UPDATE: Droid Life confirms unlocked Pixel works on Verizon. :good:
I just wanted some clarification on this.
I've been getting some conflicting information around this question, so I wanted to post it here in case anyone knows.
Can the unlocked Pixel purchased from the Google Store be used on Verizon?
I bought the 5X and 6P unlocked from the Google Store and have used them both on Project Fi and Verizon. I just wanted to know if I could do the same with the Pixel.
Thanks and sorry if this has been explained clearly elsewhere.

Yes. It is compatible with CDMA and all of Verizon's LTE bands, and the description in the Google store says it's compatible with all major US carriers. However, you won't be able to use features that require Verizon software like wifi calling and VoLTE. Personally, I don't care about those things. I'm on Verizon and I'm seriously considering buying from the Google store.
You'll need an activated Verizon nano SIM card though.

I'm not sure that's true. For example, my unlocked Nexus 6 purchased from Motorola is able to use VoLTE. I don't have wifi calling, but I don't think Nexus 6 has wifi calling at all for Verizon, as it doesn't show up as a supported device: https://www.verizonwireless.com/smartphones/wificalling/

You might be right about that. We won't know until someone tries it.

Good question. I suspect the answer is you'll be able to use it, the question is just how degraded the experience will be. When the Nexus 6 launched there were several problems with using the unlocked version:
The bring-your-own-device discount did not show up for unlocked Nexus 6, only Verizon-purchased Nexus 6
It was extremely difficult to activate a new SIM on the phone
They did eventually reinstate the discount after many people filed complaints with the FCC.
I didn't follow the 6P/5X launch very closely... how did those work on Verizon? That might give a better clue than the Nexus 6 launch since it's more recent.

If it's like it was on my 6p, then plug in your nano sim and go! I've had zero issues with Big Red over the last year, and Volte is working fine and dandy [emoji106]

To clarify, you got your 6P unlocked from Google/whoever, not Verizon? And Verizon is giving you the $25/month discount (assuming you are not under contract)?

You are correct. Got the phone from Google, plugged in my Verizon sim and it's still working fine. I'm not under contract, I never am, however, not seeing any $25 discount from Big Red. Guess they keep that for themselves [emoji16]

Pardon me, I'm from Canada where we haven't had any CDMA for years. Aren't Sprint and Verizon CDMA whole at&t and T-Mobile are GSM? How would one phone work across all the networks? And, at least last time we had CDMA up here, you didn't use a SIM card with it. Has that changed? Just curious, it doesn't affect me at all.

I wouldn't call paying $300/year extra "fine". You might want to look into it, I believe you have to request the discount. It's been a while since I dealt with this though.

Hey dude... I recently switched over to Verizon, and have had a 6P since launch last year. Was wondering, what exactly is voLTE, is there something special that has to be done to make it work, and do you know IF there is any way to get wifi calling to work? I do tend to need it since at times I don't get good reception...

voLTE is just voice over LTE which you already have which basically means voice and data simultaneously. And no WiFi calling calling available on Verizon. At least not to my knowledge anyway [emoji106]

Just to add...
My son's 6p works great on Verizon. He has VoLTE and get's the non contract discount. Never had a problem with it. I had the original Google Play store Nexus 6 and ran into problems initially. But like someone else stated, everything is fine now. I even bought an unlocked one not too long ago and had no issues with it. I don't think we will have any problems with the Pixels.

I also want to confirm that with the Nexus 5X from Google (rooted and custom ROM) works flawlessly on Verizon and I get the $25/mo access discount on the line. VoLTE works great. I just select the Enhanced 4G LTE Mode under Cellular networks menu on the settings.

