AT&T Specific Stock ROM - Google Pixel 4 Questions & Answers

I noticed yesterday when I went to download the March OTA image that there was one specific for AT&T. Anyone know why the Pixel 4 has a specific image for AT&T?

No. But it was pulled because it failed certification and was not passing Safety Net. So, right now, there's only the other build available.

Thanks for that. I just rant into an article on Android Police that it's coming back soon. I'm still curious as to how this differs from the standard ROM. My curiosity is driven by the fact that I'm on AT&T and haven't been able to enable Wifi Calling or Number Sync. I was told by the AT&T reps that it's because the phone doesn't support VoLTE, which is BS. While AT&T generally blocks non-AT&T purchased phones (unlocked or not), the Pixel line is exempt and supports all of their services. I had no issues with the Pixel 3.

That exemption was for the Pixel 2 and 3, which AT&T didn't sell. Now that they sell the 4/XL, they are uncertifying unlocked Pixel 4s. Only AT&T bought models are authorized by their servers to have VoLTE and WiFi Calling. Without VoLTE, you won't have access to WiFi Calling.

I didn't even know AT&T sold the Pixel 4. One of the primary reasons I bought another Pixel was because of AT&T support of unlocked Pixels. I guess not anymore.

I had an at&t pixel 4 from November. Had to do warranty and received a Google pixel 4 in return. I have wifi calling.
Btw, yes I unlocked the bootloader immediately lol

It's a different case because you already had a registered AT&T Pixel 4 IMEI before you switched to an unlocked model. AT&Ts servers will still read your phone as an authorized model. Try getting an unlocked Pixel 4a or 5 (or whatever model comes next, for example) instead of a branded AT&T model and you will have the same issue as I.

I had the 3a, 2, 1 and nexus devices before. The 4 was my first "at&t" phone.

So, i know it is a pain and it's because they want you to buy their "branded" crap. However, for a workaround, find an at & t branded iphone that has volte vowifi capability and put your sim in there. Then call AT & T or use their live chat support. Tell them you are trying to activate your sim with volte and vowifi for your sim. They will activate it for the that sim card. Once you verified the iphone shows volte and vowifi take your sim out and put it in android phone of choice. I found this out since my sister (sadly) is an apple user and i use all android phones. Once the sim is unlocked for volte and vowifi i haven't had any issues on my pixel or my op 6 or op 7 pro.
Good luck. Might be a pain if you don't have access to an i phone, but swappa is fairly reasonable for a 7 that you can use and then sell to a friend or something . Good luck.

