Will an 4G unlocked ATT LG Optimus G work on Verizon?
Verizon 4G cards seem to be SIM cards so i was wondering if an unlocked 4G phone made for AT&T could possibly work on Verizon?

Verizon's network uses CDMA and AT&T's network use GSM, so an ATT LGOG won't work on Verizon. I believe that a Sprint version (LS970 IIRC) will work.

4g wont work on l9, on this phone you can use 3g(internet) segnal or 2g(sms and calls)
to use 4g you must have a phone that support this tecnology(HARDWARE)

Please make sure that after unlock boot loader you flash your original kdz back by offline method. I think it a incorrect baseband problem.

Yea my t-mobile L9 (P769) uses 4g as well, however I do not believe they are LTE capable (correct me if im wrong). Many people think 4g and lte are the same.However they are not.
my phone is lte capable. 4g LTE

That is not true. Not a single LG optimus L9 variant regardless of model or network supports LTE. However they are capable of running 4g just not 4g LTE. The 4g runs off HSPA+ not LTE. Even the LG optimus L9 II uses HSPA+ for the 4g network.
T-Mobile USA seems to define 4g their way. Something like gsm, umts, hspa & cdma, that makes four.

Thats all the radio bands the device can pick up. 4g acctually runs off the hspa. If you change your prefered network to gsm/cdma or umts only or auto it will not connect to 4 g. In order to connect to 4 g you must select hspa+ auto or wcdma+ auto. I couldnt connect to 4g when i first got my phone and its because the prefered network was set to gsm/cdma (auto). I get the best speed on wcdma+(auto). That will make it connect to the fastest radio band available. My phones a t-mobile but I unlocked it and switched to at&t because tmobiles data speed was horrible. I would average .20 mbps - 2.25 mbps (bits not bytes) with tmobiles 4g. On at&t I get 12mbps to 25 mbps and have even got as high as 40mbps right in town. Thats just in my area however, im sure tmobile has good speed in certain areas. After switching to at&t it made me miss my lg p870 I gave my girl because its LTE and she gets anywhere from 20-50mbps!?
I'm using the Verizon Wireless LG G3 on Cricket Wireless which is a GSM carrier that uses AT&T towers.
I've been using Android 4.4 with the 10b modem and my 4G LTE has been working great since I got this phone about 6 months ago. I have TWRP on my phone, so I went ahead and upgraded to Android 5.0 (with 23b modem) and no longer have any LTE at all. I can only connect to HSPA+. I did a nandroid back to 4.4 where I left off and I have my LTE back.
I know many of you are probably using your VZW LG G3 on Verizon, so i'm reaching out to anybody else who may be using it on a GSM carrier. Can anybody help me with this? I'd love to have Android 5.0 on my phone, but i'm not willing to lose LTE, so I'm back on my nandroid of 4.4 until I can figure this out. Any help is greatly appreciated...
Someone asked in the other thread you asked this if you kept your APN settings from your KitKat ROM, since they would be necessary to have the full network features on any other ROM / update.

Im jealous u have lte im on cricket and my phone was already 12b whn i got it also can you post your apn settings
My APN'S aren't the reason I get LTE. I get LTE because I'm on 10b radio. When I try to use the stock lollipop rom it upgrades my radio to 23b and disables LTE. I installed CM 5.0.1. nightly with 10b radio and I get LTE on Android 5.0 now, but only on CM or AOSP. I've tested all of the modems with my phone and I get LTE on Cricket Wireless with 10b and 11c modems, but absolutely no LTE with 12b or 23b. It's the radio causing the lack of LTE on GSM carriers. I think it's Verizon's way of still trying to carrier lock their phones a bit. I never had Verizon, I bought my G3 on craigslist for $100...
And it was me who asked that in another thread, my bad. Was just trying to get to the root of the problem and I did. I would still love to use the Stock Verizon based lollipop ROM with my phone, but it installs 23b radio which disables LTE. If I install the 10b radio while that ROM is installed, my signal will cut out every 15 seconds or so...
So i'm hoping someone can tell me how to install the stock lollipop ROM with a different radio, that would be fantastic!
Dang that sucks. I couldnt take it anymore installed the ota lsdt night and switched to Verizon prepaid

Well I did figure out if I use 10b or 11c modem that I get LTE on cricket or GSM networks. If i use AOSP or CM 5.0 based ROM I get LTE also without signal cutout. Just can't use the stock Verizon/LG based Android 5.0 ROM
I like cricket because they offer me 20GB of mobile data per month and unlimited talk and text for $60/month

That is a great deal for cricket. I checked my Phone LG G3 VS985 with cricket website and it says it only compatible up to 3G data speed??!!
I currently have T-Mobile with only 4GB and $55 per month.
I run my vs985 on stock rooted KitKat - not sure which radio I installed last - on both Cricket and T-Mobile pre-paid sims, sometimes, and I get great LTE on both, when available in the area. So, the Cricket website is just wrong about H+ only.
Also, AT&T wholly owns Cricket, which contains AIO now.

