I bought an ATT frequency compatible NS (from negri) before it was available on ATT. Everything works as expected on ATT. However, the other day I removed my SIM, did a factory wipe, and then rebooted back into the bootloader and noticed that it reported "ATT" as my network even without the SIM installed. Does this mean my phone is somehow locked to ATT now? I don't care for my personal use but when I end up selling this thing later my expectation was that the next owner could use whichever frequency compatible carrier they choose. I don't have a way to test this with a different SIM. What's the deal here?
If you bought it from AT&T then it can only use AT&T's data networks. T-Mo and AT&T both use SIM so you can switch them out, but only shfor 2g/edge and voice.
That's just carrier info, if it wasn't a Google Nexus phone it would have influence on the phone. There's no downside of having a ATT in the bootloader carrier info.
Some ppl spread rumors that only "free", eg EUR (for Europe), phones get updates via Google, but it has yet to be proofed.

I said where I bought it (negri electronics) before it was even available from ATT.
The 9020a is frequency compatible with ATT, Canadian carriers, some others elsewhere in the Americas, and will do 2G/gprs in nearly every region.
My question was about the phone reporting ATT as the carrier info in the bootloader w/out a sim. Phone has zero relation to att other than it happens to support UMTS on the same bands.

I realize this from reading it everywhere. I just find it odd for att to show even with no SIM. Maybe it just reports whatever the last installed sim was?

The carrier info is independant from your last SIM card. Atm there's no hint to what the carrier info in bootloader is used for. For the European version (VDF, O2, EUR) you can change them around as you please via Odin w/o any effect on your phone.

If I understand that correctly: Any Nexus S, in its AT&T version bought at any Best Buy store in the USA is 100% SIM unlocked, correct?
But, what about the Operating system itself, Android: Does a Nexus S AT&T version bought at a Best Buy store has the pristine original version of Android as Google intended, with all its features (and describes on www (dot) google (dot) com/nexus/#/tech-specs ) ?
I have read of cases that, for instance, Nexus S AT&T phones from Best Buy had its tethering feature disabled ? If so, is this a tinkering of the OS by the carrier or store no matter the SIM (i.e. if I put in a SIM from my country's carrier, it'd still have tethering blocked)? or this presumed "disablement" of tethering is SIM/carrier dependent (i.e., not an Android alteration per se)?
Any comments on this are well appreciated. I plan on buying soon a Nexus S on Best Buy during a next trip to the USA. The phone will be used in Mexico where my carrier uses the same frequencies as AT&T or 3g.
Thanks in advance.
Hi!
Thanks to VZW deals on Google Pixel, eBay is currently full of listing for brand new Pixels for less that $600. Most sellers claim phones to be factory sealed.
Question is: Can I buy this never opened Pixel and successfully activate and use overseas?
Thanks for your wisdom!

I didn't receive my Pixel yet, but I bought an unlocked device from google's website. I did talk to a seller on eBay who has many Verizon Pixel phones and he claim that they are unlocked. Another thing he mentioned that these phones may have Verizon's bloatware apps. So if phone you are trying to purchase is unlocked, then it should work, but check the GSM bands if they are compatible with your carrier.
All Pixel phones are unlocked (we're not talking bootloader unlocked) no matter where you get it from. But good point in checking GSM bands to see if it's compatible in your country and carrier. As for bloatware there are only 2 apps from VZW and you can delete them easily.
So, no need for first activation with vzw SIM or something like that?

No need. Just take it out if the box and put your sim in. I bought mine from best buy and it's technically for Verizon but I just took out the Verizon sim that was in it, put my T-Mobile sim in and booted it up.
If you plan on using it overseas I suggest you unlock the bootloader and flash the international system images.
The backstory.... Preordered an ATT Note 7 and had many headaches with delivery / billing. I am now living with my old Note3 using Goggle Voice/Hangouts because of my weak signal (all carriers) at home. I'm using a pre-paid Straight Talk plan when away from home.
I've been waiting patiently for the S8+ and now need to decide between AT&T and T-Mobile for a GSM phone. I plan on paying full cash price and having it unlocked to use a 3rd part prepaid plan (Straight Talk or ?).
I considered a factory unlocked phone (Best Buy, May 9th??) but I am told that those will also have a locked bootloader. Up until the Note 7 I always ran rooted with custom ROMS. I became a big fan of Samsung Pay which I think also means a locked bootloader with no root is needed. Of coarse, bloatware sucks. I had good luck with Package Disabler Pro on my Note 7. I will be using my Google number, if only for forwarding to another number. WiFi calling is a must one way or another.
My Note 7 from ATT let me run Mobile Hotspot at the same time WiFi was enabled. This made it easy for giving my Android head unit in my car Internet access. The T-mobile version at the time needed to be turned on and off.
I'm leaning toward T-mobile only because of my bad blood with ATT. ATT coverage is marginally better in my area.

Yes and also if the T-Mobile version is going to have an unlocked bootloader, flashing T-Mobile firmware should allow you to unlock it through the OS.
But it's highly unlikely it will have an unlocked bootloader, although T-Mobile have supported it, I don't think it's happening.

