I am on H2o, an AT&T MVNO. (I have inactive T-mobile sim card. I assume that won't work. I may be able to borrow an active t-mobile sim... ) I don't understand why such hidden code is sim dependent.. I also have trouble getting into the service manual (using back and key Q+0000) after I get into service mode *#2683662# I would at least see what LTE bands are already enabled if I were able to see the service manual.
[Sprint Samsung Galaxy S7 Guides, News, & Discussio] micallan_17:
The Inactive sim works, the sim cards i used were all inactive. I have no idea why samsung made it sim dependent. try using the inactive t-mobile sim and try these codes: *#0808#, *#73#.
[Sprint Samsung Galaxy S7 Guides, News, & Discussio] yutaka001:
Tried an old T sim card, but the phone won't reboot in step 2, showing "please wait" for more than 5 minutes. I also tried a relatively new Verizon sim and it was doing the same in step 2. I guess the phone was trying to configure the sim or something but stuck... Granted, both sims were cut into the exact nano size. That may have caused the "error" but the phone did detect the change of carrier/sim by prompting "service provider update". Well, I guess I will try to borrow a sim card and try again when I get some time. Thank you and will keep you updated in a few days.

Hello,

Is there a way to do this without a US sim card because I would like to unlock the 28 band, which is important in France.
[Sprint Samsung Galaxy S7 Guides, News, & Discussio] stormeking:
I made an XDA account just to login and say THANKS! I have a Galaxy S7 G930V that I flashed to G930U firmware via ODIN because I sold my S8 (waiting on Note 8 in the mail) and wanted to use this in my rural town. Without band 17, I was getting spotty signal on LTE but still great signal on HSDPA+. Since I own a prepaid cellular store, I had this phone lying around that I just received back from Samsung (they replaced EVERYTHING on this device for free because the battery was expanded and didn't charge me anything - guess they were worried about bad press since the Note 7 issues that happened) and I wanted to use it for the time being. Your method, followed to the letter, worked flawlessly on this SM-G930V (Verizon) flashed to SM-G930U (Unlocked) firmware. Thanks a million!

Note - I forgot to mention in my original post that I used an AT&T Prepaid sim card. Also, I had to redact all links due to XDAs understandable policy preventing new junior members from posting external links - this is why the quoted message is missing the URL links. Thank you again for all your help!
[Sprint Samsung Galaxy S7 Guides, News, & Discussio] micallan_17:
The only way I think you can do it without a us sim card is by rooting the phone then using an app as this one below to launch the hidden menu settings needed

[Sprint Samsung Galaxy S7 Guides, News, & Discussio] tisazalay:
I tried all the steps, I used an ATT Prepaid SIM (while traveling to the US, it had LTE), and opened Band 28 which stayed slected troughout boots. Back in Panama, I repeated the steps using the ATT SIM and my Movistar SIM, and band 28 stayed selected, but phone only shows H+ (it showed LTE in the us), I wonder why my phone doesn't connect to LTE even though band 28 is open and that's the band that's used here. When I bought my phone it already had SM-G935U firmware although it says Verizon in the back. The Movistar SIM is the same I used with my S6 Edge and the S6 did show LTE. Any clues as what is going on?

Samsung Galaxy Tab S 10.5 SPRINT CDMA (SM-T807P)

I'm ouside US and without US sim cards and without chances of getting one at all.

My local carriers are all WCDMA (LTE/HSDPA/GSM).

I have flashed stock firmware, then root, then unlocking and debranding.

I can access all options but it seems the WCDMA bands are locked or not supported (trying to connect all the time to the carriers with all SIM CARDS with the appropiate APNs.)

I will give this guide a chance to enable the necessary service / bands and I will let you know.

I hope to be able to thank you soon.

No working on my rooted, unlocked & debranded Samsung Galaxy Tab S SM-T807P SPRINT CDMA.

All OK but the setting (additional LTE bands) is not saved after reboot.
[Sprint Samsung Galaxy S7 Guides, News, & Discussio] SoNic67:
The bands not staying selected it's due to the phone firmware. It happened to me with an Asus Zenfone and the solution was to replace one of the system files with another from a similar phone. In the case of Sprint S7, maybe just flash the "U" firmware on it?

I did flash the "U" in my "V" phone and the LTE bands are staying selected. Now... I don't know if they will really work too. On a Moto phone, the band 20 that I selected in US din't work in EU, probably because of the lack of hardwdare (Radio amplifiers?). When adding just the band 12 when the phone has already 13, the frequencies are really close (700MHz A-C versus C-only), so probably that will work for sure. But if the added frequency is really "far"... don't know.

