So i saw the G4 went down to 299 on Amazon.com and decided to buy it for my parents.
http://www.amazon.com/LG-G4-Unlocked-Leather-Warranty/dp/B01774WPQ8
After purchasing and it was too late to cancel, I noticed a lot of people complaining they were having sporadic issues with the US991 model.
This model was manufactured by LG for US Cellular. They are a CDMA based USA Cellular Provider.
When I Googled the mode, I found a page for this specific model directly on LG's website.
http://www.lg.com/us/cell-phones/lg-US991-Genuine-Leather-Black-g4
Specifications
Type Smart Phone
Form Factor Bar
OS Android™ 5.1 (Lollipop)
Technology GSM, CDMA, WCDMA, LTE*

RAM 3 GB
Network Hepta Band/Dual Mode*
Frequencies LTE Bands 2/4/5/12/13/17/25, CDMA 800, 1900 MHz, WCDMA 850, 900, 1900, 2100 MHz, GSM 850/900/1800/1900 MHz*
From what I can tell, WCDMA is just another name for UMTS which is the basis for HSPA/HSPA+ Which means that this phone should be compatible with jut about any GSM carrier providing H+ 3.5g data services as well as typical Voice and Messaging services. What this should mean overall, is this will work as an unlocked international GSM compatible phone.
Data Transmission EVDO, EVDO Rev.A, 1xRTT, LTE*
Dimensions 5.86" (H) x 3.00" (W) x 0.38" (D)

Touch Screen Yes
Battery Capacity 3,000 mAh
Talk Time Up to 18.5 hours**
Total Internal Memory 32 GB (21.9 GB usable)
microSD™ Memory Slot Supports card up to 2 TB***
Also, based on US Cellular's unlocking policy page for unlocked carrier locked phones,
http://www.uscellular.com/site/legal/mobile-wireless-device-unlocking.html
The US991 G4 comes carrier unlocked from US Cellular so if there are OS updates and such there shouldn't be any cases of carrier relocking (YMMV).
All in all if you are purchasing it just for general cellphone purposes it seems fine. Rooting and ROMing is another issue entirely.
If anyone can add some additional information to this I would be glad.
I hope this helps someone out there.
We're using one on T-Mobile, and everything is working just fine...no issues so far.
buydig had it for $290 on its eBay store (it went up now) with both black and red leather backs.
LTE bands are OK for AT&T (2,4,12,17) and T-Mobile (2,4,12) in the US.
It's missing LTE bands 1,3,7 which are used in Europe.
WCDMA doesn't have the 1700/2100 band that T-Mobile was using but has refarmed to 1900 in most areas now.
My friend bought the same buydig/ebay deal as above, is using it on Verizon. He just popped his sim out of his dead razr m and it works ok, except it being an unregistered device. His is listed as US99110A for software version, Kernel 3.10.40. It won't do a software update with the sim in (obviously) nor without the sim in it. I guess flashing the US Cellular KDZ over would work, but then it includes all their bloat and there's no way to get back to it's current unbranded status. Would be awesome if it could be updated.

Hi, I just received mine, also using on T-Mobile. Works fine, but a couple issues, and possibly a deal breaker:
(1) After upgrading to Marshmallow and signing onto Google to synchonize apps, LG Backup no longer works. Icon still there, but no response when clicked.
(2) Upgrading, from G3, happy to report that Facebook app no longer crashes with Acore error -- not sure if that's because (a) settings changed, (b) upgraded from G3 to G4, or (c) Marshmallow cured it
(3) Cannot find wifi calling, which is necessary for using free text on GoGoInflight-equipped airliners.
I like the $275 price, but #3 may be a deal breaker. If can't make it work within budget, must choose between NEW G4 without wifi-calling, or used G4 with it.
Any thoughts or suggestions appreciated!

I don't think wifi calling is available as-is with US991 on T-Mobile, but you may be able to use an app for it. Check out "Hangouts Dialer - Call Phones" app.
can any of you guys confirm whether 3g on T-mobile works? I can see that 2g and 4g LTE are fine, just not sure about 3g since my provider has 3g crossed out for this phone.
StraightTalk won't activate it on one of their Verizon SIMs even though it will work on Verizon. I sent mine back and bought a used Verizon model.

So, if you are in an area that T-Mobile refarmed their 3G from the 1700/2100 band to the 1900 band, then you should get 3G. My understanding is that they have done so in most if not all areas.
Just to confirm, will the US991 will get 4g on both verizon and gsm carriers? I have to switch my vzw sim back to a micro sim before I can try. I'm also going to switch to an mvno in a couple of months, just want to make sure it'll work.

