The Nvidia FAQ no longer lists the international version which supports LTE band 1 and phone calls. It still says there are three LTE versions of the Shield tablet but lists only 2. This may mean that Nvidia has eliminated the model. Unfortunately, that is the version I am interested in buying. I need support for band 1 and I want to be able to make phone calls.
Does anyone have any info on this?

WHAT CELLULAR NETWORKS DOES THE SHIELD TABLET LTE SUPPORT?
There are three versions of SHIELD tablet LTE. There is a North American version that works on AT&T, T-Mobile and Rogers on LTE bands 2, 4, 5, 7, and 17 and HSPA bands 1, 2, 4, 5.
There is a second International version that works on popular European and Asian networks. It supports LTE bands 3, 7, 20 and HSPA+ bands 1, 2, 5, 8.
Check with your favorite carrier to verify coverage in your area.

PS If they actually produce the third LTE version, I would like to purchase it in the USA.
PPS The description below no longer appears in the FAQ.
The third version also works on popular International carriers, in addition to including voice support on compatible networks. It supports LTE bands 1, 3, 7, 20 and HSPA+ bands 1, 2, 5, 8.

Well spotted.
The UK site confirms all three but perhaps that is just slow to update
http://shield.nvidia.co.uk/tablet-faq/
Could you work around this by flashing the radio from the recovery image of the LTE variant that suited you? Or is it a bit more complex than that?
The UK FAQs page has been updated. The statement "There are three versions of SHIELD tablet LTE" remains but only two versions are listed.
Typical Nvidia debacle. At least edit the statement to read 'two versions'.
is there a way to enable the Band 1? im here at the Philippines and im only getting 3G connection whilst using my Phone with same Simcard i can get LTE signals
You can still text and phone from shield; as long as you're connected..
I know this might not be the info youre looking for specifically, but...
I believe it can help some people, like it helped me
I couldnt sleep without having a chance of a phone options on this tablet until i found the solution the day 3 since owning the Shield. There is an app for this purpose on playstore, and its totally free. To some extent, still worth the try.
Look for editor choice app, after typing in "textplus" you should have it burning into your eyes upon confirming that search. textPlus Free Text + Calls
Now, i havent tried phone calls yet, you get free 5 minutes and the rest can be added free by watching 15 second videos, completing surveys, sharing on social sites etc. (Videos work decent easy , if you got time and patience you could get 100 minutes a day, if not more than that )
You register an account with them, email, simple, pick your area phone and get a number from them. Text works like a charm. Although i did not try to install any other sms app on it, only using the very app itself for messaging and it does serve its purpose well.
I hope i helped to some of you guys. No rooting, common sense simple, free. Exactly what i was looking for.
Hello Zenfone 3 subworld, I'm a Zenfone 2 user. I just bought a 3 MAX and I'm wondering which version I'm getting.
It reads in the back of the box ZT520TL-MT67-2G-16GN-SL // SILVER, LTE, D
Do you have any clue which variant I bought? If I open it and it doesnt work on 4G (Argentina bands 4 and 28) I'm stuck with a 3g phone. In websites like gsm arena, it shows two options, one with the bands that I need and one without them. It was bought in USA.
If you guys have any clue please let me know. Its kinda hard to buy phones sometimes when there are some many variants of a same device.
Thanks for your time.
There should be another identifier in the format "ASUS_Z012DC" or something similar on the back of the box, likely on the top of the sticker on the back of the box in brackets. This is the identifier of the actual model you got. What does it say?
It should be like this
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.
Hi,
I'm trying to figure out if there's any way to see what carrier aggregation bands are compatible with the Galaxy S8 in particular the Unlocked US Snapdragon device.
In Latin America carriers are starting to use CA for bands 4 (AWS) and 28 (700MHz) and based on the research I've done, it's supported since LTE Release 13, yet I want to be sure before I purchase it and get stuck with no CA during my travels. I know some devices allows an engineer screen to show what CA's are allowed, yet I can't figure out the code for the S8.
Thanks for your help!

I believe that's based on your carrier as to which bands they provide for CA. But while in an area with multiple bands, start a speed test or a download of a larger file and enter the dial pad code *#0011# and it will bring up the menu. A little over halfway down it will say "CA - NOT CONFIG 0 0" when you aren't utilizing CA. When you are utilizing it(during a download, speed test, etc) it will show "CA ADD ###"
I've attached 2 Screenshots of each scenario
Thanks for your answer. The issue is I want to know before traveling if this phone will support CA on that configuration. I know the phone supports both bands 4 and 28 based on the specifications on Samsung website, yet it won't show the allowed CA configurations. This depend on both firmware as well as 3GPP release.
I know on the LG G6 there is a code to check this, yet, I have yet to find a comparable code for the Galaxy S8.
Is there any way to confirm this? It should be supported as 3GPP Release 13 includes it and the S8 is a Release 16, but I can't find any confirmation the firmware supports this.
Thanks again for your help!

