International Note 5 N920i on AT&T

Because I hate the idea of having a neutered AT&T Note 5, I bought an international variant (N920i). It appears the LTE bands are all compatible between the two. I will let everyone know how it turns out. If you already have experience with this, let me know.
EDIT: Yes, N920i works without any modification on AT&T

When does it arrive?
Thats very interesting.

First half of this week hopefully!

Please keep us posted.

@alaskajoel Le us know if you have any signal issues.
The T Mobile S6 Edge on AT&T network gave me some issues. Calls would take 30 seconds to dial out and phone did not ring a bunch.

Will do. Should be in my hands tomorrow.

Here goes. N920i 64GB

LTE Working with attnextgenphone APN. Made a few phone calls, received one, and so far no odd problems.

I don't see the LTE on the signal bar are you sure it's on LTE?

LTE showing up on the signal bar is a Domestic device visual. International versions Show E (edge) 3G, H+ (Faux G) and 4G for LTE.
If you are still unconvinced, my service mode presently shows I am on LTE Band 4. Download speeds at 40mbps this evening. No carrier aggregation unfortunately, but I also didn't have it on my Nexus 6 or the GS6.
I purchased the phone from a seller in Hong Kong via Ebay.

Awesome! Enjoy!

Yep, just like the International S6 G920I that supported AT&T LTE

This is excellent news. How much did you pay for that bad boy? Please go to dev settings and see if "allow OEM unlock" is in the options. Thank you.

I thought I'd give this thread a small bump as I'm about to pull the trigger on an international N920I as well.
My question stems from simply being new to importing phones and having to pay attention to bands. I have bene following this thread closely, and it seems as though the N920I performs well on the AT&T network, but is it the same as if I had bought one from AT&T? I ask only because it was just mentioned that this phone does not have Carrier Aggregation.
I'm not certain what carrier aggregation is (I looked it up on google but couldn't find much to answer my question). Does this mean that it will perform more slowly on US networks?
Also a final question, if anyone is willing to answer it. What is the region-locking situation on this phone? I have read mixed reports about people being stuck with phones that they cannot use because it was not activated with a compatible SIM, and some people that say they have had no problem. I don't want to drop $900 on this device and not be able to use it.

My data speeds and reception have been the same as my nexus 6 and girlfriend's GS6 (purchased from AT&T.) Carrier aggregation allows for next generation LTE, but I have yet to own a phone, AT&T branded or otherwise, that supports it in my area. It might just be that there is no support for it in my city, but I'll be in Chicago In a few weeks and will try to investigate it there.
I can't speak to the region locking. All I know is my phone was completely sealed and worked 100% right out of the box with only putting in an AT&T SIM card.

Thank you for the quick reply. I think I'll put in an order right now.

Samsung Pay
I'm glad to hear that the N920I works on AT&T on the LTE band. I considered getting the International version. However, there is something else that I am concerned about...and that is Samsung Pay that will be coming late September. I believe carriers have to allow (or configure) Samsung Pay to work. For example, Verizon may not be supporting it, at least that's what's traveling around the net. Also when I had the International Galaxy S3 on AT&T, Google Wallet didn't work, it only worked on AT&T versions at that time. Unfortunately, we won't know until Samsung Pay is available, but I wonder if it will work on the N920I?

Awesome news. can you please tell me if VOLTE works on AT&T or if you even had the option for HD calling? Settings should be found under data options.
Thanks in advance.

