APN Verbindungsprobleme

[DrBash]

Hallo,
ich hab öfter mal Probleme unterwegs ins Internet zu kommen.
APN schalte ich öfter mal aus um meine Ruhe zu haben, wenn ich es manchmal unterwegs aktivieren möchte dauert es eine Ewigkeit, manchmal mehrere Stunden bis ich wieder eine Verbindung bekomme. Das gleiche Problem hab ich auch manchmal wenn ich ausser Haus von meinem Wlan weg gehen möchte und APN eingeschaltet ist.

Ich hab durch Zufall im Market eine APP gefunden die das behebt sie nennt sich
3G Connection Fix Free


Dazu geht sie automatisch in den Flugmodus und dann wieder zurück auf normal.


Das Problem ist wenn ich APN deaktiviert hab versucht die App es ständig zu machen.
Mir ist Manuell damit geholfen das ich dann einfach mal den Flugmodus per Widget aktivere und wieder deaktiviere.

Mich würde aber gerne mal Interessieren warum es dieses Problem gibt.
Da mein Englisch so schlecht ist kann ich mir da selber nicht so gut helfen.

BeschreibungHelp your phone switch from Wifi to 3G.3G  Connection Fix is a simple tool to automatically work around a known  problem on some phones where automatic switching from Wifi to 3G/packet  data does not always work.
This app contains Ads (top of the  "Preferences" screen). If you would like use a version without Ads (and  support my development of this app) please purchase the "3G Connection  Fix Donate" version (uninstall the "Free" before installing the "Donate"  version).
Important: This app will only be effective if the  manual (Flight mode) workaround described below successfully activates  3G data.
Details:
The simplest (manual) workaround for this  issue is to turn on "Flight mode" and then turn it back off again when  you notice no 3G data connection. This manual workaround is annoying,  and if you forget to do it then you are without a data connection.
3G  Connection Fix will attempt to activate 3G data by automatically  toggling Flight mode on then off when the phone disconnects from Wifi,  if the phone doesn't switch to 3G by itself.
This app has been tested on:
Samsung Galaxy Ace (2.3.4 Gingerbread)
Samsung Galaxy Gio (2.2 Froyo)
Comments and feedback suggest this app may also work on:
Samsung Galaxy Y
Samsung Galaxy S
Samsung Galaxy S2
Samsung Galaxy Mini
Samsung Galaxy Fit
Samsung Replenish
Motorola Droid X
HTC Desire GSM (CyanogenMod 7.1)
If  you try this on a different phone and it doesn't work please email me.  If it works for you please leave a comment (or send me an email) stating  the model of your phone.
Notes:
1. There is a 1 minute delay  between your phone disconnecting from Wifi and this app attempting to  activate 3G data to allow the phone time to try to switch to 3G by  itself.
2. If you are on a phone call this app won't disconnect you but also won't attempt to activate 3G data.
Contact:
If you find any bugs please email me rather than leaving a comment on the Market (as I can't reply).
Privacy  Policy: 3G Connection Fix Free uses advertising services that may be  using cookies, web beacons, and other technologies to collect  information as a result of ad serving. If you do not agree to this, do  not install 3G Connection Fix Free.
A (paid) version of this app  with no ads ("3G Connection Fix Donate") is available to buy (look in  the "More from developer" section). 
This app was written to work around Android Issue #2207.
