AT&T N910A LTE Bands

Sorry if this is being posted before but I could not confirm an answer in google or xda forum.
Can anyone inform me if N910A (AT&T) Note 4 have Band 3 and Band 7?
AT&T website indicate B1 / B2 / B3 / B4 / B5 / B7 / B12 / B17 / B20 and B29
Samsung website indicate B2 / B4 / B5 / B12 / B17
I am using it in Asia and LTE B3, B7 are the only ones available
Thanks in advance

Can someone please reply to this.
It is a big problem for me also, since I have been in USA for some time now working, and now I am going back home to Croatia.
I read the same thing about N910A LTE bands on Samsung website, and then went to AT&T official website to international coverage troubleshoot and there it sad that note 4 should work in my home country on GSM/3G/LTE without any problems.
This is what they show about note 4 on their international troubleshoot:
NETWORK
- GSM/GPRS/EDGE 850/900/1800/1900
- UMTS/HSPA+ 850/1900/2100
- LTE Bands 1, 2, 3, 4, 5, 7, 12, 17, 20, 29

OnePlus 3 USA Variant in Australia

Hi All,
Paranoid purchaser here of the new oneplus 3, using a freight forwarder via USA to Australia (comgateway), i have used them before and they are very efficient, purchased oneplus 1 and the oneplus 2.
looking at this : http://willmyphonework.net/ , it looks like it will work here, only missing band 28 700mhz,
any1 else going this route? i do know there were work around to enable further lte bands on the oneplus 1 and 2
i didnt have a issue getting reception with either of those handsets,
any info is greatly appreciated

Both handsets previously had band 28 . If you use Telstra or Optus then dont buy! Band 28 very important for great 4g coverage with great speeds.
Not buying just for that reason. The way to enable the band 28 is very hard or non existent. Good luck either way.

Hi,
Are you sure both the OnePlus One and Two had band 28? According to these links neither had it:

Australian frequencies vs. OnePlus frequencies
From what I can find;
The frequencies used in Australia are;
from whirlpool . net . au / wiki / mobile_phone_frequencies
optus: 1, 3, 7, 28, 40, 42
telstra: 1, 3, 7, 8, 28
Vodafone: 3, 5
NBN: 40, 42 (42 is currently in trials)
The frequencies the various models of OnePlus 3 use are;
from oneplus . net / global / 3 / specs
US Model: 1, 2, 4, 5, 7, 8, 12, 17
EU/Asia Model: 1, 3, 5, 7, 8, 20, 38, 40, 41
China Model: 1, 3, 7, 38, 39, 40, 41
Looks to me like the EU will be the best option, then Chinese, and US last.

4G+ Not working with bands 1800+2600Mhz

Hello dear XDA Devs, I have a Big problem with the Xiaomi Mi Mix 2 with the 4G+ it cant aggregate with 1800+2600 bands in my country (France) with Freemobile (Carrier). It works correctly with 800/700+2600. And for me this is anoying. Can Someone explain me why this is not working ? or if there is a tool to flash the modem ? Maybe I can wait for the next Android Oreo?'
to know which bands I am using, I have rooted the phone and use the Network Signal Guru app
⚠⚠⚠⚠⚠⚠⚠⚠⚠⚠⚠⚠⚠⚠⚠⚠⚠⚠⚠⚠⚠⚠⚠⚠⚠

I can't find any specifics on the Mix 2's carrier aggregation specs, but it's possible that the combo you're looking for just isn't supported. I recall that my old ZTE Axon 7 had carrier aggregation for bands 2+4 but not 2/4+13, so Verizon customers here in the USA only got partial CA support.
Of course, I'm only speculating...I could be wrong and perhaps there's a mod via QXDM or something that could enable additional CA support.

Hi, There is no any programs which you can use to switch on additional bands. The truth is you should have check which bands mobile you want to buy support. Each mobile has a modem and this module decides which bands are aggregated.
Once again. First check and next buy.

The Xiaomi Mi Mix 2 is a cat. 12 LTE, this is verry good. Not the best for sure but with cat. 12 you can do 3xCA.
All LTE connectivity details from Xiaomi website.
Supports high-quality VoLTE calls
Network bands
4G: TD-LTE 34 / 38 / 39 / 40 / 41
4G: FDD-LTE 1 / 2 / 3 / 4 / 5 / 7 / 8 / 12 / 13 / 17
18 / 19 / 20 / 25 / 26 / 27 / 28 / 29 / 30
B41 supports full 2496 MHz - 2690 MHz bandwith
LTE B41 4-antenna technology supports 4x4 MIMO
Having a little talk with a few people who are familiar with Xiaomi's ROMs, this may come from the baseband, and this could be corrected in a future official update of MIUI. I hope
I have tested theses configurations in Network Signal Guru APP:
ISP: Freemobile have 700, 1800, 2600 for LTE
ISP: Orange F. have 800, 1800, 2600 for LTE
1 Band
700 Only: Works
800 Only: Works

Yes, I haved tested to make changes to the CA_BC_CONFIG and others parameters in QXDM but this is not working, looks like xiaomi uses another configuration parameters.
Saving values in QXDM works but don't change phone state and don't solve the carrier aggregation problem...

I confirm. B3+B7 don't work. (italy, vodafone it)
Xiaomi solve the bug pleae. Snapdragon834 support 4CA and xiaomi support 1CA.

Yes I read that last week, but I did a live chat with Samsung support on Tuesday the 13th and was told it would not support band 71 after being told the week before it would. I have been told 2 or 3 times it would not support band 71 and told about 2 or 3 times it would support band 71, I Made several phone calls and live chat with Samsung support over the past 3 weeks. So, I just wanted to let those know the supported bands that I saw in the hidden menu when I received my phone today.

Thanks uzupan. Did you put in an existing sim card, or get a new one for your S9? Trying to figure out if I will need to get a new one, or if I can use my old iPhone 6 sim....

Yes, I found that out.

With this service mode have you tried selecting band 71 to make it the default? I've tried this on my Galaxy S6 and only band 4 of my available bands on this phone was active in my area. If I selected any other band then I had no service at all. So went back to automatic and left it there.

Will it work in US and where to buy?

Does any one know whether the Realme 6 Pro will work on T-Mobile in the US? Also, where will it be available to buy and when? I searched Amazon, but only found the previous gen. Thanks in advance.

I would like to know as well

Here are the bands -
2G bands GSM 850 / 900 / 1800 / 1900 - SIM 1 & SIM 2
3G bands HSDPA 850 / 900 / 1700(AWS) / 1900 / 2100 - Global
HSDPA 850 / 900 / 2100 - India
4G bands 1, 2, 3, 4, 5, 7, 8, 20, 28, 38, 40, 41 - Global
1, 3, 5, 8, 38, 40, 41 - India

So is that a yes or a no from a actual user?
