Changing the android mobile data connection string. - General Questions and Answers

Hello All,
For older phones you use to be able to access the mobile data connection strings that tells the phone how to connect to the network and initiate a mobile data connection for ie. allowing you phone to brows the internet over a mobile data carrier and not Wi-Fi.
I hope I've explained that well.
What I want to know is if there is a section in an android phone, maybe the developers section, that I can change so that the mobile data portion of the phone will not be able to connect. I'm not looking for the normal data on/off in the settings as that can be changed at will, this would be something that not just anyone would be able to access to change. I do have a programming background so I should understand what your responses are but just need some direction.
I'm not quite sure where to put this so I thought this place would be good but let me know if it is not.
Thank you in advance.

Any way of knowing if data is coming through 3G or WiFi?

Pretty self explanatory this one - is there any way of knowing whether your mobile internet connection (3G) or WiFi is being used in, for example, a browser session? Just don't want to make the mistake of looking at YouTube on the phone, meaning to use the home WiFi, and end up using my 3G by accident, and paying through the nose for extra feed.

The icons on your task bar should indicate if you have a active data connection.
Or, you can use Spb Wireless Monitor (which you need to purchase). It produces reports telling you which software uses which connections and the amount of data transferred.
In a discussion I had with HTC Tech Support, they told me that wifi, when enabled, over-rides the cellular data. I'm not sure if this just applies to the settings or always. Hopefully, someone can provide a definitive answer.
Yes that is correct, if WIFI is enabled you WILL NOT have a cellular data connection.
Umm. There is a wifi icon in the taskbar o.o and a signal icon also.....whichever is there means it's active and if wifi is there, your data will not be active, only wifi.
What all you are saying is true but some applications still use the data network even if wifi is turned on and connected it seems. I have the same issue(i don't have a data plan with my fuze since my college has wifi everywhere). But things like weather and other native apps on the phone will just turn on the 3g network and stat using data instead of wifi.
if a device is transfering data over gprs/3g whatever
it show arrows moving in the signal str icon
otherwise it use wifi
Applications can choose to use a certain connection if they are programmed to do so, windows only gives each one a type of 'ranking', the fastest connection having the highest ranking and being the one an application is to use by default, but the application can override this and choose whatever connection it likes. This ranking is called the "Interface Metric" if you'd like to learn more about it.
There's an HTC program called 'bytecounter' that monitors the SMDx: ports in the system, which are the ports the system uses for data.. in bytecounter you will see the values increase if an application is using data over cellular network. let me know if you'd like me to upload it.

Well that wasn't particularly helpful. I too have made the same assumption, but the question asked if there was any way to make sure.

Well that was the kind of answer I was looking for, and is particularly pertinent in my case, as my connection through my mobile provider is about as fast (or maybe even faster) than my fixed line connection at home. A rather bizarre situation, but such is the advancement of Australian broadband infrastructure.
The last couple of times I have used it, I have taken to turning off the phone connection so that only WiFi is running, and then using the internet. It would be good if you can upload the byetcounter program, seems like a free (?) version of the software programatix mentioned.
Here ya go!
Maybe this is just me, but when I try to unzip that file, nothing comes up....?
lol, i always forget to remove the hidden attribute.. let me go ahead and fix that..
Edit: fixed
Newer Windows Live (including the one that come with Touch Pro) will always dial-up the 3G/GPRS connection when checking for email in Messaging. But if you are checking in Windows Live, most of the time it doesn't dial-up but sometimes, it does.
So far that is the only program that I know of behaves like this. I contacted Microsoft regarding this and they keep asking me to contact my celular provider for help. In other word, they are not helping (or do not understand the problem).
Anyway I solved the problem by changing the Connections setting to "My Work Network" for Internet. The catch is, if I really want to use 3G/GPRS, I'll have to change the setting to my celular 3G/GPRS connection.
Or you could use the nodata application from modaco and disable whenever you like the cellular 3g connection just to be sure you are using wifi.When you are away from wifi networks you can in a matter of 2 clicks reenable the cellular 3g connection...

can't download using mobile network

Hello all.
My first post here, even though I have had a lot of benefit from using this forum.
I have just updated my HTC magic with this ROM http://forum.xda-developers.com/showthread.php?t=552274
and now I canøt connect to the mobile network anymore. Whenever I try to refresh the weather or create my email account, I get the following message: This application requires network access. Enable data connection or Wi-Fi to download data.
I currently do nt have access to a wi-fi network, so what do I do?
FYI I have no problem calling my phone, so I must be connected to the network.
Hope anyone can help.
Kind regards

Guess you have to manually set your APN settings. Look for info at your providers homepage.
That worked perfectly. Thank you very much.