I have added all the bands that an AT&T phone has to my Verizon one, I will try to make some tests.

BTW when I do *#0011* The fields in that window are gray with gray text, so I cannot see anything. Any ideas?
[Sprint Samsung Galaxy S7 Guides, News, & Discussio] adroideuy:
Finally I could get the additional bands by doing it with Qualcomm Tools.

Should be you get *#0011* menu (ServiceMode) in gray because it is locked by the MSL?
[Sprint Samsung Galaxy S7 Guides, News, & Discussio] SoNic67:
I doubt, it was a fresh (never used) Verizon phone.

LE: I have checked and it's 000000
[Sprint Samsung Galaxy S7 Guides, News, & Discussio] adroideuy:
I could bet that you have the GFC settings locked/disabled (by Verizon) in your modem.

Surely you need root and flash the correct modem firmware with the GFC enabled...
[Sprint Samsung Galaxy S7 Guides, News, & Discussio] SoNic67:
It suddenly became visible. It got scared that I'll root it ?

V useful thread. I have Sprint Galaxy S7 (SM-G930P) and according to the Samsung it does not have LTE Band 40 so I went ahead to activate it. However, when I tried the method described in this thread I noticed the Band 40 already is activated. I have U rom installed (G930UUES4BRC1). Does anyone know how to check if which bands are really functional.

[Sprint Samsung Galaxy S7 Guides, News, & Discussio] micallan_17:

Hi, would this also work for Galaxy A6+?
[Sprint Samsung Galaxy S7 Guides, News, & Discussio] micallan_17:
As it seems the A6+ has a Qualcomm chipset, it may work, i have never tried on another device other than a galaxy S7 so your mileage may vary. Try it and see if it allows you to edit the bands.

I was able to unlock additional LTE bands Galaxy A6+ (SM-A605FZKHXSG) that I bought from UAE.

Previous bands are: 1/3/5/7/8/20/38/40

Added bands are: 2/4/12/13/17/28/41/66

I assume my A6+ has a same hardware as A605GZBHINS (A6+ from Samsung India).

Is my assumption correct?

Out of curiosity, is the LTE antenna for band 12/17 the same with band 28?

Both operate at 700 MHz, so by enabling band 12/17 via Qualcomm tool on band 28-only (APAC region) phone, I'll be able to use it mostly in US/Canada -> is this correct?
[Sprint Samsung Galaxy S7 Guides, News, & Discussio] micallan_17:
I would not be sure to be honest, but i assume if you test it, it may work? i have no use for all those bands so i would not know :)

yup, since you have the U firmware and on Tmobile, you do not need to do anything additional since LTE band support on tmobile is out of the box.

I read the LTE bands with the DFS tools and it shows that bands 1/3/7/20/38 are already enabled.

Worked on S7 Edge

I have a Verizon sim unlocked S7 Edge SM-G935V. I left it stock, no root, and updated the firmware to SM-G935U, XAA version. I then used this method to get all but one of the bands I wanted, 2, 4, 5, 12, 13, 17, 19, 25, 26, 29, 30 and 41. The only band I wasn't able to get was band 14 which is an AT&T band. I didn't deselect any bands so I have the other bands that were already selected as well. This method worked flawlessly. Thanks!

[Sprint Samsung Galaxy S7 Guides, News, & Discussio] billa:
You can only enable bands which are supported by the hardware but hidden via software (NV items). Band 14 is a new ATT FirstNet band, and most likely not supported by the hardware of the S7 series which was made in 2016. Same goes for other bands such as 66 and 71, they came out much later.

Could you share the cdma tool again as the link is dead?
[Sprint Samsung Galaxy S7 Guides, News, & Discussio] billa:
There's a better and easier way to enable all bands supported by the hardware on any carrier without messing with NV tools. Flash it with the latest "U" XAA carrier unlocked firmware from SamFW.

S7 SM-G930U

https://samfw.com/firmware/SM-G930U/XAA

S7Edge SM-G935U

https://samfw.com/firmware/SM-G935U/XAA

Click on the latest firmware link at the top of the "Version" column, then click on "Download SamFW 2 Server".

Download and install the SamFW Tool.

https://samfw.com/blog/samfw-frp-tool-1-0-remove-samsung-frp-one-click

In the CSC menu, enable XAA and disable auto-CSC selection so when you insert any carrier SIM, it will stay on XAA. This will enable ALL band which are supported by the S7's hardware, you cannot enable other band which are not supported. You can see and select bands manually by dialing *#2263# which works with some sim cards depending on the carrier (all bands will be enabled by default).

