All about Mobile Data

Who and why might need Mobile Data (APN)?

* Who: anyone with a GSM (not CDMA) phone which does not have a native switch for data connection activation and inactivation. Normally these are phones running a version prior Android 2.2 with no Sense UI (like my old HTC Magic).
* Why: because you don’t want to pay for data traffic all the time and you want to have a possibility to switch data connection off even if there is no such possibility in the phone itself.

When do I not need to use this control?

* If your phone has native data switch available via system properties or as a widget
* If you have a CDMA phone
* If you have problems with this control

How does Mobile Data (APN) work?

* APN is a configuration that describes how your phone connects to the Internet. If this configuration is valid then connection is established.
* When you switch APN configuration off, Quick Settings will go through all APN configurations available in your phone and add a modifier string to the APN and APN-type properties of those configurations. This makes configurations “invalid”, which, in turn, disables data connection.
* Modifier string can be selected in APN control preferences (Menu -> Customize -> APN control wrench button -> select “Disable MMS check box”)

How do I keep MMS enabled?

* MMS has an APN configuration of a special “mms” type. Quick Settings keeps by default APNs of this type unchanged that you can always receive MMS even when data connection is disabled.
* You can configure Quick Settings to disable MMS too by overriding default configuration for APN control (Menu -> Customize -> APN control wrench button -> select “Disable MMS check box”).

Why do I not have a data connection after I enabled APN?

* There is no G/3G/EDE etc. icon in status bar
o Reason: old versions of Android (prior 1.6) didn’t not always reestablish data connection after APN configuration was changed. I had this problem with my HTC Magic when it run Android 1.5
o Solution: You need to force your phone to reconnect. I did it by switching “use only 2G networks” check box in system settings. A shortcut to this check box is available form within Quick Settings (single tap on APN control icon or a text and you are there).
* There is a G/3G/EDE etc. icon in status bar but still no connection
o Reason: I’ve seen this behavior on my Nexus one running Android 2.1 and I tend to refer to Android bug #2207
o Solution: Restart your phone (sorry guys) or use a solution below.

This solution should help in both cases: Switch WiFi on by keeping APN enabled and connect to a WiFi hotspot. Once connected disconnect WiFi again. Now 3G icon should appear and connection should work. At least this worked for my on Nexus One every time.