For those wondering, if you use an N920I on AT&T, there are a few things you should know.
1. Since this is an international model, the signal indicators are different than what we're used to seeing in the US. The SM-N920I shows the following indicators for mobile data:
E - This means you have a 2G/EDGE connection
3G - This means you have a UMTS connection with no HSPA
H+ - This means you have an HSPA+/Faux 4G connection
4G - This means you have an LTE connection
2. Phone calls will not work over LTE (VoLTE), and, by extension, HD Voice doesn't work either. The VoLTE and HD Voice components are proprietary software that is only built into the AT&T-specific ROM on the SM-N920A.
3. The phone DOES support carrier aggregation (otherwise known as LTE-Advanced), but not on AT&T's bands. Considering that the SM-N920I is intended for retail in Australia, New Zealand, and Singapore, the baseband firmware is tweaked to do carrier aggregation on band pairs that are common among carriers in that part of the world.
So, what does this all mean? If you want a phone that has support for all the bleeding-edge technologies on AT&T's network (VoLTE, HD Voice, LTE-A), then you have no other choice but to buy an AT&T-branded SM-N920A. However, if you want faster updates, no carrier bloat, no carrier branding, an unlockable bootloader, and don't mind sacrificing the whiz-bang stuff on the network side of things, then an SM-N920I will work just fine. Put your SIM card in, you'll get LTE data on all of AT&T's available bands, and you'll be able to make and receive calls over the HSPA+ network. You're just not going to have all the latest carrier-marketed bells and whistles that you'd get if you bought a proper AT&T-branded SM-N920A.
At this point, I *should* rant about how stupid it is that Samsung refuses to sell SIM-free, unlocked versions of their phones via US retail channels. That's what forces us to go through these 3rd party importers to get the international models that aren't really tweaked for the US carriers. Alas, I'm not going to go down that road, though. It's a tempest in a teapot.

Translation: On the 920i/c, the signal indicators follow the international standard of "4G" being "LTE", and not the AT&T/TMO marketing fiction of "4G" being what everyone else calls "3.5G".
As for the rest of your points, I have to wonder how well deployed VoLTE is on AT&T (and I don't think AT&T has even started LTE-A yet, have they?)
I live in a somewhat rural area, and I'm just thrilled I have LTE.. which beats the "no signal" I get with other carriers. I don't know that I've ever experienced VoLTE. (Then again, I can't remember the last time I actually had a voice conversation with my phone.)

Oh, but why not?! We really need some more activity in the AT&T Note5 section.

Sprint G5 Unlocked by Sprint (Domestic & Abroad) will not work with AT&T sim?

Any idea why the G5 I have that was unlocked by Sprint OTA will not work with my AT&T SIM? The phone shows the "Bad SIM" icon and refuses to work. I checked the ##DATA# settings, and LTE + LTE roaming are on? Any ideas? Thanks!

I'm no expert, but I believe the Sprint network and phone antennas are 180 degrees different from AT&T.
- Sprint uses CDMA; AT&T uses GSM/UMTS/HSPA+
- Sprint 3G uses bands 10 and 1; AT&T uses bands 2 and 5
- Sprint 4G uses bands 25, 26, and 41; AT&T uses 2, 4, 12, and 17.
Unlocked or not, a Sprint phone antenna is not designed to connect to the same networks as an AT&T phone.
I know there many more knowledgeable than I here, so I welcome corrections.

Change band priority
4 and 2 are from AT&T
Put 1 and 2
And Select GSM on network preference
Open Dial 5689#*992#
Field test
Módem settings
RAT selection and select
GSM/ WCDMA / LTE Auto

@adop_19 Don't get the field test menu when typing the above code. Get "HiddenMENU' with the following;
Device Test
ELT Test
Factory Reset
Log Service
WVDRM Keybox
Any ideas? This is puzzling as Sprint swears the device has been unlocked OTA? There are others on this forum using the same device on Cricket, and thus I believe it should work on AT&T? I am at a loss? Thanks.

Yours may have only gotten internationally unlocked. Sprint has 2 unlocks. They sneakily volunteer information and assume you mean international unlock only. You have to specify domestic unlock to get it to work in the US if you unlock through Sprint's OTA. It does have the bands to support GSM in the US. Even the G4 does. I unlocked one and have it running on T-Mobile. Talk and text only since it didn't give me the APN menu then, but that's ok, it stays near wifi. If you can't get back in touch with Sprint, there are other ways to get it done without them. You'd have to PM me for that part.
Just Reread The Title. It sounds Like they didnt really domestically unlock it.

Is your agreement with sprint for the device fullfilled?

Piggy backing this thread. I've had my LG G5 domestically unlocked by Sprint. I've put in both a ATT and T-mboile sim and added the correct APNs. Calls work so it is definitely unlocked but I can't for the life of me get data to turn on. Not even 3g. Any ideas? Sprint service is deactivated so that shouldn't interfere with the LTE and data. Bands 2,3 ,4, 5, 7 and 12 are enabled according to ##DATA# LTE is enabled. LTE roaming is enabled as well in there.
In network mode I have Automatic, LTE/CDMA, CDMA and GSM/UTMS only. Currently set to automatic. I also tried gsm/utms but nothing.
In LTE discovery I noticed it found LTE band 12 for a second but just connected to UTMS with no data. Everything shows as not roaming (maybe that is the issue?! since these non sprint lte bands are considered roaming bands or something). Reception is good in the area. I usually hit 20mbps+ down in this location with the same sim using band 4.
Help please!

