Can you run Wifi and 3G/HSDPA connections simultaneously? - Galaxy S I9000 General

So the if the phone connects over wifi it drops the data connection that might've been present on your phone network connection. Is it possible to configure your phone to maintain both wifi and 3G/HSDPA connections at the same time?
I require this because my operator provided (H3G UK network) Skype application only runs on 3G and I have to keep turning off wifi for it to work.

Funny, I find this feature great!! With my WM phones I never knew if it was using wifi or my data connection....even if you can do this how do you make one app use one connection over the other?

You can try droid wall, and configure it to block wifi for skype, it may solve your issue.

Hmm, doesn't sound like that will work, because the phone has already dropped the phone network data connection as soon as I get back home onto my home wifi network (due to prioritisation?) I want the phone to maintain both so I can receive incoming Skype calls at home with fiddling with my phone. I understand why the phone does it and it is sensible for it to do so in most cases, but just not for my usage requirements!
Is it a software/hardware limitation that wifi and phone network data connections can't be open at the same time?

Install Nimbuzz. It supports Skype without that bulls**t restriction. It doesn't support group chats though.

I lose the "H" or "3G" notifier when the phone connects to wifi, that's why it looks like it's purposesly dropping the data connection once it picks up my wifi, I can't see a way to maintain both simultaneously.
I'm using "Skype for 3" provided by my network, it has special integration on the 3 network which allows me unlimited Skype usage (inbound and outbound) without it eating into my data plan. So with this benefit I don't really want to use an alternative app.
I want to keep Skype running all the time so I can receive calls on it, but once I get home, the wifi kills the "H"/"3G" connection, which means my Skype can't receive calls.

the icon isn't there but i think the data (H / 3G) is still running in the background, incase your Wifi fails.
wifi is the... PREFERRED network?
have you tried getting your friend to call you via skype while you're on wifi?

Wifi and 3G simultaneously?

I just noticed a potential issue. When I enable Wifi, it appears to disable 3G.
The 3G symbol disappears. Is it possible to have Wifi and 3G on at the same time?
How is that an issue? Every android phone I've owned (G1, MT3G, N1, Droid, Incredible, Vibrant) does exactly what you're talking about when you turn on WiFi. If you're on wifi, you dont need 3G.
... and I believe this option is set by default; if you are on WiFi and the screen goes to sleep the WiFi will be disconnected and the cellular data re-enabled.
If you're concerned about making phone calls, don't be. You still get phone reception just as if you weren't on the wifi. If you want 2 data streams, that's not gonna work, though I have no idea why you would need that.
I've switched from wifi to 3g and back to wifi again while on hold in a call and sending emails and browsing. This phone is awesome. Off topic, sorry

3G Mobile Hotspot + Bluetooth : Can you do both?

Im trying to use the 3G hotspot, and GPS2BT to allow my tablet to access maps with data and GPS from my droid X.
But everytime I turn on the hotspot it shuts down BT, and if I re-enable it, the BT turns off 3g hotspot.
Is it possible to use both, if not, why? To much power draw using 3 radios??
You cannot use 3G + WiFi + Bluetooth simultaneously. Something to do with radio and antenna sharing, I believe.

The reason it wont work I believe is a result of verizon's setup. When you turn on the hotspot app, it pulls your data connection and changes your dun settings to allow the wireless adaptor to broadcast a wireless signal. You are no longer receiving data as if you were trying to.access information though an application.
I think natf is right. When you toggle bluetooth, I think it kills any other "radio" connectivity.

try making a call on a BT headset with wifi enabled, then go to a web page... its ... interesting.
Ah ok - Damn. I was hoping to share my wifi with my android and then use BT to get GPS.
Guess its one or the other.
I dont think i can do BT PAN + any other bt service can you? then i could do both with BT..

I was under the impression that you can't call and surf at the same time with Verizon.

You can surf when WiFi is connected. Although I could do both over 1x with my Touch Pro2.