[Samsung Galaxy S7 Active Accessories] gqukyo:
jlczl already has a youtube review up but here's my take on it. With no pictures. Lol

There is no getting around the size and weight of the case but make no mistake, this phone should last you at least 2-3 days of HEAVY usage. This is not a case for most to carry in their pants/jeans pockets. I'm usually carrying two phones with me in the same pocket (one from work, one personal) and even then, it's still thinner than this case with the phone on it. It also weighs less. While some people like my brother actually carries and uses ZeroLemon battery cases on a daily basis, most of us would only use it for specific scenarios, probably mostly during travel. Some would say, "well you can do the same with a battery pack". Of course you can but it's definitely not as convenient and you'll have to contend with a wire between the phone and battery. Speaking of battery packs, this case has a USB output so you can actually use it as a battery pack to charge other devices.

A few things that I don't like about the case is that when you're charging devices, the LED lights are lit up the entire time it's charging which, depending on the situation can be distracting. Not sure if it's just the one I have but that's my main gripe about this case. The specs list QC 2.0 for charging the S7A but I didn't notice it charging any faster than usual. Regardless of that, it would've been nice if the USB output for other devices was at QC 2.0 as well. Last but not least and should go without saying, you lose the waterproofing for the phone. Well, technically the phone is still waterproof but the case obviously is not. You still wouldn't want water to get between any charging devices whether they're waterproof or not.

All in all, ZeroLemon battery cases may not appeal to most but they definitely serve a niche group of consumers like my brother. Lol

One final thing that will probably please original Gameboy fans. The heft and size of it reminds me of the original Gameboy. It's almost as if I'm using a modern version of the Gameboy. If you've never played hours upon hours of the original Gameboy, you won't know I'm saying but if you did then you'll instantly be reminded of it. Lol

Another thing is I haven't seen a holster for this version. My bro's S4 or S5 (forgot which Galaxy he has) battery case came with a holster.
[Samsung Galaxy S7 Active Accessories] sonhy:
no pics! :p all good mate, nice review.

how much was the case?

would be good if you could test capacity more accurately, maybe turn on airplane mode, then turn on wifi and have youtube play continuous hd documentaries (auto play enabled) with screen brightness 100% and see how many hours it last?... no pressure, just curious :)
[Samsung Galaxy S7 Active Accessories] gqukyo:
No time for that but it's fine to charge almost 2x from a dead battery. The efficiency rating isn't the best but it's not advertised as such either. I'd say,

anecdotally, it's about 70-75% efficiency which is about average.
[Nexus 6P Q&A, Help & Troubleshooting] terrorist96:
People who have the grandfathered unlimited data plan and have an unlocked Nexus 6p can bypass Verizon's tethering restriction (ie tether without paying extra).

My question is for anyone who has an unlocked phone like the 6p and has the new Verizon Unlimited plan: can Verizon detect the 10GB of tethering then throw you to 3G? Or is it not detectable because there's no Verizon software on your phone?

In other words: is the 10GB tether limit detected locally on your phone or on Verizon's end?
[Nexus 6P Q&A, Help & Troubleshooting] nbaj2k:
I was actually wondering this exact same thing, if anyone happens to know.
[Nexus 6P Q&A, Help & Troubleshooting] eregev:

[Nexus 6P Q&A, Help & Troubleshooting] quadcrap1:
How are you bypassing the hotspot detection? Are you using a simple Entitlement bypass the using the standard hotspot that is part of Android, or something different?

Are you sure Verizon is not detecting it? Because there are ways--other than using Verizon apps for the hotspot--for Verizon to detect that your phone is being used as a hotspot.

[Nexus 6P Q&A, Help & Troubleshooting] GatorsUF:
I was also just browsing the Pixel Q&A and it seems some of them are having trouble getting tethering on VZW with the Pixel. I'm on a "grandfathered" unlimited VZW plan and tethering works no problem for me, no hack or tricks need, just use the built in hotspot.

I wonder if some of the Pixel users having problems got their phones from Verizon, thinking maybe the phones that came direct from Google don't have the VZW software that tracks tethering.
[Nexus 6P Q&A, Help & Troubleshooting] tech_head:
It's probably phones from Verizon.

I tether with my 6P on 7.1.2 and have since I got it new with 6.x.

Verizon doesn't do what AT&T and other to do to detect tethering.

I have tethered all my phones for years without Verizon noticing..
[Nexus 6P Q&A, Help & Troubleshooting] imitebewrong:
Seems like they can detect it now. As of two days ago I received a text alert from verizon saying I've been throttled to 60/kbps for going over 15GB this month. I can confirm it has indeed been throttled, even while using a vpn in any configuration. (I've been on the "new" unlimited plan since it was re-introduced and never had an issue with tethering until now)
