I have Samsung Galaxy S 4G with T-Mobile in San Francisco.
Whenever I go to an area without T-Mobile signal, the phone connects to AT&T. I called T-Mobile and they said that's because T-Mobile has roaming agreement with AT&T so my phone would connect.
The problem is, when my phone connects to AT&T, I can't make any calls. It says the phone's not registered. T-mobile says that's because I'm in an area that has T-Mobile coverage.
You'd think that the phone would be smart enough to figure out that only emergency calls can be made (which is what BlackBerry does and shows SOS sign). The real problem for me is that, I have WiFi calling enabled with cellular preference, and when I'm in the basement of my office building where there is no T-Mobile signal (but there is WiFi signal), my phone thinks it has cellular signal so it doesn't activate WiFi calling, yet no phone calls are coming in b/c it's not registered to AT&T's cellular network.
Is there a way for me to force my phone to only connect to T-Mobile? I know there isn't on the regular settings menu, but perhaps experts could tell me how to do so using those star-sharp keys listed here (http://forum.xda-developers.com/showthread.php?t=842134)?
Thank you!
Set wifi preferred instead of cellular.

Unfortunately, that doesn't work for me because I move around a lot, and Android WiFi calling feature doesn't have handover.
There's got to be a way to prevent this phone from connecting to AT&T at a low level somehow, no?
How do I do that? Have checked the manual but can't find location where explains how to select wi-fi preferred instead of cellular. Your kind advise will be appreciated
Open WiFi Calling and select settings. You'll see Preference. Select Cellular Preferred.
I think in setting then wireless and network, then mobile networks then network operators click the default settings.... select manual and wait for the carrier to pop up.
Will this solve your problem?

yep manual is exactly what OP should do.
if the settings for network operators are set to manual then u select the network u want and it sticks unless u manually select a different network provider. u are in select automatically mode so the phone can switch all on its own. this should solve your problem as other people have already mentioned
I have tried this many times and works as long you don't turn the phone off. After I forced the phone to manually select T-Mobile I checked many times the default setting and it remained in manual until the phone was turned off. When I switched it back on it was again in automatic mode and switching to ATT when signal is low.
Is there a way to prevent this? If not, well , first thing when phone is on in the morning is to check default setting.
5/24 I finally gave up and sold the phone. Samsung says they have not received any claims regarding this issue eventhough you see it frequently in the forums. I returned back to my HTC HD2 and will wait for the G2.
I have a friend who has this phone. The problem is I inputted the data setting for their service provider and it worked for a while, now though it doesn't work. Enabling or disabling the data settings doesn't work and on checking the Testing Menu the phone has not GPRS service and the Roaming shows Roaming also it shows that it has 3g. The 3g symbol shows up in the notification area yet it wont connect however Wifi works and Calling and Sms work as well.
I would factory reset the phone but my friend doesn't want to do that. Is there anyway to fix this.
I picked up a G930R4(US Cellular) to use on Total Wireless. When setting up the phone, it says the sim is invalid but it connects and continues the setup fine. I have to enter in the APN manually. After that, It works fine but it gets stuck roaming. I have to toggle airplane mode on/off to call out or receive calls. And sometimes it will get stuck on band 1 with poor reception.
I flashed the latest Verizon firmware thinking that should work because TW is a Verizon MVNO. Got through setup fine but it always roams no matter what network settings are. Cannot edit or add APNs with that firmware.
I tried the U firmware, it wouldn't connect any data. Unable to add any APN with that firmware also.
Any suggestions on what to do to get this working correctly??
I'm running stock Pie on a regular Pixel 2 and am having some trouble with WiFi calling. It'll show that it's connected at the bottom for a while after a reboot like in the picture but then randomly revert to only saying MetroPCS and not send or receive texts or calls when I'm in a dead network area. I've reset network settings and downloaded the carrier service app but I'm stuck and frustrated now. Any ideas?
Now I'm off again even though it's still enabled
Hi,
I found one short thread about this. But are we sure that there is no other way to use Wifi Calling ? I have a non-network phone, an LG G7. I don't want to change it ATM. Why do the networks tie Wifi Calling to the firmware like this and is there any way round it ? Cheers.
With my carrier, Wifi Calling only works with its SIM on any phone with any firmware on which Carrier Services runs or can be installed. No SIM no Wifi Calling.
You can look for services that will connect you via vpn and allow WiFi Calling, but you are always identified. Calls cannot be anonymous.