[Q] how to make sure that i am on wifi or 3g

Bro and sis, is there a way to make sure whether i am connected via wifi or 3g? Cuz my 3g dataplan is not unlimited.
Thanks.
Hold the power button down until the device option screen pops up, the same screen that turns it off. You'll see a Data network mode. Select that so that it shows Data network mode deactivated. Now 3g is off for sure.
Sent from my DROIDX using XDA App
you can also use widget or personally go to setting to turn off 3g
but somehow, every time my wifi is on, 3g is automatically off
u wont see the symbol on notification bar anymore
thanks bros, nice method.
I've had issues with wifi randomly dropping. Some times I wont notice and the 3g handles my traffic even though I don't want it to due to only getting the 1gb plan. With fully deactivating the 3g data I know when I drop my wifi and am ensured that I've turned my tab into a wifi only device.

The tab uses wifi first when available, and puts the cellular modem to sleep.

[Q] Overseas Internet Calling?

Heading to Afghanistan this week. Does anyone know if wi-fi calling works there and will I be charged roaming fees? If connected to wi-fi, will 3rd party messaging apps work? How about skype, tango, qik or gtalk? Any info is appreciated.
The problem with using wifi calling is you can't connect / use when in airplane mode with wifi turned on. You have to have sim card on with wifi, which I was told may or may not incur roaming charges. BUT any call you make with wifi calling on will be like you making a call from the states.
When I went to a foreign country, I use tango, what's app with wifi, and airplane mode. That is completely free.

I was in Europe earlier this year and it worked great for me. I had my T-mo SIM in, mobile network disabled, WiFi calling app set to WiFi calls only and it was working great on all WiFi networks I connected except one - the modems of one of the local DSL ISPs seemed to have ports used by the WiFi calling closed so I was getting connection errors in the WiFi calling app. But this was one single provider and I guess if I'd researched it I could have fixed it in the modem settings.
I don't know anything about the other options.
Skype and Gtalk work fine on WiFi. If your communication can be done at specific hours (which I presume is correct) - Skype and Gtalk are good options, and even video calling on them is good enough and doesn't require much bandwidth usage.

Switch back to cellular when wifi has no internet, but keep wifi connected

tl;dr: When my phone (Sony Xperia Z5 compact, Android 6) connects to a wifi with no internet, I want to use the local network on the wifi but use the internet from my mobile data. Instead what happens mobile data doesn't switch back on while connected to wifi with no internet.
I have been trying to find a solution for this since forever. My camera creates a local wifi connection which I can connect to to view the camera as well as controlling it. The downside is that while connected to this network my cellular data gets switched off, despite this wifi network not having any internet. So while using my camera I have no way to access the internet. It wasn't a huge problem up until recently when the app I use is introducing livestreaming. I really want to use it but I am unable to find any way how to keep my phone connected to this wifi network (and being able to use it), while any internet data goes over 4G. I am using android 6.0.1. I am quite sure I was able to do this on my previous phone with an older Android version but I cannot find said option (smart network switch or something?) anymore in the wifi settings. Nor any recent similar topics with people with the same question? Anyone that knows more about this?
My phone is rooted. If I need to do any system changes I can do that.
I didnt get what you were trying saying.Do you know that you cant use mobile data and wifi simultaneously unless your device is rooted.If your phone is rooted then try using "download booster"

Err, sorry, lol. I have wifi network that has no internet, just a local network. I'd like to be connected to that wifi network AND be able to use internet over my mobile data both at the same time. As it is right now, my mobile data gets disabled even when the wifi network has no internet access.
I have talked to two friends of mine about it and both say this is already possible in Android. One friend sent me a screenshot of an option he has in his wifi settings called 'Switch to mobile data' which gets enabled when the wifi network has no internet. My other friend said he doesn't have this option but claims it has been a default feature of Android since lollipop. He tested it on his phone and indeed it works as expected. Both have an unrooted phone with stock Android. So now there is me with my brand new phone and Android 6 and I can't find this option nor does it seem to do what I want by default. I'm confused.
As I mentioned, my phone is rooted so if there is a way to turn this feature on using root, I can totally do that if someone knows how.
As i said try using "Download Booster" It allows you to use wifi and mobile data at the same time just google it.

