I have another problem since the update:
My voice call program always tries to connect to AirVantage. Before the update it worked well without it, and now it tries to connect and fails, then the program stops automatically.
Can someone tell me why I can't connect to AirVantage?
In the AT Command Port everything seems fine:

I looked in the forum for help and found some methods that worked for others, but in my case they didn't work.
