Unlocked LG G6 US997 Won't Activate on Verizon, Advice Needed

I brought an unlocked LG G6 to Verizon store today to get it activated and they were unable to do this. It appears I have 3 options:
1. Return device to bhphotovideo.com. Not sure what their return policy is.
2. Switch from Verizon to T-Mobile. Live in Silicon Valley close to San Jose, California. Their network is probably fine here.
3. Get an imei from an Android device with nano sim. The Verizon tech person said if I had a friend or family member with this they could get the unlocked G6 working on Verizon. Trouble is that I do not know anyone with an Android phone with nano sim. My old G4 used micro sim. The friends and family members have either iPhones or older Androids with micro sim.
So I could really use some advice here.
And in addition let this be a warning to anyone trying to get unlocked devices working on Verizon. I had read elsewhere that Verizon was now more friendly towards unlocked devices, but this was clearly not the case in my experience. Perhaps this is one reason Verizon is starting to lose customers for the first time in its history.

Cut your old micro sim to nano size put it in the G6 and fire it up. Then your new G6 will work and be in the Verizon data base.
Than sometime go in to Verizon and get a new nano sim. I have been down this road with unlocked phones and its not LG it is Verizon.
If you want to use the old G4 again you need a nano to micro adaptor.
I am using the US997 G6 from BH right now but my old phone used the nano sim so I just had to swap it out. Works perfect so long as you start with a Verizon sim that is already activated.

Earlier this week I activated a new SIM/device with my ancient Galaxy S3 IMEI and verizon sent me a 3-in-1 card that I punched down to the nano size cutout. Which allowed me to put my US997 on the network.

By the way, can you share if VoLTE, WiFi Calling or Video Calling work?

I would like to know the same thing! Thanks

I got this phone all I did was take my sim out of my iphone put it in the g6 and boom it works. Verizon has no idea I have this phone. Lol

Update: got the LG G6 working on Verizon after all. We had to make sure the LG G4 is powered down in order for the activation to complete since the G6 was replacing the G4 on Verizon. And boy do I feel like an idiot for not knowing that. Surprising most of the Verizon staff did not suggest to do this.

I received mine and activated it yesterday. VoLTE works perfectly. No Video/WiFi Calling though. I love this phone! No bloatware!

Are there any other differences between the US997 model and the Verizon VS988, other than lacking wifi calling? (I don't know anyone who actually uses verizon video calling, iphone people use facetime, and as android user I'd always just use duo, hangouts or skype)
How do you tst if VoLTE is working?

I'm also curious about this process. I've done a lot of searching, but haven't been able to find a direct answer yet.
I'm considering buying a Sprint G6, then unlocking it to use it on Verizon. Is this even possible? Obviously, they're both CDMA. And appear to have the bands necessary for Verizon. But I've had trouble in the past with unlocking Sprint devices to work on Verizon.
Any insight is greatly appreciated.

VoLTE worked out the box for me on Verizon. I just inserted my SIM and checked, and it was enabled. WiFi calling does not work on most unlocked phones, and the US997 unlocked edition is no different here. Video calling through the carrier does not work either.

That's great news that you got most of the functionality working, OP. Do you happen to know if the phone was factory unlocked? Or was it tied to a carrier, then unlocked afterward? Again, thanks for any additional info!

Unlikely to work. Stick with the unlocked version, model us997. Keep in mind Verizon sometimes blocks phones from their network that have the necessary hardware, like the ZTE Axon 7.

That's wrong. Im using Axon 7 on Verizon right now. No issues at all.
I really like the G6, not sure if i should get it. I have the Axon 7 as i stated above.

If you want OOB compatibility, the device must be certified through Verizon's Open Development process. See below.

OOB???
Axon 7 is just like Moto X Pure or this us997. They are unlocked with Verizon's bands. Stick an activated sim in them and they will work.

This is old. And only one build. I went through that. They fixed it right away. I had the phone since launch. MM was great out of the box, 7.0 had a hiccup with service, GSM sim after the update fixed it on 1st boot, then you could put your​ CDMA sim back in.
If you buy the device now, the 7.1.1 build will work out of the box.

If you look through the zte forums people have had a lot of problems getting the Axon 7 to work with Verizon. Anyway, I am glad to hear you got it working all right. I like the Axon 7 a lot but was not willing to go through the extra effort that others reported to get it working. And some people could not get it working at all, not a risk I was willing to take. I blame Verizon, I do not think they are supportive of unlocked phones.

