Has anyone used the SGH-I257M on US AT&T?
As I understand, it has the bands for multiple networks. The reason for asking is AT&T is dragging their feet.
Info I got from AT&T was that it has enough roll outs for Christmas and are not going to bring out the S4 Mini until January. My contract is up, S3 & S4 are too big for a pocket, I ditched my S3, I'm using an S2 clocked at 1.7 and gutted, nice phone, but time for a new toy to play with. I'm tired of waiting on the 'Mini', but flashable US Basebands will be unavailable for some time so I'm hoping someone has done this. More specifically meaning the 'non branded' SGH i257M and a functional LTE band 17. TIA

If you get an unlocked SGH-I257M from Canada it will work for AT&T with LTE. I got one as an early Christmas gift for my girlfriend and it works no problem. I just put her 4G microSIM from her old phone (Pantech Burst) and set it up. The only thing I had to do was add the APN for AT&T 4G. Also, I believe it was the ChatON app that would not work in the US but it wasn't important.
EDIT: Also, a question I was thinking of as well is, if when the AT&T version comes out (or the firmware at least) could the AT&T I257 firmware be flashed on an I257M? That would minimize any issues from the phone's software..

I appreciate the reply. That is good to know. Yeah, ChatON is of no interest. As for flashing, There are multiple reports that the 9195 ROM flashes OK on the M's, 9195 also adds the FM radio that is not given functionality in the M's but restored with the 9195 OS so I would assume the AT&T version should be no problem provided AT&T isn't pulling another non standard hardware version as they have in the past with some phones. (FCC filings don't indicate that) AT&T seems to have developed a phobia in recent years about their phones being retrofitted with new OS's. Also likely they are waiting for 4.3 or a Knox implementation in the deluded belief that it is secure. Thanks again for the heads up on function, looks like the price from Canada isn't too bad right now.

Hi. Thank you for sharing this. I actually just bought a Canadian i257M as well and now I'm waiting for it to get shipped to me. Question; do the samsung media apps work while in the US? For example, media hub, video hub and music hub? I ask because i used to own a GS4 from att and I purchased a lot of media on those apps and would like to continue using them if possible on the GS4 mini if possible.
Much appreciated!

You may have some disappointment, Samsung has switched to 'Samsung Hub' on the new phones, replacing the older Media hubs and interoperability suffers a lot. T-Mobile offers a Media Hub for their new phones, AT&T may as well since the Sammy app's leave so much behind. It's going to be a wait and see I suspect. With luck AT&T will have Media Hub apps instead of the newer Samsung replacements and all you will have to do is wait. It seems quite a few people have money tied up in the old system and that may keep it alive.
But other than that, all you need to get on line is write your carrier APN. The phone is turn-key as it is. I just got an 'M' and after gutting the OS, dropping in an APN and editing the Build Prop a little (not needed) it works great on US AT&T.
There are more and more of the i257M's turning up recently in the States and hopefully someone will be able to clarify the Media Hub issue more for you better than this.
Where are you guys getting unlocked 257Ms? I can't find anything on ebay and the internet suggests canadagsm may not be reputable.
Hi...wondering if you can help given you are on AT&T 4G LTE. My i257M arrived today from canadagsm and it appears rooted. Surprise, but maybe good. BTW...canadagsm handled this order ok, not great and not responsive, but they did deliver. Anyway so far so good, but I am also on AT&T 4G LTE and wondering how to edit the APN? Why? Right now I am only getting H+ connectivity. So wondering if there is a way to do this voa the hardware or only via software? Also, can you post the Build Prop? Lastly, due to rooted phones being disallowed on my company network I can only use a stock ROM.
Lastly, as I write this I ended up going into the boot ROM and which is not CWM and for the last 30 minutes and selecting install the volume up, the screen shows DOWNLOADING, DO NOT TURN OFF TARGET!! However, I am not aware I am downloading anything and seeing this screen is a bit scary. I may mess with this a little more by the time anyone gets a chance to respond, so we will see.
Thanks in advance, malloy0

I just made a thread abouu this. Just picked up a i257m and on every kind of combination of rom I'm stuck at only h+. I spent a few hours on the phone with cs to figure out why after googling a few other cases similar to ours. Turns out att doesn't support unlocked phones so the account isn't setup to push lte. What others have done, and what I'm going to try to do tomorrow is pop the sim into an att phone thss can do LTE and set it up and switch back and it should follow.
Att were assholes and wouldn't setup a device on my sim temporarily to prove to me LTE worked on my account. We popped my dim into a display g2 that was getting LTE, and got only h+. So I told him to pop the display sim in mine to see if I can get LTE, it only triggered the LTE option in the settings but never popped up saying it was getting any.. Hmm
Edit: got lte working with a new sim! All works perfect on att!

