Samsung Galaxy S 5 unlocked but region locked and triple sim adapter is blocked

Just a word of warning for potential buyers that the region locking on the Samsung galaxy S5 is different to that on my Note 3. My note 3 is unlocked and can use different sims and software update without issues.
But had a Samsung Galaxy S5 for more than a week, got it before UK official launch as it was a Korean model 32GB LTE snapdragon version, it was unlocked and was able to use several different sims from various UK networks but couldnt software update as phone would keep asking for SKT (south korea telecom) sim for software update even though would work with other UK sims for calls data and text for more than a week of me using phone. worked fine for streaming thousands of songs via google music and deezer and calls and texts but no luck with software update. see alert shown by phone on attempting to do software update https://plus.google.com/108877366358490804054/posts/X38mPrxYHmf
wireless charging worked fine though with Qi insert as shown on my youtueb uploads for the S5 which can be seen from my tagline below
Just a heads up to people wanting to import a Samsung galaxy S5 from abroad that their region locking is getting worse with every new phone.
Dont have the S5 anymore and wont be buying a samsung phone again..... due to region locking blocking features... like fingerprint scanner use in ebay app in the UK even though unlocked phone and also samsung has blocked use of triple sim adapters as it has blocked the loading of sim app need for triple sim adapters to work. The same adapters work fine on my s4 and note 3. The adapter was inserted correctly as my main sim works through the adapter but cant access the extra sims as samsung has blocked the sim app from launching on the S5 but works fine on S4 and note 3 and other phones.

Not sure about internationally, however North America region lock seems to be disabled if you first activate with the carrier that the phone was built for and then unlock. If you just buy a phone from a carrier that has it region locked and you never activate it with them, you will have issues.

The phone is already unlocked as I used different UK sims For more than a week. The region locking only becomes apparent when trying to software update the phone. The phone was on Kitkat but there was an update available but couldn't update due to the issue mentioned.

If it is the international model (G900F) just flash it with the stock UK S5 rom.

Do you know if it's possible to root and flash something else without having removed the region lock?

Dont have the phone anymore with me and think the person having it now is flashing cyanogen mod rom for this phone.
Dont think will be getting a samsung phone again as tired of the pr1ck5 at samsung p1ssing off paying customers with some locking cr4p or the other. Presently still have 3 other samsung phones (S4 note 3 and note 1) and many of my playlists on youtube have loads of samsung phone related. But really fed up with samsungs locking idiocy and will look to sony or LG from now on.

I don't think the SK Telecom model is the same as the G900F.
I think Korea uses some different network brands.

Don't look at Sony.
You will receive software updates like 7 months after the release of that android version.
My Xperia Z still doesn't have kitkat.

Region lock on the 900A
I am looking to buy the galaxy s5 for use in several Sub-saharan African countries. I already have an old ATT sim with me and I will probably be ordering the 900A in/from the US and i want to make sure that the region-lock is not an issue. Will i be able to region unlock with an ATT sim card while in Africa or do i need to have someone make the 5min call for me while the phone is in the US? and is this call meant to be to or from the s5?
Thanks!

No one likes self serving restrictions by manufacturers or carriers. But Samsung is far from the only manufacturer doing things like this. And region locking is one of the easiest obstacles to overcome.
On single SIM phones at least removing the subsidy lock nullifies the region lock as well. In any event if you couldn't make a few calls in the area that the phone originated, you could simply have edited the region lock blacklist to circumvent the region lock.

I had the S5 but no longer have it. Bought the one plus one which is half the price but 64gb and miles better with no region locking crap and call recording apps work on it unlike on my several samsung phones. Call recording apps did work earlier on samsung phones and after software upgrades by samsung they no longer work on them. But they work on other android phones. So samsung is deliberately gimping android with their "updates". Sane way triple sim adapters don't work on the S5 but they do on my s4 and note 3 and other phones.
Coming to your reference to dvd and bluray. .. i don't but them anymore as have several paid digital subscription packages and don't buy dvd and bluray anymore as realised i haven't bothered to open the packs of several of my earlier purchases.
Several other android manufacturers don't region lock or block call recording apps or triple sim adapters so there are better and cheaper options.

did you research if the s5 was region locked, or had issues with call recording apps or sim adapater issues before you bought it. or did you buy it assuming they would work?