That appears to be just a download manager if I am correct? I don't need to download anything. I just want to be able to use my existing apps to use my mobile internet when I am connected to wifi (that has no internet).
This is the exactly the thing I'm after. Screenshot from my friend's phone (LG G4 with Android 6.0): (*link removed). My other friend who also has this functionality working has a Nexus 5 with Android 6.0.1.
* Forum doesn't let me post screenshots.. But basically in his wifi settings he has an option called "Switch to mobile data". The box says "Internet unavailable via connected Wi-Fi. Stay connected to Wi-Fi, but use mobile data. Data charges may apply."
Again, I have Sony Xperia Z5 compact with Android 6.0.1 and I can't find this. Have I bought the wrong phone or is it fixable? At this point I am more than happy to even take a custom rom route.
You cannot use wifi and internet at the same time as they are completely different hardware components, using different air waves, so there's no conflicts between them. Better use internet through your wifi or use bluetooth tethering.As for the "switch to mobile data option" it disconnectes you from your wifi if it has no internet and connects you to your mobile data so it doesnt lets you use your wifi and mobile data at the same time

It actually clearly mentions that it keeps connected to the wifi. He tested it and indeed he could use the local network on the wifi side and use the internet through his mobile data simultaneously. Both friends haven't rooted their phones or anything. This is just a default functionality for them. I have now tested it also on my older phones (Oneplus One and HTC One M8) and all phones can't have both connections open at the same time.
This wifi network is created by my camera by the way and I can't change much about it. The DJI drone I control does the same thing. When I am connected to the camera or drone I lose my mobile internet connection.
I don't have any other device that has access to internet here. We don't have cabled internet, only mobile internet.
Interestingly, in the developers options there is an option called "Mobile data always active" ("Always keep mobile data active, even when Wi-Fi is active"). I've tried it many times, rebooted my phone but this doesn't actually do anything. Even with this option on when wifi is connected the mobile data gets turned off.
This is beyond annoying!
I too have struggled to find a solution to this problem. I do not have a WAN connection to my home network. It is LAN only. I have four PC's, three Sonos speakers, two hdhomerun TV tuners, and various hand held devices that all use the LAN. All I want to do is be able to use my Moto X Pure to control Sonos and file sync to my LAN via wifi and simultaneously use mobile data for WAN stuff. I know the mobile connection is active with wifi enabled because I can see it when running if config, up route show etc... I am trying to learn about the routing tables to see if I can fix this myself. I love my android devices and am loyal, but this is beyond dumb! Any suggestions????
How to fix for android
okay so for anyone who doesnt know still go into the about phone option in your phone settings, then click on kernel version, build model, etc til one pops up with a flash notification saying click so many more times and youll become a dev. once you done that go into the developer menu and scroll too wifi assist or force mobile data upon wifi connection. exit out , open your app , bobs your uncle
Thank you for the answer.
I tried with my Huawei but it doesn't work. Could you tell with which phone you made it work ? Thank you !!
Ok here we go, after 12 years this my first post.
Above suggestions related with developer options nothing to do with OPs requirement. Those option only allows the device rapidly switch to mobile data when the WiFi signal gets weak. Since you always close to your DSLR camera it solves nothing because WiFi signal is always strong.
Root cause of the problem is you can not have 2 default gateways (i.e. router address) for your networks in any operating system (Actually you can but you have to set static routes, which is a pain in the ass for regular users)
iOS handles this in a very simple way. Set your wifi connection to static IP address instead of DHCP and leave your default gateway or router address blank. Viola you can have 3G/LTE data while you connected your camera and now you can sent your downloaded pictures via Whatapp while you still connected to your camera via WiFi. (In my case Panasonic Lumix)
I stumbled upon this thread via Google since I needed the same thing now with Android. But iOS way failed. Actually I am shocked that you cannot leave WiFi Gateway address blank in Androdid 8.0! Save button grays out if you leave it blank. This is really weird. At least with Galaxy S8 Duos with Android 8.0
So anybody know how to setup a WiFi network without a default gateway, please share.
Is this phone specific or something? Never had that happen, I have no problem with wifi being on without internet and using cell data.
I don't think the UI really exposes anything like it directly but you can technically have multiple gateways; it's not something your average user will understand (policy routing)..
Having said that, if you're attached to an AP you should at least see a /24 route out your wireless interface (standard dhcp lease). It's quite common for the AP to have client isolation but are you sure you're not using something like Wifi Direct or even adhoc?
Similar Experience
I have been through this experience long ago. All I did was to sell the phone and bought a new one.