Just wanted to throw in an update, I took the risk and ordered a 257M from CanadaGSM. Minor hiccup with the webpage didn't forward my address to their credit card processor, but they sent me an e-mail and a paypal invoice, and shipped out the phone the same day I paid. Quick customer service response time via e-mail, too (as in within a few minutes). It works great on Straight Talk, but I don't live in an LTE area so I can't test that till this weekend.
It rooted easily, and now it's running PAC.
Edited to add some information.

Good news for CanadaGSM...I too was leery, but after a few emails and phone calls they stepped it up big time. For now I have retired the S5 mini in favor of a Nokia Lumia 520 for $65!! Woo-eeee!! It's a super smooth phone. Apps are a little limited, but still have found everything I need except "stay awake" with charging. as for the S4 mini on LTE? No luck at all and expect one of two things...1) it's a locked Rogers phone and I am on AT&T, thus they will not allow LTE or the phone is not truly LTE capable.

Use the 9195 root method and 9195 roms, same phone just different lte bands.
What I did was use Odin to flash recovery then flashed the root kit then used the unlock app from the play store to be able to run att. Then I flashed my liquidsmooth and havent looked back!
I used Odin to flash philz touch recovery, then flashed the PAC nightly. Only issues so far are ROM related, like launcher preference and battery drain
Sent from my GT-I9195 using xda app-developers app
First and foremost, I'm a noob.
Anyways, I'm giving this whole Android thing a go for the third time. I had an S7 and an S7 Edge, both were great phones but they were also carrier versions. I've owned pretty much everything Apple and coming to the realization that Apple is dropping the ball. It's time to switch it up.
I ordered an International Unlocked 930F Note 7 and I'm currently with AT&T. After researching, I'm aware that I'll be losing a few things like Samsung Pay and VoLTE. Few questions I have: When the Note comes in the mail, shall I remove the SIM out of my iPhone SE and insert it into the new phone? Or go to an AT&T store and ask for another SIM?
Your feedback/suggestions are greatly appreciated!
Someone will correct me if I am wrong but I don't believe you will lose Samsung Pay. It should work. And yes, just plug your SIM (if its a nano) and go. I plan on getting the same phone and I had the S7 Edge international version and it worked fine on AT&T. I never tried Samsung pay though.
Thanks for the quick reply.
Not too worried about Samsung Pay, as I don't even use Apple Pay. But the VoLTE is what I'm mainly concerned about.
Also what about visual voicemail? I understand it can be downloaded from Google Play, but will it still work and keep my same greeting, etc..?
Brings me to next question: Samsungs website offers the micro SD card as a free gift when purchasing the phone, do you know if they honor purchases from eBay and/or international devices?
Yeah I don't use Samsung pay either. Not sure about VoLTE.
Visual voice mail works fine. Just download the app from the Play Store like you said but not sure about the greeting. Don't know if that stored in the app or on AT&T's server.
From what I've been reading, when you register your phone, regardless of where you got it, you will be able to take advantage of the current promotion. LETS HOPE!
Samsung pay should still work, and so will the VVM app from the play store.
Eventually if a root/flashing method should come out for the international model which could let you flash over AT&T stuff such as HD voice. Not 100% sure on that but maybe someone else can verify that.
When you get the phone, go to the store and ask for a sim.
As for the free gift, it only applies if you buy it from a carrier store, or certain stores. I'm assuming the guy you bought it from already got the promo gift from Samsung. If you really want it maybe cancel the eBay order and get it from Samsung.
As far as I know you can't buy the international version straight from Samsung. If that would have been an option, I'd been all over that.
Would the SIM in my iPhone not work?
Seems you may be right, the only options I see on their site are carrier models. If you go to the promotion site though, they have an option for "other" retailers so you can try with your eBay invoice as proof of purchase.
I like where your heads at.
I suppose what I can do with the SIM is try swapping it into the Note and if it doesn't work, go to the store.