Found this website, which shows all possible CA configurations, their 3gpp release, how much bandwidth they can utilize, and pretty much everything under the sun that you could want.
http://niviuk.free.fr/lte_ca_band.php
I'm still partially confused now after reading up on Qualcomm's site because I they contradict themselves in this part
"Not only that, but it also supports 4x4 MIMO on two aggregated LTE carriers.
The result is that the Snapdragon X16 LTE can receive 10 spatial streams of data simultaneously, divided across three LTE carriers."
So is it capable of 3xCA or 2xCA.... I'm pretty sure the s8 can utilize 3... But they worded that oddly
Correct. That's the website I saw that states a Release 13 needed for CA between bands 4 and 28.
The only issue is that at firmware level this also needs to be implemented, they can easily avoid enabling this combination for whatever (logical or not) reason. That's why I wonder if there's any way to check this. Worst part is that I can't test this in the USA since we do not have band 28.
can you try code *#27663368378#?
note this process is for the S7 SM-G930U (unlocked model) and maybe it works for you
see attached screenshots
**EDIT**
screenshot number 6 choose number 8 LTE BAND & CA COMBINATION
maybe numbers may be different for yours too
I am also trying CA here in Asia using a local SIM with my g955u. It is not working. The frequencies are supported. But it seems the firmware is not allowing it at all. Again some carrier limits imposed on customers. I am using g955u unlocked but it is on tmobile. I put a local SIM here in the Philippines. No CA. TMobile is crippling the phone. I plan to change the firmware to the unbranded one.
Also the service mode.
Only *#0011# and *#2263# works
The UE Setting I am still digging which code will open it. BUT I think TMobile disabled the code also
You can check the carrier's network here https://www.frequencycheck.com/
And then you must verify your phone's bands to see if they are compatible.
It is safe to say Carrier Aggregation or LTE-Advance is crippled and is only for use in your original mobile service provider network... outside your telco network and roaming around the world you will not get LTE-A even if the LTE bands are listed in the specs... Waste of Qualcomm modem... I think Apple still has the best implementation of lte modem... the carriers can not dictate on apple... Samsung is more than willing to please carriers... big difference...
We Surely got a crippled LTE phone when outside the original network... unless you root the phone...

lol Apple buys their modems from Qualcomm
Yup Apple buys from Qualcomm but their LTE-A works in any carrier. That is why they have only 3 iPhone models a year. Not including the Chinese variant which have a different lte standard.
I'm also trying to find out which CA combination works for my G950U1. I tried a secret menu and I have there 3 items:
- 2DL CA Combination (under this item is nothing)
- 3DL CA Combination (under this item is nothing)
- 4DL CA Combination - there is 2A-4A-7A-12A which means this:
But I'm using this phone in Europe and I have a problem with CA. I'm sure this phone has no problem in the USA. I did my little research (work for the operator so I ask a colleague for track) find out which UE Capabilities are supported in the operator network.
First of all here are supported bands which is okay for me because we have B1, B3, B7, and B20:
The next important thing is CA combinations. Here is my problem. In my country, we have 2CA to 4CA. On the place where I work is 2CA. And that's the first thing I noticed at G950U1. The mobile couldn't do the CA and I found the reason. In the first picture, you can see the phone supports 6 combinations, but every combination has only 1 band. And that's strange.
Based on this Wireshark log, my phone in my country and in my mobile network doesn't support CA. The question is - what will happen if I manually change / edit CA combination through QxDM program.

Hey guys I've had my Axon 7 for almost 2 years now, I am planning a trip to Tokyo for just over 2 weeks at the end of August and want to be able to get a sim in Japan and use my phone as normal. Now our Axon 7 u supports 3/4 of SoftBank lte bands and 2/3 of the other bands it needs. So this option doesn't seem too bad.
Now getting closer to my question.
International or us versions of the a7 all have the snapdragon 820 which contains the modem. This same chip is available around the world including Japan. So
Does the snapdragon 820 have different versions with different modems? Or is the software the reason only certain bands are available in different versions of the phone.
If the software decides which bands are available is it possible to edit it to unlock any bands I may want when I am in Tokyo this summer?
I am on unlocked bootloader twrp etc. and have used lineage os and other ROMs right now on a stock based room rooted
Any help and knowledge is appreciated. I googled around a bit and didn't find much on the subject
Simply having a chip that supports a band is not enough, it needs antennas that are properly modulated and shielded for that frequency.
Even if you were to patch the modem to enable a certain band, you would most likely not get reception at all or cause interference on other channels

I'm guessing you aren't too aquaintanced with custom ROMs and that kinda stuff for the axon 7. lemme explain.
There are 3 versions: A2017 (china), A2017G (Int'l, the one used in Japan i think), and A2017U (US). All of them have different modems.
The updates for each device all come with different NHLOS.bin files, which are the modem files. If you flash the U file on a G you won't have any signal. Sometimes you can even wipe out your IMEIs.
But why do you need LTE for a 2 week trip though? You'll get phone signal and data anyways...

I know all about the different versions of the phone, I've been around here for a while. My first question was simply if the 820 has different versions with different banded modems. After reading your reply I'm still not sure. Like I said I know about the different versions of the phone and the fact that they have different modem firmware. My question was hardware related, based on another guys reply it seems not likely it's there antenna that is the deciding factor in what bands can work as far as hardware is concerned which obviously means there is no possibility of unlocking any bands

What I mean is that installing different modem firmware basically makes the modem inoperable. hence, there are key differences between the models
I'm in Tokyo right now and get LTE on Docomo via band 3, which doesn't seem to be advertised anywhere. I was quite surprised! Speeds have been great!
Technically, it can work in Japan. It will get LTE in urban areas and a mix of LTE and HSPA+ elsewhere. From a practical point of view, the garbage radios in the Axon 7 are a serious problem if you're roaming. Hopping around on different bands and carriers causes the radio to constantly die, lose data, or lock onto the wrong cell tower. You'll have to cycle airplane mode frequently and you can't count on incoming calls/texts working.
I haven't had time to try LineageOS in Japan yet. It seems to have fewer radio problems so it might do OK.
Axon in Japan
Hey, I use a American Axon 7 in Japan with no issues, if you use any MVNO sim that uses NTT Docomo Network you should be fine, for example BicSim, IIJMio Travel sim etc.