[Q] Disable Data Connection

I don't have a WP7 device yet, but I am considering getting one. I am looking to disable all data (over the network) before actually starting to use the phone.
- Specifically, I was wondering how the network/connection settings were configured on a STOCK WP7 phone (in comparison to, say, WM6.5). The reason I want to know this is because I want to disable data (over the network) at all times... and I want to do this prior to actually using the phone (with my SIM card in it).
In WM6.5 (and earlier), the network/connection settings allowed you to create a "dummy" network that the phone would connect to (instead of allowing the automatic connection to the data network). All you had to do was tell the phone to connect to a network that didn't exist (so that it wouldn't ever connect to the data network)... thus, no data would ever be used because the phone would never connect to a data network.
Do the WP7 network/connection settings allow you to do something like that? And, are you able to access these settings before putting a SIM card in the phone?
- Also, I have seen a few threads mention that there is a button/option that disables network data... if so, does this actually work? As in, does it completely shut off access to the data network?
Obviously, I would prefer to create the "dummy" network if possible, because I know that it will NEVER connect (I used this method on a Touch Pro 2; it would also say the network was "offline" whenever I accidentally tried to use the internet or something without the WIFI being on; this is exactly what I want).
Thank you for your help. Like I said, I don't have a WP7 device yet (which is why I'm asking these questions)... but I hope to get one soon if the data connection can be disabled.
Menu>Settings>Mobile network>Transmission data (or Data transmission, I have Polish language and I don't know how that called in English ROM) - off.
^ Thank you for that... so that confirms that there is a button/option to turn the data off.
But, I am still wondering if there is a way to create a network that the phone will never connect to... in WM6.5, you could choose whether the phone connected to the "Internet", "Work", etc. Basically, you would just change the settings in the "Work" connection to be something that would never connect (a "dummy" network), set the "Work" as the default, and then you were set.
Is this possible with a standard/stock WP7 phone?
No

[Q] Restrict Data Roaming International?

Hey all! I've tried googling/searching XDA, but I must have my terms wrong or no one is talking about it.
Question: Is there a way to restrict which mobile networks my phone will connect to?
Device: Google Nexus 5 32gb, Stock Rom/Kernel with Root access
I'm switching to a T-Mobile Simple Choice plan with free 2g data in 100 countries, and going on a cruise shortly after. A couple of the ports of call are on the list, while others are not on the list. It sure would be nice to just leave my phone on and have it only connect to the free networks. I contracted T-Mobile and was pointed to a document letting me know that I will be notified if charges are incurred, but I'd rather not get charged at all. This I could solve manually by carrying the list of countries with me and only turning off airplane when I am there, but that does seem like a pain to me.
The other problem, cruise ships have cell networks onboard now. These networks are charged as international and not included in the Simple Choice deal. Even if I am in port, I am concerned I may still connect to this netowork. I imagine there is an app I could use to at least see which network I am on (I can't find it indicated in Settings anywhere - probably blind), but I would need to prevent my phone from roaming onto that network when both are in range.
I'd really appreciate any thoughts/suggestions. The only thing I can think of is some kind of custom block that would like me restrict network connections. All way over my head.
Thanks again
Matt
You're going to have to manually select them. I'd turn data roaming off until you get some where you know you can turn it on. Also, most port of calls have Wi-Fi and I'd use that where you can. You can often even get it on the ship at a port, although you might have to find the right location on the ship where you can do that.

Thanks for the tip about Wi-Fi networks. Absolutely. Unfortunately, I'm not even sure how to manually select the network to which my phone connects. Any advice on where/how to select that?

Change Mobile/WiFi failover priority

Hi developers!
I have a question for you:
Recently i acquired some devices for a new project in my job, but due the specific needs we have to connect mainly to mobile network and use WiFi only when the mobile network fails. Android is configured natively to set WiFi as main connection and Mobile as backup (to save battery and money).
I was looking on Google for some app or something to change the priority but i could not find anything so i though that any expert from here could help me to solve this need.
Thank you in advance!