[All CDMA Carriers] Before Buying a Nexus 6, Consider Where You Buy It

Just wanted to post a public service here for y'all.
If you're buying a Nexus 6 and plan to activate it on Verizon, Sprint, or US Cellular, you should either buy it from your carrier of choice or from Google Play. Unless Google pulled off a miracle (unlikely), all the CDMA carriers will only have IMEI numbers whitelisted for devices sold from Google Play and devices sold by that carrier.
In other words, if you're planning to skip Google Play and instead buy one from T-Mobile at full price, then walk over to a Verizon store and activate it, it's not going to happen.
Further, if you're buying a Nexus 6 and expect to be able to activate it on any of the 5 supported carriers at the drop of a hat, buy it from Google Play and don't even consider buying it from a carrier.
If you want a more in-depth explanation, I made a video on this.
https://www.youtube.com/watch?v=9cCT_ifWGLs
UPDATE
Now that people are getting their Nexus 6s, we've got some more concrete information. Keep in mind that every Nexus 6 sold in the US supports CDMA. The problem is, unless you buy it from specific places, the carriers' systems won't allow activation.
VERIZON:
Verizon is not officially allowing any Nexus 6 on its network yet, however, that's only through official channels.
If you have an already-active line, you can take your SIM card (cut it down to nano size if necessary), put it into any Nexus 6 (no matter where you bought it), and you're good to go. If you need a new line of service, you'll have to activate using an IMEI number of a display device that takes a nano SIM (I'd recommend an HTC One M8 or a DROID Turbo), then once you get your SIM card, put it in your Nexus 6 and you'll be golden. And no, this is not stealing IMEI numbers. The minute that SIM goes into your Nexus 6, the display model's IMEI number is freed up. There's nothing morally questionable about this method at all.
SPRINT:
Sprint will currently allow devices sold from Google Play, Motorola, Sprint, and AT&T. We aren't sure about devices purchased from T-Mobile, or US Cellular. Since Sprint whitelists devices at network level, your MEID must be in the system in order for your device to actually handshake with the network. The Verizon trick of using an already-activated SIM card won't work for Sprint.
US CELLULAR:
USCC will activate devices that they sell, as well as ones purchased from Google Play. I attempted to activate my AT&T-purchased phone on USCC and the MEID (IMEI minus the last digit) was not in their system, therefore it could not be activated. Since USCC, like Sprint, whitelists devices at a network level, the Verizon trick of using an already-activated SIM card will not work. There is presently no word on whether or not USCC will activate phones purchased from Motorola, but I'd bet the answer is no, at least for now.
Great explanation. Thanks. I'll definitely be buying mine from the Play Store for use on Verizon.
So your implying that one cannot buy a T-Mobile Nexus and then use it on ATT? I would have to say BS in this particular scenario IMO.

Given that they don't know where you bought the device..... and the fact that you can buy a device from Google, that's designed and advertised to work on all carriers..... and the fact that there is only one sku for all NA variants.... and they aren't making you choose a carrier when you order one..... This myth is busted. If I buy one from TMobile and take it to Verizon I can simply say I bought it from Google..... In which case they have to honor it because Google is selling it as compatible with all carriers.... Do you see? There isn't a "verizon" N6. If there was you would have to provide your carrier of choice at checkout. Otherwise the idea that they are comparing IMEIs is bunk.
lets say this is all true and u cant do that......what if i get from motorola site?

seems it was the case for the N5. https://community.sprint.com/baw/thread/150262
So it is very likely the same case would happen to the N6.
I planned on buying from the play store anyways.
Thanks for confirming my suspicions.
Honestly, anything at this point is purely speculation. I don't think you can confidently say that buying from t-mobile means your phone won't work on sprint or vzw...
I just hope vzw hasn't done something really dumb and only recognize IMEI numbers sold through THEM (not even google).

Quite the contrary, I understand CDMA well enough to not consider it if it was the last technology left still in use. (Ex Red subscriber). I totally agree that CDMA providers will need to whitelist the imei#. But by the OP's quote that I highlighted he said "any of the 5 supported carriers". Last I checked, 2 of the 5 supported carriers were GSM. (AT&T and T-Mobile in case you didn't know). I specifically was saying that I call BS that a T-Mobile phone would have any issues what-so-ever starting up and working on a AT&T network. So either you'll are misunderstanding me or I am more tired than I thought and have misread the OP in which case my bad...

I'm wondering if the Play Store units are only compatible with TMo and ATT. Look at the way the carriers are listed on that image. TMo and ATT are above the line with the Play Store link. The CDMA carriers are below the line on their own. That can't be an accident.
Alright guys, time out.
Every Nexus 6 sold in the US, no matter where it's purchased from, will technically work on all 5 carriers. The issue is, the CDMA carriers won't have IMEI numbers white listed for stock sold from other carriers. Based on the IMEI number of your phone, I can tell what color it is, how much storage it has, and where it was sold.
You can activate any Nexus 6 purchased anywhere on AT&T or T-Mobile because they're GSM and don't care where it's from.
You cannot buy a device from anywhere and activate it on Verizon, Sprint, or US Cellular, though. You can lie and tell then you bought it from Play but it won't matter. If you purchased your phone anywhere other than Play or the CDMA carrier you're trying to activate with, they won't have your phone's IMEI in their database, thus no activation.
As for devices purchased from Motorola, I'm not going to speculate because I have no history to go on, but I would imagine that those would be OK as well.
T-Mobile and AT&T will take any Nexus 6 sold anywhere.
Verizon will take a Nexus 6 sold from Play or Verizon.
Sprint will take a Nexus 6 sold from Play or Sprint.
US Cellular will take a Nexus 6 sold from Play or US Cellular.
It doesn't matter that your Nexus 6 that you bought at T-Mobile works fine on al the CDMA carriers (and it will). The CDMA carriers will not activate it purely because the phone won't have a whitelisted IMEI number due to the fact that it wasn't purchased from that carrier or Play. It's no more or less complicated than that.

