Chinese and international dual sim variants and FDD LTE bands FDD B20 with dual sim? - Droid Turbo 2 Q&A, Help & Troubleshooting

I have found differences between Chinese sold X forces:
Then there are Brazilian versions and Mexican and then the single sims, that i'm not interested in. Are all these phones same just different modem firmware?
Is there somewhere all the different modem firmwares for download?
Is it possible to get dual sim with FDD LTE band 20 (800mhz)?

Given that the modem files differ, I'd say there is a hardware difference. It seems that the XT1580 has one extra (domestic China) LTE band.

[Q] Band Selection

Good evening,
Is there a service menu screen within the atrix like on the samsung galaxy s?
http://androidforums.com/samsung-ga...rk-frequency-your-samsung-i9000-galaxy-s.html
I want to see if there is a similar method to this to enable 3G on 900mhz on my AT&T Atrix as I've read in several places that this frequency is locked down simply by software and that the radios in the AT&T and world/bell/uk versions are the same chip.
I have tried flashing several radios (UK, and other world ones) to no avail. I would like to enable this band as O2 in the UK are putting 3G on 900mhz (equivilant to AT&T's "4G" on 850mhz)
Any ideas on if I can do this at all please?
Yes, just dial *#*#4636#*#*

That does not do band selection.

Flashback to one year ago, my XT1060 on T-Mobile HSPA+

Here is proof that band 4 was active on Jelly Bean 4.2.2 on the XT1060, though it was only on HSPA+, not LTE.
CDMA networks like Verizon report it as BC15 (band class 15, 1700/2100MHz), but it's AWS band 4. This is how I found out my T-Mobile area was NOT refarmed, and therefore, not compatible with older VZW global phones without AWS.

I can't see your picture, but you can see band data (w/o root) using the app "LTE Discovery".

will G928 model work on T-Mobile

I have the note 5 but have decided to get the edge + ,I can get the unlocked version G928 model on Amazon for $727 if I get straight from T-Mobile unfinanced its $779 plus tax. What I want to know is will the G928 unlocked model work on 4g LTE? And will other features such as WiFi calling work?
Anyone?
Unsure, Wifi calling may require carrier settings adding to it though that should happen when you insert the SIM Card.
Likely you have gotten a Factory unlocked jobby from somewhere though as all models are G928 the letters after this will help determine where it is from and what region it works with, as an example I'm in the UK and have a SM-G928F ... Thankfully not the Canyonero F model...

4G LTE/LTE+ in Europe with US version

Hey,
I bought galaxy s8 US unlocked version while traveling in USA it was flawless there, now I'm back in Europe. Everything works just fine except mobile internet. I can't get 4G LTE+ and having only LTE, which is slow comparing to LTE+. So I checked if there could be a problem with frequencies in willmyphonework.net.

It says that there shouldn't be any problems, so now I'm confused, maybe this is software problem, I mean maybe I need my region firmware in order to use 4G LTE+ internet, any ideas or suggestions?
Thanks

Sharp Aquos Wish2 5G work outside Japan

Hello, I have a Sharp Aquos Wish 2 (SH-51C) and I would like to know, if anyone has one, if the 5g network works. Unfortunately, I can't get it to work. Obviously, I have a 5g-enabled phone rate and I've checked all the settings. In addition, the phone should support the 700MHz and 3700GHz bands of the telephone carrier I use. Thank you
This model dosen't support 5G when it is outside of Japan.
Anothe model A204SH can suppurt N78, tested with 5G in Taiwan.

Thank you. I bought a Sense 7 SIM Free (SH-M24) and unfortunately 5G network doesn't work despite all bands are supported...
