Get AT&T LTE working on VS985 Verizon G3 - G3 Q&A, Help & Troubleshooting

My nexus 5 died and i need a new phone. I have a Verizon LG G3 that I can use but I cannot get it to see LTE, only HSPA on AT&T.
I did some research and it seems I need to unlock carrier frequencies, or something similar.
SInce the phone has TWRP and is unlocked, is there any specific ROM I can flash to unlock all carrier frequencies? I really liked that with my Nexus nearly anywhere I went in the world I could just buy a sim, pop it in, and go. No hassle.
Thanks for your help in advance.

LG G2X unlocked but no 3G on GSM

Canadian here,
I picked up an LG P999DW Optimus G2X (Optimus 2x) Link and I unlocked it with the Octopus. I have put in a Rogers(GSM) Sim and I cannot get it to work with 3G even after I put in the correct APN settings. Can anyone help me get 3G working please?
Thanks,

Bump, can someone please give me a hand with this? 2g is terribly slow
Make sure the phone and sim are cooperating
I'm sorry to hear that you are having issues with getting the right network, but you might wanna check with the phone's hardware, and ask the people who you bought it from. I remember my brother got an iPhone 4S unlocked straight from Apple store, and even though the iPhone 4S supports at least 3G speed, my brother is not getting the 3G speed because he is using a T-Mobile powered SIM, not exactly T-Mobile. At the same time, I use that exact same SIM on my HTC G2 and I get 4G/HSPA+ speed, so it clearly depends on the phone.
The phone itself and the SIM has to cooperate in order for you to get the speed you deserve for that phone.
Hope that helps, I don't know much but I've noticed it a lot.
it all depends on bands, most unlocked devices only get EDGE(or 2g) on other networks it will only get 4g or 3g on the device the carrier it was made for unless the phone was made otherwise

I have the same problem. Unlocked P999 from Wind and I'm using it for Fido (Rogers network) but I can only get 2g.

What is the model number for the unlocked US LG G3?

I'm thinking of buying an LG G3, but I wanted to know what the USA unlocked (no carrier) model number is, and I've had trouble finding it. Any help?

You've had trouble finding it because it doesn't exist.
What carrier are you looking to use it on?

Consumer Cellular. I have to buy my phones off-contract to use them with my carrier. It runs on AT&T's network.

Ok you'll probably want to use the T-Mobile variant and get it unlocked. You don't actually want to use an AT&T phone on an AT&T MVNO (like Consumer Cellular), because the intrusive AT&T bloatware doesn't leave you alone, but it's useless on anything other than AT&T itself (AT&T Address Book is particularly vile). T-Mobile's bloat is lower key and tends to go away if you want it to.
The T-Mobile variant (D851) will support HSPA on the frequencies Consumer Cellular uses. It also supports LTE Bands 17, 4, and 2, which Consumer Cellular/AT&T uses. The only problem might be LTE Band 5, which the D851 does NOT support. That's the downside, though thankfully AT&T doesn't seem to be using 850 Mhz for LTE all that much.

Thank you for that info! But also, are both models able to be rooted and bootloader unlocked? I'm a huge root user and I always uninstall bloat anyways. But I want to make sure that I can also unlock the bootloader so I could install a custom rom like CM11.

The T-Mobile version's bootloader is unlocked, the AT&T one is not. Both have been rooted at this point, but LG's big on not updating rooted devices, so I haven't bothered rooting. I don't know if the G3 will actively block updates on a rooted device like the G2 and OGP did, but it's certainly possible, and I won't get enough from rooting that I actually care about to make me want to try.

Wait so are you saying the T-Mobile version comes bootloader unlocked, or tha you can't unlock the AT&T's bootloader?

Only the T-Mobile model is bootloader unlocked. Every other model is locked down currently.

The AT&T D850's bootloader is locked. I have one. I'm also a huge fan of Rooting and loading CM11, but the new LG interface isn't bad enough to make me do all that. Unlike the Touch Jizz Crap I had on my S3 with Sprint. I couldn't root that phone and load CM11 fast enough on that device. It's a shame too, the S3 is actually a really nice phone for it's time. The G3 actually runs pretty smoothly and the bloat wares aren't really in my face all the time. The only one I find annoying is that freaking ATT address book crap which will some day force me to root this phone and kill it. Good thing that the Root method is already available for the Verizon and ATT variants of G3.
Some one said you won't be able to find the US unlocked version of the G3, he's right so far. I was on that boat too. I couldn't wait to get my switch to the new G3 and Amazon, Bestbuy, or even freaking going to the phone stores such as ATT or T-Mobile would sell it. I forgot to think of ATT and T-mobile as a service provider instead of a phone store because they obviously only wanted to sell plans and the phones are pretty much accessories of those plans.
Anyways, long story short, I got my unlocked G3 (ATT version) via ebay. Then I used it on Straight Talk. Everything works the way they are suppose to and I am getting ATT LTE speeds too, just at half the price. There are only 2 things that doesn't quite work. One is sending and receiving MMS. The other is visual voicemail. MMS thing, I still have to call straight talk up and deal with their infamous customer service. The visual voicemail thing, I just use youmail and it works ok and an alternative. Some ads here and there, and the interface isn't the best in the world, but at least it works. It's a shame that LG doesn't sell their own unlocked phones via their own website like HTC does.

