Can you run Wifi and 3G/HSDPA connections simultaneously?

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.

if WiFi is on, and 3G is on
the phone automatically uses WiFi first

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?

[Q] Best (Fastest?) Tether (USB and WIFI) (Root and Not)?

Just rooted my Droid X (Thanks XDA!) and am using "Wireless Tether" but only allows for unsecure (no password) connections it seems. Wondering what better options are out there for the fastest connection? I'm a MS consultant and need to VPN for work on the road, connections are weak-sauce to say the least. Wondering what your experiences have been USB vs WIFI for best speeds?

Go with the TBH 3G hotspot "fix" easy to do and works great with vpn. Speed is the same between Wireless Tether and the 3G app. Never used any usb tether on it so no input.

To turn on the password protection for Wireless Tether. open up the app>settings>Enable Wifi-Encryption.

Thanks, will research TBH.. I know how to enable the encryption but it doesn't connect with it. Thanks.

speaking of wireless tether..
mine doesnt seem to actually close the connection. data stops and the phone says everything is turned off, but other devices can still see the Ad-Hoc connection (devices that were turned on after i turned it off)
so obviously my battery lifes tanks after this until i restart.
any thoughts?

Dnak for wireless tether try changing the network name(ssn) to something different. If you've already done that then try putting it back to default (AndroidTether).
Also look at the "access control" settings. There you can allow/deny connections. That can be enabled and used as a security measure. Mine sometimes blocks my ip for some reason, just have to "allow" it again.
Or try going to settings > apps > manage apps > wireless tether, and force stop(if needed), clear cache and CLEAR DATA. Clear data is the important part. Hope that helps

Will give that a whirl, ty man.

Need info, how to disable data

Hi,
I want to give my phone (Nexus S) to my son and switch to a family plan with data but I dont want him to have access to the 3G, I just want him to use wi-fi to connect to the Internet. Is there a way to disable the data and keep the wi-fi and SMS active? Maybe changing the APN setting to a non-working one. I dont want to just unclick the data option because you know that he will find the setting and reactivate it
Thanks.

I use APNdroid and I surf only by wifi. I dont have data plan, too

You can always delete the APNs in Wireless and Networks => Mobile Networks => Access Point Names.
But if he's cunning enough he can easily add them back.
Then again, can't you just ask Rogers to disable data for his SIM-card?

Just go to Menu > Settings > Wireless & network settings > Mobile network settings > Access Point Names > "current apn", now change the following.
APN > put a hash "#" and a couple of other characters at the end
MMSC > put a hash "#" and a couple of other characters at the end
APN type > put a hash "#" and a couple of other characters at the end
The phone should no longer connect to the mobile network, eg: 3G, 2G etc.

I think SMS need data on.

No, it doesn't.
Greetz

Be careful, at least in Germany, some carrier allow internet access regardless of faulty APNs
I'd just call the carrier and ask them to deactivate mobile internet for that sim card, this also avoids trouble if there are ever costs for mobile internet on your bill.

I checked with Rogers and they cant disable the data for the phone since its part of a family plan Would have been too easy.
I will do some check with APN to see if everything work except 3G when I put wrong data in setting.
Thanks all

I need to read.

I disable mobile data everyday to save battery. SMS and calling still work and wifi still connects. After I'm out of range of my router just cell signal no data.
Go to settings -> wireless and networks -> mobile networks
Simply uncheck data enabled

[Q] Smart Actions to automatically disable mobile data when connected to wifi?

On other forums, people have suggested setting up a smart action to automatically turn off mobile data when connected to a wifi connection. However, my Razr M does not appear to give me that option.
I am able to set an action to turn on wifi, and to turn off mobile data when I am at home (using my home location as the trigger and turning wifi on, and turning mobile data off as an action).
However, when I try to set wifi network as a trigger, the "set mobile data" action is greyed out, and I am unable to select it. This is on version 4.2.2.3.0.
Am I missing something here, or is what I am trying to do not possible?

Is there a reason you need to? Android *should* shut data off for any apps that don't specifically request mobile data (VZW's suite comes to mind...)

Two reasons: 1) I am on a shared data plan via work, so I want to be mindful of my data use, and 2) it it my understanding that connecting to wifi uses less battery than being constantly connected to 4g.

When Wifi is available and your phone is connected, automatically 4g is off and wifi is used... I don't see the point of using smart actions for this.

Thanks, I did not realize this.
The reason I ask is because I saw a number of sites that discussed turning mobile data off when connected to wifi. See here and here

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.
