I’m from the UK and want to buy a Samsung s7 edge from eBay to give as a gift to someone in Pakistan. How do I make sure the Phone I buy will also work there as I think these are European models? Is it just any S7 edge with a G935F model number?
Thanks in advance, really would appreciate some help as I don’t want to make a £400 mistake. Thanks
Pakistan will support the G935F. The person that you are gifting may need to change the CSC / firmware of the phone to have features such as Video over LTE, Voice over wifi or Voice over LTE working, depending on where the phone is from and therefore its firmware/csc. This can easily be changed through Odin and does not trip the knox e-fuse (what voids your warranty and stops Samsung pay from working).
What is CSC? it stands for "country specific code" and is responsible for the set of features a phone provides based on its country and sometimes carrier within country. Different carriers within a country may have different codes for different feature sets.
3G and lower calling will work fine. 4G for internet should work fine, they should be always enabled regardless of CSC.
Hope this helps. Any questions, let me know.

I have S3 from Rogers locked and was told even if I were to unlock it my model wouldn't work on WindMobile. As I haven't bought S6 Edge+ yet from Rogers, I can't tell you what model it'll be so lets say it is not compatible due to the bands. Would unlock code make the bands work on any provider? or would I need to mess with the firmware flashing or whatever the name is with a bootloop every time the phone restarts? I know close to nothing what I'm talking about firmware etc. so bare with me =)
Explain my options, and point me to the direction where I should research. I don't mean to spoon fed but one spoon full is enough to be taught.
Thanks in advance

You would need to check the supported bands for that specific model. Unlock codes are used so that the device isn't tied down to the carrier and you can activate it on any other supported carrier, but if the new carrier uses different frequencies then you are out of luck. And you cannot change your phone's supported bands.
Your can research the supported bands of the carriers that you might be planning to change to and purchase the phone that is compatible with them. Once you have the information verify it with the different models of the s6 edge+ to see compatibility.
You could also look for another phone that has most bands by default like the Moto X or the Nexus.
I use Cricket and would like to get an S7 edge and be able to use Samsung pay. But i'd like to still retain having the frequency bands to allow me to switch to another service if i end up disliking cricket later on.
But there's a few questions i cant seem to nail down answers for through searching...
It seems like the G935F is a great choice (exynos and no bloat) but Sammy pay is still somewhat questionable on working? It seems like people are getting it to work, but would i be able to purchase an EU model from amazon and it would just work?
Are the G935A and G935T models the same phone but locket to each carrier, or do they legitimately lack the bands the others support?

The AT&T G935A, T-Mobile G935T and Verizon phones can be unlocked to work with any sim card,
however they can never be rooted. The Samsung pay feature will work fine in any of these 3 phones.
The international S7 Edge G935F comes unlocked and is very easy to root but Samsung pay is not
compatible with it even if it's not rooted.
The only Samsung phones which are fully compatible with Samsung Pay are those which come with
the Samsung Pay app in the phone's app drawer and are not rooted.
Good luck,
Have a great day,
I've been combing the forums and I'm still unclear on a few things and looking for help. Current AT&T customer and I plan to switch to T-Mobile soon. Any confirmation or corrections/answers to the questions/statements below would be really appreciated.
1. The 935F variant is the international model that works with all GSM carriers (and I assume without any carrier bloatware) but VoLTE and wifi calling will not work on any GSM carrier here in the US. Theres a secondary 935F model (d?)- whats the advantage there? Shopping tools that let you compare the models show no difference but always priced differently. There is something I'm missing.
2. The 935U variant is official US unlocked model for use with any carrier. Only silver. I have not seen any posts confirming that VoLTE and wifi calling works- and will continue to work if you switch carriers.
3. Lots of listings for factory unlocked 935A variants. Official AT&T version. That just means a reseller has applied unlock codes to each and resells them? I'm very unclear here. Listings always say compatible with all GSM carriers. But will AT&T bloatware, logo continue to survive? And again, will VoLTE and wifi calling work and continue to work if I switch carriers. This is also the cheapest phone to buy virtually new. But if truly GSM compatible with features that are important to me are intact among carriers- what would I get for the significant premium to get the 935U? Besides, I wanted black.
4. Black Pearl- has this been released in the US and in any specific model? I have not seen one.
Thanks in advance. Really appreciate it.
FD is dual sim. You can put 2 GSM simcards there and both are active. Can send and receive sms or calls.

You can install 935U stock firmware on att/tmobile/verizon version. If used on tmobile network, you will get wifi call and volte. For att you have to install or have att stock.