I'll pop in with a lil info for you. I use a international Note 4 on AT&T now with zero issues. A few reasons why I went with this version instead of a carrier branded phone. First one was the unlocked bootloader, since the AT&T version was locked up and still locked to this day. My 4 still works perfectly fine with a custom S7/Note 7 Rom on it. So you decide if you want it..
Now in regards to the crapple sim going into the N7, if I'm not mistaken you're going to have to get that changed from the crapple set-up. Think they need to put it back to regular data or whatever all the other phones use. You know it's always something special with crapple! I would say try the sim if no data you'll know why.
Good luck

As mentioned above, I believe Apple uses different settings for data with their sim cards. When my brother switched from a 4S to Android he had to get a new card. I also just got his LTE working for him by contacting support and registering his Sim card with the one I from a store display phone. I just took a picture of the IMEI of an S7 in store and used the "ATT Phone" APN settings. The NXTGENPHONE APN will not work for some reason when I tried it.

While I'm at the store, I'll snap a pic of the back of an S7 as well just to be safe. Can you clarify "ATT Phone" in the APN settings? Where is this located?
Go into the phone settings and get the IMEI and IMEISV
I needed both when talking to tech support.
As for the APN I used the same ones as the OP from this thread.

Just want to verify this phone works appropriately with Verizon. I see nothing on this from Verizon's website and nothing more than a few mentions in press releases. Does the lte-a work correctly? Can we access Verizon features like video calling? Does Verizon staff give you problems trying to register the phone?
Can't wait to hear some first hand experience.
wondering the same thing actually
https://opendevelopment.verizonwireless.com/device-showcase/device/7466
Looks good enough for me. I'm about to order one from clove, will update when it gets here if this thread still needs some answers. I hope volte works. Wifi calling would be a cherry on top.
Yup! Having it working on my XZ2 Compact. Didn't originally want to connect, so I flashed the OEM+OEM_Other.sin files from the US version and now I have Verizon working without a hitch. VoLTE is enabled for Verizon by default since it can only connect over LTE to begin with, but no WiFi calling. That being said and it being a dual SIM device, my secondary T-Mobile SIM has access to neither VoLTE or WiFi Calling. So I have calling set up for Verizon and Data over T-Mobile. You're able to do dual LTE standby on this device.
So now that this works with Verizon I should be able to buy the duel sim version and run both my personal At&t sim and my Verizon work sim card in this phone with duel standby? No flashing any software?

Does flashing these have any affect on DRM keys and such? I'm going to be getting a H813, but with UK software from clove so I'll need to do the same thing I'm guessing.

I believe so. H8324 is the Asian dual SIM and H8314 is the Western single sim. I wasn't checking all the bands but both phones have all three of Verizon's LTE bands supported

Just ordered the duel sim version and should have it by Wednesday. I currently have both an At&t personal phone and a Verizon work phone. Plan is to combine them both in this duel sim phone and only have to carry one haha. If it doesnt work out for whatever reason il just try google voice for my work number i suppose.

Having some issues with my XZ2 Compact Duel sim. With At&t I am only getting H and H+ connection and Verizon I cant seem to get anything to work. What APN did you pick for your Verizon sim, i have choices of CBS, FOTA, IMS and Internet.
So I have some more information that may help someone or may not. After talking with Verizon in depth about my issue with connecting to their service they have determined that the XZ2 Compact will not work on their service. Even with it being labeled as an Certified Open Market device on their own site and even being listed as Verizon Compatible on Bestbuys site and many others. They said noone there has any knowledge of the device coming to Verizon at all and were confused about it being posted on all the sites as being Certified. So i suppose it just wont be compatible lol. I guess im porting my 2nd # over to at&t and just not dealing with it because im sure as heck not going through the hassle of sending this phone and the chargers and cases back lol. If anyone has any success on getting this connected with Verizon please post, but im not hopeful lol.

