It has to do with whether or not you've currently got a good connection to Google's servers for sync services and the like. From page 27 of their Android 2.3 Users Guide: Network status icons turn green if you have a Google Account added to your phone and the phone is connected to Google services, for syncing your Gmail, Calendar events, contacts, ...

The project mentioned by BobFlemming is the Serval project, and they are also on twitter. The android application will be available soon apparently. Thought I'd mention because not entirely straightforward to find it through the youtube link and that the twitter account isn't advertised on the site. Also I cannot +1 or comment yet so adding it as a reply.

It could be done technically. AFAIK all communication between MMS enabled components is done via standard TCP/IP. But in a regular provider setup the MMS store and forward server(s) (MMSC) are only reachable via the providers network. That's why you can not send and receive MMS via WiFi. It's also the reason why you can not make a call and send/receive an ...

YES. You will use it as a regular phone, but will be disconnected from the networks (Facebook, Twitter, IMs, Sync, etc) YES. You can access your calendar offline. And yes, you can sync when Wi-Fi is available. Yes, you just disable data traffic.

Its been tested by a group here: http://arstechnica.com/gadgets/news/2011/01/researchers-enable-mesh-wifi-networking-for-android-smartphones.ars So it is possible.

You are (not) in trouble. Or at least you cannot tell anymore by simply taking a look at the notification bar. With Android 4.4 (KitKat) came a few design changes; one of them was to turn those notification icons permanently gray, officially to be "less distracting". So how can you tell if there are issues with your connection to the Google servers? ...

Just kill the APN Connection settings. Somewhere under settings. And there is actually a switch for mobile internet. Disable that as well. Worked like a charm for me. If you can't find it, add the Power Savings widget to your home screen, it has that option

As you are rooted, you can use DroidWall to control network access on a per app basis. From the Market page: Front-end application for the iptables Linux firewall. Allows you to restrict which apps can access the network. This is the perfect solution if you don't have an unlimited data plan, or just wants to see your battery lasting longer.

I think I already posted this in another answer -- but I don't remember where. As I think it where different details that time (more a general "what consumes most"), here some details from a reference Motorola Droid. Data taken from a German article named Energiesparplan (Heise is a very famous technology publisher in Germany; Google Translate Version here): ...

Of course not. Your WiFi will go through your WiFi chip to AP and to some other ISP. There is no connection with 3G just like you can use WiFi even without SIM. But your carrier can(though highly unlikely) use some tracking program to track you and find what you are doing. Even if they do, the WiFi usage won't be counted as 3G. One advice I'd like to give ...

Here is what I use that do not need an internet connection: https://play.google.com/store/apps/details?id=com.androidintercom https://play.google.com/store/apps/details?id=com.remaller.android.wifitalkie_lite

Not quite answering your question, but switching off Background Data usage should stop chatty apps from doing anything in the background, and restrict it to just apps you launch and use, rather than apps that are syncing and checking for status updates all the time. If you add the Power Control Bar (built into Android since 1.6) to your home screen it's ...

You can pretty easily disable cellular data on an android device without root. On Android 2.2 and above, you can go to home --> menu --> Settings --> Wireless & networks --> Mobile networks --> and then uncheck Data enabled (on phones with Motoblur, the Data enabled setting might be in home --> menu --> Settings --> Data manager --> Data Delivery ...

I dont think it's possible, since the data is sent through the cell network and not through a traditional Wi-Fi style Internet connection.

Short answer: yes. It depends on the currently enabled Wi-Fi sleep mode. By default, Android disables Wi-Fi when your device goes into a sleep. In this case, 3G is the remaining mode of network communication, and it gets used by Gmail/Gtalk push notifications, etc. Obviously, this network communication takes its toll on your battery time. If you disable 3G ...

You can give a try to an app developed by a XDA Developers Forum user gyagapen that essentialy the app intelligently manages switching between both your WiFi and 3G data connections as you move about: CleverConnectivity CleverConnectivity is an application that helps you to manage your data and wifi connection in order to save battery. How does ...

No. You don't need a data connection plan to use OnePlus One or any android phone for that matter. Calling and texting will work irrespective of internet connection. However, having a data connection will be useful if you want to use some apps on the go.

Depends entirely on how many contacts you have, how often they change, how often you set it to sync, etc. Paying for data as you go is generally a bad idea with an Android phone, they use a lot. You should be able to shut off 3G though (probably dependent on the phone) and just use WiFi. Although, it might be more difficult to prevent it from using 2G ...

A little bit yes. (See comments below) The app will make this seamless but should still use a bit of data. Edit: After checking Google Help I found this: By calling your own Google number When you call your own Google number and sign into the Google voicemail system, you’ll have the option to place a call. Just press 2 and enter the number. ...

Not sure if this question is on-topic on Android Enthusiasts. But I work with XMPP and Android, so here is my answer: As Lie Ryan already stated, a handover from one mobile cell to another is almost always transparent to the TCP stack on Android devices. But there are situations where the IP of your Android device will change. This are typically GSM/UMTS ...

You probably need to use some sort of 3rd party program like Tasker, Locale or AutomateIt. These programs allow you to set triggers such as: starting an app screen on/off connected to Wi-fi location etc... and perform actions based on that, such as: toggle data toggle GPS run an app etc...

You could just check the logo on the top bar? On the right you have time, battery, signal and either g/3g/h or the wifi logo. this image (random googled) shows the tab with the wifi logo while this rather bad (also random google) image shows it with 3g

On my Galaxy S, you can hold the power button for a second and a menu will come up. Just hit "Data network mode" to deactivate it. You can reactivate it the same way. If you don't have that, you should be able to go to Settings -> Wireless and network -> Mobile networks and uncheck Data enabled or Use packet data or similar.

The previously mentioned serval project now has an android app available - https://play.google.com/store/apps/details?id=org.servalproject

If you have Android ICS, you can set the "Restrict background data" setting for each app. Go to Settings > Data usage, select the Mobile tab, then scroll down and select the app that you want to restrict. You can set the option at the bottom of the page that appears. If an app is built properly, setting this option will disallow the widgets and ...

Most HSDPA / EDGE CDMA networks don't support data and voice at the same time. CDMA Modern GSM networks (including 3G and HSDPA, but not EDGE) do, and LTE will, so I'm not sure why you're having this problem. It's possible that Dual-Transfer Mode may not be enabled on your phone. Alternatively, your network might not support it. (Info on DTM.)

You can always perform a speed test and check for packet loss( Speedtest.net, pingtest) Alternatively, you can try calling the skype Voice Testing Service which should be in your contacts from before, and if it isnt there the username is echo123 i belive.

Go to SETTINGS > WIRELESS & NETWORKS > Wi-Fi SETTINGS Press MENU and choose ADVANCED. Click Wi-Fi SLEEP POLICY and make sure NEVER is selected. This might help your WiFi connection remain connected. These are available on my Samsung Spica running v2.1 (Eclair).

I use APNDroid (Also available in the marketplace for free). You can easily turn data on or off with the press of a button. Add the APNDroid widget to your home screen to easily turn data on or off.

You could try using Quick Settings to toggle the 3G connection. It has seperate toggle switches for 3G and Wifi but when wifi is on it automatically turns off 3G. When I click the toggle to turn on 3G it automatically disables the wifi.
