XZ1 on Project Fi Working

I came from a Nexus 5X on Fi and wanted to make it known that I had zero issues running service on my Xperia. As long as you have the app installed and the sim card in everything will work as intended. Fi will claim that the phone cannot be used for service but most likely the phone will only use TMobile if it's unable to truly switch between networks, which is fine. When sending messages in Hangouts it'll note "Sent via Google Voice". Calls over WiFi and cell work well. Couldn't say I've tested out switching between cell and wifi but I would assume Android takes care of that.
One important thing to note as far as I know you will not be able to start Fi service on an Xperia you must have a Google phone or the Moto X4 to activate a Sim card.

So if I understand it right, this is essentially the T-Mobile network (less volte) for Google Fi pricing/plan, correct?

For the most part, plus you get the great functionality of being able to use Hangouts for calling and texting from any device. It's basically Google Voice with T-Mobile cell service. From my experience though where I live I almost exclusively seemed to be using T-Mobile every time I checked when I was on my Nexus. Fi doesn't seem to activate the VoLTE option, nor does it for wifi calling in the Android Dialer. I am on the international version firmware however so that may be part of the issue. Using Hangouts Dialer for calls does work however over both cell and wifi.
Also forgot to mention, all the APNs and everything were already set up when I put my SIM in prior to the first start. Looking around in the mobile networks menu it seems Android and/or Sony's software is capable of switching preferred networks automatically.

so how has ProjectFi bee nworking for you on your xz1 compact?

Can't set android pay as default payment app

Hello.
Some time ago i bought used Motorola Z Play on ebay from Germany. I thought all Z play have dual sim but i wrong.
So i unlock bootloader, root my phone and make my phone dual sim ( i used this thread https://forum.xda-developers.com/moto-z/how-to/guide-to-enable-dualsim-singlesim-t3594529)
and install magisk.
Long story huh? So that's the problem.
I can install Android Pay and can add credit card. But i can't pay by Android Pay.
I think it's because i can't set Android Pay as default payment method.
When i install AP he ask me 2 times:

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I click yes but nothing happens and in Tap and Pay i see nothing.
I tried to install diffferent apps which can use NFC and these apps appear in Tap&Pay just fine.
So please help me understand what is the reason? Why i can't set AP as default payment app?

Do you pass both safety net tests? Does RootBeer sample detect anything if you set it in Magisk hide?
I'd bet it doesn't let you pay because it detects something. Making a single Sim device a dual SIM one is probably too much

Hello. Thanks for answer!
Yes, Magisk show all safety net test passed
And rootbeer shows all green.
It drives me crazy.

I installed Google Pay now and icon set as default not working. I can't click on it

Question Default SIM card on Messages

I have been trying to achieve this on the Poco F3:
I want to set SIM2 to be the default card for all new messages/conversations . Is this possible?

You can easily do that in settings.

I don't have that option. Any clues on how to enable it?

U have 2 options:
-to select which SIM will handle the calls (fist one);
-to select which SIM will handle Mobile Data (second one).
As I see, u have both SIMs to handle calls, and SIM1 to handle Mobile Data. I just suppose that SIM which handle calls handles SMS too (I do not have 2 SIMs in my phone), so try to select SIM2 in first option and see what happens with the SMS.

If I select default for calls for example SIM1, nothing changes, I tried to switch mobile data to the other card and still nothing happens too, in fact, i never saw the option showed by FlyingDutchdude in my SIM settings.
The way I have set up SIMS for calls is that it asks which one before calling. But that should have nothing to do with SMS. The data card too, both should not be a dependency for the default SIM card in SMS. Correct me if I am wrong.
Thanks for the reply

Do u have stock ROM? Try do to his combo (calls SIM1 and Mobile Data SIM2) and see if his SMS option is showing/activate on ur phone too.

Seems that what u want is not possible (at least referring to 2020) https://c.mi.com/thread-3148384-1-0.html

Well that's too bad. I'm using latest stable version. I wonder what is the ROM used by @FlyingDutchDude... Thanks

cannot get apps to use mobile data?

Hi All
I have an xperia XZ2c that I purchased used, but cannot get the apps to use
data outside of a wireless network.
This is very annoying as it means I cannot use spotify, maps, gmail, etc
over mobile while travelling.
I have tried absolutely everything I can think of, with no success, so now
I have come to the experts - if the XDA crowd can't figure this out, then it
probably cannot be fixed!
Some background:I bought the phone over ebay, and it's originally from
japan and was locked to the docomo network carriers.
I have unlocked the network, and am able to use it to make calls, send messages etc. So the
voice works fine, it's the data that is the problem.
Model: Sony Xperia XZ2c SO-05K
Carrier : Docomo
Build: 52.1.B.0.266
Root status : not rooted
Bootloader unlock allowed = no
Some obvious stuff:
Do I have data? YES
Is mobile data enabled = yes
Did I try roaming = yes
Is airplane mode on = no
The phone info states:
Sim status = NTT Docomo, which is incorrect, and should be vodacom - how do
I change this? Sim is working for voice though.
Another oddity:
I have used adb to disable the bloatware, but when I tried to disable an app called ‘docomo application manager”, it just re-enables itself – whats up with that?
If I cannot get this to work, would a last ditch attempt be to try and get the bootloader unlocked at the cost of more $$$? I would prefer not to, as I have read that it can affect some functionality such as the camera, and quite frankly it looks like quite a complicated process for a noob such as myself.
Thanks in advance for any suggestions.

Having the exact same problem (added the providers APN data, it was empty. bootloader unlocked allowed is no, sim is unlocked). Feels like the phone does not support the needed bands but according to the spec sheet it should.
Anyone else ran into this and managed to solve this problem?

Question Can't switch 5G off since updating to Android 13?

Has anyone else has this option greyed out?

I have the option to choose between 5G,4G,3G,or 2G (Settings > Network & Internet > SIMs > Preferred Network Type).

Yep they've greyed it out even though my phone was bought simfree (unlocked)

If you scroll down a bit further, don't you have a Preferred Network setting?

Nope just a 'Choose Network' which is also greyed out

I'm at a loss, hopefully, someone else will chime in.
FWIW, mine is a US Model, puchcased from T-Mobile, SIM unlocked (using a T-Mobile SIM Card).

You could always just use the dialer code *#*#4636#*#*

Turns out certain networks have the option disabled, I had the same problem when using an ID Mobile sim but my Vodafone sim was fine. To fix the problem make sure your rooted as I don't know of any other way other than the one I'm going to show.
Use a file manage that can show you root files (I use MiXplorer)
Go to /data/user_de/0/com.android.phone/files
Look for a XML file that starts with "carrier", If you have more than one then you've used more than 1 SIM in the phone, Make sure you've opened the XML file for your SIM.
Look for the line "hide_preferred_network_type_bool" and change it from true to false.
Reboot.
Profit.
Hope it works for you.

I'm with Smarty (owned by Three) which also uses the Three network like idmobile so it looks like Three maybe the cul·prit

I'm on I'd mobile which uses threes network.
Type this *#*#4636#*#* in dialer, it enters a test mode.
Click on phone info which takes you to another screen.
Scroll down and you'll see a slightly gray box that if you click on that and scroll through you'll find LTE only.
Click it and that's it, 4g network only.
Restart phone, job done.
Pretty sure my battery also seems to last longer