VoLTE is Voice over LTE. It means voice calls are transmitted over the new LTE network instead of the legacy CDMA network (or GSM in the case of carriers besides Verizon/Sprint).
It's important because if your phone has only a half-duplex modem, as most recent CDMA phones starting around the time of Droid Turbo and Nexus 6 do, you can't conduct a voice call (circuit switched) and have an LTE data connection (packet switched) at the same time. (Interestingly GSM carriers can do a GSM voice stream and LTE data stream at the same time with a half-duplex modem since there's a standard for doing that, but it's not possible with CDMA and LTE without a more expensive full-duplex modem.)
How can you tell if VoLTE is working for you? Turn off wifi for the purpose of the test, if you're connected to a wifi network (you're testing whether you can do data over the cell network, not wifi, while a call is ongoing). Verify the "LTE" logo shows up next to the cell signal strength indicator. Place a voice call. If the "LTE" logo disappears while the voice call is ongoing, you don't have VoLTE. If it remains, you're good. Most importantly, try using data e.g. web browser over cellular data while on a voice call.
What if the VoLTE test doesn't work? On your My Verizon account, go to My Plan & Services -> Manage Products & Apps , and make sure "HD Voice" (they used to call it Advanced Calling) is enabled. On your Nexus Settings, go to Wireless & Networks -> More -> Cellular Networks, and turn on "Enhanced 4G LTE Mode" if it isn't already. Note that turning on HD Voice on your Verizon account requires you to switch to either Basic or Premium Visual Voicemail -- the old fashioned voice mail doesn't work with it.
What's the difference between VoLTE and HD Voice? VoLTE is about the connection from your phone to the Verizon tower, and it applies no matter whom you are calling; it enables simultaneous voice and data. HD Voice is a high-bandwidth codec for much better sounding voice calls, but the other end has to support it too, so it only works if you have VoLTE (HD Voice over non-LTE is theoretically possible but Verizon doesn't support it) AND if the person you are calling supports HD Voice too (e.g. another recent Nexus or iPhone that's correctly configured). You can tell if HD Voice is working because the "HD" icon will appear in the dialer AFTER THE OTHER PERSON PICKS UP THE CALL, but you won't even need to look for the icon because the call will sound so vastly better that it will be obvious.
What about Wifi calling on Verizon? They actually DO support it, but not on Nexus devices. Here is their FAQ and list of supported devices, which does not include Nexus 6/6P. I have personally seen it working on a Verizon iPhone so I know they have it. And, according to this, the Pixel will support wifi calling on Verizon!

The Pixel, along with many "international" phones, supports both CDMA and GSM networks. And yes, CDMA carriers like Verizon started using SIM cards several years ago. I think it's necessary in order to offer LTE compatibility, but I don't know the details.

LTE is GSM based at it's core, so basically yes LTE is the reason for CDMA carriers adding sim cards.
CDMA will eventually disappear completely as VOLTE replaces 2g and 3g for both voice and data transmission.
Wi-Fi calling is the only question, but even if it requires some proprietary VZW bull, an unlocked bootloader should let us flash their image if it ended up being necessary, but that's a last resort I don't expect to face...
A couple of weeks back, I purchased a factory unlocked S8+ Model #G955U1, Baseband Version G955U1EU1AQE3 (The AT&T Galaxy S8+ has different Model and Build #s), inserted my AT&T SIM card and have been using it since. Then I decided to activate WiFi calling, however, unlike my wife's iPhone 7, my Galaxy does not have the option to enable WiFi calling (this option should be under Settings>Connections). After some research, I found out that this a carrier feature which AT&T must provision. When I asked them to do it, they provisioned it on my wife's iPhone 7 but not on my Galaxy, so I called them again and asked them to provision it on the Galaxy. Although they insist that they did, the feature does not show up on under AT&T Devices (It shows up under the iPhone but not the Galaxy). After spending no less than two hours speaking to three agents, I learned that AT&T does not have in their data base the IMEI number of the Galaxy because it was not purchased through them. So obviously, not having an IMEI number, the WiFi calling feature is not going to be pushed to my Galaxy. Not being able to solve the problem, they escalated it to another level who is supposed to contact me two days from now. A friend purchased his Galaxy S8+ through AT&T and the WiFi calling option is there in Settings>Connection and he is able to toggle it on or off. When I used AT&T's IMEI Verification tool, the result was "Device is compatible but we cannot find matching SIM card".
Any and all input would be appreciated.
Same here. Looks like wifi calling is not a feature that is available on the unlocked version unfortunately. Same with using LTE while on calls and built in visual voicemail :/
You have some advantages going unlocked but you lose some things too.