Of course, as far as the phone supports the LTE band the GSM carrier work with and the phone is set to Global.
It supports LTE Band 2/4/5/12/13/17/25. I'm using it on GSM carriers with LTE band 2 and 4.

Just bought a new G4 on eBay with extra battery, battery charger cradle, and extra leather cover for $289 shipped. Brand new. Box says manufacture month was 03/16. Its working great so far. Its on MM out of the box. Threw an Unlimited T-Mobile SIM in it and its working pretty good. Nice.
Hi. I'm wondering if I can get some help with this device. I purchased this device unlocked from my local Rent a Center in New York. Since its unlocked, I am using with my servicer provider Metropcs. Here's where im having some issues. Metropcs offers WiFi Calling on all their devices [ have a LG K7 ] as does T-mobile since they own metro. I noticed that the feature is MIA on my G4. I did some research and found out from LG that the phone itself was originally a US Cellular device. I then called US Celluar. I spoke with their techs and was informed that they don't offer WiFi calling at all with their service, but it doesnt mean the phone doesnt support it. Believe it or not, the tech told me that its more or less a software thing. I went through the stage to upgrade the device to Marshmallow, but apparently its not available. I noticed that all US Cellular LG G4's have Marshmallow. Im wondering if theres a root method that might fix my issues. I looked around and didnt see one for this LG G4 US99111a. I only see them for US99110. Can anyone here at XDA possibly help? Any and all info will be appreciated. Thanks in advance.

There is not root method yet. Since wifi calling is a metropcs/t-mobile feature you can't get it in a device is not from them, unless someone port a metropcs/t-mobile ROM to other carrier devices.

I kinda figured this was the case, but was hoping. Im wondering though that if and when US Cellular does support WiFi Calling, will an update from LG activate the feature. Either way, its a great phone. No complaints. Just wondering what marshmallow is like on it.
Not sure if the wifi calling feature from one carrier works in any other carrier.
Sent from my LGUS991 using XDA-Developers mobile app
It does with other phones I have had. I owned an Iphone 6 Plus from Verizon. The phone is factory unlocked, and I used it on Tmobile/ATT/Sprint before moving to metro. Verizon initially didnt offer Wifi calling. The feature was active in the phone once I left verizon for the others. So its possible. Hence my confusion as to why its not active with the G4, and why I believe the tech at US Cellular told me that its more or less a software issue.
Iphone is kind of different. But I hope it works with Android