I've heard that the bootloader on those phones is also locked, but not from a real good source of info. I've also heard international versions do not have a locked bootloader and do not support Samsung Pay. They also do not support CDMA (which doesn't bother me at all).

I'm in a similar situation and my first concern is what bands both phones support. Online it seems AT&T covers both GSM providers perfectly. The info on T-Mobile and its bands is extremely lacking. My second concern is the process of unlocking either fully paid off phone for use on the other. I think I can have TMobile unlock it for me but I'm not sure how it works with AT&T. The easiest solution is the unlocked version but thats not even got a release date set in writing anywhere.

As long you are flashing official firmware from Samsung nothing will break. Knox will not be tripped and Samsung Pay will work.

It is my understanding that all US (Snapdragon) phones cover all bands, including CDMA. That means you could even take an unlocked AT&T phone to Verizon. I'm not used to that! It even has LTE-U which TMo is supposed to be soon supporting.
I am an ex AT&T customer. They unlocked my Note 7, and again with the replacement, without issue. I seem to remember there was a wait period at first. 7 or 14 days?
The thing I'm considering is also the VR incentives for pre-ordering. I can tell you AT&T messed up my Note 7 pre-order. They shipped it on the release day by a slow method. I ended up going to a store and buying one outright and returning the unopened one once it arrived. That caused a billing nightmare that I had to call them every months until I finally turned it in and closed my account.

You're missing what I'm saying... There will be no unlocked bootloaders on any Samsung S8 phones for the USA. You cannot get one from carrier or factory.
I think you may be mixing up Bootloader unlock and Sim unlock....

I do remember that it was a story about FCC approval of the factory unlocked (SIM) phone. Keep that in mind that it may be the unbranded, factory unlocked phone only, but the article did say they were all the same. The locked carrier phones may not be so flexible.
Other things I've found.. Best Buy SIM unlocked does not get the incentives. Best Buy, and their cheaper price, does not seem to offer a T-Mo phone.
The VR incentive is attractive to me, but is not a must have. At this moment, until I can find out for sure if Samsung Pay will work on an international version, I am leaning towards a T-Mo pre-order. But that is me and my preferences YMMV. I have a major dislike for AT&T.
Looking for where I read it. In the mean time this may be interesting to you.

You're correct that it seems T-mo info is evasive.
Hello,
I would like to know, if it posible to buy the Galaxy S8 from the samsung web page (att version), then unlock it and after that flash the unlocked rom flashing it with odin.
Can someone help me?
thanks.
Just ordered the 955F from Clove...
I'm hoping that missing bands won't hurt my AT&T usage much. Or any prepaid sims I may throw in there.
Will see if the 955U info comes out before my phone, and will decide if I want to cancel.

I have an S20U now that is unlocked. What I love is that I get the updates faster it seems (although, the S20 has had way more updates than normal). I am thinking of getting the branded Tmobile one, I have never had any issues using their software and it seems to work better on the network. I do not honestly care about "bloatware" as I will at least be getting a 256GB model.
Anyone have any experiences either way?
I don't have any experience with TMO specifically, but what I do know is that typically the carrier branded devices get their updates WAY fast and more often than the Unlocked ones. I'm in the same boat, I don't really care much one way or another about the bloat. If I don't like it I uninstall it if I can or at the very least disable it

It is my understanding that the unlocked one can be used in any country and any network. Just switch sim card and you are done. The TMobile one, may be locked until you pay off the device. You also don't get the bloatware with unlocked (one less thing to Uninstall if you don't care for it).

There are 2 "Kinds" of Unlocked, you're referring to SIM unlocked, the other is the U1 devices sold by Samsung. Which I suspect what the OP is referring to

That used to be true, but not for the last couple of years. The unlocked US Note10+ (N975U1), for example, has gone through 18 software releases in the 12 months it's been out. Many of its updates came out within the first few days of the month, and included that month's Android security patch.
T-Mobile has been lagging for the past few months in its updates for both the N975U and the N975U1, but you can manually download and flash the latest unlocked software immediately.
Also, it is my understanding that Tmobile tweaks it's cellular radio's to perform slightly better than the unlocked version of any phone used on it's network.
From my experience, AT&T, the branded phones have the extras like wifi calling and VoLTE enabled and the unlocked ones don't. Some of the video call features are missing. I wouldn't have a problem with the bloatware but AT&T seems to force it back on and there is no way to remove it without root (which i don't do anymore). This has been my experience from Note 5 , 2 of the 7's ,note 8 and the note 9 I currently use, all have been unlocked.

Unlock has free caller ID builtin, Tmobile you have to pay for it. Unlock has no Tmobile branding or bloatware. Unlock version is easier to bypass tmobile hotspot apn, and usage limits
T-Mobile version has video calling on the phone app, unlock use to, but not anymore. There might be a few more things but I can't remember right now.

This simply isn't true with the Samsung phones. I have had both and there definitely is no difference in connectivity in either data or calls between unlocked and carrier version.

I think he's referring to carrier aggregation. I don't know if it's a thing licked phones have that unlocked don't. I always go unlocked (so the phone feels like it's mine, lol) and can't say I've noticed a difference.

