Hi all, purchased a Note 10+ for my wife to replace her Note 8. In short, Samsung pay used to work but when setting up everything for the Note 10+, its the only app i cant get working for her.
Says the phone doesnt support it. We are Aust based and i purchased from a Au seller. The website indicates its a AU/NZ model (SM-N975F).
I can get Google pay to work but not sure why i cant get Samsung pay to work.
Ive read about it begin region locked etc but as mentioned, the seller website indicated its a AU model. Also read that factory resetting may work but it was a new phone that i only just setup/restored data etc so dont really want to do all that again if theres no guarantee thats even a plausible answer.
I also read that when setting up the new phone, the simcard needed to be inserted from the very beginning which i did not do. I restored data via samsung switch first before transferring the sim/sd cards.
When i attempted to install an older Samsung pay apk, it goes 1 step further with the intro screens but then says connection issue, try again later.
I did search XDA but could not find any other threads that could help.
Anyone else in the same position with a simple fix that worked, thanks.

I have a similar issue I have a N975W (Canadian) in the UK & can't seem to get SPay for my region, I'm stuck with the Canadian APK/firmware, with yous being a N975F seems it's region locked to Europe but with a Austrian CSC maybe?
In a nutshell until Samsung remove the region restriction for SPay (which they probably will never do) you're out of luck, sorry.

Go to settings, about phone, software information.
Scroll down to where is says Service Provider.
What does it show?
Should be 1 of the following for an Australian model.

If it shows something else, that could be part of the issue.
The SM-N975F / DS are sold in a number of countries, with different csc codes.
The CSC I listed are for Australia, Samsung, Optus, Telstra & Voda.

VNZ is New Zealand
It's a New Zealand model, specifically it appears to be a Voda NZ model.
Either way, this is possibly why you can't use Samsung Pay.
Unfortunately, I'm not aware of a way around it.
Perhaps you can get it refunded since it doesn't fully work here?

Cheers, appreciate the info. Ill have to clarify with the seller then on how they can promote it as an AU/NZ model when it appears it has to be either one or the other. If i had an AU model the CSC as you guys have pointed out would be right and i would not have issues with region based apps like Samsung pay.

I followed all the directions I can find. Flash a different firmware. I tried New Zealand and still the CSC is MID (Iaq) which is what it was when i got it from Amazon. Its a 975f/ds which I bought specifically to be able to root it but this whole CSC thing is new to me since I haven't been in the rooting scene for 3 years which is when i gave up my beloved note 4 (best Samsung phone ever made by the way). Just trying to get samsung pay working so i can get it working on my samsung watch then i can flash all the awesome roms for my phone... any advice sure would be welcomed.

So I am going to try to flash stock firmware for XSA and see If I cannot get Samsung Pay to work. Not that I will need it really since I'm going to root anyway but its fun. If I get it working, I'll report back.
I flashed the AUS Firmware and Samsung pay seems to work BUT... Grrr. It asks me to sign into my Samsung account. Done. Then it asks how to verify authentication it has a grayed out button to use fingerprint and a button to use pin, and a little spinning blue circle in the center of the screen and that is where it stays. Like its loading something but never loads. The use fingerprint button never lights up, and the use pin button isn't clickable. So close... Any ideas?
I am looking to get this phone and needed some advice. I haven't bought a cellular branded phone for a long while. I usually go with the USA Factory unlocked version. On this phone is the cellular named stamped on the back of the phone? I know the model for the USA Unlocked version is G820QM (with a 7 at the end at times) but it is honestly harder to find. What does everyone recommend on this phone in regards to getting the cellular branded one or should I keep trying to find the USA Unlocked version? What about bloatware with the different cellular branded ones? How is that? Can you get rid of the bloatware? I also like what I call the LG Branded ones as they get the updates faster do they not? Please help me. I am looking for a phone and this one stuck out at me unless someone suggests a different phone with similar specs to this one? Thanks so much! :good:

Unsure where you're from, but stay away from the AT&T unlocked model (my model G820UM), I'm from the UK and ordered one, big mistake, AT&T does not send any update to their phones if they are not using an AT&T SIM card in the US, some users have been successful in updating they're OS, by just using a AT&T SIM card outside of the US, some haven't and I haven't tried it, because I don't want to waste more money on a SIM card when the results are not 100% guaranteed.
There is no way of cross flashing a different ROM, so you will be stuck without updates, until someone finds a way of cross flashing a ROM from an unlocked model. I'm checking this forum regularly hoping some has found a solution, but nothing so far
If you are in the US and on AT&T then it will fine, bloatware (which is a lot) can be removed/disabled easily
Honestly, for the price I paid (£280), I think the Xiaomi Mi9 would have been a better option, similar specs, updates every 2 months and you're able to unlock bootloader, not the best process to unlock the bootloader, but still possible (just need to wait for permission from Xiaomi which could take a few weeks), you'll be missing out on the best headphone jack, better cameras (not by much) and better battery life, for a similar price I think this is the best deal for snapdragon 855 phone.
If you don't mind paying a bit more and want the same features as the G8, go for the Samsung S10.

