eSIM question w/ Project fi

This question is for those of you like me that use more than one phone with a single SIM card. Sometime I travel and switch my SIM to another older phone I have around so if I lose phone #2 traveling I still have my newer/better phone. I know I'm not the only one to do this If I put eSIM service on Pixel 2XL, can I put old SIM card in Pixel XL and continue service on that phone while traveling. Is there a way to temporarily disable eSIM?

Hmm, interesting question.
I went with eSIM on my Pixel 2 XL yesterday, allow me a few hours to fire up my Pixel XL (which is currently powered down but still has the physical SIM card in it) and see if the Project Find app can reactivate service on it - and then move service back to the eSIM on the Pixel 2 XL again.

I hope Pixel2 can ultimately support dual SIM (eSIM and physical SIM) simultaneously with eSIM opens up to all carriers (not just Project Fi).

I am in a similar position and asked Project Fi pretty much the saem question. My Pixel XL 2 is on esim now but I want to be able to switch back adn forth from att and project sim (depending on which of my phones I will be using.)
They said that yuo can put an ATT SIM card into the phone, go thru sim setup to activate it - and later take it out and re-establish the ESIM when you wnat to use it on project Fi again. It will just take you back thru the saem setup process you went thru when you initially turned on the ESIM.
Pretty straight forward I think.

Thanks. I removed the fi sim from the XL2 and cleared data and cache in settings/apps/project fi and went back to fi app and set up esim so phone is good now. I need to see what happens when I put old sim into XL, haven't done that yet but I assume when I go into fi app all I have to do is reactivate service on that phone and it will be active (and disconnect service on XL2).

I was wondering the same question

The old physical SIM is now disabled. The eSIM has taken its place. The only way to go back to a physical SIM is getting a new Fi SIM and activating service on that SIM. There is no difference between eSIMs and real SIMS other than the eSIM is virtual and issued 'on the spot' during setup.
If you guys run the Project Fi app for setup, you'll see it's asking if you want to "Move your number to this phone" => transfer main phone to this eSIM an cancel original main SIM OR "use this phone alongside main phone without calls or texts" => make the eSIM be just a data SIM in the account.
In summary, if you are planning of using only the Pixel for Fi alongside some local/USA carrier it makes sense to transfer your main SIM to the eSIM. Otherwise it maybe be better to keep the original regular SIM.

I finally tested this. I had new esim service in new P2XL and old sim in PXL, old sim disconnected of course. Turned off P2XL and booted up PXL, had notification from fi app that service has been disconnected do I want to activate, pressed activate. It took a minute then fi app said do I want to maximize service, I said yes, another minute and I have service. Checked what network I'm on and it says Verizon, that's weird so I make a call and it rings VZW customer service, I hang up. Reboot and it comes up with Sprint this time and service is normal and I can make calls on fi.
I then turned off old phone and turned on new P2XL, it asks me the same exact questions do I want to activate service, I say yes and let it do its thing and reboot and have fi on that phone w/ esim. So for now it looks like we can use old sim in other phones w/ fi but that could change.

This was not my experience:
Powered down Pixel 2 XL, which was activated using eSIM three (3) days ago
Powered up Pixel XL (which I performed a wipe/reset on before I powered it down), which still has the Fi physical SIM in it
Pixel XL booted and tried to auto-activate on Project Fi; hung for a ~three (3) minutes before failing and asking me to hook up to wi-fi & sign in to a Google account
Connected to wi-fi & signed in using the Google account the Project Fi subscription is associated to
Project Fi attempted to activate again; hung for ~three (3) minutes before reporting: "Activate service later. Unfortunately your Project Fi service can't be activated right now. You'll be prompted to activate as soon as you've finished setting up your device."
Completed initial login on Pixel XL; had a Project Fi notification which read "Project Fi not fully activated. Tap to finish activation."
Tapped this notification which took me back to an "Activating..." screen which hung for ~three (3) minutes before failing with the following error: "Contact us. Unfortunately, your Project Fi service can' tbe activated due to an issue with your SIM card. If you need help, call 1-844-TALK-2-FI. Code: T077."
Powered down Pixel XL
Powered up Pixel 2 XL and confirmed Project Fi service was still activated/operational on eSIM.
In short, my experience is that one would need to engage Project Fi Customer Service in order to move from eSIM to physical.