Are you a Samsung employee or funded by samsung in any manner!
edit: If you see my youtube videos for the S5 you might notice that i had uploaded my video BEFORE the UK release date as it was imported from korea.

region locking isnt an opinion. its an actual thing
heres my point
you want to buy a phone, you want it to have multi sim adapters support, no region locking and ability to record in calls.
you do your research like you do "all your purchases"
then you buy a device knowing these things wont work. then you ***** about samsung doing it anyway?

Dude pull that bee out of your bonnet. Dint you have anything better to do than dig up a few months old thread of mine!
Triple sim adapters work on the S4 and note 3.
Call recording apps do work on android phones and even older samsung phones and other new android phones and don't work on new or software updated older samsung phones.
Yes i know what region locking is.
I now choose to spend my money on other companies android products which i think are better. If that bothers you then that is not my problem. I have better things to do today than argue on the Internet with someone i don't know.
Good night.

My issue isnt with you buying anything. my issue is with you being such a vocal detester of certain features or lack thereof, when you bought them knowing full well they had these things wrong with them because you did the proper research.
why would you even buy a phone that you know wont work the way you want, better yet why moan about samsung doing this. even though you knew they did it before you bought it

One last time. .. my trile sim adapters did work then on my note 3 and S4 but they didn't on the s5. That was my experience as I hadn't come across posts regarding that it didn't work on the S5. The adapter actually 'works' on the s5 too in the sense that the sim number 1 works via the connector but the other sims can't be used as samsung blocks the launch of the sim app but it doesn't get blocked on older samsung phones. Ps. they work on iPhones and other android phones.
Getting to call recording apps. . They did work on s4 and note 3 and stopped working on note 3 after software updates. Sometimes software have glitches so I gave them the benefit of the doubt but since on the newer s5 it didn't work either and works on other new android phones like my one plus one it is my understanding that samsung is blocking some features which you can gather if you read up more on the topic.
As explained AGAIN above and
in my personal experience the triple sim adapters worked in s4 and note 3 (but not after software update indicating it is samsung doing the blocking) and didn't work on the s5.
Call recording still works on loads of android phones including my one plus one. It used to work on my older samsung phones till later software updates and didn't Work on the S5.
If you need more of my reasons why I think the are better ones out there than the S5....
water proofing is **** as shown in my videos. Sony is better.
Internal memory is loads better on cheaper phones like the one plus one.
Camera is worse than much cheaper one plus one.
Speaker is much louder on the one plus one.
Battery life "without cutting back any features" is better on the one plus one. But would be better on s5 using that black and white ultra power saving mode which stops many features working.
Edit. I still have my note 3 and note 1 and s4 but I do like my gadgets and have other 6 android phones, 5 android tablets and 2 android mini pc's and ipad air. So after owning the and using many other android devices which I no longer have my personal impression of the S5 is that there are better ones out there.
If the above bothers you then not much I can do but say agree to disagree. Cheers.

Ignore some of the apologists for Samsung on this thread trying to pester people who purchase their own android devices unlike the usual reviewers on many websites who get their free review phones and do your own research before spending your money.
Word of warning even when buying an unlocked or no region lock samsung phone in a country with no region lock, it can subsequently get region lock if you do any software updates while traveling or moving to another country with region lock as shown long time ago in the Note 3 thread (thread with hundreds of posts) http://forum.xda-developers.com/showpost.php?p=47664261&postcount=1380 As you can see paying customers who bought unlocked (no region lock phones) samsung phone later got region lock with software update while travelling and working in the Eu and their phone would no longer work with their home country sim. Please note phone was bought from official samsung store and not so called grey market what ever that term grey market may mean! So any person who travels and works across countries or even travelling abroad and wants to use roaming or local sims would be at risk of region lock unless they never want to update their phone or need to resort to hacking the software which most wont be able to do.

Importing a Snapdragon Model from U.S.

After comprehending the HUGE differences between the performance of the Exynos and Snapdragon model (thanks to Anandtech and Gary Explains YouTube), I am thinking of buying the Snapdragon model from U.S. and importing it to India. Wanted to know wether or not is it worth it, the hassles of doing so, and is there a better option than Amazon for it ?

I would strongly advise not going down this route. I did the exact same thing with my previous S8. What Samsung don't tell you is that they include a region lock on their devices. In order to remove the lock, you need to use 5 minutes of call time in that particular country to unlock it. I purchased my phone in the US and initially and used the phone to get the unlock, without any knowledge. The issues arose when I brought it back to the UK and flashed my own firmware. In this case, a beta firmware update. By doing my own flash, it then reset the lock removing access to the galaxy app store, samsung pay and a number of other apps.
You can find an example of this by simply googling samsung region lock.
If it's simply a performance issue, I would stick with the Exynos processor. My note 9 has had no issues in performance whatsoever and would strongly recommend the phone.

