Im on a a VZW TP2 with stock 6.1
when WiFi is on and connected, Visual Voicemail errors out saying "no network connection, cant connect to the voicemail server", even though 3G Data Connection is also turned on at the same time in Comm Mgr.
Im assuming VVM is trying to connect to the server through the unauthenticated WiFi connection, instead of the preferred 3G Data Connection. Is there any way to force VVM to use the 3G Data connection and ignore the WiFi?
Or, it may just be a Verizon thing...is anyone having this problem on other carriers?

for some reason, my phone keeps going to 'no service'. i have set it to gsm for network type and auto for gsm/umts.
i installed the no data cab because my phone always keep getting connected to the internet after turning off data connection and 3g. i even went into task manager and i don't know what else to disable that connects to the internet. that's why i installed the no data cab.
after installing the no data cab i noticed the 3g is turned on in communication manager, and i get the bars and see the big H. i turn off the 3g, and then i get no service, but then no service again.
i then went into network connection and chnaged gsm to auto. and now it works with the big H and the 3g is turned on, but even when 3g is turned on, i can't connect to the net unless i toggle in the no data cab program.
anyone please help!
radio issue?
do you think it's a radio issue?
i think its just telling you that ur in a 3g/HSPA area not that ur actually connected to 3g
but it didnt do that before, it would just be no service and I would have to change to 3g..not sure why.
True, the 3G or H icon will sometimes show up to tell you that those signals are present, even if the phone is not actually connected to them.
The toggle in the Comm Manager is basically useless. It will connect automatically if you open your browser or other program that uses the data connection, even if the Data Connection is toggled "off". The only exception is if you are Airplane Mode.
If I remember correctly, you also need to toggle the Data Connection off in the Comm Manager, after you toggle "off" in NoData. I don't think NoData can shutdown a data connection that is already open. So I guess the bottom line is that you have to use BOTH the Comm Manager and NoData to toggle the data connection off and on.
radio reflash
So the odd thing is, no issue occured after I reflashed a different radio. Maybe it was the radio? But yes, I do have to use NoData and CommManager together. I had to soft reset after installing.
I'm running TMo stock 6.5 ROM. I have not subscribed to the data plan and use wifi for data connection.
But ever since I upgraded, every few minutes the "Data Connection" under the Communication tab is changes to ON by itself and the notification shows 3G or Edge depending on where I'm at.
Is there a way to figure which app is turning on the data connection? Is there a way to disable it? I suspect its the weather and location settings that does it, but don't know how to verify it.
Maybe Active sync
I have a Verizon G4 and have one major gripe.
At my workplace, the wifi is somewhat spotty and it's a guest network that requires authenticating (clicking an "i agree" button)
So my phone will, throughout the day, as it detects the "weak" signal, automatically turn off that network due to "unreliable internet connection".
Even as I'm back in an area with a strong signal, now my phone is ignoring that and stuck trying to use mobile network. I have to go into my network list and manually tell it to reconnect.
During all of this, wifi is enabled the entire time.
I see where others have had the same problem on other phones and have turned off "Smart Network Switch" and I even read where someone had done this on a LG G4 (not verizon).
So I'm thinking this is something Verizon removed. Anyone have any ideas?
Smart Network Switch is just a feature that checks for a "data" connection over wifi and switches to use Mobile Data if WiFi loses internet access.
I am not sure the G4 has this. When I am connected to WiFi with a bad signal, it will just send me a popup telling me the WiFi has no internet access and whether to use Mobile Data or not. The feature you are looking for is "Avoid bad WiFi Connections", which is the same thing with a different name. Just make sure that is OFF. That will force WiFi to use WiFi as the only connection.
And it sounds like your wireless network sucks and needs to be upgraded to a corporate solution.
Just FYI, in my WiFi > Advanced WiFi settings, I have everything unchecked + "Keep WiFi on when screen is off" = Yes.
Well "avoid bad Wi-Fi connections" is off. Read on another forum that the mobile version I think it was had the smart network option.
I have the same options as you except I also allow Wi-Fi scanning.
I have tried with that one both on and off and see the same behavior.
I never get a popup, it just ignores that wifi connection and used mobile data. When I look at my Wi-Fi list, it'll say something about unreliable internet connection in small text,on the Wi-Fi network that it disconnected from. Surely I'm not the only one seeing this.. :/
Beats me. Sounds like the Access point you are connecting to has a bad internet connection. What is happening is you are connected to the WiFi and it notices that the WiFi AP is either dropping internet connection (Google pings google servers to test connections) or bouncing.
In order to keep from losing a data connection, it seems to be switching to your cellular network.
I see this often because we install APs (I am a network engineer). I think your phone is trying to protect you and that is normal behavior. Here is another scenerio: In a hotel, wifi is always set to OPEN. If your phone automatically connects to the hotels network, you will lose a data connection because Hotels require you to "sign-in", just like most free wifi places do. The phone sees that your phones WiFi connection is not accessing the internet and making sure you are good.
I am not sure how often it "checks" the wifi for a good connection or if it ever does once it switches.
Just wondering if anyone else is having problems using internet while on a call. I will have LTE until I start a call at which point the phone drops to a h or h+ connection and refuses to do anything network related. When I look at the phone information menu it says LTE for voice and data, is there anyway to force voice to UMTS or something so I can leave the LTE open for data? I'm using cricket wireless, a at&t mnvo in the USA and I'm on viper is 7.1.2. I'm not provisioned for volte or wifi calling.
I also don't get any internet at all on HSPA. Never had a phone do this before.
Anyone else facing a problem of lost data connection during a call? It happens even even with wifi connection. I sometimes need to use the internet during a call... but the internet connection automatically disappears for the duration I'm on call. As soon as I end the call everything is normal.
When on LTE the phone automatically switch to 3G/UMTS during call (VoLTE is not supported by much providers yet).
During the switch if you're in a bad 3G area or with many people on your cell data connection is lost, the phone gives the priority to the call obviously. LTE is working very differently so that's why you can have a nice LTE data connection and without moving a ****ty UMTS data connection.
I've managed to browse web during my calls without issues on the 5T.