The closest Ive thus far researched is the mediapad with LTE that can make and receive phones. Issue us none of the LTE bands work on T mobile USA.
Was wondering if anyone would know of a tablet that can accomodate a SIM card and work on T Mobile usa LTE network as well? Most the ones I see are data only.
Thanks.
I would have thought the US version of the Mediapad m3 would support T-Mobile LTE?
Anyway, have a look at the Galaxy Tab S2 LTE. It should...
Edit: nevermind, you asked about Voice. S2 LTE doesn't do voice other than VoIP.
A little outdated, but the Sony z3 compact tablet does voice calls and should be T-Mobile compatible.
How about the z4 ? US version. Xperia Z4 Tablet Sgp771us/B 1303-5541
Sent from my SGP771 using Tapatalk
does the mediapad m3 support rogers/fido? I'm on the same boat I have the killer $15/3GB tablet plan from fido looking for a tablet to put the sim in
I bought the Z4 LTE tablet and it works. The version is hk Chinese international model that has voice enabled. I don't think the USA spec has the dialer. All works except for volte. Since it's not t mobile provisioned bull****.
To see if phone or tablet works with carrier
You need to go to this site. WillMyPhoneWork.net Anyone else find one that has spec's like this that will work with T-mobile. That's what I thought I bought. When I purchased mine Amazon had it in the spec's as haven't voice phone...
With T-Mo the best you'll get is H+. I have been using this tablet with AT&T and all I get is H+ in Chicagoland but it is acceptable although I have issues from time to time where I have to reboot to make a call. The issue is that this tablet does not physically have the LTE bands that the US uses for LTE. Sucks because otherwise this is a great tablet/phone. Of course I have the international model BTV-DL09
I am thinking to buy one, but I was previously burnt on Nextbit Robin being not able to get data service in Canada. Robin could see voice and SMS, and latched on local Canadian carriers fine (Bell, and another one I forgot its name), just no data. Rumor says the manufacturer did not certify this device with any carriers outside of USA.
I want to make sure that this Pro3 can get data in Canada. I am on T-Mobile.
FYI, regular OEM devices such as V20, S3, S4, S7, Moto G4 Play all worked fine in Canada.
I'd appreciate if anyone can share their experience with this phone in Canada. Thanks,
T-mobile is a US carrier not Canadaian, but nonetheless Le pro 3 will work as it has AWS.
I know for a fact cause I'm on Freedommobile that also uses AWS for 3g data and it works fine, LTE is another matter.
I think all Pro 3 HK variants only have 1700/2100 LTE, not 3G. Should work with all carriers in Canada AFAIK, though I'm not sure about Freedom.
So I am looking to buy an international (or Latin) version of either the S10+ or the Note 10+.
I am on T-Mobile in the U.S.
1. How "bad" will it be if the phone has 3 out of T-Mobile's main bands? It only lacks 71, so what's the impact will be if I don't have band 71 on this phone with T-Mobile?
2. I read in the forum about flashing T-Mobile firmware on unlocked phones. How necessary is it? I prefer not to mess with flashing anything; done it in the past, I am not 'afraid' of it, but I just don't feel like going that route. Will I be missing anything from the T-Mobile network and services if I keep the phone in its stock ROM?
For example: Wifi Calling (important to me), VoLTE, etc. Will I have access to these features if I don't flash the carrier's firmware?
Thank you.
Band 71 is used only in rural areas where cell towers are very far apart . My phones have never used band 71. If you don't know what bands your phone typically is using you can download a free signal app from the Play Store that will show what band your phone is connected to. Unless you live in a very rural area or frequently find yourself in rural areas it's unlikely you need band 71.
Flashing T-Mobile firmware shouldn't be necessary. I don't have the international S10+ but rather the US unlocked model and I get both WiFi Calling and Volte fine without T-Mobile firmware.
I've used many different models of international unlocked phones from Xiaomi and Huawei on T-Mobile and always got both WiFi Calling and Volte to work with only one exception--the Mate 20 Pro. I had to get rid of that phone even though I really liked it because calls kept going to voicemail without the phone ever ringing first.
It turns out that on T-Mobile if your phone supports band 12 it also needs to support Volte or calls go straight to voicemail without ringing if the caller is using Volte . I never had that problem previously because in 5 years of using international unlocked phones the M20P was the first where Volte didn't work on T-Mobile.
There were lots of posts from T-Mobile customers in the XDA M20P threads about calls going straight to voicemail. I haven't read a single post about that issue with the S10+ so it's pretty safe to assume that the international S10+ works fine with Volte on T-Mobile.
Until the S8 Samsung didn't even sell a US unlocked model--everyone in the US with unlocked Samsung phones were using the international models with the Exynos chip and those phones always worked perfectly with T-Mobile which is very BYOP friendly (unlike AT&T).
The only thing you would be missing on the vanilla Samsung firmware is Visual Voicemail but last I checked you could just download the official T-Mobile Visual Voicemail app from the Play Store.
You would also receive your OTA updates from Samsung rather than T-Mobile but that's actually a plus because the unlocked Exynos models receive updates much more quickly than all of the US models including the unlocked Snapdragon models.
Sorry for the very long answer but I wanted to be thorough.
You should be fine with an international unlocked S10+ on T-Mobile. This is a much better phone than unlocked models from Google Pixel and One Plus so I would recommend going for it.
No manual flashing on your part will be necessary.
@jhs39 - Thank you for your extensive response. It is greatly appreciated!
OK, so I mostly use Band 4 with my current phone, which is one of TMB's main bands, so it seems like that indeed the lack of 71 won't be an issue.
However, how do I know if the Int. version will support VoLTE on the TMB network? I can't see anywhere any information about this phone even supports VoLTE (other than the carrier's model of course).
What about Video Calling?
Thanks again.

If the international model didn't support Volte on T-Mobile there would be posts on XDA complaining about calls going straight to voicemail without the phone ringing. There were multiple threads about that issue in the M20P section but I haven't seen a single complaint about that happening with the S10+.
This phone has been out since early Spring so if there was a problem using the international model with T-Mobile somebody would have reported it by now.
I don’t know anything about video calling though because I use T-Mobile's network via an MVNO and my carrier doesn't offer video calling.

