Speaking with WiFi - MDA III, XDA III, PDA2k, 9090 General

Is there a program that is able to make phone calls with wifi without being connected to a wifi network ?

To use skype you have to be connected to a WiFi network but I want a program that doesn't wifi connection. I want to talk directly with wifi. I hope you understand me :/

Do you mean cellular internet? You can use Skype with that.

What you are saying is contraditory and confusing.
If you want to make voice calls through wifi, you need to be connected to wifi.
Probably you need to clear out what you actually want and explain in more details so we can help you.

Yes you are right, but my English is not very good. But I will try again. Normally to speak with Wifi you have ot turn it on then connect to a network and the use the program you want. But I want this. When i go to my village there is no Wifi networks. So I turn on my wifi and it doesn't find anything. Can i speak in this state - without wifi network, directly by Wifi.

When you say "speak with wifi" what do you mean ? Using a wifi network or speaking (voip such as Skype) through wifi ?

I think what the OP is asking is a way to make a call using wifi as the carrier vs GSM.
I guess in theory it's possible, as 802.11 is just a 'physical' layer, but I've never heard of it being used in such a manner.

VoIP is a protocol that rides on top of a networking protocol which rides on top of the physical layer.
I'm sure this isn't 100% correct, but I think it will get the point across.
Cell phone:
The stuff that lets you dial and talk <- application layer
The part that lets the phone talk to the cell towers <- network layer
The GSM frequency and carrier <- physical layer
VoIP:
The stuff that lets you dial and talk <- application layer
The part that lets the phone talk to other computers (TCP/IP)<- network layer
The ethernet cable/wireless network signal <- physical layer
What the OP was asking was if there was a way to use the wifi signal in place of the GSM frequency.

[QUESTION] 3g/internet during call

I wonder why it is not possible to access internet over 3g during ordinary gms call. With iphone one can access net, receive mails even when you are on call. I tried same with diamond but it never worked.
Anyone know why it is so?
PS: I did try searching for related questions in this forum before posting. If you guys find any related thread, please guide me so but dont start bashing right away
You have to have enabled 3g on your phone and be in a reception area that allows 3g

Works fine on my Diamond. Using data and voice simultaneously is dependant on some factors though, namely your device, the networks capabilities, your signal, and strangely enough, a tweak some users use on their devices.
There's a bit more info here: http://support.wmwifirouter.com/knowledge/KB0802013/, it might explain it a bit better.

[Q] My3G for android

is there an android app that makes the phone think you are on wifi when on 3g? with the new wifi calling coming i would like to be able to do it via 3g. is there a way to do this?
What in the world are you talking about? The wifi calling app will use your T-Mobile phone number and minutes, emulating your cell signal. Why would you want to emulate something that's emulating what you're trying to emulate with?
I hope you aren't asking about how to falsify your usage, but even if you are it isn't possible through T-Mobile's wifi calling app.
let me explain i want to know wether or not it is possible to make your phone think that its 3G/4G signal is wifi? there is an app that does for the iphone and i was wondering if we could get this also. i asked because if so would it be possible to do the wifi calling over the 3/4G network?
Again... why would you want to do this? If you have 3G/4G use your regular cell radio.
The WiFi calling isn't free... it uses your minutes on your plan. So essentially you would be hurting yourself twice... using minutes as well as eating away at your 5GB limit.
I can see that concept being useful in other situations, such as using skype or frostwire, or something to that effect over 3G, but the man has a point. You use your minutes and your data just to make a phone call? Plus you also get sub-par quality due to the large amount on extra latency introduced?
There are only two situations I can think of that WiFi calling over 3G may be useful. One, you have the [email protected] feature ($9.99/mo) on your plan, making WiFi calls free and unlimited, or two, you have a non-T-Mobile SIM in the phone, and you are, hypothetically, out of the country, and would like to use your cell phone as a cell phone, and not have to be near a WirelessAP.
Lol....wow

I was jsut using wifi calling as an example. it currently bugs me that we have frostwire working on the phone yet we need to have wifi active to use it. i was just wondering if doing something like that is possible? it would make my life a whole lot easier.