I tried sending him a message but haven't heard back. I'm assuming perhaps he was mistaken about what phone this post was referring to.
I believe carol_vzw is a Verizon employee who maintains this list: https://community.verizonwireless.com/docs/DOC-2843
The H8314 is listed on here as officially supported, but H8324(dual SIM) is not. You could try messaging her on there to see if they can add the H8324, or find out why it's not compatible.
Edit: looks like you've already seen this based on the comments

Yea the crazy thing is while talking to Verizon support yesterday i referenced that post and also Bestbuy having it labeled as for Verizon as well as the phone being posted on their Showcase directly on the Verizon site lol. The support guy kept putting me on hold and said he was taking the info as I was giving it to him to another support team directly and that they were all baffled at this information as none of them had any knowledge of this phone let alone it supposedly being compatible with Verizon at all. After about an hour into the call a woman picked up the phone and directed me to attempt to put my new sim card (when i swapped to this phone i had a micro-sim from my old phone not a nano-sim which this phone needs) directly into someone elses phone that has Verizon and attempt to activate the sim card on their phone, then attempt to reinsert it back into my phone to see if the network picked up. I will be attempting this in about an hour when I see a friend who has Verizon. I will update on whether this works or not.

If its any hope, I had a similar situation when I was trying to activate my Nexus 5x on Verizon. The people in the store didn't know that it existed and had no instructions on what to do. Also my first nano SIM phone, and they couldn't get it to activate. That's when I learned to never go to their stores for technical help. But it was worth it that time because they let me keep the sim card and later I was able to get someone on their tech support number who was able to activate it remotely. It could just be that the phone is new and information hasn't gotten around internally. Verizon seems pretty bad about that.
My xz2c single sim package got lost on Wednesday by DHL ? but I'm going to be dealing with this soon
Well no luck trying to activate the Sim with another Verizon phone. It seems that the phone just isn't in the Verizon system yet.
I have a UK single sim that I'm having no service with Verizon. Not sure if it's due to the phone being from the UK or something else with Verizon maybe. Trying to flash the US firmware but having problems with Newflasher.
If I have any luck I'll post back here.
Just posting for others who may be curious; I was able to get the phone working on Verizon today. Using the sim from an already activated pixel 2 initially worked for data and calling, and sending text messages, but I could not receive text messages. I grabbed an updated sim (says 4G LTE on it) and activated it on the pixel 2, then moved it to the xz2c and currently have everything working. It's only been a few hours so we'll see if it stays like this or if it goes the way of the htc U11 and has problems every couple of weeks. I'm using the verizon approved H8314 single sim model, not the dual sim model.
Interesting, thanks for the update! I'm using an activated sim from my Pixel 2 as well. It says 4G LTE on the sim too and my model xz2 compact is the same H8314. So maybe it is the UK firmware in my case, I'm going to keep trying to figure out my drivers issue this weekend to flash US firmware and see if that helps.
Can someone help in this arena would be good to know the difference. Sammy is giving $600 trade-in on my Note 9 if I go to unlocked or I can get the same with Bestbuy carrier locked to ATT. Why I would like to go Samsung route is that it would give me time to move all my 2FA.
So if anyone has a list of carrier difference and issues pleas let me know

They are the same phones and can run the same firmware.
I would go with whatever the best deal you can get.
I thought things like video calling and wifi phone calls don't work. Hmm well that's good news then.

Can someone help in this arena would be good to know the difference. Sammy is giving $600 trade-in on my Note 9 if I go to unlocked or I can get the same with Bestbuy carrier locked to ATT. Why I would like to go Samsung route is that it would give me time to move all my 2FA.
So if anyone has a list of carrier difference and issues pleas let me know

You can actually just go research any of this in the Galaxy S8, Note 8, Galaxy S9, Note 9, or Galaxy S10 forums. They all work the same way.
Same hardware across each of the variants, but the software and the carrier will determine which features work. If you're on ATT and you want WiFi calling and VoLTE, you'll need to buy an ATT device. They check your IMEI and if it isn't on their whitelist, those features won't work, even if you flash the ATT firmware.
All the other carriers you can just flash their carrier firmware.
T-Mobile is the easiest. The only thing that won't work on TMO with unlocked firmware is video calling and RCS texting. WiFi calling and VoLTE work right out of the box.
That is what i figured searched the forums a bit but needed something concise appreciate the info!!

