My question is: Why?
I have N70. If it is in 3G mode and I am calling to any 2G or 3G recipient or receiving a call, having my phone in 3G, a data connection is initiated when a voice call starts. The data connection ends when the voice call is terminated. I see two calls (voice and data to internet configuration) in the log then. Voice call is incoming or outgoing, but the data call is always outgoing.
Is this normal functionality over 3G?
What is a purpose of the data connection during voice call even if I am calling to a device without any data capabilities?
Or is this one of installed apps spying on me? Is this possible to know, which application initiates the data call?