I saw a cracked Skype app that will call over 3G, but I'm not sure about frostwire.
Another benefit I could see, is that I think if you leave the wifi area you drop the call. But if it would treat the cell signal as still wifi you wouldn't drop the call.

Nope, cell handoff is the technology that UMA provides, and at a hardware level. The T-Mobile wifi calling app is a software solution and not true UMA, and is not capable of this.
Also if you want to use frostwire or skype or whatever over 3G, you will have to mod the app itself (if it is even possible, but it's more likely T-Mobile has a filter on this sort of traffic)

One example: NFL app. If you use 3G it won't let you play videos (probably because they can tell you're not on Verizon).
Apparently per the NFL app thread, it's only T-Mobile users that are getting no video over cell networks. I've seen multiple other carrier users say it works fine for them there. Which kinda sucks...

About my3g
Hi everyone, so the issue is why I need to simulate a wifi conection, well there several good reason, but the important one maybe it's the possibility of download app from the PlayStore that requare a wifi signal (my need for speed Shift for example), and everyone knows the 3g network it's faster the wifi, the app my3g it's famous for the iOS users so we where wating for solution.
Thanks
oh man, i wish there was a My 3G for android..... i cant believe guys cant figure out why it would be good to have as well? some apps, like iCam only work over wifi, but with my3g, i could view my webcams at home, from my iPhone, without a wifi connection. awesome.... and nettalk, a voip app that works on wifi, worked great on my 3g!
Anyone found a way yet ?
An app that could simulate a wifi connection would be really usefull ... My3g on iphone is great . Im also thinking about going back with apple . The limitless possibility of android are limited by what I think is way too much dev on ios and not enough on android . So ios have everything and we dont . I dont have internet at home but I have unlimited data on my cell . So with no wifi I cant backup my cell on the cloud because its wifi only . Many games like modern combat 4 doesnt allow to play on cellular data . And someday someone gonna work to crack the game instead of making a my3g equivalent and resolve the problem once and for all . I would pay for that and so would a lot of ppl .

It would be very useful. It doesn't matter what someone wants to use it for but what matters is they want to know if there is an app for this. The iPhone has 2 jailbroken apps for this so why doesn't android have it? Or do they have one?

Airplane mode + WiFi calling

Where I live there is -50 bars of cell service, so when WiFi calling drops it starts searching and absolutely murders my battery life. Is there anyway to hack the system to allow WiFi calling while in airplane mode? I've heard certain phones can do it. Are there any devs on here that have the know how? I know we have some very talented people in the community so I'm hopeful. It seems like it should be pretty easy because while on WiFi calling the cell radios get shut off and WiFi works in airplane mode, so?
I'm just not convinced WiFi calling will ever be more reliable and only getting 9-12 hours on a charge really sucks! Anyways, here's to hoping for a fix!
If you go to WiFi Calling Settings -> Conection Preferences -> WiFi Only.
I think that would do the trick.

^ Tried it out of curiosity because it would be useful to me, but that does not work.
I wonder if it would work if you used a program like Tasker to cut only the cell radios without explicitly entering "airplane mode". Although I'm not 100% sure that is possible or if some other work-around is needed.
Maybe there's something that can be added to the csc feature.xml? Not sure what it'd be but theres already these listed:
<CscFeature_Settings_Airplane_Wifi_Dependency>false</CscFeature_Settings_Airplane_Wifi_Dependency>
CscFeature_Web_Bool_StartWIFISettingInAirplaneMode>false</CscFeature_Web_Bool_StartWIFISettingInAirplaneMode>
You could check other devicrs that have wifi calling and see if theirs is listed. This may not even work, but could be worth a look.

Also, there's an app in the store called Bobsled Calling (also a Bobsled Messaging app) listed under T-Mobile top picks. Don't know how good it really is, but I was thinking bout giving it a shot on my old phone that has no cellular service at all.
One of the only ones I've seen where the people you call don't also have to have the app.
Maybe it'll allow you wifi calls under airplane mode?