I have a Sprint LG G5 (LS992) and before the ZVC update, I was able to get LTE coverage in my house all the time... Now, after the update disabling my hiddenmenu app trick, I was forced to pay for remote sim unlock for the phone, and everything went great, I have full functionality, and pretty good speeds, using AT&T service now, but I don't get LTE anymore when i'm home... I haven't tried it anywhere else, that is my next move... Just wondering if there was something I missed... I set up the AT&T APN correctly from the ATT website apn settings, have gone through all the hidden menu settings, RAT Selection gsm/wcdma/lte auto, I dunno what I'm missing, other than it just wont work on LTE anymore.

Which firmwares support VoLTE and WiFi calling on T-Mobile USA?

I've been toying with crossflashing a G710PM (Sprint) to various firmwares to find which ones support VoLTE and WiFi calling on T-Mobile USA. I started with the Sprint firmware (didn't seem to support either VoLTE or WiFi calling on TMUSA), then I crossflashed to the European Pie release (didn't seem to support either VoLTE or WiFi calling on TMUSA either), then the Verizon Pie release (this one at least had an option for WiFi calling, but it appeared to be disabled), and finally the G710ULM10j GFI release (VoLTE and WiFi calling working fine so far).
Does anyone know if any other firmwares besides the G710ULM can do VoLTE and WiFi calling on T-Mobile and can be crossflashed?

Does crossflashing actually "enable" certain Hardware related features? Including "enabling" all frequency bands for GSM on a currently CDMA firmware? I didn;t think this was possible. I think I read somewhere that Tmo WiFi Calling feature is disabled even on factory unlocked versions.

I cross flashed a G710PM (Sprint model) to G710ULM (Unlocked Google Fi firmware) and so far VoLTE and WiFi calling work fine. Network Cell Info reported Band 66 for one location I checked (which the G710PM model doesn't support but the ULM model does according to their respective spec sheets), but LTE Discovery reported it as Band 4. I'm not sure which is right, but it seems that a misreport as Band 4 would be more likely than a misreport as Band 66 since Band 66 is a superset of Band 4. So I think possibly it actually enables the other bands, but I can't say with 100% certainty.
Interestingly, the bands listed for enable / disable in the engineering menu don't match either the PM or ULM models.
Edit: Forgot to mention, ULM and PM both support both GSM and CDMA. I think maybe only difference in specs is which LTE bands are supported.

AH! I've been trying to get to the bottom of this whole "what bands enabled/disabled for what firmware/carrier" thing for weeks now. Even LG is vague in their answers. Yes, you are correct, I'm finding alot of discrepency in the actual bands supported for which version all over the place. No one has a difinitive spec sheet. Where is this "engineering menu" you speak of? I'm getting really frustrated finding answers. Ya, i think the reason WiFi Calling/VoLTE are working on the GFI firmware is because TMO is one of the carriers Google Fi uses, so it has to work. Otherwise, Google Fi users would be upset a key feature is disabled. I bet if you were using the USA firmware it would be disabled. The key to my whole frustration is, like you mentioned, "WHICH" bands are supported. I have ULM.BPT firmware and am concerned if I use it with GSM carrier not all bands will be "enabled". Is this correct?

Honestly, when I downloaded the firmware I don't think I even knew enough about the regions to know there was a difference between GFI and USA. In fact, how do I check which one is installed? I looked in the version information in Settings and there's nothing there to tell me the region. It must be tucked in there somewhere? Maybe the BPT, USA, and GFI firmwares are all the same? I just downloaded both the GFI and USA releases from the LG-Firmwares website and the files appear to be identical. Maybe BPT is identical too?
Regarding the bands, I honestly don't know if every model supports every band or what the deal is. I've been happy with my cross-flashed Sprint on T-Mobile thus far, but I certainly can't say for sure if there are hardware differences that make other models not work with every band (or even if mine works with every band it's supposed to or it just happens to work well enough for my area). Most people seem confident the T-Mobile model is different, at least, but I think it's more of a mystery regarding all the others.
You can get to the engineering menu by using the built-in dialer and typing *#546368#*710# Then under Field Test -> Modem Settings -> LTE Band Selection there's a list of selectable LTE bands. I suspect, though, that everyone's has the same list (1,2,3,4,5,7,8,12,13,17,20,25,28,29,30,38,40), because that's the list I got on mine and it doesn't match either the PM or ULM model. I'm curious if yours is any different.