That's odd. I'm using a mate 20X and the although it lacks bands 66 and 71 I don't get calls going to voicemail. In fact when viewing my historical phone signal via gsam app, it shows that I always receive a better signal than even the S10+ that I'm currently using. Both devices on T-Mobile USA.

Thanks @varcor . What about Video calling?
BTW - is it 975F or something else?
I use Skype for Video Calling, it works fine. Mine is an SM-G9750, the best price I've seen is on Ebay. The only issue is when you first get the device you'll need to change the language since it's setup in Mandarin. A bit challenging but not a big deal. The Ebay vendor is in Houston which is where the device ships from, only takes a few days.

I must the F model. I travel to Israel with a local SIM and they use the F model, and it's the only possibility I have to use their WiFi calling while there. I am not 100% sure it'll work because of firmware but better chances with F model.

Not having bands 66 & 71 don't cause the problem with T-Mobile calls going straight to voicemail--if band 12 is supported on a phone T-Mobile assumes the phone also supports Volte and if it doesn't then you get calls going straight to voicemail.
I'm not familiar with the Mate 20X but before the M20P I had a P20 Pro, Mate 10 Pro and P10 Pro and none of those phones had an issue because T-Mobile Volte worked with all of them.
It's also possible the problem with the P20 Pro was fixed after I got rid of the phone since it was a firmware issue that was fixable in a software update . I kept mine for 6 months before throwing in the towel. The only workaround was to turn off 4G in the network settings. With 4G off you would receive all calls since Volte is a 4G function.
I personally love Huawei phones. Hopefully after Trump is gone all of the nonsense with Huawei being barred from using Google apps and bullied out of the US market will go away but they might decide selling their products here isn't worth the aggravation.
I've also used a bunch of unlocked Xiaomi phones on T-Mobile with no issues. A nice feature in MIUI is that if Volte doesn't work out of the box there's a dial code you can enter to manually enable it.
Band 66 is an offload for band 4 when band 4 traffic is high but if a phone doesn't have band 66 it just stays on 4 so not having 66 on an unlocked phone has never caused any problems for me.
Band 71 is only live in parts of the country and is relatively new. It can transmit a signal over unusually long distances and is used to provide cell coverage in rural areas where it would cost too much to build a full network of cell towers.

P20 pro was certified and worked fully on T-Mobile , most devices after that were not.
I don't think my mate 20x connected to band 12, but if it did, then yes it'll probably go straight to voicemail.

The SM-G975F is the Exynos SoC variant for Europe. The SM-G9750 has the Snapdragon SoC and dual SIM's as well. Wifi Calling will work on both devices in any region, including Israel as long as the service provider offers it. The only thing I would recommend is you do some research on Exynos vs Snapdragon SoC's in the S10. Good luck!

I am aware of the differences between the two chips.
In regards to WiFi Calling - I am a bit skeptical. This provider does have WiFi calling services, however they have a list of devices that are supported. Clearly they list devices and firmwares that they sell, not BYOD phones, and they sell the F version. I currently use ZTE Axon 7, I have WiFi calling on T-Mobile but it does not work on the Israeli network and when I try to 'register' it for this service through their app, it clearly says that the device is not supported.
That being said - I can't tell you if my phone doesn't work on their WF calling because it's not even sold in Israel. It could very well be that any version of Galaxy S10+ will be supported regardless of firmware. simply because it is sold there. Clearly there is no way to know this beforehand. I asked them, they of course can only guarantee phones that are sold by them and are on the list.
BTW - the Israeli version of the 975F is single SIM, they don't have the D/S, although I can't imagine this should have any impact of phone supporting or not supporting WF calling.
What's the difference between the F and the O, other than the region they are sold in?
Thanks.

P20 pro was certified and worked fully on T-Mobile , most devices after that were not.
I don't think my mate 20x connected to band 12, but if it did, then yes it'll probably go straight to voicemail.

Devices don't need to be certified by T-Mobile to work with Volte. All of my recent Xiaomi phones worked with Volte--none of the models were officially sold in the US or certified by T-Mobile. The P20 Pro was not sold in the US so there was zero reason for it to be certified by T-Mobile. The last Huawei phone officially sold here was the Mate 10 Pro. AT&T and Verizon require that devices be certified by them to work with Volte on their networks but T-Mobile does not. T-Mobile is very BYOP friendly.