I am using ATT prepaid and I bought the S10 plus last year. I flashed it with the ATT firmware and I got wifi calling working. I plan to do the same for my Note 10 plus.

Cool! Someone just said that doesn't work on ATT anymore, because they now strictly check your IMEI. I use TMO so I didn't do anymore research, just figured ATT changed their system.

I have been using it just fine. I will do it on my Note 10 plus and report back my result.
Well there you go, OP. I guess flashing ATT firmware to your unlocked device still works to activate carrier features. Everything else I said is still accurate.

So right now ATT wifi calling doesn't work with Note 10 Plus but it does work for S10 Plus (and previous models). I am pretty sure this is because the Note 10 is still very new and their system needs some update. I will wait a couple weeks and see what happens.
I called ATT. They told me Note 10 is not on their list yet.
Wow thanks so everything works when flashing the firmware that's great. My wife and I use thr video calling this is great news.

Work in IT daily and easier for wife as it pops up in call.
I would use it, but I use a Google Voice number as my primary number. We used to do Hangouts video calls all the time, but not so much anymore. I guess the romance is dead.
If you flash carrier firmware to the unlocked phone, don't you basically just end up with a carrier phone? If the answer is yes, then what's the point of buying the unlocked phone?

So interestingly, there's another thread and people who are flashing ATT firmware to the unlocked version can no longer get WFC to work. They said it works for a few minutes if they give ATT an old IMEI number, but the system will automatically update to the new IMEI and WFC will no longer work. Read page four of the thread to see what I'm talking about.

There's a few reasons:
1. This year the Note 9 is worth $600 towards an unlocked model, but only $300 towards carrier models.
2. The U1 models generally maintain their value a little better than the carrier branded models. Even though it's the same exact device, that little "1" makes a difference for some reason.
3. It's factory unlocked. T-Mo, Sprint, ATT, and now Verizon all come carrier locked. Verizon stays locked for 60 days then automatically unlocks. T-Mo you have to pay it off, or pay cash up front, then wait 40 days with it active on your account before it can be unlocked. ATT again has to be paid off or paid in full up front and then you have to request an unkock and wait for the code. I believe Sprint automatically unlocks it once it's paid off.
4. I've heard conflicting stories, but at least in the past, Sprint was weird about their BYOD program. You could only bring devices with whitelisted IMEIs. That was Sprint devices and factory unlocked devices. If you just got your ATT Galaxy S8+ unlocked and brought it to Sprint, it wouldn't activate, even though it was the same exact device hardwarewise. The IMEI wasn't in their database. So the Unlocked version is more flexible.
5. That ugly ATT box. For some reason ATT will often take the phone out of the nice Samsung box and throw it in a cheap ATT box. See the USA Pre-order thread on here. There's already people complaining about that box. And I'm a packaging guy.
So you might as well get the device that's cheaper up front and holds it's value the best and is the most flexible carrier wise. If you want carrier features and firmware, you can still have them, and no worries ever about a SIM lock. Well except with ATT apparently. If you need ATT WiFi calling and VoLTE, you may be stuck getting the ATT model, from what I'm reading.
Now that said, if you don't have a trade in device, and your carrier is offering a better deal on their model...then by all means get that one.
Resurrecting and old thread rather than starting a new one.
I'm on T-Mobile and looking at either an unlocked Note 10+ which is $200 off right now from Samsung and Amazon or the Note 10+ 5G from T-Mobile. I know this is a bit of an apples to oranges thing, but what I'm wondering about is data roaming. I've heard, but have not been able to confirm is that an unlocked model will not data roam on partner networks, while a T-Mobile version will data roam. I do know that my current phone, an unlocked Essential PH-1 does not data roam, but is this true for all factory unlocked vs. carrier phones? Or at least T-Mobile phones?