That sounds logical, except its not how the cdma carriers work. The iphone 4s (and now the 6 and 6 plus in the US, though sprint has a different model, but verizon uses the same model as att/tmobile) was the same model for cdma and gsm, but it wouldn't work on cdma networks unless originally purchased from a cdma network. Basically they whitelisted imei numbers to only activate iphones that were orignally purchased on cdma networks even though the model was capable of both gsm/cdma.

I think what a lot of people don't understand is that you can tell by a phones IMEI number where it was purchased, it's color, the storage, and model number. So you're exactly right. The CDMA carriers only whitelist the devices that they sell, and they enforce that via the IMEI number.

The only time I have ever heard of Verizon allowing a non-Verizon or non-Play Store sold device on their network is by someone having an insider connection and white-listing it. I think it's pretty safe to say that if you buy a device from T-mobile, it will not work on Verizon, unless Verizon changes the policy that is has had in place for years.

An N6 bought from T-Mobile will work on AT&T and vice-versa. The OP was specifically referring to CDMA carriers.

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.

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.

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.

Samsung S8 - Unlocked Phone - No Wifi Calling? What Else Am I Missing

I bought an unlocked S8 at Best Buy because it was a good deal.
However, I'm noticing AT&T is restricting Wifi calling. There isn't even an option to turn in on.
Are they preventing this? If so, can I get it turned on by them ? I'm assuming there is a ROM I could flash to get it, but I would hate nothing during flashing bricking my phone.
Any other features I'm missing? Since I have really bad coverage at my desk at work, WIFI calling is important to me. I'm considering returning the phone and going to ATT brand, but there is a $35.00 restocking fee. I feel Best Buy should have told me the downsides of an unlocked.
I didn't get any restocking fee when I returned my ATT S8. Got a full refund, no questions asked. Besides if you're just swapping out to another carrier one, I'm sure they will waive it. I have MintSim (Tmo) and WiFi calling can be enabled and works fine for me on the unlocked firmware on my Vzw S8.
AFAIK, AT&T does not allow wifi calling for non-branded phones.
Can anyone explain to my why this would be? Is there any technical reason that they cannot do this on an non branded phone or are they being difficult?
I know it could be that they are strong armming me into another 2 year agreement, but if I can't use Wifi Calling, I cannot use their service due to poor reception at work. I think it would be in their best interest to let me use this feature.
Everyone I talked to on phone and in store basically act like it should be fine.

WiFi is not possible on AT&T network with the Unlocked version of S8 phones
This may help others who are considering the Unlocked S8.
Note: As of today, no options available from either AT&T or Samsung to enable WiFi calling.
After multiple trips to AT&T, BestBuy Samsung, chat sessions with Samsung support and now calling Samsung Premium Care, I finally confirmed that the Unlocked S8 model does not have any possible software upgrade to enable WiFi calling. Why did so many not know?
Samsung:
Please revise your website to clearly state the limitation, (WiFi is not possible on AT&T network ), with the Unlocked version of your S8 phones.
What's Next?
I was told that there is nothing that Samsung can do for me but Return the phone for Refund.
Now returning this phone requires me to again pay additional cost for replacing/activating another SIM for my old phone to use during the time I process an order for my next phone. Samsung cost me hours of my time and wasted my money.