I am pleasantly surprised and a bit puzzled because when I spoke to T-Mobile Tech yesterday, she could not confirm if WiFi calling will work on unlocked S8+. If I can be assured that it will work, I will switch to T-Mobile.
Please do me a great favor and check if your unlocked S8+ has the same Model and Build Numbers as mine. Here are my numbers:
Model #G955U1
SM-G955UZKAXAA
Baseband Version G955U1EU1AQE3

All the information you provided matched with my phone. As a matter of fact, I also tried my friends SIM who is on MVNO called Mint Mobile that runs on T-mobile network. Mint also allowed me to make wi-fi calling. I am surprised that t-mobile rep could not confirm this feature because this feature is on by default! If I don't want to make wifi calls, I have to turn it off. The only little annoying part is that you get constant notification," Calls will be made over WiFi". Even when you block this notification, it will reappear on the reboot

Thank you indeed for your response. When I got my S8+ and before inserting AT&T SIM, this feature was NOT listed under Settings>Connections. I was informed by a Samsung agent that the carriers will push this feature to the phone through their SIM after they provision the feature. So now since my SIM is AT&T and my phone is unlocked, and its IMEI number is not in AT&T's data base, I don't have the feature listed.
Unfortunately, I can't comment on at&t network. On t-mobile, I did not have to do anything except during the initial setup, I was asked if I was ok to make wifi phone calls when a wifi connection was available & the signal was strong. I still have the option not to use this feature. You may wantvto visit a t-mobile store or find a friend who is on t-mobile network. It might not be a bad idea to reset the phone (after backing up) when you get the new sim card. Good luck ?

That's because WiFi calling and VoLTE are not available on ATT using the US Unlocked device. You have to either buy an ATT carrier version, or flash the ATT firmware to your current device.
Try to reset to factory defaults with sim inside
I'm on Argentina and with unlocked software i got wifi calling when the device is set up with my sim inside

To access Wi-Fi calling you need to open your phone app and hit the settings button in the top right corner and then scroll all the way to the bottom and it will be there.

If you are not on AT&T postpaid plans, then please refrain from posting. I had enough research that Sprint and T-Mobile are working fine with the phone with all the advanced connectivity options.
AT&T currently has a crappy insincere BYOD policy even though they said they welcome your device. Here's the link from AT&T website about the Essential PH-1.
https://www.att.com/plans/essential-phone.html
In reality, the Essential PH-1 on AT&T will be restricted to HSPA/UMTS for voice and LTE for data. Advanced connectivity options such as HD Voice, VoLTE and WiFi calling do not work on Essential PH-1. Looking around, the same frustrations do apply for others with unbranded phones from Google and OnePlus.
How does this differ from prepaid? I'm getting LTE+ and WiFi calling. Not getting Volte though. Would it say Volte up top of it's active during a call? I get HSPA during calls.

I don't think AT&T prepaid has any of the advanced connectivity options. How do you know WiFi calling is working for you? Having the option showed up in Settings->Wireless & Network does not imply it is working. Mine has the option, too, but placing or receiving calls still drop down to HSPA/UMTS. You can check what kind of network you used on placing/receiving calls by going into *#*#4636#*#* menu.
Mine stays on LTE during calls. You have to call them and give them your IMEI and let them provision it and then reboot your phone. Did it today, works great. Never tried prepaid, standard unlimited data family plan here.

I did.
When I got my Essential PH-1 from BestBuy, I even called up AT&T rep to get a new SIM card for the phone. I provided the phone make/model and IMEI to them, since my old SIM card from OnePlus X back in 2015 was not getting these advanced connectivity options. Essential tech support recommended that I obtained a new SIM card from AT&T. I am surprised that you were able to get this done over the phone with AT&T tech support without having a case opened and wait for another 9~11 business days.
My case is currently opened and expected to be resolved by 11/30/2017. I had threatened to move to T-Mobile if they did not escalate the resolution. Researching further, I have less hope that Essential PH-1 will be fully supported by AT&T BYOD in all the advanced connectivity options. And, I am not alone with such frustrations.