Possible to use a Sprint HTC 10 on Verizon with unlimited data & hotspot?

Hi all,
I didn't see anything from reading through the forum on using a Sprint HTC 10 on Verizon. It sounds like there's been success with Tmobile and AT&T.
So far, this is what I've found:
-Sprint HTC 10 should have all the LTE bands necessary for Verizon
-Sprint HTC 10 needs to be sim unlocked before anything can be done
-S-Off + root are required for any potential workaround for Verizon, as the appropriate radio needs to be flashed
How far off base am I? I am intrigued because I am on Verizon and I'd like to take advantage of the sprint HTC 10 sale that's supposedly going on right now. Thanks in advance!

I have the same question. I'm trying to jump on that but for T-Mobile. I'm just worried I won't be able to get the device unlocked.

Historically, Verizon and Sprint don't activate each others' phones. They're the two big CDMA carriers that don't use SIM cards, but activate by ESN directly. But there are always those who get lucky.

? anythin

I've been working on that recently. I actually want to be able to switch between Sprint and Verizon.
Sprint has to activate both the phone and the SIM. Verizon has moved to just using SIM cards. I've been able to move a Verizon SIM between devices and have everything work, even on devices that aren't official Verizon devices and even some that only support part of the bands Verizon uses and work on the ones they support.
With the HTC 10, I've been able to get S-OFF and unlock the phone myself since Sprint wouldn't do it. When I put in my Verizon SIM, it recognizes it but for whatever reason is unable to connect to anything but 1X Roaming (probably on Sprint but it won't say). Poking around in CDMAtool hasn't helped much.
I'll update this if I ever figure it out.

Any updates? I'm curious myself. I have the Sprint HTC 10 and am working on finding an MVNO that I like, some of the Verizon ones are tempting.

By perfectly do you mean volte and Wi-Fi calling are working for you? If so please point to the guide you used. I can't find where anyone using a sprint 10 has gotten those things on T-Mobile.
I would be surprised if a sprint 10 used on Verizon would have that work too but haven't seen any mention of it.

I unlocked the bootloader and installed ViperRom, picking the US Unlocked version as my device. I have working VoLTE, but not wifi calling. (Note, this is on Mint Sim, which uses the T-Mobile network)

yeah it would be great if someone could give a for sure answer to this. I've found a lot of post giving conflicting information all over xda and r/htc10 about this. I would love to buy a used sprint htc 10 (seems to be the cheapest version by far) and use it on a verizon mvno, but until I know for sure it works I' not going to do it.

Google Fi Carrier Switching?

I'm curious, I'm VERY new to the android world (My iPhone XS Max is still my primary)
I started with Androids about a year ago out of both boredom and a desire to learn.
So, I picked up a Pixel 2, then an LG V30, then S8, then S9, until I found the OnePlus 6. I was instantly hooked on the OnePlus 6, only replacing it with the 6T for the fingerprint reader in the screen. (I still have the 6 and 6T, all others were sold)
Anyway - Google Fi is intriguing to me, as I end up in areas were T-Mobile simply doesn't work. I would like the carrier switching, but I don't have a desire to switch back to a more expensive Pixel 3 XL, that really ONLY offers me the advantage of the carrier switching. Overall, I found the OnePlus 6/6T running Pie to be the cleanest experience.
So, my question - Does anyone feel that someone may be able to get the OnePlus phones to do the carrier switching? Or is this actually a hardware feature? I know nothing about how Fi works, so please excuse my ignorance.
Thank you in advance for any productive responses.

Alternatively, maybe I should just sell the 6 and 6T and pickup with 3XL?

Yes, I understand that. But the question was "Does anyone feel that someone may be able to get the OnePlus phones to do the carrier switching? Or is this actually a hardware feature?"
In other words, if the switching software based that may be able to be patched into the 6/6T, or is it a modem hardware feature exclusive to the official Fi devices?