Ha! Thats my point! What IS the difference? Why have 4 versions if there is no difference in the firmware? Notice the updates are same for GFI & USA, so what IS the difference? Only thing I can think of is the Auto Switching software for Fi. But AFAIK when u put Fi SIM in it tells you to download the special software for that feature. Then notice the BPT & BPS have same updates. So, again, what exactly IS the diff? Notice it also specifically lists the "Product Type" as either GSM or CDMA. This is why I'm getting so frustrated trying to get to the bottom of this once and for all. All 4 are listed as ULM versions. Does this mean the 2 CDMA (BPT&BPS) will NOT have all the GSM bands 'enabled'? And vice versa. I'm going by this BTW:
https://www.mylgphones.com/unlocked-lg-g7-thinq-lmg710ulm-firmware-update.html
Above in your list of bands: where is Band 66? thought that was a major TMO band? Ya, funny how the list doesn't match PM or ULM, huh? Again, my frustration. I bet you're not accessing all the TMO bands, only the ones shared with Sprint. (or the ones "enabled" by Sprint firmware) Like you said, maybe just lucky to live in area with good TMO coverage, so it never searches for other bands. U live in large populated area? Heard about the PM models being flashed to look like ULM? They seem to be sold on Ebay, Amazon, etc. Breed was company name. In my research, came across alot of buyers who were duped by this. Most saying they were having all sorts of connection/signal issues. Which proves just reflashing firmware doesn't "enable" more bands. I could be wrong. Your saying no problems at all. Also came across alot of VZN users saying problem with activating the ULM on their network. Which doesn't make sense either! Again, so frustrating getting to the bottom of this. I KNOW i read somewhere about the specifically TMO WiFi Calling being disabled almost everywhere except on TMO branded phones. (which would explain why it is working on your Fi firmware)

I'm just as confused as you are. As I mentioned, Network Cell Info says my phone was connected to band 66, which isn't available on the Sprint model. At the same time, B66 isn't listed in that menu. But then, B41 isn't listed in that menu, either, and that's supported to be supported on the Sprint model. So bands listed in that menu don't match any model that I'm aware of. Unfortunately the engineering menu code doesn't work on the Sprint firmware, so I wasn't able to check if the listed bands changed when I flashed over to ULM.
I've previously read the thread about the TM differences. I do know from looking at the FCC filing that the TM model has a different FCC certification number than ULM, so it's plausible that it is physically different from the others. However, PM shares a certification with VM and ULM, so I *think* they're the same hardware. That's why I'm wondering if *every* LG G7 lists the same bands in the engineering menu. Maybe that menu isn't actually listing all the supported bands for the specific phone?
In any case, the PM model supports bands 2, 4, 5, and 12, which is most of T-Mobile. Band 66 is just a superset of band 4, so most any B66 tower will offer B4 (though possibly at a reduced speed). So even if I don't get real B66, and instead just get the Sprint bands, that covers pretty much everything . Only thing missing is B71, which seems to be limited to TM model (which, interestingly, shares FCC certification with the Canadian model).

Enabling LTE Bands from the LG Secret Menu?

I have a PM edition that has been cross flashed to a ULM. Someone pointed out that the ULM version doesn't officially have certain US bands like 12, which are very important for T-mobile/AT&T here. But the original PM version does have those.
I went into the service menu (*#546368#*710#) and found the bands listed under the field test mode and went and disabled everything other than B12. At first there was no service, but after a quick toggle of airplane mode, I'm connected to Band 12 (according to signal spy at least). I even did a speed test to make sure it was sending / receiving data. I was previously connected to Band 2 before doing this.
I'm not sure what this proves- is B12 only available because my hardware is the PM version? Or are the bands controlled by software? I have to admit, the service menu seems to offer all the possible bands this SoC is capable of, including B71 . That's interesting because I thought B71 is only on the T-mobile version and not available on the ULM or PM versions. Does fiddling with the service menu essentially let you enable whatever band you want on any edition of this handset?