wifi calling is a feature enabled by a carrier, not the phone brand. if you want wifi-calling, flash the relevant firmware for your carrier just like i did for VZW to get wifi-calling to work. and btw, this information was widely known by doing some research previous to purchase. i had no problem finding this out but ordered anyway with the intent to flash the firmware.

and wifi calling won't work. just gives me this message:
"Oops!
We can't turn on Wi-Fi Calling for your account. Think this message is a mistake? Ask the person who can make account changes to call us..."
After numerous calls to Samsung and AT&T you absolutely cannot enable wifi calling on the unlocked phone. Only phones purchased as AT&T branded are allowed the full feature set.
If in fact you DID buy an AT&T S8, you can unlock it and keep said features, but not in reverse of that. Which blows.

That really makes no sense.... (Not that you're lying) but there's specific firmwares for the unlocked S8's depending on carrier. the G950U1 has different CSC's depending on what carrier it's used for. Why do that if it doesn't enable that carriers features?!

flashing other carriers might work (like Tmobile), but not with ATT as they are using based on the IMEI registered with ATT brand.. so flashing any CSC won't enable it as long as you spoke to their customer care and provide your No and other ATT phone to activate Wifi calling on your number.. this is not 100% working method.. search through teh CSC selection forum there people posted a workaround.

This may help others who are considering the Unlocked S8.
Note: As of today, no options available from either AT&T or Samsung to enable WiFi calling.
After multiple trips to AT&T, BestBuy Samsung, chat sessions with Samsung support and now calling Samsung Premium Care, I finally confirmed that the Unlocked S8 model does not have any possible software upgrade to enable WiFi calling. Why did so many not know?
Samsung:
Please revise your website to clearly state the limitation, (WiFi is not possible on AT&T network ), with the Unlocked version of your S8 phones.
What's Next?
I was told that there is nothing that Samsung can do for me but Return the phone for Refund.
Now returning this phone requires me to again pay additional cost for replacing/activating another SIM for my old phone to use during the time I process an order for my next phone. Samsung cost me hours of my time and wasted my money.

Time I understand. You will never get that back. The SIM card issue I don't understand. Didn't you keep the old sim card from your old phone. Yes, AT&T will have to reactivate it, but they should do that for free. The only time I've had to pay is when I needed to get a new physical SIM card because the size was wrong for the phone I wanted to use. If you kept the old SIM card, you can simply reactivate it and stick it in your old phone again.

it's all tied to your IMEI, and that can't be changed. the VoLTE and Wifi Calling are non-existent unless you bought an ATT branded phone.
Guys ... I'm still looking for other options BUT this will work ....
If you have a business account you can just go in to the account and change your billing acct IMEI for your unlocked phone to an IMEI of an AT&T S8 (get one from a friend, go to the store and check out the displays, etc)
If you don't have a business acct call support , eventually you can get a person that knows what to do and they can plug in a working IMEI
This works ... works on my S7 Edge as well
Flashed unlocked phone with ATT FW. Then changed my account's imei with the imei from an ATT branded phone and that got me advanced calling options. Wifi calling will worked for about 10 seconds until ATT reads the phone's actual imei and then they turn off wifi calling. Volte will continue to work.
AT&T OTA Update Coming
All, I have just confirmed with AT&T they have made the request for an OTA update to enable WiFi Calling in the Settings Menu from Samsung. The time frame I was given as of yesterday 10/2/2017 was 14 days. So by 10/16/2017 S8 & S8+ phones should receive an OTA update that enables WiFi Calling feature.

OnePlus 6T Dual Sim Question

I am considering a OnePlus 6T so I can consolidate my two phones to one. I currently have Verizon and GoogleFi.
Will I be able to receive calls and text simultaneously on both numbers?