You can try going to your Phone app and typing in *#*#4636#*#* -> Device information and then hit the 'Turn off radio' button. I used it before when Hurricane Sandy knocked out the cell towers and I was left with just random WiFi hotspots, but this was back on ICS. Though I don't see why it shouldn't work with JB.
If the code doesn't work, go to the Play Store and download an app called 'Phone info' (Author: [email protected]). The app should take you to the Testing menu.
Instead of constantly typing all those numbers (*#*#4636#*#*), download the app, Phone Info in the Play Store and there you go....

That app doesn't work because when WiFi calling is working the radio is idle. Service menu is a no go.
Sorry I didn't post it as a Q but I didn't have a clear question. I wanted to discuss the topic. I thought about yet where to post it before I did, thanks.
WiFi calling with Cellular Radio turned off
I am trying to accomplish the same thing but was approaching it from a different angle. The service menu idea doesn't work.
We are both trying to accomplish the same thing. Use WiFi calling while having the Cellular radio turned off. Airplane mode turns off all radios and you can re-enable the WiFi radio. However the Galaxy S III will not allow a call to be made while the phone is in airplane mode. This is a low level system issue and not related to the dialer (I tired three different dialers).
Does any body know of a way to do this??? PLEASE??? I'm leaving for Brazil in 4 days for a month and I would like to be able to do this in Brazil.
This is a copy from another posting:

I am trying to enable WiFi calling with the cellular radio turned off.
According to Samsung & T-Mobile the only official way to turn of the cellular radio is to enable Airplane mode.
Here is the procedure that I tried:
Enable Airplane Mode
Turn on WiFi
Connect to a functioning WiFi hotspot
Enable WiFi Calling
Wait for the WiFi Calling Icon to appear in the status bar
Make a WiFi call
At this point the dialer sits at the dialing screen for more than 10 minutes (I bailed at 10 minutes). As soon as I abort the dialing attempt a dialog box pops up saying you cannot make a call while in Airplane mode.
Is there any way to completely disable the cellular radio without putting the phone in Airplane Mode?
Is there an app that will do this?
Is there a hidden that will do this?
Please don't use bandwidth by asking why I want to do this or suggesting that I use Skype or some other app. My goal is to be able to make and receive VOIP calls while the cellular radio is completely disabled.
Thank you for your help...

I think maybe the phone HAS to ping a cell tower in order to make WiFi calling work. For your purposes just set the WiFi calling connection preference to WiFi only.

I have zero reception at my house and wifi calling works.
Setting it to "WIFI only" doesn't allow it to work the way that's wanted - it just tells the phone to only make calls over WIFI - but that doesn't open up the ability to do so when the radios are off. From what is described I agree that this sounds like a conflict with the low-level integration.
Did anyone try that Bobsled app I mentioned earlier?
It claims that I could put it on a tablet or my old phone that has no sim/data, and it would work.
If it were to work is that something that could get you by for a while? I understand not wanting to go 3rd party, but it could be the only option for now. It is a tmobile app btw.

There's also a Bobsled messaging app. Pretty sure its the same deal and works via wifi.
Also, I could've sworn it said that you have the option of using your current cell number. Maybe I'm mixed up on it...
Anyway, its just a suggestion for looking at. I have no idea how good it really is... just don't have many other ideas for you guys at this point.
I wonder if there could be a build.prop value that would disable cellular only. Or set its scan frequency like you can do for wifi.