I have a real ULM and connect to LTE 12 without issue. IIRC, your PM crossflashed to ULM will work on all T-Mobile LTE bands except 71. If you feel like experimenting, there were rumors that AWM firmware may enable band 71 although I don't know recall anyone specifically testing it.

I'm thoroughly confused now, I swapped to another "ULM" (also crossflashed from Sprint- the first had a physical defect that I returned and swapped for another), and didn't do anything to the service menu and STILL connected to the same bands according to software reporting. Bands that according to online resources, the ULM isn't supposed to support. Yet it does, and you say your real ULM does too. So obviously the spec sheets online are wrong and I have no idea what bands any of these handsets actually support or if doing anything in the service menu makes any difference at all.
Someone said another edition of this handset (european maybe?) had his menu showing a different set of bands available to select than mine, so I wonder if this is controlled via the firmware or the hardware (NVRAM values or whatever?). The service menu appears to just serve as a way to isolate bands available to test if certain ones work where you are. And on my PM turned ULM, band 71 is listed. I don't have 71 around me so I have no idea if this is real or not.
Wish there was more (accurate) information about there about how this works.

I'm on T-Mobile and usually connect to LTE 2, 12 or 66. Of those I'd say most of time 66. I've never seen a connection to 71, which I always figured meant that its not supported by the phone. If you are interested in trying to get 71, flash AWM and see what happens.

So it follows the firmware or it follows the hardware (nvram values)?

ALL g7's other than the g7+ are capable of the same bands. They are software enabled or disabled or even hidden.
If you can access ##data# from dialer and input the msl code to get to band priority then you can connect whichever you want.
If not the secret menu is needed to access the ones you need.
If the firmware did not include the band in secret menu then it has been disabled. At that point you need to access via a nvdata application like cdma workshop to enable them forcefully, but it will clear out after each restart since cdma workshops adds the band temporarily.

Well why do the bands on ulm stop at 40

The ULM version definitely does have Band 12.
How do I know? I followed this guide: https://mt-tech.fi/en/how-to-get-4g-supported-ca-combinations-from-your-android-phone/#LG_devices
I extracted the qmdl log and followed the steps to extract the actual supported bands as well as carrier aggregation combos right from the actual modem logs (which are 100% accurate, since LTE devices need to report this to the network every time they connect to it)
LG G7 ThinQ (US) (G710ULM) | 4G/5G Bands & Combos
4G & 5G Bands, Carrier Aggregation and Dual Connectivity Combinations for LG G7 ThinQ (US) (G710ULM)
cacombos.com
Here it is for the LG G7 ULM. Not only does it support Band 12, it also gets Band 17 and a wide variety of CA combos in that band.

Question Verizon 5g question (13 Ultra, sorry!)

Was wondering if anyone had any ideas on why I'm not seeing 5g with a global edition 13 Ultra on Verizon in the US? I know it's missing some of the bands and I'm fine with that experience, but checking cellmapper.net suggests the areas I've been should still have some 5g availability on compatible bands. I've checked that it's set to 5g preferred, SIM was in a iPhone 13 Pro and Zenfone 9 previously, both of which were getting 5g in these areas, and I've checked that it's set correctly for preferred network type under *#*#4636*# from the dialer.
APN settings are mostly greyed out from editing, I can pretty much only add a name to one for what's allowed. VZWINTERNET entry looks fine though, and everything else such as mms/sms/calls/LTE data area all fine.
Phone is unrooted and I'm trying to avoid tinkering too much, but can unlock BL if it's absolutely necessary. I've got a US Mobile (Verizon MVNO) sim that also is only showing LTE for data if I pop that in.
Not the end of the world as I often switch over to LTE instead as it's often more reliable for me, but curious if it's still something I can get working.

You should have 5g with N77/78/5 bands, seems strange that the apn stays greyed out, maybe see with your carrier.

Yeah that's what I was expecting for supported bands. Calling the carrier went about as well as I expected, "your Xiaomi device isn't compatible with the Verizon network, especially since it's missing Band 13. Do you have another device you can activate instead?". Looking around on Google, seems like carriers might be able to lock APN settings on a SIM, so that might be what's happening there, but not sure. Thanks for taking a look at it with me.

But B13 concerns 4g, anyway bands N77/78 have a low range and are mainly used in town.