With this phone, and the eSIM, you can switch between physical SIM and the eSIM. I first setup my phone on Sprint, but wanted to try out Project Fi without giving up my existing Sprint plan. It took some work and some calls, but both services are active, and to switch I use the dialer code *#*#switchsim#*#*. There is an option in the settings area, under Mobile Network then Carrier, but it does not seem to work all the time. I'm not planning on keeping this setup long, especially since on Fi I cannot use a Sprint connection, as I was told that my phone is still registered on the Sprint service. When I try to connect to a Sprint tower through Fi, I have no data. So while this is not an actual dual SIM phone, it appears that it can function as such, so long as you use Fi, and the second network is not Sprint or T-Mobile (or US Cellular.)
I don't think this applies to the original post, but I just wanted to share my findings in case can help anyone.

I asked Project Fi support if I could use the e-sim for data only and the sim slot for a call/text.
they said e-sim is only for full service (call,text, data).
Hoping Tmobile will support e-sim soon

So your saying if I popped a Verizon SIM in the physical slot and pushed my personal number to Fi it'd function as a true dual SIM??? That'd be amazing. My current setup Is a OnePlus 3T with my personal ATT and work Verizon SIMs. Verizon doesn't get data cause the 3T is missing Verizon band 13. I still get texts and calls though.

No. It is not possible to have both SIM and eSIM active at the same time, it is one or the other.
You can switch between them at will, but both will not be active simultaneously.

You'd have to ask Google. And I have not seen anything via root to enable it.

Unlocked S9 cannot register on Verizon MVNO?

I've got my unlocked S9 from Samsung. I have a Redpocket CDMA sim card, which works fine in a Samsung S7E and a Google Pixel. However, when putting this sim card in S9, the S9 could not get on its network. It shows Emergency calls only and "Not registered on network" when making a call.
Sometimes it shows "refreshing sim card data" and no network. When turning to network modes, it says "LTE/3G/2G" etc but redpocket cs seems to believe the right one should be "LTE/CDMA" instead, which is not in the list.
I tried various usual ways such as factory reset etc, which did not change anything.
I tried a project Fi and a verizon sim card in the S9 and they were recognized with no problem. Thus I think the S9 is not defective.
I did some searches and people mentioned S8 had the same issue too: https://forum.xda-developers.com/galaxy-s8/help/unlocked-s8-failed-to-register-red-t3736850
I am wondering whether anyone has this problem or a solution.
Will flashing to verizon firmware help?
Thanks.

I'm having the same issue with PagePlus! I just put the SIM from my VZW S6 into my unlocked S9 and when that didn't work I chatted with support to do an ESN change (I thought perhaps PP needed to do something on their end). I was told if there was no "LTE/CDMA" option that the phone wouldn't work on PP.
I tried using an app to switch between different network modes (including the LTE/CDMA/UMTS auto which my S6 uses) to no avail.
I'm tempted to try flashing the VZW firmware, but the post here makes me wonder if it will accomplish anything.

I tried that APP to force network mode too but it did not seem to work.
As an update, Redpocket customer service is really great that they moved my number from Verizon network to their GSM/ATT network, and everything works fine now. I do not want to try flashing verizon firmware for the same reason...
Too bad Samsung could not get such a simple thing right.

Can we sue them?
I faced the same issue too. Apparently, Samsung does a setting update that prevents the sim from registering for Verizon's MVNOs. I called them and they said they NEVER heard of this issue. Apparently, you all did too. I am tempted to sue Samsung for this since this could be an antitrust issue. They are preventing competition by working with Verizon and feigning ignorance.Can any of you comment on this?

I was going to go with one of Verizon's mvnos. And their SIM card would not work and I did not realize it until I spend the $40. I had to put an actual Verizon sim in my unlocked phone to use the Verizon network. So either Verizon is blocking the S9 on mvns or the mvnos don't have the updated information for the S9. Total wireless told.me it Had to be a Verizon branded phone for it to work. So I think if someone flashed the Verizon firmware on the unlocked version it probably would work.

i dont see anywhere on the post where you contacted the MVNO provider, to register the ESN or IMEI of the device.
Also does this MVNO even allow BYOD?
i remember I had a line from Cricket or Metro that had a sim card, it worked on my Nexus 5x, however inserting it to another nexus 5x, it didnt work, I had to call them to register my IMEI

Hey guys this is an old thread, but maybe this will help someone. My old Red Pocket SIM would not work on the S9, but my renewal came with a new SIM, ending in 8222-15XX (old was 8180-50XX) For ****s and giggles I put it in and it showed LTE/CDMA and verizon. Had RP CS switch my active SIM and now it works with no workaround!
TL;DR Try a new RP SIM if you are using one a year old or older.

