[Q] Receiving calls while using wifi - GT540 Optimus General

I can receive calls when the wifi is off, when I turn it on it can't receive calls any more. The wifi works fine and I can use the internet. It shows 3g signal but not the H that shows it is connected to mobile data and all calls just go to voicemail. When I turn the wifi off the wifi data connects straight away and I can receive calls again.
Is there any way to fix this?
Thanks
If it helps I am using the latest Carphone warehouse 2.1 rom.

Using data connection blocks calls?

I've noticed that whenever I use the HSDPA connection heavily, all incoming calls get diverted to the voicemail. Any workaround for this?
I'm gonna bump this as I have the same problem

Drops 3G connection to connect to internet

I have an orange HD unlocked phone that I am using on Vodafone UK.
Even with a good 3G signal the phone will close the 3G connection for any kind of data transfers.
If I am sent an MMS while in 3G coverage I am prompted that it needs to drop the connection and make a new one to be able to recieve the message.
Any idea's whats wrong.
I have used the Touch Pro settings as Vodafone do not have specific settings for this phone.
mine does that too it's because the phone company use a different apn for internet and mms
so basically I may live in a 3G area but I can never use it.
same problem here, its actually verry annoying because my while using wifi, and browsing inet i dont receave any sms or mms or call, for everyone my phone is like offline, then sometimes wifi drps and im starting to receave all sms togeter and in the same time wifi turns off and browser starts using gprs instead wifi even if wifi is reconnected, and then im starting to pay for my proveder... sux.

Incoming calls lost after some time when using data connection (3G/HSDPA)

Hi all,
I've got my HD 2 for a week now and everything seems to be working fine, except for a very important bit: the phone.
When I'm connected to the network with a data connection, incoming calls are not possible after some time. The caller just gets a busy signal or my voicemail. This also happens when I haven't been actively using the connection for some time. Calling is also impossible most of the times this occurs, very annoying! Anyone else got this problem? It only happens when a data connection is present, under phone only use there is no issue.
When you say "data connection" do you mean Bluetooth, USB, or HSDPA/3G etc?
I haven't noticed this myself while connected to HSDPA...must check it out.
It only happens when I'm using 3G/HSDPA.
True
I have same problem.
Sometimes the call completely lost and sometimes the message "cannot dial for ...." pops up.
I think it could be connected to network itself ...

[Q] Loss of mobile data connectivity - AT&T

It happened 4 times on my Note 3 in the last 10 days. I'm home or at work under wifi. Go out and try to use mobile data and I get an error message that I have no connection. Yet my LTE signal shows 50% and above in signal strength. I tried to turn on airplane mode to turn it off to force my phone to latch onto the closest cell tower and it's still doesn't fix the issue. If it happens while I try to upload some files, I check my email or try to browse the web and it confirms that I have no working connection to the web. I end up rebooting my phone and it fixes the issue. It's as if the phone is still looking for my wifi connection and "forgets" to switch to cellular connection once I leave the building. I know there is a setting under wifi that says to auto switch between wifi and mobile network but it doesn't seem to make a difference.

Losing cellular connection (No text/calls received)

Several times a day, my phone goes into "silently lost connection" state. When it's in this state, the WiFi internet works fine, mobile internet works, phone still shows good signal bar. Basically, you have no way of knowing something is wrong with your phone, everything is as it should be.
However, in this state, I don't receive any TEXTS or CALLS. If someone calls, it goes straight to my voicemail. If someone sends a text, it goes on my "texts to receive" backlog or something.
The only fix is, go on airplane mode on/off. Then I get the connection back, texts in the backlog starts coming in, calls are received, etc.
My phone is SM-G935F (Android: 7.0, Baseband: G935FXXU2DRB6). I'm on T-Mobile network. I've tried a connection booster app that re-connects to mobile internet network or something, but that's not the problem because I can access the internet at all times, so that didn't work.
Does any know what's going on? Any idea for a solution? Maybe an app that turns airplane mode off and on every 10 minutes or something?
