Hi guys, I'm the owner of the LG E980 by AT&T. I'm using it with the Telcel provider in Mexico, and i just can't change the network between 2g, 3g and 4g, or cdma and lte.All the time seems work on 4g or LTE mode.

AT&T Likes to lock that kind of thing down. Telcel is not cdma I think you mean WDCMA which is 3G.
Anyway if You have a PC and some good computer skills check out my thread to flash the Telcel rom on your E980 and the option under mobile networks is there and working thats the rom I use on my AT&T E980

3G connectivity on LG G3 D51 T-Mobile

I bought a refurbished LG G3 D851 T-Mobile from eBay. The phone is GSM and Unlocked, as the seller mentioned.
I tried to switch to 3G network mode, but couldn't. If I select WCDMA Only in network settings then I find no network signal at all. In our country we only have 3G connectivity and that's the only choice we have.
What should I do to get 3G connectivity? Any help?
Android version: 5.0.1
Build number: LRX21Y
Software version: D85120e
Kernel version 3.4.0

Thanks for your kind information. But living in another country using other network I can't just call T-Mobile customer support for help. I thought of flashing my LG G3 D851 ROM to D855 European general version ROM--so that I can active 3G connectivity. I want to know the process.

Hardware inside (radio, bluetooth, WiFi) are different. 855 firmware or rom will not work.

Thank you for your reply. Then how can I activate 3G in my smartphone?
Try Advance Signal Status app in the Play Store. If you are rooted, the advanced screen lets you change signal options.

yes sir
Will a GSM SIM work in that phone at all? Virgin Mobile uses the Sprint network, which is CDMA.

actually, I've flashed to cm12 nightly build latest version. after that it shows network in the network bar. but also shows a R beside the network bar. which means roaming.
I'm in Bangladesh.

Painfully, I have sprint CDMA, nothing has changed since I insert the sim available in Nigeria here.
I believe I need to change to GSM first then try to unlock sim with code.
I'm new to this kind troubleshooting, please can you guide me on how to solve this issue so I can be able to use the code to unlock.

VOLTE Question Concerning Fulmics ROM

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.

Samsung S6 Sprint CDMA USA SIM Unlock

Hello to XDA community, as for the title let me clarify on my problem.
Recently I bought a used Samsung S6 SM-G920P from a shop. Then I realise that its a CDMA USA version, it cant receive 4G/LTE network in my country ( Malaysia / Asia ) but it can receive the 3G network. I really want to enable the 4G network, what must I do? Perhaps unlocking the network band or anything? Im lost
Thanks for advance.
