On ATT buying Tmobile version

Hey, sorry if this is discussed in another thread, but I read a few and couldn't find the answer.
I'm on ATT, but I want to have an unlocked bootloader, so if I buy the Tmobile version for full price online can I just put my ATT sim card in there and it will work? Also will I be able to get LTE?

I don't believe it is that easy. YOu either need to get Tmobile to Unlock the phone so you can move it to another carrier or pay someone online to unlock it - I don't think you can just switch sim cards unless you have first unlocked the phone. (I am not talking about unlocking the bootloader - that is something else entirely - TMOBILE probably won't lock theirs like ATT does - but the phone itself is locked to the carrier until you get it unlocked)

Well if I buy it from Negri online it says it already comes unlocked. So since it is unlocked then is it able to be used on ATT, or is it only unlocked for Tmobile?

If you buy it from TMOBILE it is probably locked but there are a bunch of places you can buy unlocked Note 3's - plus yiou can always unlock the MOBILE NOTE 3 either with TOMOBILEs help or thru an online service.

Yes you should. It has the bands to support it. Keyword should until someone with device on hand confirms it.

I plan on walking in Wednesday afternoon to a T-Mobile store, purchasing two Note 3s at full price (one black, one white) and then immediately using them both on AT&T. Actually one phone on AT&T and the other on AIO Wireless (AT&T network).
My history is with Verizon and Sprint so I'm not 100% sure about all the specifics of SIM cards.
I'd imagine I'll ask if its SIM locked, hopefully they say no and I'll be on my way. But if it is carrier SIM locked, I just ask them to unlock the device? Is this normal? Does anyone see any issues with this?

i dont think they will be selling the device alone at full price anytime soon..

i ordered mine from negri and overnighted it so i am hoping to get it wensday/thursday. will post back with results but if it is unlocked fcc confirms which bands it works with so there should be no issues at all.

Yeah I believe in-store, T-mobile requires you to have service with them to buy a phone at full price (even pre-paid service). So you'd have to signup for the cheapest one (I think like $30/mo), buy the phone, and cancel right away. However they still charge you for the first month.
However they should unlock it no issues (though you may have to call - don't know about t-mobile).
This was my experience at a T-mobile corporate store, you may have better luck at a franchise store.

Anyone know where to get the Tmobile version in white? Full price. Negri seems to sell the blk version only.

Hi. I think these will precisely answer your questions about 3G/4G compatabilities between all US models (including ATT and TMo) for use in the US and abroad. A lot of people seem to think it has immensely clarified their concerns. It's partially based on FCC filings as well as documents from T-Mobile so is as official as it gets.

Just bought a 910T on Swappa

Phone is already rommed and rooted. Hope it is unlocked for ATT. I decided to buy a T mobile device to use on ATT rather than an international device. If it does not work on ATT I can resell it for $675 Won't have a shortage of buyers. I expect it can be used with ATT LTE bands as well

As best I can tell the n910t supports both Tmobile and At&t. But you'll probably need to unlock it.

[Q] Best buy "unlocked" galaxy s5: unlocked bootloader?

I've been an iPhone user for 5 years now. 3G and 5 versions. I am tired of iTunes I would also like to tinker a bit with my next phone. . I have used Linux as my main desktop os for a few years.
Anyways, I'm on a grandfathered unlimited data plan on att. My iphone 5 has no working power button, the mic is defective and the battery is worn.
I work in construction so i was considering the s5 for its dust rating and removable battery.
I spoke with tmobile today and they told me that any tmobile device, even if bought for full price new on amazon or best buy would be locked to tmobile service. They informed me I would need service with them in order to unlock. If that's the case it rules out buying a tmobile version for the unlocked bootloader.
Does the unlocked version from bestbuy come with the unlocked boot loader?

To clarify I meant the model listed as "Sam G900"

I'm pretty sure he's just going off what best buy says for the model.
I too am wondering this question. Very disappointed in the new S6, thought it was going to be "the next big thing", turns out they just want to be like apple now.
Side note, where would u recommend buying an unlocked bootloader S5, that has LTE capabilities for att? Or does that not exist in the US? Been searching but coming up empty handed.

I don't have the phone I am referencing. Like mentioned earlier, it's just the model number off of best buys webpage. They have the g900a model and a Sam-g900 for sale. They only sell the tmobile prepaids unlocked at a higher price point.
Is there a reputable online seller of new or refurbished unlocked tmobile versions?
I don't know if I wanna gamble buying used.

Buy a 900f from ebay. There are tons of reputable sellers there, just look at their feedback score. All qualcomm models support all lte frequencies, however they're not activated by default. There's a guide in general or q&a which shows how to activate all freqeuncies

Does the 900f come with unlocked bootloaders? Is there a way you can identify if they have an unlocked bootloader without physically checking the phone just don't want to spend hundreds of dollars and kinda get stuck with a phone that's not what I wanted.

I just purchased an unlocked GS5 G900T (Tmobile version) from eBay yesterday, and should have it by the end of the week. I've purchased my last 3 phones from eBay, and all have been true to the ad, and in excellent condition.
You do need to study the photos closely though, and make sure the seller has good feed back, and a lot of feedback (I never buy from sellers who have only a few ratings and/or using a new account).
I got this phone to use with ATT and wanted an unlocked bootloader. Kinda wish I knew that you could activate the frequencies on the 900F though, as it seems like most of the development is for that model. Oh well, as long as I can root and have a few choices of ROMs, I'll be happy.
I'll probably be using some sort of stock based rom on this phone (for a while at least).