I was hopping this would be fully functional as Fi announced support for non Fi devices, but apparently network swapping is not going to work or work so well. See the write up for the explanation.
https://www.xda-developers.com/project-fi-samsung-oneplus-lg-moto-iphones/

looks to me like the one plus 6 is on there, so, the T might work as well.
contact google directly, and ask them, thats the best way to find out

Ugh, is no one actually reading the question?
I'm not asking if the phone will work with Fi, I'm asking if the carrier switching is does in hardware or software, and if it is software do the devs here feel that they may be able to port the carrier switching to the other supported phones?

ok, now I understand..
asking questions here makes people assume you are discussing the 6T, NOT project fi/android in general..
good luck

Everything I read is that you would only be using T-Mobile. But since the 6t is dual SIM you can have dual service. I plan on getting a one plus 6t and using fi(TMO) for phone calls and texting and Unreal mobile (ATT) for Data. I am not sure if you can use VZW or Sprint for the second SIM but T-Mobile and AT&T is better in most cases than TMO and Sprint (no US Cellular in my area)

Alternatively you can get a pixel 2 or 3 and project fi esim and an alternate SIM. Although it's only one SIM at a time. That way though you do get essentially 3 carriers to choose from for service

So I found if I could dial a code in my dialer for fi, with the Google Fi app installed and activated, and get "cannot switch carrier", all I had to do was clear data on my app and the dialer switch would work

It's on their site. When you choose the 6t it shows what's supported and what's not. See attached image

To answer your question, yes it appears to be a hardware problem. It is either that we don't have the cdma radios needed for sprint or el goog is playing favorites and only wants certain hardware to work for carrier switching between tmobile and sprint. I am not familiar with the us cellular required radios but it is likely the same el goog restriction in this case as well. My vote is that el goog is trying to get people to buy the officially supported devices for full functionality, they are becoming more and more just like all other carriers now, huh?
Either way I think I am switching back to fi now that the 6t is at least officially compatible for use on tmobile and I am almost certain that wifi calling will work where service is poor. I am on tmobile now and wifi calling works just fine, I made a 30 minute wifi call last night and worked perfectly.

So it's a software problem. Google will not release the software as part of an update included with every android release or they won't work with the manufacturer to update the partition responsible

OnePlus 6T has full support for T-Mobile, AT&T, Verizon, and US Cellular. For Verizon and US Cellular, it also supports every CDMA Band.
For Sprint, it has every LTE Band and is missing one CDMA Band. Sprint doesn't allow unapproved devices on their network, and activation is tied to the device MEID unlike Verizon. There's no hardware reason why Fi can't allow at least LTE on both T-Mobile and Sprint. Perhaps the issue is that Sprint restricts them in some manner from using Fi on devices not in Sprint's database. Also Band 71 (T-Mobile) oddly doesn't work on Google Fi, so maybe it would lend credence to there being weird LTE Band restrictions for Fi's carrier agreements.

Well I am going back to tmobile, fi doesn't allow wifi calling and tmobile does so for me it is a no brainer. I still think that there is more going on here than just hardware issues but that's just my opinion. I mean, why is wifi calling not allowed on fi(tmobile) but it is on tmobile?

Not sure if you already switched back or if you are open to trying another service again, but i have been using Mint Mobile for a while now and love it. My monthly payment comes out to $24/Month with 5GB of data and an additional $10/1GB or $20/3GB.

Maybe https://play.google.com/store/apps/details?id=com.cheekydevs.fiswitch can help for OP users?

Awesome dude! It is definitely worth it considering you save at least $40 from any other major carrier. Only thing it doesn't have is the visual voicemail but i never use it anyway so it doesnt bother me.
Hope it is as good for you as it has been for me.

Visual voicemail is working for me with pixel experience ROM on project fi which shouldn't work on OnePlus 6T if I remember correctly.
You try that ROM yet with mint mobile?

Let's take it from the top

Hey guys, long time Samsung user. Finally making the switch to Oneplus 6t. It's on the way. I ordered it from the Oneplus site. Supposed to arrive in 2 days.
My 6t will be on the Verizon network. I understand that I will need to call Verizon and tell them it is a CDMA - less device. You can't access your Verizon account online and do it yourself?
After I get Verizon to recognize it as LTE, here is what I am looking for in my 6t.
I want to root it and install a custom rom. I am not a fan of google so I am looking to use nanodroid. I read in another thread that people have experienced issues when trying to use lineage and nanodroid (Microg) while on Verizon with 6t.
I have also read that Omni rom plays well with nanodroid. So if I want a custom rom without bloat and without google, is Omni the way to go?
If not Omni, I would like recommendations. Thank you

Hello, fellow Verizon user here. If you activate the SIM using the IMEI of the 6t you shouldn't have to call them. You only have to call them if you are transferring a SIM card. I've never had an issue with Verizon on custom ROMs except that the mobile data indicator is broken, and that breaks some apps (Google Pay). ROMs that I've tried and had no issues with are Havoc OS and Omni. Whichever ROM you choose if your choice.