I also have similar issue.
Where I used to get lte over voice, but no longer getting after a recent update from samsung. Using Redpocket cdma sim
Now I have lte and voice, but dont get lte over voice even though redpocket said they have enabled Volte on my line

We just added an Unlocked Galaxy S9 (replaced S5) purchased from Amazon (Black Friday sale), ordered new Sim from Pageplus (MVNO using Verizon ), called them to transfer the phone number, popped it in and the S9 configured itself for Pageplus, and everything works perfectly...

That's great news. I switched to GSMA due to CDMA issue. I will switch back to CDMA after my current plan expires.
I heard that RCS (messaging via wifi connection similar to imessage - samsung messages app supports it in pie I believe, not sure about oreo) is active in verizon now including mvnos. Have you tried it?

I tried for my unlocked note 8. For the new sim coming from red pocket, it works great at the first time. But later when I switch the sim to a GSM sim for international travel and then switch the sim back to the red pocket sim, the same problem appeared. I have to use verizon sim to get LTE/CDMA back in the emergency mode.

Traded in my S9 with an S10+ and the redpocket CDMA sim works now!

I think you've found the answer for those who are unable to get their existing RP SIM to work on the S6-7-8-9's running OREO or PIE. I just took a later serial numbered CDMAV SIM (89140000018821472XX), inserted it into another S8+ that I have, booted it and saw the Verizon Wireless scroll across the top. I'll chat with RP today and see if they will switch the ICCID numbers between old and new.
After countless hours looking into this problem, I tip my hat to you for the solution provided.

Try as I may, in the end it didn't work for me.

It worked for me when I flashed the latest un-branded U1 firmware G960U1 UEU6CSI1 via the patched Odin, from:
https://updato.com/firmware-archive-select-model/?record=E68EDDB6DBFB11E99E59FA163EE8F90B
I've also done a full factory reset from recovery after the flash.
I guess they must have fixed it with the latest firmware updates... ymmv

Since the August update, both of my Verizon branded S8+'s work directly upon inserting a RP sim card.

POSSIBLE SOLUTION!! (YMMV)
I had a similar problem when I upgraded to Android 10. I no longer had CDMA as a choice for Network mode. Here is the solution that worked for me:
Step #1:
Go to the phone dialer and dial *#*#4636#*#*
This will bring up a new screen
Select "Phone Information"
You will be greeted with a scary-looking screen with lots of stuff
Scroll down and look for "Set Preferred Network Type"
Select "LTE/CDMA auto (PRL)" from the drop-down
This will give you phone service... but not data.
STEP #2
To get data services, you will need to create an APN.
Go to settings/connections/mobile networks/Access Point Names
Click on add and enter the following:
APN Name: Verizon
APN: VZWINTERNET
MCC: 311
MNC: 480
Authentication Type: None
APN Protocol: IPv4/IPv6
APN Roaming Protocol: IPv4/IPv6
I found that this APN worked for me... (YMMV)
Hope this is helpful...

are you folks still having trouble with this? it doesnt seem like a difficult obstacle to overcome

Thank you sooo much! Creating the APN did the trick.

I got 4G working on Verizon!

To preface this... I still cannot make calls, as those use CDMA, but I have data. I use google voice for calls anyway, so having no cdma is no skin off my back. This will probably work for the Pro or Mate 20
What I did:
Through Verizon chat, I requested specifically that the agent put in a request to add my IMEI to their database. I told them I know the device isn't supported and that I won't be able to make calls, and I am OK with that.
I added this APN information: https://apn.gishan.net/en/apn/verizon/huawei-mate-10
I turned OFF carrier aggregation
I then put in my tmobile sim for a week in the other sim tray, turned off the vzw sim, and let it sit for a week. I only enabled the sim slot a few times throughout the week, and today it finally worked. My guess is it took them some time to add the IMEI to their database.

I'm interested in using the Mate 20 X on Verizon too and also use Google voice but I see the Mate does not support LTE B13 700c. Is that an issue?

Can't connect to mobile network.

