Z1 C6902 can unlock LTE? - Xperia Z1 Q&A, Help & Troubleshooting

Today my Z1 start to connect to our carrier experiment DC-HSPA+ network. Speed look good, 35 DL and 27 UL Funny is when I google it AT&T say that's 4G but it's not .After some research But some page on the internet say that Z1 has capable of unlocking LTE band in baseband using method of ZR unlocking LTE by connect phone to QPST. Can anybody try that?

DC stands for dual cell HSPA+
Alternative method to double the data rates is to double the bandwidth to 10*MHz (i.e. 2×5*MHz) by using DC-HSDPA.*
So it is just different operation method.

Noticed from your screenshot that you're actually on edge (2g) network. I'm guessing you have different results because the page is loading slower than on your WIFI.

CM11 - Problems with 3G / 4G connexion

Hello,
:cyclops:
I've got problems to receive an internet connexion with my french 3G (or 4G LTE when It's possible) on my I9305 based on a CM11 nightly version.
When I'm with the wifi mode, no problem.
How could I upgrade the radio (or something else) ?
I've been into specific xda sub forum (to try to find solutions) but It seems to be too "high level" for me.
Here is my configuration (http://hpics.li/a4c33d4)

Verizon - high cell standby

I received my new Moto X (2014 version) a few days ago. I'm living in Manhattan, so we're pretty much blanketed with 4G. I'm normally around 3-4 bars in my office, but I've noticed that my Cell Standby in my battery stats has been anywhere between 20-30%; generally 0% time with out a signal. Any ideas? That seems pretty high to me. Should I try a factory reset? Would changing the mobile network from Global to LTE/CDMA help at all?
I'm getting the same. Is this normal?

Carrier Aggregation for AT&T

Anybody know how to make the T-Mobile N910T take advantage of AT&T's carrier aggregation? You know, like ban 4 + 17 or band 2 + 17 working as one?
Interested in this myself.
Sent from my SHIELD Tablet using XDA Free mobile app
So I did a little digging. These are the LTE bands and CA configurations the T-Mobile Note 4 can do. As you can see, it's mainly configured for T-Mobile's LTE network since AT&T's Band 17 (their main band) is not present in the CA list.

Weak or no signals on XZ3

Hi
I am using Sony XZ3 for around 15 months on O2 UK.
For last 4-5 months I am struggling to get good network reception. Changed sim card as well but no luck. I put my sim in my old HTC phone and not had any issues for 2 weeks. What is possibly wrong with the phone or network?
Screen shots attached via Net Monitor Lite app. Why it shows WCDMA connection on LTE or GSM sim?

Same issue. Reception is really bad against other phones.
We need to update the baseband.
