Google Fi Network Switching S20 - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

What is preventing this phone and other nonGoogle phones from network switching? Is there anything that can be done to allow network switching?
It does not need to be automatic but I would like to use US Cellular at my In laws house and T Mobile almost all the rest of the time.

They don't have wifi you can jump on? VOIP works perfect for me when out of location.

Their wifi is pretty janky. I am going with the Samsung anyway as the Pixel 5 is pretty underwhelming for more $. I just was hoping there was a way through root access to select my network.

Wifi calling - preferences - disable cellular radio

Searched for other threads but didn't find anything that specifically addressed this. It's probably old news to many but I hope this helps out other noobs.
In Galaxy S2, enable wifi-calling and you can change the connection preferences to
1. Wifi preferred
2. Cellular preferred
3. Wifi-only.
Options 1 and 2 are self-explanatory, but I didn't quite understand why anyone would want to select 3 over 1, until I tried it out.
When I selected wifi-only, the cellular voice signal bars are dark. I think this setting essentially disable cellular voice radio.
This is important if you travel abroad and want to use the wifi calling feature because wifi-calling cannot be enabled with airplane mode on. Also I don't think wifi-calling works with a non t-mobile sim card.
I'm on Wifi-Preferred and my radio is always disabled automatically
From the company that makes the wifi-calling tech for T-mobile
http://www.wificalling.net/help/
It is possible to configure the Wi-Fi Calling Application to enable calls over Wi-Fi only, essentially keeping the phone off the cellular network. If you set the Connection Preference to Wi-Fi ONLY, the application will work over Wi-Fi and, when you go out of range of a Wi-Fi signal, will NOT accept or make calls on the cellular network. This is similar to putting the phone into AIRPLANE mode with Wi-Fi Calling.

[Q] Note 2 not auto switching to 4G?

Hi guys, I'm plenty familiar with the Note II having had mine since October release. I'm having an issue where I will be in a solid 4G coverage area (at my home) and my phone will stay in 2G mode.
There is a problem with either the tower or the phone, I'm leaning toward tower because my wife has my old Sensation 4G which is also staying on 2G. Have any of you encountered/noticed that your phone stays in 2G even though you are in a 4G coverage area? For me either on the Sensation or Note II, I just pick WCDMA, 4G pops in and works great. The only problem is that I have to remember to put it back on auto when I leave the area. I looked up and attempted the cell codes for making the phone prefer 4G, but without success there. Also my phone picks up 4G automatically when I'm at work, so again leaning toward tower (but how and why the tower can control this I have no idea).
I also noticed some threads claiming wifi calling would detect wireless networks nearby and disable 4G. I'm leaning towards BS on that because 1. my wi-fi is almost always turned off (true unlimited 4G plan), and 2. when I disable wifi calling all together it still exhibits the same behavior.
I'm running out of ideas - any help is appreciated!

In settings>more settings>mobile networks>network mode:
You should ALWAYS be set to GSM/WCDMA (Auto mode)
This will automatically get you the best data signal available at your location. If you only get 2G in some locations, that's normal. You can try calling TMO support and have them check your address to see if you SHOULD have 4G at that location. If you really want to try to see what is going on, install an app called Open Signal Maps form the Play store. Among other useful things, it will geolocate the towers you are connected to complete with distance and mapped street address.
Where I live I only ever get 2 or 3 bars of 2G data. I use the TMO wifi calling app for all my calls and texting. This is only way I can get reliable service at home.

Thanks for replying vouty. When I switch from auto mode to WCDMA I have 4 full bars. That's the funny part. Speedtest is giving me around 12Mbps down 3 up on average (I live right by the tower - like .5 mile), so there is for sure something strange happening. If I keep wifi on it really isn't an issue, but I prefer to not mess with wifi and just keep it in 4G while at home, but as frustrating as this problem is, the phone refuses to switch from 2G on it's own. Once I toggle from AUTO to WCDMA, and then back to auto - it will stay on 4G. It's almost as if I am waking it up and causing the phone to re-detect the signal.

Cool app, very useful, appears I am on 3g at home. Turning off wifi to see if it changes to edge while using data.

Will it support T-Mobile WiFi Calling?

Will it support T-Mobile Wi-Fi Calling? I know Android M supports WiFi calling natively but will the carriers (T-Mobile in particular) need to do anything to allow it?
WiFi calling is very useful to me at home where cell signal is very poor.

Out of the box, at this moment, I don't think it does. However T-Mobile got it working on the Nexus 6 so I don't see why they couldn't add it with an update either before or after they ship. Think positive :thumbup:
Edit: found this from another thread in general section
"It’s also worth mentioning that*T-Mobile has already said*that the Nexus 5X and Nexus 6P should have Wi-Fi Calling support at launch. While it’s expected to be turned off by default, T-Mo has said that after you pop in your SIM and hook onto the network, you should be able to turn the feature on."
Google or T-Mobile said via Twitter or the AMA or somewhere that it does support WiFi calling out of the box, but you need to set it to be on when you get your device - it isn't on by default.
The TBD support is for T-Mobile VoLTE/Band 12, which Google said they hope will be ready to go by ship day.