Yes.
Only one number controls data.
I use Verizon and T-Mobile.
You need to chat/call with Verizon and have CDMA_Less added as a feature to the line since there is no CDMA on the 6T.
It works great for me.
On the international version, you can switch data back and forth at will (there is a tile to do that quickly) but if you prefer, you can even enable dual 4G networks for both sim cards!
Cheers!

my understanding is that your Google fi Sim will default to T-Mobile only if you use it in a OnePlus 6t. you will lose the network switching benefit to Sprint and US Cellular that you get on a Google fi approved phone. So, effectively you'll have T-Mobile service on one sim and Verizon on the other.
I have heard that if you use a Google pixel with Google fi and have it set up as an esim, you can use a secondary Verizon sim in the open SIM tray. That would mean you'd have the full benefits of Google fi service as well as Verizon. As noted below, only one sim at a time can control data. Long and short, you need a pixel phone to do this because the OnePlus 6t cannot fully utilize Google fi service.
Take everything I said above with a grain of salt because I do not have a pixel phone. I am however using a OnePlus 6t with T-Mobile and XFinity mobile. The problem with my setup is that Xfinity mobile only gives me calling. I cannot receive text or use mobile data with my Xfinity Sim. This may change later once Xfinity approves "bring your own Android phone" to the service.

If this works exactly as you said it would be perfect because I don't care if my Fi sim ever connects to data, in fact I would like it to never connect since I have unlimited with Verizon and Fi costs me $10 per GB.

Thanks for bringing up that point it is very likely important to someone but for me my current Fi phone is on TMobile 99% of them anyway because sprint has very little coverage in my area. US cellular is non existent for me as well.
I have a Pixel 2 Xl now for Verizon and I thought about getting a Pixel 3 when they came out. I spent about an hour on the phone with Google about this subject and unfortunately according to Google (and a few threads here on XDA) the Pixel will not allow you do have both Esim and Sim active at the same time. So if I have my work number (Verizon) active, my old personal (Fi) will not receive calls or text and vice versa. You have to manually switch the service to use each.

I guess Gixel 3 allows using eSIM and normal SIM simultaneously with Android Q update. Bear in mind there's still a single radio so while call on one SIM is ongoing any calls on other SIM can't be known.
I have fi (tmo) and unreal (att) works perfect. Only thing is messages sometimes will fail to send. Using hangouts does fix it, only problem is that Android messages is a better app in general
works great on Tmo and ATT. using Google Messages, Google Dialer and data works fine. i have rooted converted TMo OP6t with dual sim tray. Tmo VoWifi/VoLTE works, but ATT only support VoLTE on OP6t.

Question while using Google messages. Do both of your phone numbers pop up everytime you try to type a message it's super annoying for me and the only reason I stopped using it..
Used to do that, but it stop doing it and just works. Not sure what i did. I forgot. sorry. Disabled the stock messages app and default to google messages.

I have ATT and picked up a Fi sim over the weekend. Took me a while to get it activated (had to pop it in my OP3T for it to actually work, the dual sim feature didn't play well with activation). ATT is primary and Fi is secondary for everything. I have dual 4g radios enabled but that only enables VOLTE for Fi, but the actual data is used through my primary sim (ATT). SMS messages were not received if hangouts was disabled for SMS and Fi was not set as the primary Sim for SMS. Aka SMS doesn't work unless you make Fi the primary SMS sim or use hangouts for SMS, which is fine but defeats the purpose of using the dual sim features in your default SMS app (tried this with both textra and google messages).
As someone else said already - android Q will bring dual sim dual standby to the pixel line.

Just say no.
If you need dual SIM functionality, just but the international version.
Buying the T-Mobile version mead a pain to get it unlocked before the 40-50 days.
If you flash the International ROM before then you will need to flash back to stock to unlock the SIM.
Buy the right version from day one.

