Hi, I know snapdragon 650 has cat 7 lte modem and is capable of lte-advanced which in my area is supported, also i have enabled all frequency bands of my snapdragon bands with QXDM,QPST and i see two frequency bands with network guru app but my phone can't do the carrier aggregation.
My guess: xiaomi must have done some thing to make it work
Any body has any idea how to make it work?
I have root access with resurrection remix ROM
Works for me fine on unofficial lineage without any tweaking, I had the LTE + icon showing and did a speed test and got 119Mbps

I'm new on this forum and maybe the question I'm gonna make was discussed before, but I wanna know if I flash my T-mobile T999 with another compatible OS version mod, it will get the 900mhz frequency in order to make it work on another country that use that freq or if is the hardware of this device does not support this.
It should work without making any changes to the OS as long as it is sim unlocked.
not work for 3G only EDGE

It works for voice calls (GSM) but on Data only EDGE not 3G.
Are you sure there is 3g on that frequency? If yes, then try APN settings or try to force HSPA only for data.
My carrier, Three UK has recently rolled out Voice Over LTE (VOLTE) in the UK since the LG G3 supports VOLTE (Hardware wise since it supports 800 Mhz on the LTE Band). The only problem is it is currently only working for devices that run on the Three firmware and I have the unbranded European model. I have the firmware as a KDZ file and it works, however VOLTE doesn't work on Fulmics ROM 5.3 since when I make a call it switches to 3G instead of 4G.
Since the implementation of VOLTE is software based is there anyway to port it over to Fulmics ROM?
Any ideas?
Hmm I might be wrong but I do believe this is the correct functionality of VOLTE. The voice gets transferred over the 4G connection, and you get to keep the 3g internet connection active simlultaneasly.
Otherwise without having 4G you would just drop the data connection while having the call.

Sorry to hijack your thread, but would you mind telling me how to obtain the correct firmware?
Three's website doesn't offer a VoLTE compatible firmware for the G3, but offers the workaround of using the Three inTouch app. I don't want to use that, because reviews of the app are not promising.
Hello guys,
I'm using USA stock ROM and the main drawback (for me) is the missing network icon that shows when you're doing carrier aggregation. In Taiwanese ROM it's indicated by 4G+ but there's no icon in USA ROM for this type of network so the only option to see if you're connected to two or more bands is rooting and using Network Guru.
As I'm not root and I don't plan to I captured a log using LTE Discovery in an area that supposedly have carrier aggregation using bands 7 and 28. From the connections that my phone made I noted that there're some connections to bands 7 and 28 in the same antenna (same PCI) in a short period of time.
Can I infer I'm using carrier aggregation? Before I transformed my HTC 10 to USA 4G+ worked with default Taiwanese ROM however with the USA ROM I can't verify this.
Please look at the screenshot I attached.
Thank you guys.

Turn off wifi. It won't show when you are connected to it because you are using wifi instead of mobile data.
Thank you for your reply. The log I'm showing was recorded indeed in a zone where I don't have WiFi connection and where the phone connected to B7 and B28 LTE bands (but not sure if it was doing carrier aggregation, using the two bands together).
Maybe you got confused as when I took the screenshot of the log I was in my house with WiFi connection.
Anyway what I'm saying is that USA stock ROM show 4G LTE icon for both, one band and two bands (CA) in comparison with TW that shows 4G for one band and 4G+ for two bands.

Hi, my lg g2 ls980 doesn't seem to work on 4g, even though the lte bands are supported by the device. I use a carrier which supports band 3, 5 and 40 and my device supports band 3 and 40. Sim card is also 4g enabled. Originally, the device didn't come with these bands. I added them using qxdm.
When i try to lock to lte using an app called Network Signal guru, it automatically changes to wcdma.
I've posted 2 threads about this issue before and got no response. Those who can help me, please do. It would help me a lot. Thanks!
ps: changing/updating modem doesn't help either.

I added lte bands using qxdm professional nv write tool. Check out the post on xda because it has very detailed steps. But the bands don't seem to work. I still dont get any network when changing to lte (bands show up in settings, though.) You might want to give it a try and maybe it could work. Btw now I'm using zenfone max pro m1 so I'll not try to rectify the problem anymore. Good luck

Yeah i know the post on xda but can u give the files n tools u used which application version? Only send the files u used to add the bands and i'll do the rest
The LS980's hardware (antennas, etc) only supports bands 25, 26, and 41. No software changes you make will add the hardware needed to support other bands.
I have the 64GB Global version
Last Miui 10.3.4.0
I live in Argentina, we use this four LTE bands: 2 - 4 - 7 - 28
The phone can connect ok to those four bands individually but I think don’t is not doing CA, not even 2CA
My previous phone Samsung A5 2016 did 2CA ok, I don't remember exactly all the combinations, but I think 7+28 and 4+28 for sure
First of all, how to see if Mi9SE is doing CA without root? I use *#*#4636#*#* and Cellular-Z app
The phone claims to support 3CA; but which are the available combinations?
Tested also the app "NetMonster"; there its shows up to 4CA which I think is fake, so I discard this app.
Thank you in advance!
Yes this device support 3CA, here is supported combinations: https://cacombos.com/device?model=M1903F2G
Yes Netmonster doesn't show correctly. There is app called Network Signal Guru what show real data but require root.