My current phone (Samsung Galaxy Note 8) still has 2 months before it is eligible for upgrade. After those 2 months I can call Verizon and ask them for the unlock code for my current Sim. Is that correct?
What you were saying about the 6t imei, if I do not want to wait 2 months and use the Sim card from my note 8, I can just get the imei number from my 6t and activate it on Verizon?
I've never activated like that. Can you give me a brief description of how to do that? Thank you
Oh nevermind, I found where the IMEI number is for 6T and went to my verizon account and picked BYOD. Looks like it will work that way. Just dont know yet if I will be able to use my current sim card or if I need to purchase a new one.

Ok thank you.

Another question. How many 6t users on Verizon, are still having text issues. Especially MMS. I noticed several people in older threads who were having issues. Some so bad that they were considering moving away from 6t.

suddenly can't make or receive calls moto g5 plus

I do have full data = text, downloads, etc but no calls. All incoming are direct to VM. Any outgoing attempts fail immediately.
It's rooted and I have full ADB access. I replaced the ROM yesterday with 11 google pixle (something like that - I'm not at home where the files are). It worked for a while then stopped again. Dead as far as calls go. The original ROM is voLTE enabled without an option to toggle that. The newer ROM has voLTE and is toggled on. Of course I tried toggling voLTE, airplane mode, toggled cell-data, power cycle on off etc. Nothing gets it going. I'm on ATT. They recently did a G5 update on 2/22/22 and calls worked until yesterday (3/8) . ATT tried sending signals and a few times i was able to make (1).. yes - ONE call - then it fails afterwords - weird isn't it?
I'm hoping you guys might know a pretty solid ROM i can install (old or new - whatever works best with this phone) nothing fancy - just operational is fine. Or if you think I have a hardware issue and should add a hook to the phone for a lure I'd rather not if I can get it going again - I believe it should work but maybe something with the ATT G5 is adding to my troubles - any suggestions please - I'm at a loss
Thanks in advance - Jim

Hi Jim, I just joined xda in hopes of finding out if a new rom will solve this G5plus moto problem. From what I gather, the standard installed rom does not support Volte and when the wireless services dropped 3g, it somehow dinked with volte/lte (that level no longer supported). I am in the same situation with my g5+ - text but no voice. I use H2o wireless service. From my upfront investigation, volte is a software solution, and no extra chips are required, but I may be wrong, I am just getting started with this. It seems odd to me that I can take out my sim and put it in an older J3 Samsung, and calls go through fine and I can see Volte settings listed. What was moto thinking on the G5+, makes no sense. Sooooo, if anyone has any input to this problem or know if a rom might solve it, chime in please, the phone is still okay for low level use.
Thank you,
Barry

When I re-flash the ROM I can make one call again then nothing. This tells me it's not hardware but software. So I decided to visit T-Mobile to see how it works on their G5 voLTE network and it does quite perfectly. It's not the phone, never was!
So here's what I'm finding out so far. ATT has created a 'white list' of phones they are allowing on their new roll out of the 5G voLTE system. The Moto G5 Plus is not on that list. According to an ATT blog site they are blocking IMEI's that aren't on that list from making calls. The arguments on that site include comments that regardless of your phones proven and manufactured ability to process voLTE calls they aren't going to allow them. It's BS. According to this site it was up to the manufactures to submit phones for approval. Obviously they aren't going to submit discontinued phones, so...
I'm with ConsumerCellular which is ATT essentially. Finally after 4 days CC says they have a new SIM that has been fixing this issue and shipped one out for me today. I'll get it next week. I'll update here accordingly. They call it a "3-In-1 Smart Sim - A" I'll find out just how smart it is ;-)

Yea, I found the att whitelist and all the controversy. Let us know what happens when you get it, maybe H2o can send me one also. Possibly too much programming to allow the G5+ in the mix, could get interesting as time passes.
https://www.att.com/es-us/idpassets/images/support/pdf/Service-Capabilities-Unlocked-Devices-ATT-Network.pdf