I have done some more research.
I was able to turn off just my cellular radio by using the phone info application to enter the service menu (Phone Info App->Device Information, scroll down and select Turn off radio).
With the cellular radio turned off I tried to enable Wifi Calling (Settings->More Settings->W-Fi Calling).
The phone says "enabling", turns on the cellular radio (without any messaging saying that it is doing this) and then says "Ready for Calls".
I also tried enabling WiFi Calling first and then turning off the cellular radio (using the method outlined above). But the cellular radio would not turn off as long as WiFi calling is enabled.
I don't know if this is a bug or a "feature" but for WiFi Calling to work on the T-Mobile SGH-T999 (4.0.4 Firmware) the cellular radio must be enabled. Though I'm sure T-Mobile has a reason for this the logic of it escapes me. WiFi calling should not need the cellular radio for any reason. I use Skype all the time and it doesn't need cellular service to operate on WiFi.
If anybody out there knows how I can make and receive phone calls using my regular cell phone number exclusively via WiFi (with the cellular radio disabled) please let me know. Many thanks to the person who figures this out
As long as you are connected to Wi-Fi, with Wi-Fi calling activated (blue icon showing), it should automatically disable the cellular radio. If you are connected to Wi-Fi, but no blue Wi-Fi calling icon, then it will turn on cell radio and start searching for towers.

Duh.. the reason to use it in airplane mode for me is that WiFi calling disconnects every few minutes and when the cell radio is searching since I have 0 coverage it absolutely kills my battery.

Sorry but you're not making any sense. You're complaining about your phone's search for cell towers killing your battery because your Wi-Fi calling keeps disconnecting? Let's say you find a way to disable your cell connection. Your Wi-Fi calling still keeps disconnecting and you still can't receive or place calls. What's the point? Longer lasting "iPod"? Maybe start looking for a way to fix your Wi-Fi calling problem would be a better solution, ie. Flashing a different ROM until you find something more stable. Duh!

These are the following options available (all of these options have the cellular radio enabled and working at all times):
1. Make calls using the cellular network only - WiFi Calling disabled.
2. Wi-Fi Preferred - Make calls using WiFi Calling if a valid WiFi network is available and connected. Cellular network calls are made when a WiFi network is not available.
2. WiFi Only - Makes only WiFi calls. Cellular calls are not made when a WiFi network is not available. Note: This does NOT disable the cellular radio.
3. Cellular Preferred - Makes cellular network calls are made if a cellular network is available. WiFi calls are made if a cellular network is not available and a WiFi network is available and connected.
When enabling WiFi Calling the cellular radio is briefly disabled and then re-enabled..

I never heard of any such thing unless perhaps you are speaking of
some 3rd part software app and not the built-in wifi calling feature
which is exclusive to people using the Tmobile network with a
Tmobile M919 cell phone and sim card.
How can anyone improve wifi calling when it works just as perfect
as normal cellular calling?
No one I know of can tell any difference between wifi calling and the
default cellular calling unless someone has a very bad or intermittent
wifi connection.
Good luck finding a special code!
I too have never heard of such thing. From my understanding, Wifi-Calling is as good as your wifi to some degree, it levels off somewhere.
Haven't heard of it either and I've been using wifi calling since nexus one day.

I've been using it since the Blackberry 8900 days. It was called UMS I believe and it was very good at handing off from WiFi to cell during an active call.
The only way of improving WiFi calling come in when you have an issue with your WiFi or rather, your ISP. Then again, that's still not an issue with the function but your ISP or WiFi setup.

This is probably not what you were looking for but if you turn off wifi power save mode it will make your connection more reliable. (*#0011#) click bottom left button and hit wifi. Turn off power save. It holds a better wifi signal and is more dependable. Hope that helps somebody.

Hopefully this has some effect. I just turned it off.
I too have never heard of a special code or method to improve WiFi Calling. Are you talking about in regards to more functions, or improve your signal strength so that it works even when your signal is poor?
Quite honestly if someone was able to allow WiFi Calling to bypass the "poor signal" message when you only have one bar of signal, that would be awesome. Though there is probably more to it than that. Calls maybe need more signal, but not texts. Calls would therefore need 2+ bars, whilst texting only needs 1+. Would be cool to see that happen but it doesn't seem possible. My specific area at work I can only achieve 1 signal bar of the guest network in some spots unless I go by the door and of course no sign of mobile data is even existent in there, hence why I use WiFi Calling. So it'd be nice if I was able to send texts with 1 bar of WiFi. :crying:
But if anybody has any info about this "code" thingy, please post! I'm all for looking to improve it.
Service codes?
Sounds like the OP is looking for the service codes you input in the dialer. I don't recall anything in there that would affect wifi calling though.

