I have a N-910U, my understanding from here at looking at service mode is that this variant supports Cat6 but in NZ there has been no suggestion this is even close to being rolled out. Tonight I have weirdly started seeing 4G+ (see attached screenshot). Hasn't stayed long enough to do a speedtest. Any idea what this means? Have never seen it before and haven't seen anything talking about it.

You get the 4G+ icon when you get 25MHz or more LTE carrier bandwidth. In most/all cases this is achieved by carrier aggregation and it requires cat6 modem.
Yup cat6
The NZ N910U units do indeed support Cat6 with carrier aggregation, as well as VoLTE.
Where in NZ are you seeing 4G+?
Further googling has suggested vodafone have a cell site in Northcote with carrier aggregation enabled.
If you jump into service mode (*#0011#) you can see exactly which bands it's connected to.

Hi Guys,
I have read lot of comments & QA's, still i have no clarity.Some one please clarify me.
If i buy S7edge Verizon (Sd820) can i use it in india.Verizon bands are 2'4&13. However i heard that verizon lte phomes are unlocked. Can i use in india lte network(Jio or Airtwl LTE network.
However locking is software thing(firmware), can i install international firmware (935U , not sure) to unlock all lte bands, to use any simin world....
Indian lte bands.
TD LTE 2300Mhz
FD LTE 1800Mhz
Please help
This appears to show that if you flash the U firmware, you should be fine (if the information from this website is correct).
https://www.frequencycheck.com/comp...5u-galaxy-s7-edge-td-lte-samsung-hero-2/india
It shows that the 935U is capable of Band 3 (FDD 1800) and Band 40 (TDD 2300) for LTE.

Sorry I am interested in this as well. May I know if you read somewhere that can confirm the unlock of bands by flashing U firmware? I am not sure if the U firmware contains the baseband that would unlock the LTE bands.

Here's an article on XDA. It applies to the G930 but it is the same for the G935.

From what others say, the U firmware runs better since it doesn't have all of the Verizon bloatware. I guess it's up to you whether you want to or not, but I would recommend flashing the U firmware since you don't really lose anything except HD calling and visual voicemail. You'll be able to use your hotspot for free since it won't check to see if you're subscribed, and you will get updates from Samsung rather than from Verizon.

I have the S7 Edge Unlock on Verizon. I can confirm the hotspot works. However it sucks not having Wi-FI calling or Visual Voicemail. I wish there was a way to get both.

There is if you root your phone and flash on a different rom that's based on U's firmware but adds Verizon's extra tweaks and still no bloatware. But then you run into the problem of having horrible performance on your phone, some people don't mind, others flash back to stock. Pick your poison I guess.
I got a galaxy S7 edge SM-G935FD what do I need to do to make it work on verizon?
Verizon is a CDMA network and S7 Edge for Verizon was built only for CDMA networks (https://www.unlockunit.com/blog/cdma-networks/)
You can check your phone's frequencies, but I suggest that before placing any unlocking order, check with your local carriers if they support that phone.
Make sure you have all this info beforehand so you won't have to pay for a useless unlocking.
Various websites confirm its compatible with LTE band 17. My other phone connects to it while in my house, but the Zenfone will mostly connect to HSPA+, or sometimes LTE band 2. I cannot get it to stay connected to LTE unless I get into town or on the highway. (Actually as I'm typing, it switched to LTE band 2, but in awhile it will go back to HSPA)
If I root is there any way to unlock band 17? I'm in the US and my carrier runs off AT&T towers. I got this phone specifically because band 17 reaches far off places much better but I am unable to use it.
Edit: I just realized the model number in the Android settings is "asus_Z012DA" and that apparently is not a US variant. I didn't know about the different variants at all. Am I out of luck?

Hi!
Your correct model for band 17 should be Z012DC, the same used in Brazil.

For the time being yes you are. There is a way to unlock LTE bands on Qualcomm devices, but it seems ASUS has a fail safe built into kernel preventing it at the moment. If there is ever a custom rom developed for your phone then it maybe possible to unlock band 17. Until then no. I have been trying on my Zenfone 3 Ultra. Got as far as entering in the values for the bands I want and when I reboot it resets them to default. You can read up on it here:
https://forum.xda-developers.com/zenfone-3/help/help-putting-phone-usb-diag-mode-t3571627
Me and another user have been working on it. Maybe it might work for your phone. Always a chance.

Yeah I realize that now. Even though I'm stuck with my phone, I still can't find the z012dc for sale anywhere. Practically no seller online lists which variant it is. In fact, after a few hours of research, I never even knew there was specifically variants.

Whoa thanks man. I'll keep checking back and maybe I'll try it myself. Seems you guys are close.
I must say though, this isn't a complete deal breaker, though I am stuck with this phone anyway. The Hspa network is actually FASTER than LTE band 17 in my house. I'm just afraid if I travel somewhere and only band 17 is available I might run into some trouble. But then again, 3g or Hspa might still be able to connect.
Hey everyone,
I read for hours but unfortunately I haven't been able to find the solution.
So I bought a Galaxy S4 GT-I9515 in Europe and I'm not able to get any speeds higher than 2g on my USA 4g T-mobile plan.
The network mode is set on auto connect (LTE/WCDMA/GSM). I tried setting up a t-mobile 4g APN but it won't accept it (it pops back to standard after a few seconds..)
The simcard does work at 4g on another phone.
I rooted it with chainfire autoroot but this made no difference.
Anyone have a clue? At least 3g would be nice and should be possible..
Does the gt-9515 support the carrier's 3g and 4g frequencies?
Hey, thanks for thinking along..
According to frequencycheck.com, yes (both 3g and 4g).
Also, the t-mobile store didn't make notice of this being a problem. They were horribly incompetent though (just googling everything..) But you'd think they would at least check that much.
The I9515 won't get LTE in Europe as bands 2, 4, 12, and 17 aren't used there. The best you can do is HSPA (3.5G in the US) for data. If you're not getting at least HSPA the local carrier may have throttled you.