Excellent. Both will help.
Do texts go over wifi as well with wifi calling enabled? At work I only have access to wifi or Sprint (because I am in a basement of a building) and it has a Sprint DAS antenna system installed. I was thinking of switching to Project Fi due to it being on Sprint's network but if texts can go over wifi with T-mobile I would probably go with them since it would open me up to a huge choice of phones in the future (I kind of want to try a windows phone sometime)

Yes, texts will go over wifi. Hurry with that Windows phone, before the platform dies completely
Here's the Twitter post where I saw confirmation from T-Mobile on Wi-Fi calling: https://twitter.com/TMobile/status/648919023158206464
The initial question was on band 12 support (hoping we get this soon), but below there's a question on Wi-Fi calling to which they said yes. This was one of the main reasons I'm switching to one of the new Nexus phones - most phones support it on their stock ROMs, but once you get sick of stock and switch to a custom ROM you have to give up Wi-Fi calling.
Question for those of you on T-Mobile...
We all know WiFi calling is enabled, BUT, has anyone seen or regularly sees any kind of indicator that they're actually connected through WiFi calling when on a call?
I have seen twice on the signal tile, it say "T-Mobile WiFi calling". But that's it. I have the setting set to WiFi preferred and I even have the T-Mobile WiFi calling Asus router, but I don't know if it's actually using WiFi calling it not.
If I have zero signal indicated on the signal tile, but WiFi on, I'll get a message telling me to connect to a wireless network when I try to place calls.
I'm also assuming that means the signal indicator tile serves a dual purpose in regards to also showing WiFi signal strength. Because when I'm on WiFi, if I switch on " cellular preferred" (in WiFi calling settings), I'll see the LTE symbol next to the signal icon in the tile, but If I switch to "WiFi preferred", any cellular symbol (LTE, H, 3G) goes away.
On a side note, if you're in airplane mode, you can't make a phone call, even with WiFi on. On my S6 edge, I could, as long as I was connected to T-Mobile WiFi calling. But the phone would let you know with a status bar icon.
I really need WiFi calling in some places at work and I dumped the S6E partly because of the 5X utilizing WiFi calling, so that's why I've wasted all you folk's time in reading this long post. ☺
Well, son of a *****, look what finally popped up...
It was enabled by default as soon as I booted with the TMO sim and ran the update.
Great to read...looking forward to trying it out when it arrives.

As was mine, but it didn't seem to want to work. I had "cellular preferred" set, but it seemed to hold onto the cell signal too much and not want to switch over. I set it to "WiFi preferred" but it still wasn't connecting yesterday. Today however, it's been all good with WiFi preferred. So it might have just been my work's network yesterday.
I still got to see if the phone will hand off the call to cellular before I leave it on WiFi preferred. I'm guessing it only will if I'm on band 12, but I'll test it anyways.

LTE Disconnects Frequently

On Project Fi and I've noticed that my LTE / Mobile Data goes "!" often, usually when I move from Wifi to Mobile Data I'll notice it, so I'm not sure when exactly it's happening. Simply toggling data off and on again has resolved it instantly.
I've run into some issues with Wifi as well on my work network doing the same thing, although my home network seems fine. Toggling wifi on and off seems to fix this as well.
Just super annoying and honestly an issue if it's happening when I have no network and can't receive texts or something because of it... (Haven't actually checked if it effects texts etc. I'll check next time it happens and report back)
Same issue here. I think I'm returning the phone.
For me, I have to turn off mobile and turn it back on.
Please let us know. I am on project Fi and I am worried about compatibility.
I already know going into it that I am losing my network switching capabilities in addition to losing the Google VPN function and autoconnecting to Google partnered secure wireless networks.
However, with the bull**** Google pulling trying to give me $260 for my pixel 3XL, which is less than a year old, I refuse to buy another pixel device until they get their **** together.
I have checked tons of boards and I don't see anything about OnePlus 7t users and Project Fi. Just speculation.
Thanks in advance!

I am on Google Fi and noticed the same issue. The problem is worse when there is week wifi signal and the phone switches from wifi to cellular. Sometime I want to wait until the ! disappear, but it just stay like that until I toggle the cellular or airplane mode
Same here. Doesn't always switch from WiFi to LTE when I leave the house.

WiFi Calling Issues

I have terrible cell signal at home, so rely on wifi calling to make my phone function as, well, a phone. However, recently something has changed where WiFi calling no longer appears to work even though I have it enabled. Actually, that's not strictly true, it works, but only randomly and seems to not be available the majority of the time.
Previously, as I could often get 1 bar of signal, what I would do is enable airplane mode, then turn wifi back on to get wifi calling working. However, this no longer works. I have reset network settings, re-enabled and registered Wifi calling, checked with my provider that Wifi calling is available, used the Samsung Band Selection app to set to prefer using Wifi calling over cell data. I'm sure there are other things I have tried, ultimately, nothing seems to work.
Wifi speeds are good, I'm at the end of my rope with it.
It's a Sprint (T-Mobile) phone, still on a Sprint SIM here, spent an hour with support yesterday and they basically had me repeat everything I have already tried before telling me they will have to escalate it.
Anyone else having issues? Any idea what to do?
Thanks.
Not sure if this will help, but you might want to look into what port wifi calling uses and make a port forwarding entry in your modem. I just remember long ago when tmobile had their TM-AC1900 router,something about it having certain ports open to allow for wifi calling. This was before they released their 4g lye personal cellspots.....this was a wifi cellspot

These may help.....
P.s i have Xfinity for home internet and tmobile for a carrier.....my wifi calling has been weird at times out of the home while connected to Xfinity hotspots......and long story short, now that Xfinity has their own cell service they may be crippling ports....just a thought....manually forwarding those wifi calling ports should fix that if that's the case....