Thank you for your post. Does the Wifi Calling on Tmobile work on the Unlocked phone? I am looking at buying the unlocked 512gb model but have to have wifi calling when I am traveling internationally.
Does anyone know if the stock firmware can be flashed on any device if it's factory unlocked? I think the answer is yes, but just want to make sure before I purchase one used. I know your can flash the carrier firmware so I assume you can do the reverse.

Yes. and if you follow a few of the guides here you can "unlock" video calling and RCS in Samsung messages as well. And if you are really creative, there is another guide to expanding bands and tweaking receiving antennas
And the last question, if you buy the U1 unlocked, you can flash carrier firmware or unlocked firmware either way all you want, but keep in mind going from u to u1 firmware requires a wipe.
The old "unlocked" was slower to get updates is only true if you wait for Tmobile to release it. If you use Frija and Odin, you can pretty much get it the same day Samsung releases it. I'm too impatient to wait for Tmobile to "get around to" reviewing it and re-releasing what Samsung released weeks before.
Most of the "negatives" of having unlocked are long gone at this point and it tilts more into the positives.

U and U1 have the same radios in them, they are made specifically for the USA market. Depending on what carrier sim card you insert those bands for said USA carrier will be made available for the user. No need to expand bands. The technical specifications of the U1 and U models are listed on samsung USA website for cross referencing.
Anyone successfully using call recording feature on either version? Still looking for my U.S t-mobile variant..
T-Mo non-unlocked Samsung phones (maybe just the Note 20 Ultra though since I haven't been with Samsung since the Note 3 lol) have a bunch of issues. They're about one month behind on updates when compared to all of the other companies. Additionally, I saw someone mention that they have better mobile data quality. That is also true... I found that out once I manually switched to the Android 11 beta as my 5G speeds went from a constant 130mb/s down to 0.5 - 2mb/s without the firmware being specifically from T-Mo. In my settings, all of the mobile connection stuff is exactly the same as it was before...
Also, I don't have voicemail support. Yet another T-Mo problem (but you can easily add Samsung as a possible cause of that problem too)... Had to switch back to the Google Phone app just so that I could get old-school style voicemail (where you have to call your own phone number to get in).

This hasn't worked for me either. It's starting to seem like Samsung pushed some of their development onto the phone carriers now lol.
Hey Samsung, why not just leave Android alone when you get it from Google so you don't have to cause so many problems with your own, customized (ad filled, feature removing) version moving forward? Heck, I've already had some problems with a bunch of your apps and have gotten zero help or answers from you guys. That's the reason I've switched back to a bunch of Google apps, however, half of those didn't even work on this phone!!! But I messaged Google about these problems as well, and you know what? They fixed ALL OF THEM within two weeks.
I'll definitely be buying from a different manufacturer moving forward. Even more so since there's rumours spreading around online right now that the Note 20 was the last Note phone to be released since the upcoming S21 is going to have stylus support...
The difference between unlocked and t-mobile is that unlocked gets its updates directly from Samsung and is not branded.
While t-mobile version is branded and you receive the updates from t-mobile and not from Samsung. So delay or longer waiting time on updates would happen and maybe even won't get few of the updates.
Since t-mobile has to release them, which take longer time.

I own an SM-S908E/DS that apparently is loaded with the firmware from Chile. The global S22U supports a lot of the AT&T bands, though there are some differences.
When I went to the AT&T store to activate the S22U, they told me that they can't register the phone's IMEI.
For now, they registered my S22U phone's new SIM with my previous OnePlus 7 Pro's IMEI. I suspect that I may not get full features (like, connection to 5G) using my old IMEI.
Has anybody experienced this with AT&T? I can't believe I would be the first person to experience this.
Is there a way to get my SM-908E/DS properly registered on AT&T as an S22U?
Did you buy it new or used?
If you were actually able to get your device activated on AT&T they WILL end up kicking your phone off the network at some point. AT&T has blocked international S22/+/U models on their network for basically no reason. This version is not on their weird whitelist of devices which means that they will not allow it on their network.
Maybe when S23 line releases in about a month, they will allow these models since it seems that international versions of the S10-S21 line are allowed on their network. It could also already be on the list but not on that outdated document.
If it is not on that list, you will find out soon enough when your line gets suspended and you have to call to reactivate it.

I bought it brand new, off of a eBay reseller who had very high ratings.
The Samsung box was sealed, and looked totally new (identical to my wife's US version), so I know it should be legit.

It should be legitimate then. Even so, buying off of Ebay can still be hit or miss.
If they activated the new SIM, then you should be fine for the most part.
The list that nnighthawk posted is AT&T's list of devices that were tested and approved for support purposes. That doesn't mean it won't work. However, if you have connection or service issues, they will tell you that you are using an unsupported device and therefore they can't help you.
Also, from a network security perspective, US carriers (and many non-US) don't like it when people want to use devices that are not tested on their respective networks. Untested models with firmware that is untested/unapproved are potential security risks. Carriers don't make money by selling devices; they make it by selling services. Any potential network breach could cost them billions of dollars in revenue and customer trust. The latter can lead to litigation and government investigations, which costs even more money.
