[Completed] Problem with lte on my xperia x - XDA Assist

Hello,
I'm actually from Germany, but i find this forum very useful..thats why i hope, you can help me with my problem.
I purchased a Sony xperia x online. Everything works fine except the LTE. It's very bad and unstable. I used an iPhone 6 plus before and there was no problem with lte.
I checked every setting, but everything seems fine.
I checked with the app Lte Discovery which lte band the device uses for lte connection and it said band 20. So i can be sure it has the Lte band 20, can't I?
I also found out on xpericheck that the installed firmware is for devices from switzerland.
So I want to ask you, if it's possible that the device doesn't really support band 20 because it's from another country? I haven't found any model of the xperia x online, which doesn't support lte band 20.
I would give you some screenshot but the forum doesn't allow me to do this.
Thank you in advance

[Q] Use LTE of an American Android Device in Europe

Hi guys,
I bought a Moto G LTE (XT1040) in Colombia because my old phone broke there. I thought there'd be no problem using its LTE capacities in Europe as well. Bad luck. It doesn't since in Colombia/America they use different bands. Is there a way to make my XT1040 use European bands, just like the XT1039 (European Version) would? HSDPA+ works fine.
Some facts that might help:
The phone XT1040 only takes bands 4 and 7 (at least it says so on the box).
According to my provider, I'd need bands 7 and 20. But 7 isn't in use here in Germany yet, and in cities hardly ever will.
I haven't been quite successful in the Moto G forum here. But maybe it's also a rather general question that applies for other Android Devices as well. If I posted in a wrong forum, I'd ask the mods to move that thread accordingly.
Thank you in advance for your help.

Oppo r7 Plusm LTE inquiry

Hi,
I'm new to posting on xda, been using it for advice for ages but this is the first time I haven't been able to find my answer. So I'm going to apologize if I've posted this in the wrong place or done anything else incorrectly right now.
I ordered an R7 plus from Taiwan and received it a few days ago. A great phone, i am entirely in love with it. I can put up with the bits of scattered chinese in the settings as i will be flashing cyanogen as soon as it's available. My problem however lies in the connectivity. I didnt know a whole lot about wireless data before ordering the phone, but what little I did know I applied to my research and found that all three variants of the phone should work on my providers network. I have the Taiwanese variant, which does supposedly support the 2100mhz, and 2600mhz frequencies, which i believe are bands 4 and 7, anyway, these two frequencies are the frequencies my provider uses. Rogers uses FDD with 2100 being up and 2600 being down. Yet in the phone settings when selecting which LTE band 4 and 7 arent options, there's USA Band (Im unsure what this really is, I assumed it was 4 because much of the us uses band 4), 6, 33, etc. And I havent been able to get LTE to work. The APN is configured correctly. All anyone's been able to tell me is that it should work. I can provide any more information you guys need, but any help would be greatly appreciated.
Edit: For more info- My provider is Rogers, i have also tried it on Bell (still only 3g), and Wind, which works the majority of Chinese phones and it didnt even pick up their network. Any advice would be great!

[Completed] Increasing the supported bands or frequency on Chinese phones?

Hey all,
So I recently have been looking into Chinese phones and have realized that there are some great competitively priced phones on the market, in particular I am interested in the Lenovo Lemon k3. However I have T-mobile, which support Bands 2, 4 and 12 for 4G LTE, most Chinese phones however do not support those bands. I was wondering if its possible to root and then mod any of these phones to support all Bands, I dont want to buy one and be stuck using 2G coverage.
Thanks,

Xperia Z5 Compact not receiving 4G signal with Rogers Canada

Hi everyone,
I just got my Xperia Z5 Compact from my dad, but the problem is that I can not get 4G signal with Rogers Canada. My Z5 Compact was bought from the US
I asked support from Rogers and they said since Rogers does not carry the Xperia Z5 Compact, and my sim is working properly with other phones, they cannot offer me help.
My phone current settings:
- Preferred network type: LTE (preferred)/WCDMA/GSM
- Rogers LTE - Itemobile.apn
Can someone help me? Thank you!

Check if the bands and frequencies of your carrier match the bands and frequencies supported by the device. There is more to it than just it being 4G LTE. If bands and frequencies don't match, it won't work.
Also, your radio/modem may not be compatible. Some devices that move to a different network have to flash a modem to work on the other network. That doesn't mean that a compatible modem is available for your device though. Some devices switching networks have to live without 4G because the device hardware just doesn't support what the network has regardless of what software you apply.
I DO NOT PROVIDE HELP IN PM, KEEP IT IN THE THREADS FOR EVERYONE TO SHARE
A USA purchased X5 Compact has all the LTE bands that Rogers uses. As long as the APN settings are correct (and I'd assume that these settings come from the SIM card), the phone should work. Does it work otherwise, just not with 4G?

XT1643 LTE Network reception problem in US with an Indian device

Hello,
Im using Moto g4 plus 32gb version in USA which is bought in India few days ago. Also im using Lycamobile carrier here in USA. My problem is im not getting an LTE signal on my device while i changed settings to LTE recommended and others in my area are getting LTE signal for the same carrier. Am i missing something here or is the fault that i brought this device from India that's not supporting LTE bands in USA. Is there an app in playstore for network unlocking compatible to bands in the U.S. Could anyone please help resolve the issue.
P.S. i updated the device to Android N 7.0 through OTA after reaching U.S.A.
Check your compatibility with Lyca.