Using USA Note 9 in Europe (to be specific in Romania)

Hello!
I've been interested in buying a Galaxy Note 9 for some time, but I'd like a Snapdragon version (from what I can tell by reviews and tests it's better than the Exynos in performance, heat and battery and I don't really want to install custom ROMs, so no problem about the locked bootloader). Today I happened to stumble across an offer on a retail website where a seller just 20 km away from me is offering a Galaxy Note 9 which he says is new and bought from Samsung store in the USA (so I'm assuming it's the N960U carrier unlocked USA version), but he's also stating that it needs to be region unlocked. I've been searching online and I don't really understand what that's all about. I know the first step in purchasing a phone from retail is asking for the IMEI, but what can I exactly do with it? Does it provide the phone's exact model? And what does region unlocking imply?
I'd be glad if anyone could help me with this situation, as it's quite a rare chance and I'd be extremely happy to buy it, but I firstly want to be sure I can use it.
Provided it's not CDMA, the GSM bands should be comaptible with my carrier (Orange), or so I think. Any information is much appreciated.
Thanks and have a great day!

Is All Hope Lost for G973U US Snapdragon?

I consider myself an optimist and I want to stay positive. Honestly the main reason I opted for the Galaxy S10 was due to root support and phone development vs LG G series. I really am loving the performance of my phone. I've been rooting since the 1st Galaxy came out with help from this forum. I just hate to give up hope because there had always been some brilliant mind or mind(s) to crack through the barriers.
Just sucks all the other versions get to enjoy making their phone a little more fabulous than my US Sprint version ?
Thanks!

It's been a given fact that the US Snapdragon wont get root and it's been a well known fact for quite a while now. You should have opted for another model if you wanted root.

Well some of that was also dependent on those engineering kernels that got leaked on the last two models the Galaxy 8 & 9. Some devs were able to build off of that.

True. I will say I haven't had a Galaxy since S6 but I would always see support for Galaxy. I wasn't interested in the S9 as much so I wasn't aware of how restricted it had become. Over the years I've had Motorola X play, LG series and Axon. As I said I assumed someone would break they the barrier. I remember the 1st root breaking through Knox or finding a work around. Then the bounty collected to root other versions as they became more difficult. It's just weird how US would be so dogmatically restrictive. But it's not an end all for me. I love my phone and how it doesn't lag even with 20 apps open.

P personally don't think root is needed too much on the S10

Was there any hope in the first place?
North American Samsung are known to be locked, only a fool would waste time finding way to root it when 99% of the world use a different version that is already possible to root.

I came from S7 exynos rooted with Magisk, and was very reluctant to swtich out, but I needed modern radio so I took the leap with the S10e. Got the 256GB U1 version, flashed with Tmo U firmware, and I'm 99% set. Giving certain permissions via ADB to MacroDroid and other apps is so far enough (e. g. set lock timeout to forever when on home WiFi, effectively doing the same as some rooted solution, etc.)
The 1% that I still really wish I could have? Titanium Backup. Migrating phone with TiBu is so much easier, and it's more reliable too. I wish Android allows more flexibility to power users on this (Google or Samsung backup is still not good enough).

It's not, but some people think they have to have it.

Just in case, what's people suggestion?
In case we still able to return the phone, should we do it?
Does it seems some option for Snapdragon version in future, or better to give up and stockpile a return to the company?
For me, unlocked bootloader is a must, in order to remove crapware (like Bixby), remove Google, or just to get future support after Samsung declares it an "outdated device"
Suggestions?

Swift support and REAL call recording is still needed by many users, including me. Sucks that they both now need root. I wish I could use Oreo on this S10, lol!

I feel you dude, sucks that North Americans can't enjoy the same freedoms on the S10 compared to literally anywhere else. Doesn't make sense. I've always assumed that it was the US variants that can be easily unlocked? Perhaps because it uses the snapdragon chip, which I assumed was more easy to 'manipulate' than on Exynos chips?

The U.S. S10 Sprint 5G version can be rooted. The U.S. S9's just got root not too long ago. As for the other U.S. variants of the S10, root will probably never come to fruition.