I am really after VoLTE, WiFi calling and HD Voice are nice to have. Essential PH-1 LTE HSPA/UMTS indoor reception seems to be poor compared to OnePlusX from where I live.
It all works fine here. Just had to provide the IMEI for them over the phone and reboot my PH-1 after. Getting all of these features on mine, no problem.
If you register the PH-1 IMEI to the SIM you will not get VoLTE on AT&T as it is not an AT&T carrier branded phone. AT&T reserves those features for their phones.
To get around that, register an IMEI from an AT&T carrier branded phone to the SIM. Then you will get VoLTE. Unfortunately WiFi calling does not work even though the option is available on the PH-1.
My SIM is registered with my old AT&T S8 IMEI. I'm still on LTE during a call and also get HD icon on the call screen for HD Voice call also.
Quick and easy test would be to take a friend's AT&T SIM and plug it in to verify VoLTE.

I never thought of that. Yeah, maybe the difference is that a lot of us had a SIM from a previous AT&T branded phone that we just tossed in here, so when we gave them our IMEI it all just worked.
If I had to ask them for a new SIM and told them it was for this phone, maybe it wouldn't?

Strange though. In my case I've never had an AT&T branded phone with this SIM and it all still works since getting them my IMEI. Every phone I've used has been bought outright from the given manufacturer.

Regrettably, we do not support HD Voice/Wi-Fi Calling on non-AT&T Branded devices. As the device in use on the line is an unlocked non-AT&T branded device, we are unable to support those services on the device. We apologize for any inconvenience.

So for those of you who claimed VoLTE/Wi-Fi calling/HD Voice work on Essential PH-1, I would seriously doubt the validity of such claims. AT&T system is smart enough now to detect IMEI mismatch if you reuse existing SIM on AT&T branded phone. AT&T periodical system audits may disable such advanced connectivity options once it is flagged by the system.

So for those of you who claimed VoLTE/Wi-Fi calling/HD Voice work on Essential PH-1, I would seriously doubt the validity of such claims. AT&T system is smart enough now to detect IMEI mismatch if you reuse existing SIM on AT&T branded phone. AT&T periodical system audits may disable such advanced connectivity options once it is flagged by the system.

Yes that's right, we're all lying. Dumbass.

I know for a fact that I have HD voice. The dialer shows HD on some calls and doesn't on the others. When it doesn't, there is a sound quality difference.
The SIM that I'm using came from an AT&T branded HTC M8 which i l used on an M9 and then the 10... Now it's in the PH-1

LEAD up to my question.
I have a Samsung unlocked Galaxy S9 Plus, which AT&T blocks features (Wi-Fi calling, HD Voice, visual voicemail, spam blocking built into the browser, and video calling) on devices not purchased from AT&T. in order to get these features working, someone in another forum found that if you asked the 611 ATT rep to change your IMEI number to one that is allowed to enable all features on their system, you were good to go. I gave AT&T an IMEI number off a working device (My ATT s8+, not being used) that supports those features. They all worked instantly now on my s9+ without even a restart.
The problem (potentially) is I gave them the IMEI number to my perfect Galaxy S8 Plus. I just recently requested Sim unlock from AT&T and got it approved. So it's like the perfect backup phone, not a scratch on it.
And Now, to my question...
What happens when the same IMEI is used on two different phones? I did install a Verizon sim in my S8 and made a phone call just to test that the unlock worked, but that's about it. Would issue only arise if I had the S8 on the same network as the S9 (same IMEI in AT&T's system) Or does it just not work like that and I won't have a problem? I just don't know how IMEI works., forums don't normally let you post IMEI numbers so I'm assuming it's not something that means nothing. Anyone have any ideas on what kind of problems I'll be looking at with this arrangement? And any ideas to rectify it if there is going to be an issue? Thanks so much IMEI gurus
Got my AT&T variant today. Doesn't look like eSIM funcationality is enabled. Second IMEI and eSIM shown but greyed out and no way to activate. Is this true? If so, does anyone know if unlocked version allows for eSIM use so you can get dual sim? I need dual SIM for both US (AT&T) and international travel (Singapore).
no dual sim on unlocked version either

Really? Why put the eSIM in if you're just going to disable it?
well that's a bummer. Hopefully someone will come up with some firmware or we'll see a country release the 4G version of the phone that will work in the US and support dual SIM. I do, however, use wifi calling a lot and right now the iPhone seems to be the only choice that can be AT&T wifi calling compatible and dual sim.
Thanks for letting me know - i also had an order for the unlocked variant that I will cancel.

