Problem switching from WLAN to mobile connection (and back)

[karlhelxp]

Hi,

if i get out of my home and lose my WLAN-Connection, mostly the phone doen't switching automatically to the mobile connection (i'll get only an EDGE connection with my provider at my hometown).

The signal-strength is high (4 bars) and i can do telephone calls as well as sms. But i don't get an internet connection (E in top of the signal-indicator).

After disable and enable the sim-card, i'll get the internet connection.

Sometimes the other way doesn't work too. After opening the configuration menu, at the latest after opening wlan-configuration, the phone will connect to my wlan.

This behaviour is very annoying and reduces the fun with my E dual enormous

Any other with the same problem?

thank you for reading,

KH

Check if the same problem remains if you try using another SIM card or reinstall the phone software using SUS.