Use Verizon LG G3 on AT&T

My Nexus 5 phone broke but I have a Verizon LG G3 laying around the house. I rooted it and flashed TWRP on it. How can I get the AT&T LTE bands unlocked? Is there any ROM that can convert the Verizon model into a International Model, or at least unlock all of the frequency bands? Right now only HSPA works.
Thank in advance for your help.

Verizon G4 to ATT without modding?

I have a unmodded Verizon LG G4 with Marshmallow 6.0. What would happen if I just took the sim card out of my ATT Moto X and put it in the G4?
Would I get anything close to LTE speeds? What wouldn't work?
If I rooted the V-G4, what would that help to do? It it necessary?
thx.
Well the phone is unlocked for GSM, so you should be able to use it on ATT. Just pop the sim and see.
In future, just check this website: www.willmyphonework.net
It works after inputting the ATT codes, but gets the "H" band instead of LTE.

SIM unlocked T-Mobile Z2 Force - on Verizon?

There are a ton of entries on XDA about sim unlocking the T-Mobile and Sprint versions of the Z2 force, but none of them confirm once unlocked if they've used it on Verizon.
T-Mobile's page confirms their version utilizes bands 2,4 and 13 - all of which are Verizon's LTE bands.
Can anyone confirm?
I'm looking to buy this to replace a work phone on Verizon. My personal account is with T-Mobile, so would be very nice if I could just flip sims whenever I'd like. Appreciate in advance the responses!
(unlock T-Mobile bootloader, sim unlock, root and put a custom rom with safety net passes)
then type this on google and try.

Oh if this works I would be so happy to switch back to VZW. Anyone attempted it yet?
I'm interested in knowing if anyone tried this too
I’m too chicken to mess with anything not official from xda on my daily driver. I’m sucking it up and waiting out the period for the device unlock app to ‘officially’ sim unlock and try. When that day comes, I’ll post here.
I think it’s ignorant having to wait for a sim unlock for a phone you bought outright.

Eagerly awaiting news on this - why is there a waiting period on the sim unlock? How longs is that period? I'm about to head out to Tmobile store and buy me one too.
Verizon's LTE band 13 is exclusive to the Verizon model unfortunately. I wish it wasn't so you could use a bootloader unlocked Sprint or T-Mobile edition on Verizon. I did that with the Google Pixel - used the universal one on Verizon. I just got used to having an unrooted phone with the z2 Force. I switched to blokada after many years of always using ad away. I think most all ad blockers on unrooted phones are VPN based so it lags WiFi and mobile data a little but that's what you get to work with if you want the best moto phone running on Verizon.

Could you provide your source of information on that? T-Mobile's listing of the Z2 Force lists band 13 LTE capability, and multiple sources say that the Sprint variant has band 13 too. I am just about to pull the trigger on a Z2 Force variant that is bootloader unlockable, but whichever carrier version I get has to work with Straight Talk Verizon.
I'm seeing the sprint one listed as having band 13 now everywhere actually. My bad. I don't recall seeing that back when i got it and was shopping around. Let me know if the Sprint one works for you on vz because i miss having a a rooted phone.
The only different thing on the US phone's is the oem partition. Everything else hardware and software are very similar to the point I want to say identical. (Obviously, some slight changes in /system and stuff but that's with the territory of using OEM ROMs). I have flashed a T-Mobile flashall and it worked. I flashed back to Sprint shortly after. I did it for science.
So in short, will am unlocked T-mobile Moto Z2 work on the Verizon network with a sim swap? Or does it require a root or the bootloader thing that was mentioned, I haven't done either one as I am content with factory.
So, what's the verdict? Will unlocked T-Mobile Z2 force work with Verizon?
Most likely will not work. T-Mobile variant is GSM and most likely doesn't have the CDMA bands on it or programmed into it. Only thing you can try is flash Verizon firmware and see if it works. 99% chance T-mobile firmware will not work, Verizon firmware has about a 40% chance of working. If you don't have the device, I'd suggest not investing as no one has tried it.
I tried the Verizon flash all on my TMobile z2. Didn't work.lost baseband.
The flash all looked as if everything flashed properly...but when it finished and rebooted it still had tmo splash screen. So I don't know if it really did it.
If it's worth any thing my Verizon Sim in my tmo z2 gets great data...just no calls/messages
I have an unlocked Sprint variant that I flashed to Verizon and use with Straight talk Verizon. The only issue is that so far whenever an update comes in I have to back up all the things I want to save and flash the updated flashall, because the automatic updater just keeps on failing. I don't know if this matters, but I'm bootloader unlocked (had to for sim unlock) but without TWRP or root. It's possible that if I would try relocking the bootloader that the automatic update process would work. I briefly had a Mint sim in there (T-mobile) and everything seemed to work. I didn't really try things out with the Sprint rom, but as I remember everything worked, I just didn't like the icon style plus always having a notification saying something about a non Sprint sim card

Was it officially unlocked or was a modified file flashed to your phone? If you had a third party service unlock, then the hash check for that partition is incorrect and that's why updates fail.
I had a third party unlock it. Actually, it was the guy that people on this forum have talked about.
Will this work on Verizon? My tmo z2 was unlocked by TMobile not a third party
No it doesn't work... You can get data but that's it..

Hi- I am wondering about being able to buy a new-in-the-box z2 Force that was originally sold for Sprint, and being able to flash the T-mobile firmware to it for use with them. Is this possible? I have done this for Galaxy S8/S9 phones, but there is a deal right now where I can get this phone with 2 of the mods for dirt cheap, but it won't really matter if I can't do the conversion. Any advice?