I did not know that T-Mobiles Galaxy S5 Came with unlocked bootloaders. I am just going to get one from them since T-Mobile and ATT run on basically the same LTE Basebands and LTE will not be affected as much as the international version when i'm on ATT's network

didn't read the rest of the replies but cricket...they sell it with unlocked boot loader, and you can sim unlock after six months...but they are owned wholly by att so you'll have att's reception and reliability. Of course your unlimited data would be history but crickets rates are significantly lower than most other mvno carriers
Edit: the model no is sm-g900az

I called bestbuy.com customer service. The customer service agent was no help. No additional info than what's provided on the webpage (actual samsung model # is what I was looking for).
She transferred me to their technical support department. The gentleman spent about 5 minutes or so searching and couldn't come up with anything more.
I was told to call an actual best buy store and speak with their mobile department.
I called later today when best buy opened up. Sat on hold for 8min before an actual human being answered the phone. They too were no help. The conversation went like this...
Me: do you know which model of the g900 the sku 5760005 is referring to. . The listed model number Sam-g900 with that sku# is not an actual samsung model number.
Them: it's a g900.
Me: no you do not understand, g900 should be followed by one more letter. Is it a g900a, g900t, g900v, g900f, g900h, etc?
Them: it's a g900. What provider do you have?
Me: I'm on att but probably going to tmobile soon.
Them: we don't carry tmobile. I have a g900a. It works good. (they have the prepaid tmobile s5 on their website).
Me: nvm. Thanks have a nice day.....click.

Help with s7 edge carrier

Hi guys,
I live in New York and I'm using Cricket wireless services (they are using AT&T's antennas),
I want to buy the s7 edge but its lock for the "big" carriers: verizon, at&t and sprint.
Is there any way that I can buy the phone unlocked from somewhere, or buy the phone from one of the carriers and unlock it so I can use it with Cricket?
Thank you!

You can buy it from AT&T or T-Mobile and unlock it we can confirm that as we've unlocked many for customers to use on other networks
but if you want to just buy it unlocked maybe check online you can buy a factory unlocked version online or at the samsung store

I bought a LOCKED Sprint S7 Edge on eBay (they don't blacklist locked devices)...... I paid $6 thru eBay remote unlock service and the device has worked like a charm for three past 8-9 months.
Unlocked on eBay are usually a little cheaper.... if sellers account/device is paid up then all you'll need to do is put in new carrier SIM to unlock. (Mine wouldn't work so I ordered that remote unlocking service.... guy was amazingly fast, professional and very helpful.
Good luck!

Activate Band 71 by Firmware Switch?

Hi there, I'm looking at buying an S10+ on eBay, and I see quite a few from AT&T (unlocked) that don't support Band 71. I'm on T-Mobile, and was wondering if I can install the T-Mobile firmware, since all of the G975U models supposedly support all the US firmwares, correct? If I do install the T-Mobile firmware on one of the AT&T unlocked models, will it activate Band 71? I live in a city and don't really need Band 71, but I do travel frequently and was just recently in an area of Band 71 coverage that my current phone LG G6 couldn't support, so I'm curious.
I'm using the following page for reference on which firmwares/phone models support which bands:

Thanks, LimeyBastard. So just to confirm I understand this correctly, all of the Snapdragon/US based models have the exact same hardware, which supports Band 71, but only Tmobile and US Cellular activate Band 71 support in the firmware? Therefore, simply flashing the tmobile firmware onto any G975U unit will result in a phone that can use Band 71?
The ATT phones for sale seem considerably cheaper than the tmobile ones for some reason, so this seems like a good way to save money.

Excellent, thank you! As it turns out, there's also a flamingo pink phone that is only sold by AT&T. I'd love to use that on T-Mobile. Of course, I can without Band 71, but now if I find myself stuck somewhere in the country, I might be able to have a pink phone to ward off the wolves! Haha. Now I just have to see if it's easy to unlock an AT&T carrier locked phone.

Hi Ace42! I don't need the ATT variant, it just so happened the cheapest model I found on eBay was an ATT variant, so I thought I could save money that way. I'd be perfectly happy if I could find a U1 variant, or at this stage any of the unlocked carrier variants. It seems unlocking these phones isn't a guaranteed thing yet? There are some really cheap ones from Sprint.

On this subject, does anyone know if these 3rd party unlock services are reliable/safe? I hate to spend money to unlock my phone, but if it costs $25 and I can use my phone on another network, I suppose it's worth it. I believe I can request an unlock from the carrier in many cases, but if they turn me down, I don't want to spend money on a phone I can't use, as there isn't currently a DIY method to unlock the G975U, correct?

I've used ATT's device unlock multiple times in the past. The only issue is that requests are denied for no reason, which means resubmitting your request. You don't have to be an ATT subscriber (T-Mobile user).

I know this is an old thread, but were you ever successful in enabling band 71 on the S10?
I am curious as to doing the same thing on an S10e - which also has a US and an international version. My main reason for wanting to do it is not cost, but the fact that the S10e comes with dual-SIM support, whereas for some insane reason, the US version does not. It seems to be that many of Samsung's US phones drop 2-SIM support.