Pixel 4/4XL unlocked versions (as well as bought thru AT&T) will do Wi-Fi calling and HD Voice on AT&T (sometimes requires a little work on your part to bug AT&T).
Also, I cannot find anyway to do Wi-Fi calling on the Flip, let alone HD Voice, though it is perfectly clear with calls I have made so far.
I bought the ATT version of the flip so getting wifi calling. I didn’t think Pixel 4 was dual sim? Before various bans, I had decent luck getting HD voice on Huwawei phones but never WiFi calling unless ATT firmware (or iPhone)

Typical AT&T treatment of BYOD with regards to Wi-Fi.
Pixel 4's are physical SIM and eSIM.
Basically you can (if you find a tech who can/will) provision the account with an IMEI that supports those features, and your SIM is current, it will/should work. My 4XL is currently set up like this (and previous Pixels as well).
Thx didn’t know about the pixel 4 - I did the same thing with IMEI numbers. I bought a cheap galaxy phone from ATT for the sole purpose of having an IMEI that shows ATT. It won’t help WiFi calling which needs firmware support but has consistently gotten HD voice to work. Hopefully a different variant of the flip will show up with dual sim support that can be used on the ATT network

Slightly off topic, but if you have a minute, could you post where the setting(s) for Wi-Fi calling actually are (if there is any), I'm curious to see if they are on mine (I can't find any as of yet).
Thanks.
It gave me the option to setup when I ran. Y hone setup. It’s all under connections in setting or you can search setting for WiFi calling. I believe this is only available with the ATT firmware

I just wanted to make sure I wasn't missing something obvious, and yes, seems its only on AT&T branded device(s).
On the unlocked version, I was able to access the hidden SIM manager menu using Activity Launcher and enable the second SIM. However, even after doing so, it doesn't seem that I can do much with it.
I saw same you can see it but it's not really enabling it (under about phone, esim is still greyed out). I bought a European Version of the phone that is supposed to have dual sim enabled and is arriving tomorrow - I will report back if I can add my AT&T plan to the eSIM and use my SG SIM card on the second line and how it works. Even if I get that to work, i will have to give up wifi calling (since not an AT&T variant of the phone) and usually - Samsung pay doesn't work (but usually google pay does). i will report back. Love the phone but without the ability to use 2 SIMs, it will sadly be doing back.

I thought that the Wi-Fi calling piece was becoming more universally supported, regardless of variant. I have the unlocked version and Verizon Wi-Fi calling (and HD calling) are both working.
Hi, I got one in Czech Republic and the dual sim (eSim/normal Sim) dual standby. the setting for eSIM are under Connections>>Sim card Manager, there should be a section with eSIMS and you select 'add mobile plan' (in CZ you scan the barcode of the eSIM thats provided by the operator). Wifi calling is in the phone app under call settings and can be activated for both sim 1 and sim 2 at the same time
I got the UK version of the phone. I have an AT&T phone number on an eSIM and have the eSIM card (with the QR code). I removed the plan from my old device (a Galaxy Fold Dual SIM I bought in Singapore that worked fine with both SIMS) and then tried to "add the plan" onto my new flip. I scanned the QR code and get the message "Your mobile plan is already being used on another device. For more information, contact your service provider.: I called AT&T and advanced tech support added the new IMEI's(both physical and eSIM) to that number on their end but still getting the error. They were at a loss for a solution. Any ideas on how to fix this? Really love the phone though useless to me without the ability to use an eSIM for my AT&T number.
BTW, yes to calls over LTE (VoLTE) with AT&T SIM on UK variant of the phone and, not surprisingly, no joy on Wifi Calling
You need a new QR code from ATT. If you are using an older QR code it wont work.
Are both SIMs 3G capable?

I gonna buy the UK model and so I can use both my personal and company numbers on one phone.
My company's number is nano sim and the supports 3G and 4G
My personal number is esim and supports 3G and 4G
Neither my personal nor company number network support 2G.
I read somewhere that while Z Flip is dual sim, one of the sims only support 2G. is that right? Can anyone confirm it?
went to AT&T store, moved my old esim (galaxy fold) to a physical sim, activated and tested on physical SIM then converted it again to eSIM (new QR code). Worked! Had trouble going from eSIM to eSIM but converting to physical SIM in the middle of the process (something I read on another forum) fixed it.
