Hi, I am currently using the VZW Google Edition ROM 5.9 and have service and WiFi. My problem is it only connects to 3G, and not 4G. As advised, I have not gone into network settings, but I did open Phone Info and see that it is set to LTE/CDMA auto. Any reason I am not getting LTE?
Just a thought, but maybe you could check the APN settings and see if they are different than what you should have.

Thanks for the response. I am kind of new to this, where do I check the APN settings and how do I know what I should have? Thank you.
Do you have LTE coverage in your area? If so, can you use another phone/friend to double check if LTE is working? I only ask because we had LTE go out where we live.
Gir brings up a good point, I don't have 4G where I am (and probably won't for years!), but that may be simplest as long as they use the same network (although many carriers piggyback off the same network).
The APN settings should be under "Settings > More networks > Mobile networks > Access Point Names". On a stock ROM you have to get to the actual file through ADB, you should be able to see it if you have an aftermarket ROM. The settings for the APN will depend upon Verizon. Here is a good post with APN settings for Verizon, the first part is for Android.
Coverage could always be the issue as that has plagued me more times than not.
From the ROM thread:
Go into mobile network settings.
Verify that your CDMA subscription is set to RUIM and not NV.
For good measure go into the rest of the options and set it to CDMA/LTE, automatic, and allow data roaming.
Back out to your home screen.
Then go into Phone Info app.
Scroll to bottom and tap radio off.
Open the drop down list and select CDMA/LTE auto (PRL).
Turn the radio back on.
Reboot.
Upon reboot open Phone Info again.
Verify it is set to CDMA/LTE auto (PRL)
** you should have full service now * *
** if not * *
In Phone_Info(*#*#4636#*#*):
Try CDMA auto (PRL)
Then try CDMA/GSM/LTE
If those still don't work then your nv_data needs reset. The only way to do that is in the hidden menu dialer codes in a touchwiz-stocktype rom
If you destroy your nv_data and cannot get data back via the above you need to (stop screwing with your network settings)flash back to a TW ROM, enable hidden menu, and do a NV data reset via dialer code. After doing that make sure your phone is not in modem mode under diag dialer code. Until I update this section Google is your friend. And it is available information, verified. Your lack of searching skills doesn't mean pester my inbox...
I do have LTE in my area, as I had 4G before I loaded the rom. I do not have an APN menu under mobile networks. Do you think it could help to dial *228 option 2 to update roaming? Or possibly a new 4G sim card?
Anything about updating I would research first and be wary of... A new SIM card could help, but I'm assuming it is not the problem. Did you make a NANDROID before you changed ROMs? You could then go back and see it you still got 4G to make it evident if your SIM card is the problem.
FIXED
Just needed a new sim card. Thanks guys. I appear to be receiving signal bars with my LTE on the GPE rom as well.
Guys i am having a problem finding the apn options on my sprint lg, The phone is unlocked for any sim, but im trying to get my 3g to work on this phone but is this option even Available?
It is under Settings / More / Mobile Networks
Then choose Network Mode
I guess if you just select CDMA, you will be forced into 3g only.
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!
Hi guys I'm on vodafone network,Internet doesn't work on 3g,Works only on 4g.Since 4g network strength is not so strong in my Area my phone switches to 3g & Net stops working.I tried this code *#*#4636#*#* but it doesn't work.Is there any method to permanent select 4g.In settings there is only option for Lte/3g/2g.
Thanks for your time.
I do not know the dial code, but can open the menu with this app:

Thanks Bro
My native cellular operator has very bad internet speeds.
However, when i'm in some area which isn't covered by my native operator, i'm able to use network of other cellular operator, whose network is so much better - but i'm able to do it ONLY when there is no my native operator coverage.
My question - is there any way to be always connected to that other operator? If i select it manually, it quickly switches me back to my native operator.
I'm ready to root my phone, if there is any way to do it - I have Xiaomi Redmi Note 7.
Thank you in advance
Have you tried changing the APN?
yes... phone is still on native network
By default, in "Mobile Network Settings" network operator is set to "automatic". But there's an option to "manually select". This will then scan for available networks, and let you chose one (obviously only possible with the desired network in reach). Having done that, whenever the chosen network is not available, you'd simply have "no network" – it wouldn't switch to any other operator, however strong his signal might be.
At least on Android Nougat this works ...