I did not have to wait 40-50 days to get my t-mobile variant unlock. I reached out to tmobile via twitter and paid 2 months of installment ahead of time and received a permanent unlock from tmobile. I currently have a verizon sim(Work) and tmobile sim(personal) in mine with the international rom.

That is hit or miss.
There is no guarantee that you can get an unlock.
So if you buy with the knowledge it may take 40-50 days for an unlock you can't be angry.

VZW bootloader IS unlockable (not grayed out and switchable)

Weird, its grayed out for me
Were you able to root it?
A little off topic, but why do people buy the Verizon version when you can buy the Unlocked version for the same price and 0% interest financed?

Some people don't know, some people have weird trust issues, sometimes the Verizon one is much cheaper.
I wish there were confirmation on this- local Verizon stores have stock while WorstBuy requires shipping or store stock next week.
Nope, picked up a 3a from a Verizon corporate store (asked for clearly white, turns out it slightly purple) and no joy on OEM unlock. Toggle is grayed out and states "Unavailable on carrier-locked devices". Going back tomorrow and hopefully won't get dinged $50 on the return since they gave me the wrong color but I don't think that will play out.

Well the bootloader definitely cannot be unlocked if the carrier has it sim carded locked. Carrier issued phone are generally sim card locked by default and the user has to usually request for the device to be sim card unlocked. I still don't believe the Verizon edition will be bootloader unlockable, but seeing that particular message does not confirm one way or another as it appears on every carrier sim card locked device - even those that can be bootloader unlocked once the phone is sim card unlocked.
I can confirm this true, at least in the bestbuy I bought my pixel 3a.
Like I say bought on bestbuy unlocked, when I get home turn on without a sim card and no WiFi, then turn on developer option and there was the beautiful oem unlock available, immediate I turn on and go to fastboot and do the fastboot flashing oem unlock and successful, now I rooted with magisk and button remapper with the active edge remapped.
P.s it was in the latest firmware
i wonder if the method for the orig pixel would work. would be funny if it did. for those wondering https://forum.xda-developers.com/pixel-xl/how-to/how-to-unlock-bootloader-verizon-pixel-t3796030 i doubt it will, but might be worth trying
So, stupid question, but the Google Store site wasn't completely clear on this...if I buy the unlocked Pixel 3a from Google's site, will it work 100% with Verizon's network? Will it have all of the same LTE bands, for example, or will I see reduced performance compared to the Verizon-locked version? I'm used to the old days where I had to buy one version of a phone for VZW and a different version for AT&T...
Yes, the unlocked 3a works fully on Verizon's LTE bands as well as calling over WiFi and VoLTE. 100% compatible and none of the preinstalled crap.

It's the same only the differences are that one it's unlockable bootloader(Google) and the other not(verizon).
Both have the same bands and processor, etc.
If you want to make this phone more great and you knowledge about flashing and that stuff buy from Google but if you don't care about that buy the one from verizon and I don't sure but on verizon have very good discounts like 100 bucks more cheap with activation.

No, the Google Store version and Verizon version are NOT the same. Almost, but not "just the same with one sim locked". They don't have exactly the same model name and LTE bands.
Verizon Pixel 3a model: G020E
Google Store Pixel 3a model : G020G
The Verizon model miss some LTE bands (14, 29, 30, 71) and miss e-sim support. Maybe Verizon LTE network doesn't use the missing bands and there is no difference with the LTE coverage, but they are not the same.

I know this is almost a 2 year old thread but just bought a used Verizon 3a because my Pixel died. I have to have a Verizon version because those are the only phones that Page Plus will activate. Anyone know which OTA version they were able to unlock on? Have my doubts any of them will actually work but wanted to know before I update too far. Currently on QQ3A.200605.002.
I know I did not get a response before and have upgrade to the latest April 2021 patch with no success at unlocking. Wondering if anyone has tried using a AT&T sim to try and unlock bootloader? Not sure how the phone knows it is a Verizon phone. The OTAs are for all versions. Wonder if there is something in the code that could be tweaked before install.