If I put the simcard in my old phone (moto G 1st gen) it makes an LTE connection so I'm not throttled.
I downloaded an app called LTE Discovery which doesn't read an LTE connection but says HSPA: -75.0 dBm is available.
With an internet speed test I'm only getting 770 Kbps however.
Oh, and I'm in Las Vegas currently (not in the middle of nowhere before anyone asks.. )
It's about the same speed in the Bay-area.
I misread your initial post. The fact you're not picking up LTE in Las Vegas means something else is wrong. In fact it makes me wonder if you even have an I9515. Kindly enter download mode and read off the model number please?
If things are as I suspect they are, then you're actually in possession of an I9505. My comments in my earlier post regarding LTE still apply, except it's the phone lacking the US bands instead of lacking European bands.

You're right, I mentioned the US T-mobile plan but forgot to clearly mention where the problem was occurring/where I want to use the phone (which I bought in the Netherlands). Just to be clear: I am in the USA and that's where I intend to use it.
ODIN MODE
Product Name: GT-I9515
Ok...I'm really confusing myself. For some odd reason I had the Straight Talk S4 in mind. LOL.
The I9505 and I9515 have the same bands: 1, 3, 5, 7, 8, and 20. You won't get LTE in the US on this device and are limited to HSPA here. Fortunately, HSPA is fast enough for multimedia, so unless T-Mobile is repurposing its 3G network for LTE you should see about 4 or 5Mb a second.
Thanks for analyzing, you seem to know a lot about this.
However, the primary problem is I'm not reaching any HSPA speeds either.
I know a lot about this, as I have an I9505 and live in the US.
The phone is working properly, so speed issues are carrier related. And it's not uncommon. I've had it happen myself, on AT&T towers.
Does anyone here have a UK G950F or G955F on T-Mobile in the USA?
I am curious as to the LTE speeds you are getting.
Currently if I take a N950F on T-Mobile and Speed Test it next to a N950U or a N920T also on T-Mobile, I get a fraction of the speeds.
For example right now Im getting 203mbps download on my N950U / N920T & on my N950F I am getting 50mbps.
During the day when there are more users on we could be getting 40mbps down on the N950U / N920T and be getting less then 10mbps on the N950F.
To make matters worse the connection seems not so stable.
Before you ask this not an iscolated issue. There are several people experiencing this issue.
Matter of fact if you go buy a N950F from Clove in the UK right now and use it on T-Mobile USA it will do this.
Also before you ask, Yes the APN settings are correct, yes we have tried a million and one things, yes CSC(s) are in place
I heard through the grape vine that that also happened on the Galaxy S8 line. So I figured I would stop by and ask.
Thanks in advance for any replies and feedback.
Carrier Aggregation/MIMO? The US unlocked models with qualcomm modems are designed to use mutilple US tower connections while exynos arent.
It's all very carrier specific. T-Mobile certified the Qualcomm S8/Note for their Network, not the exynos. Sure it works, but theyre no saying its 100%.
Varying modem version maybe? Or chipset bindings, Location, Towers, Network Congestion etc.
Right now I have a 950F on T-Mobile in San Diego. Last Modem I flashed was the one included with the Netherlands AQI7 update. I've seen 50-60Mbps and as low as 2Mbps while on LTE.
I recently bought an S7 edge unlocked SM-G935F Exynos version. I am currently using it on T-Mobile and have VoLTE and WiFi calling after flashing the TMobile CSC. However, I cannot get the right bands working for Carrier Aggregation. When I go into ServiceMode, the only CA combinations showing are :
7C(A)
7A-7A(A-n)
There's nothing about bands 2, 4, or 12 that T-Mobile uses. I've tried using various ROMs and CSC tools to try to get the correct bands for CA to show up but nothing. Does anyone have any insight on how to get this enabled? I saw something a year old on reddit but the details were a little vague.

Tried what was mentioned in that article. It didn't work. No idea why the CA is also only showing Band 7 when T-Mobile only uses 2,4,12.
What's even more strange... I brought the phone overseas to Taiwan last week, popped in a Chunghwa Telecom SIM, and all CA band combos for LTE bands 3,7,8,28 showed up without any issues and the phone was lightning fast.

Check with another US SIM card and see if the T-Mobile card's behavior or the Taiwanese one is replicated.
Try with a Metro, Cricket or AT&T card.
Also, on which network was this phone previously used? Because I am not sure if I'm right but if it was used with a CDMA network, it might not work with GSM US networks (not sure about it tho).

I know the previous owner on Swappa said that he used the phone with Cricket, but no clue if he checked if CA was working. Also I thought the Exynos varieties didn’t have any support for CDMA.