Is there monitoring software to monitor everything sent to towers?

The phone is constantly connected to cell towers which can triangulate your location.
Is there some sort of root software which would completely intercept and monitor all traffic between you and cell towers? One that would tell you what is being sent and received? And tell you if the GPS is really off.
What about forcing the phone to connect to only one tower?

The idea is to have the phone usable...
Monitoring is done mainly by the towers not the phone. Theres no way to stop your carrier from tracking your phones movements around its network.
Your other worries have nothing to do with the carrier. If GPS is off it will show as off unless your phone is compromised, location data will only be sent if you have location reporting on (this does not affect mobile towers from recording device connections).
You could monitor traffic on your phone with something like tcpdump and analyse the data, but a better way would be don't use apps you don't trust.
What exactly are you worried about?

So the protocol is such that you don't address any particular tower but rather just broadcast and that's how they are able to triangulate you?
What about turning the RF radio off and on without taking out the SIM card, know any app to do that? (Assume that I don't need to take calls only place them. The goal being to minimize tracking/interaction with carrier.)
Also can you explain to me or link me to how this cellular protocol knows where to route calls to you? If there is a keepalive signal how frequently is it transmitted? What if you turn off all broadcast but not the radio itself, will the tower still try to route calls to your last known location and if you are there you would be able to take them?

So the protocol is such that you don't address any particular tower but rather just broadcast and that's how they are able to triangulate you?

If you turn the radio off it wont connect to a tower but you also cant use your phone.
Theres maybe a little misunderstanding when it comes to how mobile networks work. There no different from computer networks, and just like computer networks mobile networks track where devices are located on the network. It isn't miserableness for malicious reasons, keeping track of where devices are located on the network helps maintain the networks performance and fix problems. The side effect of mobile devices is there are almost always attached to a body and inadvertently allow the potential for a person to be tracked within a margin of error.
When the radio is on (and im not an expert on this) the phone will periodically contact the mobile tower as far as i know, and does this to make sure your connected to the right tower for it to route traffic to your phone or move you to a tower with a better signal.
If your really bothered by it, put it in air plane mode and use wifi only with encrypted calls. But wifi can still be used to approximate a location just like any other means of communication.
It would be good to know your goal? If it is simply to not be tracked your _only_ option is to not use a mobile phone. People do that, for that exact reason.

By not use it do you mean it won't even boot properly or I simply won't be able to place or receive calls?
If the latter, I would still like to know how. Is there an app for that?

Put it in airplane mode. By not use I mean no phone calls or internet.

Airplane mode disables WiFi as well, this won't do.
Surely there is a root app that can toggle the cellular RF radio?

You can turn on wifi after you put airplane mode on, but it defeats the purpose. You can be tracked via wifi.
Non of this also considers if the phone is compromised or if it collects data and sends it once it is connected.

WiFi tracking is impractical. I'm only interested in disabling the cellular network unless I want to place calls.

Actually WiFi can be even more beneficial. It's not dependant on the phone network meaning the tracking information can be sent anywhere in the world, you can send more information than just mobile tower beacons, tracking data can be recorded and sent later when a connection is made either though WiFi or mobile data. Its not dependant on your phone either, your phone sends out a WiFi beacon periodically looking for wireless networks, any WiFi AP within range will pick up this broadcast from your phone and potentially record it ( it is identifiable), additionally your phone broadcasts all WiFi APs you've connected to to see if it can reconnect to them, these can be recorded and used to predict and track movements as well.
You still haven't said what the purpose of this is and im starting to think your just trolling. Turning off the mobile radio is practically pointless if you're connected by any other means.
