[Q] No Band 12 for AT&T & TMO - Xperia Z3 Compact Q&A, Help & Troubleshooting

Question here. I was doing some digging. I should receive my Z3 compact phone today. I read that both it and the Z3 phones do not offer band 12. I currently use Straight Talk running off the AT&T bands. Apparently, in 2013 AT&T announced that they picked up band 12. Here is the breakdown of bands used between AT&T and TMO;
AT&T:
4G-LTE Bands 1, 2, 3, 4, 5, 7, 12, 17, 20, and 29
4G HSPA+ with enhanced backhaul
3G - UMTS 850/1900/2100MHz
GSM/GPRS/EDGE 850/900/1800/1900MHz
T-Mobile:
Quad Band GSM; UMTS: Band I (2100), Band II (1900), Band IV (1700/2100), Band V (850); LTE: 12, 1, 2, 3, 4, 5, 7, 8, 17
Is the lack of band 12 causing any issues with Z3/Z3C users using AT&T?

No issues.

I need Band 20 for Europe Digital Dividend - and UMTS 900! The Sprint version has UMTS 900, but no Band 20
I'm afraid the S5 is not a true world phone....
4G-LTE Bands 1, 2, 3, 4, 5, 7 and 17
1 2100 (Japan, South Korea,
2 US PCS 1900
3 EU/ASIA DCS 1800
4 US AWS
5 US CELLULAR FREQ
7 2600
17 AT&T 700
4G HSPA+ with enhanced backhaul
3G - UMTS 850/1900/2100MHz
NO UMTS 900 This is the biggest loss, as some areas ONLY have UMTS 900, no GSM 900
GSM/GPRS/EDGE 850/900/1800/1900MHz

So will one model work on ALL major carriers unlocked?

Really really hoping for this [emoji24][emoji24][emoji24][emoji24]

Yeah, the North American version will work on the four major in the U.S. with full LTE support.
Carriers will likely still lock the device (except Verizon which keeps their phones GSM unlocked)

Oh no I'm sure AT&T and the like will lock theirs but will the one sold by Google and Moto be fully unlocked and able to be used on all major carriers including sprints? [emoji39][emoji39]
when you say "global model" is that in a sense like a Nexus phone can be bought from any shelf and have any sim inserted into it and work?

Yep. It'll have the bands.
T-Mobile will likely remain unlocked, they have in the past with the N4 and the N5, I do not see any reason why they would start doing things differently for the N6.

There are 2 versions of the Nexus 5. One that Works on most of the carriers in North America. Another that works on most of the carriers, everywhere else. Typically called "international". The 6 will be similar.
The US Model will also work with MANY international carriers.

Is T-MOBILE's NOTE 4 4G/LTE, compatible with EUROPE's 1800MHZ frequency?

Hi Guys
I'm from Macedonia,Europe and I have a chance to buy tomorrow cheaper NOTE4 from T-MOBILE or VERIZON.Since VERIZON uses CDMA frequencies,can you help me by clearing things up:
Is T-Mobiles NOTE 4 compatible with my carriers frequencies here in Europe? I think that it is GSM and that the voice calls will not be problem,but is 4G/LTE compatible here?
My carrier is ONE and they told me that their 4G/ LTE uses 1800MHZ (bend 3 I think) and 800MHZ(bend 20).
-------------------------------------
Here is TMOBILE'S NOTE 4 specs from their website:
International
Quad Band GSM; LTE: 1, 2, 3, 4, 5, 7, 8, 12, 17; UMTS: Band I (2100), Band II (1900), Band IV (1700/2100), Band V (850)
--------------------------------------------------
This is from VERIZONS NOTE 4:
Network: LTE Band 13/4 (700/1700 MHz), CDMA/1xEVDO Rev. A (800/1900 MHz); Global Network: EDGE/GSM (850/900/1800/1900), HSPA/UMTS(850/900/1900/2100)
-------------------------------------------------------
Please help me and tell me if any of the models is compatible with my carrier in Europe,because it is urgent!!!
Thank you in advance
I have found a picture supossedly of TMobile's Note 4 back retail packaging.It says that it supports 1800MHZ in "OTHER LTE frequency".Can anyone of you that owns Note4, confirm it is original picture and that it really supports 4G/LTE 1800MHZ frequency????
It is urgent....

Will the Mi5 come with unlockable LTE bands ?

As I've come to believe from various sources the official supported bands are as follows:
4G FDD-LTE bands 1 / 3 / 7
4G TDD-LTE bands 38 / 39 / 40 / 41
3G TD-SCDMA bands 34 / 39
3G WCDMA bands 1 / 2 / 5 / 8
3G CDMA 2000 bands BC0 / BC1
2G GSM bands 2 / 3 / 5 / 8
2G CDMA 1X BC0 / BC1
Now since I live in europe .. my ISP's most used 4g (LTE) band is 20 (800mhz) and so it is not supported..
Will it be possible to unlock this band via QPST - QXDM modification, or has the band been disabled on the hardware side of the chip itself ?
I know it's very early on, but I have been anticipating the arrival of MI5 for months now, only to find a lack of european LTE support ...
thanks in advance for any info !!!
I also wonder this! Would be great for the 4G coverage here in Europe!
I'm also curious about this. If LTE band 20 is unlockable I'll buy one right away
It would be nice to know if it would be possible. I am also very interested in this phone
Here is answer from official support:

We'll all just probably have to wait until someone has one in hand and can test some different SIM Card to see what it actually will support... Needless to say though is if someone at least tests with either a TMO SIM or ATT SIM and they work.... one can assume that all 18 bands do... now it's a waiting game

I'm pretty sure it will not have all of those bands. Out of luck if you want to use this and are on Verizon, Sprint, AT&T or T-Mobile.
They just updated the supported bands and they have some of my country.. But I don't understand quite well the difference in the 800hz to 1800 to even 2600.. if for example my device catches the 1800 band but not the others, will the signal be good, or to be perfect in need to pick them all?
Also, higher frequency means better signal?

It won't support AT&T LTE?
Sent from my BLU LIFE ONE X using Tapatalk
Yes is it confirmed ! But if many people say it Xiaomi can't make Lte Global because Samsung and Apple don't want this...
But I'm sure it's not hardware but software and it possible to unlock this ?
And Xiaomi wont to shop in international but in late 2017 and this MI5 there are Lte Global in late 2017 Sorry for people want it me to
The question has not actually been answered: is anyone aware of any possibilities to unlock, via a kernel perhaps, the bands which should be supported by the hardware?
There's a good chance if you can unlock bootloader, Hugo Barra said in an interview that the India version will have those unlocked and not the model sold in China.

Nokia 8 LTE band choice

Hi there
I use my Nokia 8 on Telstra in Australia, and Telstra operates on LTE bands 3 (1800 MHz), 7 (2600 MHz) and 28 (700 MHz).
However, I notice it would often move onto band 7, despite it being the weakest band in the area, as shown in the attachment.
Any ideas why this happens? Is there any way to fix it?
