route. I must have wifi calling since signal at the house is terrible in my area. I don't need the drama of uncertainty if this will work or not. Might as well cancel the unlocked one and just upgrade via att. Oy. Wtf is with att these days? They lost my directv account last year and now their wireless policies are looking like a royal pita.
I don't think you have to worry .... ATT seems to consistently allow Samsung unlocked devices to have carrier functions
You just have to flash the U CSC as mentioned above. Worked for me on Note 10 and is currently working on a s20 ultra device

I strongly recommend switching your order to the ATT model. I got my note 10+ unlocked based off the suggestions found here saying that flashing the att firmware would give me all the features, and I've been through a year of headaches.
For a little wile i was able to enjoy wifi calling, voicemail and VOLTE, but after my first software update the features were lost. i was able to get them back briefly by putting my sim back in an old Att phone and keeping it for a day or two, but that trick never lasted past a week. I've tried re-flashing the software, switching back to unlocked and then back to ATT, basically anything i could think of and it never worked.
calling ATT didn't help either, as the reps gave me a canned line about not supporting outside phones. the whole reason I'm updating to the 20 ultra is to just get my phone fully functional with an ATT model

Thanks darth. Yeah, I switched to the att version. Hate the hidden tracking bloatware etc that comes with it but must have a very workable phone for daily work calls and wifi calling is a must. No drama is my motto these days. Thank you for reporting your experience.
I had the same situation with my unlocked Pixel 4 XL, keep calling ATT until I got the right person to modify my sim to allow WiFi Calling to work, that's my plan when I get my unlocked 20 Ultra.
I'm not a gent, but I doI have the Note 20 Ultra in for review and am using it with an AT&T SIM. VoLTE works, no option for WiFi calling.

What worries me is the 5G. Will unlocked work for ATT 5G?
It does on my unlocked Galaxy S20+ 5G. The Note 20 Ultra is a ways to release and their system doesn't yet correctly identify the IMEI, so I can't say for sure what will happen after release day.

Hi Lisa,
Your reviews are the best, so thank you first of all. Can you check if it has any eSIM capabilities? Supposedly S20 was going to get an update to allow eSIM use in US but that never happened...
Thanks . I'm not seeing anything under connection settings on our US unlocked Note 20 Ultra (there's no IMEI listed or cellular network option listed under connection settings when no nano SIM is installed. EsimClient is running on the phone, which makes me think the hardware must be there. EsimClient is not running on my GS 20+ unlocked.

Great, thank you for checking and comparing with S20+ !
eSIMClient running gives me hope that we will get eSIM support in an update...Still perplexed how or why Samsung has gone out of the way to disable eSIM on US variants when Apple, Google support it.

Ha! Thanks Lisa (love your tech vids!!) - I switched to the ATT version. Supposed to be here 8/21. I can't take a chance with wifi calling being borked, or that just that I may need to Odin-flash updates or CSC packs periodically to keep up with the monthly patches (ie force an unlocked unit to keep working on ATT's network if my previous firmware gets overwritten etc. I mean). I guess as I got older I went from a tech pioneer and adopter to just an end user LOL.... I just need it to work. Maybe I can do that package remove thingy and chop the bloatware periodically... we shall see once the community gets these units and starts their dev magic for us.
I guess I will need to make an appt at the local ATT store in a week to get on a new 5G plan from my current 4G one to take advantage of the coming speeds.
You're welcome- glad you enjoy our vids! With AT&T, you can simply change your plan online, no need to visit a store. The mid and high tier unlimited plans include 5G.

Could you tell me more. I have the US unlocked note 20 ultra, I put an AT&T sim in (from my note 9 unlocked) and I can't find an option to turn on wifi calling. I pretty much gave up on feature like this, because I would rather have the unlocked phone, but if it works now maybe I am missing something.

Reach out to US Mobile, Could be an issue on their end. Not long ago they had an issue with the S22 series with no 5G until an update that came out this month or last month that fixed it.

If it is this case, not US Mobile can fix, right? I still need to wait update from Sansung. Exact same SIM with Flip 3 do have 5G. It is more likely phone radio issue rather then US Mobile.

I have this issue on Verizon. Very annoying
Cross fingers and waiting for next update.
Not sure if this is relevant but I have a Flip 4 here in India and the network reception is way poor than it was on my previous handset OnePlus 6T. I think the reception is very bad with Flip 4. Flip often black out on network.
Update: Finally I got 5G. Happy. I am using US Mobile service which is Verizon MVNO. I had only LTE+ since I start with this newly Flip 4 ( unlocked version direct from Samsung )
I use ODIN and flash VZW-F721U1UEU1AVIA. Little bit scared while doing the flash. Got 5G right after and speed test indeed much better then LTE+. I use HOME_CSC which keep my user-data intact, everything still there after reboot.