Yep no luck, I've sold the phone, I was wasting too much time trying to find a solution, so just sold it and claimed my sanity back xD
Going back to the trusty Xperia 5, timely updates and great software and they are going for around £260 so easily recommended.
That's too bad, AT&T must be interfering, because I just purchased an unlocked G8 in Canada, and it updated to 10 over WiFi, before I inserted a SIM from my carrier (Bell Mobility). Phone was not on Bell originally.

Yep, this a AT&T "feature", want updates? Buy at AT&T SIM card and use it in the US, guess they don't want anyone outside the US to use their products, unsure why, but it is what it is...

Is 10 really that big a deal from 9? I have 9 on my phone i could care less if it gets 10 and I am pretty sure it wont , lol
I feel like if we have temp root then it's only a matter of time before we get TWRP and roms. I just picked up an AT&T model for $178. Not sure if it's unlocked, but fairly easy through AT&T. Just worried if we have an exploit, updating to 10 might invalidate it.
I come from PS3/xbox 360 hacking, haha.
I have a Note 10 Plus N975U1 that was sold as a Consumer Cellular device through Target. The phone came with the N975U1 unlocked ROM installed on the phone and there is no carrier apps or Consumer Cellular identification anywhere. The only reason I know it's Consumer Cellular is because of a message that popped up for something, can't recall what now.
Anyway, the phone acts just like an unlocked model. Put in various sim cards and the phone reboots through the blue recovery screen to update carrier software for the sim you are using. APN settings are available and can be edited. Everything is just like an unlocked model.
Except, it connects to the network for a couple minutes or so and then stops working. It acts like the Verizon versions do before they are unlocked by Verizon. Except the Verizon versions give you a little pop up stating the phone can't be used on another network. This model has no message.
I am guessing that they are locked using the same mechanism that Verizon uses for locking their devices now except they just are not showing anything to let you know.
Is anybody aware of exactly how this is done and any third party who can unlock it? I have tried a couple different unlocked ROM s as well as an AT&T and Verizon just to see what happens. Same problem.
Thanks
Have a link from the target site to the phone you bought?
I have a feeling that the phone is not actually unlocked or it may not be as what it appears exactly. You can run the IMEI number using swappa and see if the phone is indeed an U1 variant or just the normal carrier N975U.
It maybe possible (not sure how exactly) that your using an international variant that was flashed and configured to look like a N975U1. For example the phone listed here is an international variant that is compatible with US LTE, but I have some serious doubts with how compatible it really is. From past experiences with a local store that sells unlocked Note 10+ units for Net10, I discovered they are not actually US models and are really international models. They were flashed and configured in a weird way (best I can describe it) that it would work for the most part, work with Net10, but it would not work with the other providers here locally. It would at first appear to work but then fail all together.. It wasn't until I started digging into the IMEI number and what it belonged too that I discovered the truth of what the model actually is, and I then promptly returned the phone to the store I bought it from.
If the phone is just network locked and a genuine N975U1 model it would just seem that you only have to use the phone with the service for a certain period of time before they will unlock it. Consumer Cellular would be the best place to go to get (and ask about getting) the phone unlocked.

I resell used phones and specifically phones from Consumer Cellular. All the previous Samsung models used to come unlocked, but about the time the S10 was released, all their Samsung phones came with this unusual lock. I've tried working with countless unlockers and no one has been able to remove it. Once it connects to the internet, it downloads some google update and the phone loses voice/data service. I've wondered how they do this too. A few other models I have that have the same lock are the A10e A20 J7 S10/+ S20/+ Note 10/+. Really really frustrating as I've been searching for a long time now. If anyone knows anything, please let me know. I have hundreds of these that need to be unlocked. Also to clarify, yes they are all the U1 factory unlocked models.
Edit: Apparently when a carrier locked device is flashed to U1 firmware BEFORE unlocking, there is no software prompt to unlock the device. It probably was a carrier locked N975U originally. Maybe on Consumer Cellular firmware, there would be a prompt to unlock it?
These are the guys but they only do commercial work. I am pretty sure they never fail unlock.

These are not the U versions. I've sold CC phones for years and they are and have always been U1 models. Not only does it say it in the software, but even on the back glass. They are locking these things with an update somehow.
I'll reach out to swiftunlocks, but I would put a big bet up that they can't unlock it either. I'm connected with some of the top unlockers in the world as this is my business and no one has any idea. If anyone is reading this and wants a phone to test, I'll even send you one if you think you can unlock it. It's worth a lot of money to me to find a solution. The worst part is that these phones are all paid off and eligible to unlock through the carrier, but since "I'm not the original owner" they won't help me.