I am on T-mobile, and I want to share my LTE experience. The phone comes in 12b (Kitkat), and I can get LTE on band 4. I then downgraded to 10b (both ROM and radio), and I still get LTE, so both 10b and 12b radio should support LTE band 4. I haven't tried 23b yet as it is Lollipop 5.0.1 and it has memory leak issue that is to be fixed on 5.1.1 or later. I had 5.1 on my old Nexus 5, and the memory leak issue is very annoying. The apps will randomly hang and not responsive.

So, 12b radio does allow LTE on band4 like on T-Mobile ? Others say not on Cricket band4. I wonder which is correct if not both ?
Anyone can tell me how to check which radio version I have installed ? I thought it was 12b, but don't know how to see. I think it was to enable VoLTE, but I have never set that up on my account due to reports of transition difficulties.

Cricket is AT&T MVNO, and AT&T main LTE band is 17, which is not supported by VS985. Band 4 is a supplemental LTE band for AT&T, so it may not be available in many area. LTE band 4 is definitely supported by 12b modem.
My 10b modem Baseband version (last 5 letters) is NPZM-1. Maybe someone can report their 12b modem Baseband version here.
I get excellent high speed LTE on both T-Mobile and Cricket (cheap but throttled AT&T) everywhere I have tested here in NC and Virginia and Seattle. So band4 is not too rare on AT&T.
My modem ends with NPZM-1.7834.1 so it might be the same as yours ?
I think its pretty interesting that all the band 2 LTE is rolling out will work on practically no current phones except the N6 and some couple of Samsung variants. Hope the G4 will support it.
One of the reasons I hesitate to update to L is that I don't think anyone has found a way to enable the G3's band3 LTE yet on Lollipop and I want that for Europe travel.

I think your modem is probably 12b. My 10b modem ends with 1 without the ".7834.1", so yours is newer than 10b. Good that the band 4 works out for you on AT&T. I am on T-mobile, and my LTE speed is great too in the San Francisco Bay Area. I usually get between 20-30Mbps, but sometimes can go up to 57Mbps.
Nexus 5 supports band 2 too. About band 3, maybe you can try enabling it on 12b and then upgrade to L to see if it stays? I enabled band 3 on US version of Nexus 5 and it stays when I put new rom on it. Not sure if it is the same as Nexus 5.
. Could someone please help me find the correct settings to make A Verizon LG g3 work on AT&T 4G LTE in Birmingham Alabama. I have already gotten a SIM card that is supposed to work on unlocked phone from AT&T however for some reason I cannot get 4G LTE only H and when I use speed test it only runs a maximum download of about 6.5 mb/s where is the same sim card in my htc m8 will run an average of about 25 mb/s I have tried various APN settings obviously I'm doing something wrong any suggestions will be greatly appreciated thank you in advance
You Must be on 10b or 11b radio with a non stock (Cyanogenmod or AOSP ROMS) to get LTE working on AT&T. That's the only way I've ever been able to get LTE working on my VS985 on Cricket Wireless (which is owned and operated by AT&T). If I use a Stock 5.0 or the recent stock 5.1 ROM with the newer radios (12b and up) I will only get H+.
There is no fix for this that i'm aware of other then running Cyanogenmod and 10b modem.
The Verizon LG G3 (VS985) only contains LTE Bands 4 and 13 (plus the unlockable Bands 3 and 7). Band 13 is only used by Verizon, while Band 4 is used by T-Mobile and somewhat by AT&T in major cities. Outside of those major cities, you'll be on 3G (H+).
If you plan on sticking with AT&T or an MVNO of them, you should pick up the AT&T model G3, as it has AT&T's primary LTE Band 17, and Bands 2 and 5 that they use in some markets.
I have a Verizon LG v10 that I want to use on AT&T. Per Verizon the phone is unlocked, but I'm wondering will it be compatible? Will I still receive 4g LTE? I know someone who has Cricket. If I pop their sim into my phone, since it's supposedly AT&T, would that tell me how it will work?

Well I think I figured it out. Put in the Cricket card and all I get is H and no LTE. This Cricket card came out of a Verizon branded Nexus 6 and that got LTE fine. I think I'll just sell my Verizon v10 and pick up an AT&T v10.