T-Mobile customer here. I had an unlocked S7 Edge that would roam just fine on partner networks, in the US and internationally. Haven't had the opportunity to test roaming yet with my brand new unlocked Note 10+ but I suspect my results would be the same as with my S7 Edge.
So I switched from a ATT S9+ to the (Unlocked) Note 10+ and have had the most horrible reception on ATT. I was wondering if it's happening to anyone else? I spoke with the ATT advanced tech team and she told me that because it's not the ATT Note 10+ that it's not configured for their network. Is this true? She then help me set up a new APN which was the same as before she just added hipri to the apn type. Is anyone else having this same issue or know what's going on? I need to know before I convince myself to return this one for a ATT Note 10+.
1. did you try to check and see if there's a software update?
2. try to turn off phone and turn back on
i using unlocked note10+ on verizon prepaid no problem.
i also have a freedomp simcard, it uses the att network, it showing the same 3 bar signals like my toy iphone8 at my house
I also use unlocked dual SIM 975F on ATT. It works but I feel like the speed is slow but ironically, when I compared to a '5G' iPhone on ATT I got faster speeds - go figure. I'm trying to get them to enable voLTE . I believe we miss band 30!which is used in cities. The trade off is worth it though, for me to have dual SIM.

Yea I have the latest software. I have the N75U1. The whole reason why I got unlocked is because of bloatware and also so I'll be able to unlock and root the phone once that feature becomes available. So hopefully I made the right decision.

So based off of that should I return this phone and swap it out with the att version? I thought the unlocked had the same hardware and a little more? Sorry I didnt do my research on bands and all that good stuff.

If you bought the N975U1, then it's already carrier unlocked.
If you mean unlock the bootloader, that will never happen. And there's about a 99.9% chance it will never be rooted.

Yup. Same exact hardware.
The N975U, the N975U1, and the N975W (Canadian) are all exactly the same hardware and you can cross flash hardware between them.

I think it varies carrier and location. I just flashed the tmobile firmware which is the same for at&t and I got VOLTE ,WIFI CALLING AND ADVANCED MESSAGING back. Where I had no service I have 2 bars now.
So I'm happy now. Try it for yourself before returning

Thank you for that info that's all I needed to know because what the att advanced tech team said was that the att note 10 was specifically for their network including hardware so I was thinking it had something this unlocked version didnt.

LOL. Nope same exact device, just different firmware.
I bought the unlocked too. I really needed wifi calling since my ATT service is poor at my house. Once I flashed the ATT firmware (including ATT User Data file) I got wifi calling, VoLTE, HD Voice, Visual Voice all back. My calls are 100% better. Before flashing I sounded muffled to the people who I called & calls were dropping. Now they are crystal clear & no drops. I mainly got the unlocked for the Trade in value on my Note 9. Totally worth it.

Disclaimer: You do this at your own risk! Read & re-read the details! I am not responsible if you brick your phone
Now, all that being said, it was actually an easy process but I searched and read and read and re-read before trying anything.
I got the firmware & most importantly for AT&T, the UserData file from this thread (Read the entire Post (maybe 2 or 3 times), it's very informative:
https://forum.xda-developers.com/galaxy-note-10+/how-to/n975u-n975u1-firmware-links-t3957648
I followed the instructions from this S10 thread See POST #5 & substituted the N975U file Wording when they listed the file names for the S10 firmware:
https://forum.xda-developers.com/galaxy-s10/help/samsung-s10-unlocked-phone-att-firmware-t3912973
NOTE I used a patched version of ODIN from this thread (and not the version linked to in the S10 discussion thread above):
https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
Lastly, I am using my old Note 9 AT&T SIM Card. From what I've read, at any given time, AT$T can update their system and your IMEI might not correspond to their ATT specific list and apparently you can lose functionality. I've been fine for a week and others have been flashing unlocked phones with ATT firmware for years so I'll take my chances.
Good Luck!

Use the patched version of Odin.
Turn the phone off and press and hold the power,up and down volume buttons at the same time.
Let go once the download screen appears.
Go ahead and put all the files in the correct spot..AB to AN ,BL to BL and so on.
Once complete just start the flash and that's it. Leave the att sim in the phone through the whole process.
Done...

I'm not sure if the ATT file took.
I know I lost my apps/customizations...which I was expecting since I used the home-csc file.
Also my GMAIL app is not right, its missing the ability to set the frequency of SYNCs, which I had with the stock Gapps.