I have a pixel 3xl, up to date stock non rooted, on straight talk lte/cdma Verizon network. I got a text saying straight talk now has VoLTE so I tried to find it in settings but there's no option for it. When I search it it comes up but when I click it it goes to mobile settings and it's not there I did the *#*#4636#*#* and it's also grayed out there. I changed the network mode in that diag screen to lte/cdma to see if that helped, was on global before i think. Still no VoLTE and for some reason I can't make calls. I have data, can send and receive texts but when I go to call it says no network. Removed Sim card didn't fix it, restarted it. Safe mode doesn't help either. Tired clicking trigger carrier provisioning, updated the smsc. Change mobile network to lte only, back to global, lte/cdma. I have no idea what else to try. Straight talk is basically useless for customer service so I haven't even tried yet lol.

Update!! It works!! Somehow I either damaged my sim card when I switch from my pixel 2xl to this 3xl and it somehow lasted till now. Or when I changed my network settings something wrote to the sim?( And it messed it up?? IDK much about how the phone and sim interact with each other)... But I did have a 2 year old sim card, it did not have VoLTE or wifi calling capabilities I now realize. So I bought a new SIM card at Walmart and activated it though the straight talk app on my account and kept the same number. Works perfectly and I now have VoLTE, no wifi calling yet but the option is now there and lets me click it but it fails. Doesn't matter to me, I'm just happy to have VoLTE. I'm leaving this post because straight has horrible customer service and I could find anyone who ran into this specific issue.

LG G710ULM UNSUPPORTED VoLTE ?!? (Straight-Talk US - T-Mobile network)

*********UPDATE********** I bought a new sim from straight talk and VOLTE works now! (GSM compatible Straight Talk Sim card) My old sim was from 2014, so it wasn't VOLTE compatible.
I have an ebay zombie LG G710ULM flashed to latest Google Fi Android 9 software, I received an email from Straight Talk (Wal-Mart US cell phone service reseller) telling me that my LG G7 does not support VoLTE and my phone will be unable to receive calls in January 2021.
-Using a network info app, the app is telling me it is connected to T-Mobile towers (so I have a Straight Talk T-Mobile compatible SIM)
-I can't find any options to enable VoLTE in settings, and wifi calling is erroring out
I was wondering if there are ways to get VoLTE and Wifi Calling working (Straight Talk supports it, but not my current ROM/SIM).
I can switch to the following sims supported by Straight Talk.
-AT&T Compatible Sim
-Verizon Compatible Sim? If my phone supports CDMA bands
OTHERWISE MOST OF US WILL HAVE A PAPERWEIGHT IN 2021!!!!!!!!!

Same problem
I'm having the same problem. Any progress on this?

I'd like to know this too. Surprised there is no traffic here with all the knowledgeable people on this forum.
G710EAW here. BTW There was an Android 10 update just two hours ago from Android 9. Someone with an 'EM' phone in another thread said VOWifi is "working now" but how do others know if it's working when January 1st comes around?

If you guys have cross flashed roms, then volte will not work. It doesnt work for any of us who have crossflashed. Whichever model.
You need to be on original software. Looks like some licensing thing that volte requires. They need to provision volte for all the phones. Sounds like they are not interested to provision it for g7. Odd that even EAW model which has original firmware, they sent that mail too....
Sad/Odd to see your carriers are suddenly changing to only Volte.

Is there a way to put it back to original software? I actually don't need it crossflashed to anything because it's a Verizon originally and I would like to use it on that network. Or does it not work that way?

Main issue is that your carriers dont want to provision volte for your G7s. So no guarantee if cross flashing back to original will work.
There is crossflashing guide in guides section with which you can go back to stock firmware. Do this at your own risk.
In our country we have a volte carrier called Jio. They provide an app called jiocall. Using that app you could use their service even if your phone is not volte capable. You will have to see if there are such apps for your carrier. Thats the only non technical, simpler solution.

I have some information that might make all of you guys happy.
I was told by Safelink Wireless that VOTLE is a function of BOTH the phone *AND* the sim card.
Basically, if the phone itself is VOLTE compatible but the sim card is not, then the phone will be reported on their system as not compatible, and will ask you to upgrade your phone.
However if a VOLTE compatible SIM is inserted, if the phone does in fact support VOLTE, it will then work. That's because it's provisioned on the carrier via the sim card itself.
If you purchased a sim via the "Buy your own sim" package, e.g. online or from Best Buy, etc, awhile ago, then that sim is not compatible. You simply need to call Tracphone/Safelink and ask to buy a VOLTE compatible SIM (which costs 99 cents). Then when you get it, call their tech department to have them transfer the phone service and phone number to the new SIM.
You can dial the phone's service menu and go to the VOLTE/GPRI menu and if the options are there, then the phone supports it.

What's the correct service menu number for our phones?