I'm leaving ATT. Consumer Cellular sent me the newer SIM. They couldn't get it to work either. The T-Mobile sim worked perfectly in my existing phone - voLTE, 4G (not a 5G phone) and wifi calling. In the mean time to make matters worse, I received a Moto One 5G Ace (brand new phone) direct from Motorola claiming to have whatever upgrade was necessary. Doesn't work either on ATT. I called Moto to question why menu options are missing. Without hesitation she said it's not a 5g phone for ATT and offered a refund. Really.. ok, who am I to argue - I'm taking the refund. I'm moving my existing phone to T-Mobile and not fighting with the big bad ATT bully for doing this.
IMHO ATT doesn't deserve to keep any customer they've done this too. Laziest roll-out in history
So don't fight it, just leave. Any company that blocks IMEI's and dumps customers who own known good 4G voLTE phones is saying loud and clear - LEAVE US.
so that's how I'm fixing the ATT issue. Just the way they way want it.

Yeah, I'll echo this. My G5Plus is on StraightTalk (AT&T MVNO), and voice just stopped working days ago. The SIM works for voice in my Pixel 3a though so getting a new SIM would do nothing. Pretty bogus that VoLTE works with some carriers and/or variants of this phone, just not AT&T apparently.

According to the ATT blog they're blocking the IMEI's of any phone not on their white list. I'm confident it would work they just don't want to be bothered with testing it since the manufacture didn't send them a phone. It's a discontinued phone so why would Motorola do that. However being discontinued only means they made a production run of so many phones and have sold out. On to better iterations .. I get that. They still work and will for years to come on 4G and voLTE. It's an ATT thing. They work great on T-Mobile (not a fan but..)

I'm leaving ATT. Consumer Cellular sent me the newer SIM. They couldn't get it to work either. The T-Mobile sim worked perfectly in my existing phone - voLTE, 4G (not a 5G phone) and wifi calling. In the mean time to make matters worse, I received a Moto One 5G Ace (brand new phone) direct from Motorola claiming to have whatever upgrade was necessary. Doesn't work either on ATT. I called Moto to question why menu options are missing. Without hesitation she said it's not a 5g phone for ATT and offered a refund. Really.. ok, who am I to argue - I'm taking the refund. I'm moving my existing phone to T-Mobile and not fighting with the big bad ATT bully for doing this.
IMHO ATT doesn't deserve to keep any customer they've done this too. Laziest roll-out in history
So don't fight it, just leave. Any company that blocks IMEI's and dumps customers who own known good 4G voLTE phones is saying loud and clear - LEAVE US.
so that's how I'm fixing the ATT issue. Just the way they way want it.

I left, the ole Moto G5+ up and running with voice on T-Mobile, the 15 buck plan unlimited talk/text 3GB data. Cut my bill in half, will see how it goes and for how long.

Thanks for all of your replies. My wife's Moto 5 Plus suddenly stopped making or receiving calls last week and I was pulling my hair out trying to figure out why. She has a pay-by-the-minute plan through TracFone, which uses AT&T's network (among others). Guess she'll have to look for a different carrier now. Judging from others' replies here, T-Mobile seems to be the way to go.
Just got a notice from StraightTalk that my iPhone 5s will no longer work soon, for similar reasons. I probably should upgrade, as half of my apps no longer work on its old iOS... but I really don't want to give up my headphone jack.

According to the ATT blog they're blocking the IMEI's of any phone not on their white list. I'm confident it would work they just don't want to be bothered with testing it since the manufacture didn't send them a phone. It's a discontinued phone so why would Motorola do that. However being discontinued only means they made a production run of so many phones and have sold out. On to better iterations .. I get that. They still work and will for years to come on 4G and voLTE. It's an ATT thing. They work great on T-Mobile (not a fan but..)

jgdorado,
Thank You So Much! We went from Verizon, to AT&T to Pure Talk -only to find out what you just told us about being black listed by AT&T. We just switched today to T-Mobile and ey wallah -both Moto G5 Plus, XT1687 work on Android 8.1 perfectly now. WFI Calling, & voLTE working. You ROCK! God Bless y'all, especially XDA Dev's!
