V10 F600K unable to find any network operators - LG V10 Q&A, Help & Troubleshooting

So I got an american sim card while im visiting the USA, so I popped it in my v10 f600k and for some reason when I search for networks here, my phone can find none at all. Whether I choose to automatically choose networks, or search and choose one, no operators are found. I have APN information in already for the t-mobile pin.
Anyone have any ideas to fix this? Pretty annoying, in Switzerland it works fine and can find multiple networks.

[Q] Travelling in Italy

My Dad has a MB860 (Bell version) that is unlocked. He is travelling in italy and pre-bought a SIM to use while he's there. We tested it here, and it looked like it was working. However, now that he is in Italy, the phone doesn't seem to connect to the towers (i.e. it says only Emergency Calls are allowed). However, he is able to send SMS messages.
We've tried doing a manual search for networks, and tried all the available networks in his area, but the problem still persists.
Is there a way to select the 900/2100 GSM bands?
Anyone have any ideas of what is going on or what to do next? He's getting a little frantic, not being able to call back.
Any help is greatly appreciated.

[Q] Vodafone data not working in Hungary

I have bought a prepaid SIM card in Hungary and am not able to connect to the internet, though I can call and text. The location where I bought the SIM checked their database and could not find my specific phone most probably due to the Photon being only available in the U.S. He looked up the Atrix as it is said that it is the closest to the Photon. They were supposed to send an SMS with instructions, but I never received them. CAN SOMEONE PLEASE HELP?
Have you tried connecting to Wi-Fi and using tweakker or apn global for the correct apn? Both are free in the play store.
I used a Vodafone sim in Romania and they have great customer service in their email center. I purchased my data plan at the Vodafone store, but with the photon you can't use the ussd codes that many operators require to select which plan you want. So the email center pushed the correct plan to my phone. Maybe try emailing Vodafone Hungary if all else fails.
Good luck.

Alcatel Ideal 4060a network Stuck at E/GPRS Please help

Hi am Haruna from Ghana.
I bought Alcatel Ideal 4060a (AT&T) model a couple of months ago, but problem is that the network doesn't change at all its always at 2g/EDGE no matter what i do or which network i put inside the phone.
Am currently using MTN (Scancom) which is a 4g Sim card and the phone is unlocked to any network.
And there is no option in the settings that you normally choose from your preferred network mode.
So i stated googling for the solution when i came across this code (*#*#4636#*#*) which i can use to change my preferred network, but whenever i change it, nothing happen, i mean nothing at all, all it does is that, when i select "only WCDMA" i will not get service/network, when i select "LTE only" no network, the only thing that work is GSM or WCDMA preferred.
So guys i urgently need your help as am getting frustrating by this phone.
E/GPRS is slow max u can get is 28KiBps, switch to 3g or 4g, it also depended on your att network coverage, Are you living inside bunker?

No service in Europe with Japanese SO-03F

Hi guys,
I own a Japanese Z2, originally by docomo (SO-03F) and flashed the English firmware I found in this forum (not sure for which area tho), except obviously the modem which I needed to use the docomo SIM.
I came back to Europe, unlocked the phone through an online service which worked fine but none of my SIMs can get a signal or behaves very weirdly.
I tried flashing the modem from the ROM I used before but then I couldn't get any reception and looking for networks through settings didn't show anything. With the Japanese ROM modem, I can find networks if I look manually but I can't connect to them. It shows "Selected network unavailable" and or "Can't connect to network at this time." after selecting the correct one.
I tried fiddling with the settings, different network types etc in the normal menu and in the one accessible through entering *#*#INFO#*#* but nothing helped. The phone number in the menu is shown correctly. As preferred network type, LTE/GSM/CDMA auto (PRL) is selected.
I have an older sim card in the right format which can't connect (works fine in other phones) but SOMETIMES I get like 2 bars for a few minutes. It's for phonecalls and SMS only. The internet only card I have is smaller so I need an adapter and won't connect at all. Is there something I can do about this?
Thanks a lot!

H961N Network Issue

My H961N does not allow me to independently set my network band for each sim card. Both my network providers operate on 2G/3G/4G however since I have gotten this V10 I have had inconsistent network usage. At first I would strongly get one network and the other would mostly be on Emergency Calls when indoors depending on where I was. I used the hidden menu code *#546368#*961#-> Field Test -> Modem Settings, from Modem Settins I have tried to set the RAT Selection and the Network Mode however when I check Engineering Mode both sims show the same band if I am on WCDMA Only or GSM Only but neither provider operators on the same band except for one on 3G. If RAT is set to selectively move between two or more frequencies then one sim shows Invalid Band in Engineering Mode. Using Network Mode I have tried to set each sim to different band but both would either show the same band or one would appear invalid under Engineering Mode.
Another Issue I have is I am unable to use data even though I have the correct APN for both of my Network Providers. I have verified that both sims do work when used in another phone, at one point I visited both Providers but none could give me an answer to my issue. One of my Providers did however try and activated a data plan while I was in their office and the V10 did show 3G and received data however upon returning back to my regular surroundings I no longer got any data. I have tried upgrading the V10 to Marshmallow and Nougat but the upgrade did not solve this problem, neither the one I stated before. But on Nougat both my sims did show 3G but strangely only when I have my Wifi active and using a VPN. Currently I am on Lollipop and rooted I considered trying to flashing a qcn, sec and nvm files since I saw a site listing them as fixing network and data issues on this particular phone, I have the files just in case. Any help would be greatly appreciated.