1. 935F is the European / International model. 935FD, D stands for Dual-SIM, both slots will be able to accept a GSM SIM card and are usually used, as one for work, and one as a personal number. Dual-SIM however, is not a popular concept in the US.
2. Check the 935U threads, if a CSC flash is possible, it might work. Though, I'm not sure.
3. Yes, if you have an AT&T phone, it'll still have the AT&T ROM, which will always remain the same, regardless. It will work with other carriers, meaning SMS, Data and calls are compatible, but things like VoLTE and WiFi calling might not work on the carrier that the phone isn't intended for.
4. No it hasn't. It's been released in South Korea with 128GB of internal storage. Also available in the UAE, India and some other Middle Eastern countries. Only in a Dual SIM Configuration (SM-G935FD), and with 128GB of internal storage. It's a limited edition phone, and not sure if it'll be launched in the US.

A couple of followups if thats ok:
1. So if I purchase a "factory unlocked" 935A, before I insert any SIM, I can immediately flash the 935U firmware and it will remain unlocked? I couldn't find a single post that said VoLTE or Wifi calling worked with the 935U firmware on T-mobile (AT&T- what do you have to install?)
2. Flashing to firmware is not considered rooting the device? My work will not let my device connect to the network if it is rooted.
Seems like there is no reason to spend the extra money for the 935U variant. I can save hundreds and purchase an unlocked 935A and flash the firmware. I've rooted devices before and the process looks similar.
Thanks.

According to other people in verizon 935u thread and att 935u thread, volte and wifi call works on tmobile. For att wifi call and volte, it must be a ATT carrier firmware. ATT only let their branded phones have wifi call and volte while tmobile allows any phone to do this. That's why with 935U wifi call and volte will work fine on tmobile.
Every time you insert a new sim the phone will adjust settings, so there's no relation with what you can install.
Flashing is done through Odin while phone is in Download mode. There no root involved.
Hi all,
I lived in the US but recently came back to the UK. I got an unlocked S8 (SM-G950UZBAXAA) and I was wondering if I can change the CSC to BTU from XAA, since I haven´t got Spay to work
Cheers

oh, maybe I got the name wrong. I mean that since my phone is G950U I can only use CSCs that are available for that model. THE BTU or XEU is only available for model G950F, so I cannot get them on my phone. Is that right?

So that may be true (although I'm not completely positive you couldn't ) that they do not make CSCs for you device on those networks, but a CSC is not necessary to use an unlocked phone on a different network. I have been travelling overseas with tri and quad and phones for years and the phone works just fine with a local sim in it. The CSC just makes your phone have local BRANDING and some configurations that the carrier wants. The radios all work everywhere. This may mean that you will have to do extra work to get custom carrier specific apps and stuff (like Verizon in the us has a visual voicemail app that many people who rooted have worked hard to get back) but the phone will make and receive calls just fine.
Think of it this way, many people in the carrier switch thread have made their us snapdragon devices XAA CSC which is unbranded us generic, and they all can make and receive calls just fine. The point of sim unlocked phones is that they can be used anywhere the radios can pick up signal, and yours supports every uk 3g utms and lte signal your country uses.
Maybe someday I will prove this completely by flashing an exynos CSC on my g950u and show it doesn't brick or even fail. Might put this misinformation to bed.

Thanks for your post, quite informative. The reason why I want to change the CSC is mainly for samsung pay, which seems to be limited to us cards on this phone. Other than that, everything works great, and it is not a big concern, I think I will just forget about samsung pay and use android pay instead (althoug it would be good to be able to get some of the promotions available, so I may pop up to a samsung store and ask if it is possible to switch)

If you are staying not rooted and stock there may be a way to do that without CSC change I don't know I haven't looked into it
I'll stick to the "official" set up for now, but I'll keep an eye in case it can be done in the future. Too much information for me! Maybe when root is finally achieved it will be possible, who knows
First of all I want to clarify that I am new to this, so I would be very helpful to help me understand this world, I am from Mexico, let's begin.
Good companions I previously had a galaxy s7 model SM-G930T, the device was with the T-mobile company that is from the USA but it was unlocked so I could use it normally in my country, the device had its T-mobile bloatware so that everything normal, well I decided to use samsung pay on that mobile, practically everything worked perfectly, then I sold that phone and bought what I now have that is a galaxy s8 model SM-G950U1 out there I have informed that it is an unlocked mobile from United States with CSC XAA, I find that I can not use samsung pay, when wanting to make a temporary transaction of my card to activate it does not do it, the truth is confusing to me as if I could use sPay with the s7 and now with the s8 No, if both were from the USA, they could help me. :crying:
I am very new in this of Roms of other countries, csc, etc ...
Thanks for your attention.