Thanks for the clarification. So why is it then that same device , but using different sim card would show the Volte toggle or hide it from the user menu? Example, mate 20 does have Volte capabilities yet its missing the Volte toggle switch. I know on the Xioami devices one can enter a #*code to force it show that option. I think what makes it even more convulsing is that Huawei global versions have various region firmware via their Cust codes. Each one I noticed behaves slighly different using same T-Mobile SIM card. Cheers
You mentioned all calls went to VM on up 20pro, why do you think that was the case, you mentioned earlier that you thought possibly it may have been firmware related amongst other things.

You're correct regarding Single SIM for the SM-G975F, the Dual SIM option is available in the SM-G975F/DS. I personally wouldn't consider obtaining a device in Israel if the majority of the time I'm the US. The major differences are SoC's, a minor difference in CPU Clock Speed and Cores. The SM-G975F has no FM Radio and offers fewer Primary Network capabilities. You can view a back-to-back comparison here.

This is quite different than your original question but with that being stated I would be confident enough in the SM-G9750's compatibility with the Israeli network for Wifi Calling. The worst case is not having Wifi Calling in Israel, which isn't an absolute necessity however you'll have the Snapdragon SoC which is a far better chipset with fewer bugs. For me it's the obvious choice if I were faced with your considerations.
You're most welcome

SoC, meaning the chip?
You see, your definition of "worst case not having Wifi calling" is important to me , simply because where I usually stay in Israel there is almost no reception at all (inside the house I am staying in), that's the main reason I want a device that will be able to use their Wifi calling.
Also, I looked at the eBay seller that you mention and I don't even think he carries the O model any more, all I see is the F model, unless of course I am missing something.
Thanks.

SoC is System on Chip, same as Chipset. If Wifi calling is a top priority buy the Exynos device to be certain but be advised there are numerous concerns over the chipset on XDA and other sites, plus Network Aggrigaton for Exynos in the US has issues with some T-Mobile clients. You may lose Wifi Calling or VoLTE in the US.

They still offer the SM-G9750, the link I shared is correct, not sure you missed something. The also sell the SM-G975F and SM-G975F/DS.
I've been following the phasing out of 3G and don't mind adjusting to change even if it renders my G4 Plus obsolete. My main question is whether or not G4/G4 Plus models are obsolete in reality. After all, it's a 4G phone that supports VoLTE and wi-fi calling.
AT&T Prepaid is telling me the phone is "3G dependent" and they're trying to muscle me into a newer phone. BS sales pitches from wireless carriers I get. But extra pressure in the form of a two-day notice is especially dubious.
Here's the interesting part of AT&T's notice sent yesterday:
"ALERT! It's time to replace your 3G dependent phone! ...If you don't replace your phone, by July 25, 2021, any calls you make will be redirected to customer service so we can help you upgrade to a newer phone. Some features like voicemail won't work when calls are redirected. To avoid service disruption please call (877) 475-2662 to get your new FREE phone today or stop by your AT&T store for other options."
First, my G4 Plus isn't from AT&T and is carrier unlocked. Second, what do they mean by "3G dependent" for a 4G phone? This would make sense if 4G traffic traditionally passed through 3G relays. But AT&T pretty much owns the market in my city and 4G signals aren't hard to find. What adds to my confusion is that whenever I read about the end of 3G the usual takeaway is that 4G devices 'should be ok' and not to worry.
Officially, 3G ends in February 2022 but I never intended to wait that long even if our athene models won't work as usual. I was hoping to make it to the end of summer or December at the latest. It seems the carriers are ratcheting up their unofficial dates.
For now I'm planning a stopgap that involves a different carrier. I'd appreciate hearing how other athene users are adjusting.
The situation is better for me. I have 2 sims, Airtel and Jio and haven't used 3G network since more than 2 years.
Jio offers 4G only network since its launch in September, 2016 and athene supports Jio 4G VoLTE officially. So, no problem with that.
Airtel discontinued its 3G service in many parts of the Country more than ~1.5 years ago, including where I live. But, athene unofficially supports Airtel 4G VoLTE on AOSiP Pie (at least for me, other Pie ROMs require Airtel VoLTE hack found in Themes, Apps and Mods sections). So, no problem with that either.
My primary device is Asus Max Pro M1 and will complete almost 3 years soon, but if something happens to the device then I won't be stranded and I can use athene as my fallback device because both carriers support 4G VoLTE.
From what I've figured out so far, the reason AT&T says their SIM will stop working come February 2022 is because they plan to blacklist older phones regardless of 4G capability. i.e., Just another extortion tactic US carriers are known for. Can't say for sure about other carriers, although I can't imagine Verizon not playing the same joker card.