That's why I ended up getting a exynos verison for cricket lol

Always research if a device has root before buying it. Also if you want them to stop locking the bootloaders for the US variants start buying international exynos models so you can have root and maybe they will notice not as many US units selling due to locked bootloaders and will stop locking them, I doubt it but you never know.

Which G800 best for LineageOS in US?

Hey all sorry for the newbness, I'm kinda totally new to android modding. I've been running a G800A for years now and love it to death, but it's just become a bit too outdated and limiting in stock form. I'm also under the understanding that the G800A is the most limiting version, as there is not even ROMs available to run anything about Android 5.1.1(?)
So I'm understanding if I wanted to go to LineageOS, my options are the G800F/M/Y. Anything I've found on these shows them all virtually identical other than the 4g bands. Would any one of these 3 be any better than the others to use in the USA? Does whatever carrier I would end up going with matter much?
Also, even more stupider questions- has anyone tried installing LineageOS on the G800A?
Last one- what about the G800R4 if I wanted to go with a CDMA carrier?
TIA for any help with this

you can only flash a rom built for your exact device...
only a 800f rom for a 800f device..
or you will brick..
( some roms are built for more then one device like the f/m/y variants)
sadly almost every samsung device sold in the usa after the s4 is bootloader locked.
so you cant flash anything.
you can get a s5 mini g800f from ebay for 60$ and start the flashing game is you love small phones.
That is what is did.
every samsung phone i get now is international or i dont buy it.

@nutpants thx for the reply. I'm still a bit confused tho- aren't US version G900s able to be flashed? Unless I misunderstood some of the stuff I've come across. I'm still on the fence as to whether I want to stay with something quite so small as the G800 (my eyeballs are getting old along with me). I think I might go with a G900 and see how it works out. But is this the same deal ie- I need to look for an international version of that?
Also, I've noticed that tons of international versions have limited to no compatible LTE bands with those used here in the states. I'm assuming there's no workaround for this as it's a hardware issue(?) How much does this affect real world usability?

first off i dont know everything, so you will have to research
https://www.kimovil.com/en/frequency-checker/US/samsung-galaxy-s5-mini
this is a good reference but i just found it so it could be very wrong also.
( it looks like it is not very good with all the variants so its not to be considered the last word)
while i have not looked at every rom posted here ( and there might be a usa at&t s5mini xda page someplace) i don't remember seeing any rom for the g800a variant of the s5mini if it does not say g800a it will very likely not work, and will brick your device if you try.
(https://forum.xda-developers.com/t/rooting-the-s5-mini-from-at-t-g800a.3124674/
its not looking good for your g800a device at all )
i have a g900w8 (Canadian variant) and i can flash anything that the international version uses, but it has all the bands that i usa uses for the most part. (best of both worlds) but i think the usa model (v, r4,p) has a locked boot loader so it is not easy to flash roms.
( i think there is a way to do it, but i never have as i dont but bootloader locked phones)
the s7 and older Canadian phones from samsung are all easily rootable , most can be flashed with international roms, but (dont quote me on this) they use mostly the north america popular bands for lte, hspa, etc.
if you are looking for a newer phone dont get the g900 s5
get the s7 g935w8 canadian phone its about the same size, must faster, better battery ( but you cant replace it, MUCH MUCH better camera (ive had nothing but problems with the s5 camera) and ive found them for about 150$ used in great shape.
if you use data a lot then you want lte to work if you are just going to talk, then the gsm bands are good enough. ive used Canadian phones in the usa plenty and have no serious issues.
but i just got the s5 mini g800f from ebay and im still setting it up so i dont know how well it works yet.
short answer, usa phones are much much harder to root if at all, fewer roms, international phones are much better for all that but may not work well in the usa, canadian phones might be what you want to look at
(my Canadian s5 g900w8 still have support for the latest lineage os 18 )
before you buy check if the phone is supported by lineage os
https://download.lineageos.org/
if it is, then you can root, flash roms and very likely have unofficial roms for years to come.
or you can search xda, but as you can see, the s5mini is all but dead here and developers are not working hard to improve the roms we do have. in another year this place will be a ghost town.
btw i have canadian s4, s5, s7, s4 mini, s7 , s7 edge, note 2, note 3, note 4, mega . and have been very happy with them all. i have a few usa devices (s5 active)but i cant do anything with them. so they sit on a shelf. ( not that any of them do much but the hobby of flashing the newest rom and trying it out.