I personally use samkey.org
Hello.
Here's the back story. Bought my phone from Egypt unlocked s20 plus. Recently moved to canada and trying to get samsung pay to work. Downloaded the app from google play canada but it says that device is not supported. Downloaded it from APK mirror but it just says it needs to update, even though this is the last version.
I was told that getting the BTU or DBT CSC might fix this, since they come preinstalled with samsung pay.
First of all, can I do this by just flashing the firmware (not changing CSC)? Or do I need to change the CSC using samkey? I don't mind flashing first, if that didn't work then using samkey. But would rather go with the route that people think will work straight away.
I'll write all my device's info that I think might be needed to make this as complete as possible. Then I'll put some questions that are confusing me.
So to start this, I bought my phone from Egypt and I'm currently in Canada. Since it's a dual sim model, I have a Canadian SIM as my primary and Egyptian as my secondary. Currently, I'm getting wifi calling but not VoLTE. Reading a bit on this, some people are saying that my network intentionally locked people out of this option if they didn't buy the phone from them. My network is Fido btw.
Model: SM-G985F/DS (4G)
Product Code: SM-G985FZADEGY
PDA: G985FXXU4BTIB
CSC: G985FOXM4BTID
Basebad: G985FXXU4BTI6
Bootloader: G985FXXU4BTIB
September Security Patch.
One thing I'd like to point out is typing "*#243203855#" in the dialer does nothing. Maybe it's because it's not supported? Or the fact that I have dual IMEI?
Questions:
1. Is there benefit of using DBT over BTU?
2. With my bootloader being BIT 4 (I think?), can I use samkey? When I checked it, it said that they only support BIT 1 and 2 on their website. I could be wrong.
3. Is it safe to purchase samkey credits off ebay?
4. Is samkey itself safe? It showed up as a trojen when I installed it. Could be a false positive? Downloaded from the official site btw.
5. Is flashing BTU enough for this to work or do I need to change the CSC?
6. Can I revert any changes that I've done to restore the device in its original state? If I change the CSC, can I revert it back to EGY?
7. Will I get normal OTA updates while I'm here in canada? This applies to both flashing and/or changing my CSC?
8. I would love to keep wifi calling, call HD, and hopefully get VoLTE (but I understand that this might work). And obviously the main reason for this whole thing is getting Samsung Pay to work.
Sorry if these questions might be obvious, I'm really trying to understand this so I don't ruin anything and don't regret anything.
If someone is willing to help me further, I would greatly appreciate it.
I am unsure about majority of the things you have question about, but one thing i know for sure - samsung pay on my s20+ was rarely working making me look stupid at the shops - since i switched to google pay all issues are gone and payment is going through everywhere

The one thing that I care about with samsung pay is the magnetic card replication. I forgot what it was called MTP, or something? This is something that doesn't work with google pay.

The MST function was disabled in 2019 for all the smartphones sold within the EU (at least) due to a new regulation regarding MST technology.
I don't know if it's working elsewhere.
Still, for me SPAY has been working flawlessly for over an year or two, never had any problem, with or without MST

Oh? This might actually be useless than. So this is a hardware change or a software one? Since mine was bought from Egypt. I plan to flash the UK software on there. I'm not sure if it'll have it or not in this case. I guess without MST, what's the point of using samsung pay over google pay?
Hi guys! I hope this thread has not been answered already but I've looked on this forum and on the web and couldn't find anything.
Basically I bought this S20+ 5G online and when trying to use samsung pay I discovered it comes from the UAE. It didn't bother me too much, I had some compatibility issues with my cards but I didn't plan to use the samsung pay in any case.
However, when I came back to Italy (as I was in France when I bought the phone) I was excited to try vodafone's 5G network in Rome (already checked with them and I'm abilitated to 5G) but my phone never connected to 5G network. I even tried with a friend's 5G iphone (always with vodafone) and while his phone connected mine didn't.
So, I've looked around for some possible reasons and my conclusion was that the issue came from having the wrong CSC codes, which are XSG/ITV,XEF/XSG. ITV and XEF make sense, as I have an italian and a french sim card, but I can't manage to remove the XSG; I tried to flash the italian ITV firmware (from sammobile) through Odin but nothing changed (I must say I did it using the Home_CSC, so that may be the issue).
So, long-story short my doubts are the following:
- Do you guys agree that the issue wuth the 5G connectivity may come from the XSG part of the country codes? Or should I look elswhere?
- If I flash the italian firmware cleaning also the data on the phone, do you think it will work? Will it invalidate the warranty and knox (as I read that the knox services are somewhat delicate if the phone is modified). I mean the samsung services are useful and I wouldn't want to screw too much with them.
- Should I just surrender to having a 5G phone without being able to connect to 5G?
Thank you so much for the help! I'm really losing my mind on this ahahah

"I bought this S20+ 5G online and when trying to use samsung pay I discovered it comes from the UAE"
So you failed to research Samsung models and attributes, that's on you. Samsung is also responsible or should I say irresponsible? They produce way too many models in addition to multiple firmwares from all the various service providers. Not only that Samsung has made it much more challenging in resolving compatibility issues with proprietary firmware and multiple SoC's. It's actually quite simple, if you want full functionality and avoid alot of headaches buy your service provider's device. You may sacrifice in some aspects but you'll have a smartphone which functions the manner it was designed to operate.
