Thanks horndoctor, yes I tried this...When I manually try to activate the data connection (when the G sign is "greyed" like in picture 2), data connection is not possible, it just says "Connection failed for unknown reason".

Neither manually nor automatically does data connection work.

I can only get a data connection when randomly (or via forced reboot), the band symbol becomes like picture 1 again...

It might be the ROM as you say, I will see if I can reflash it with something else like newest Eneergyrom...But nay idea what the greyed symbol on picture2 actually means?

if it is not the ROM could it be anything else possibly?

I am sure its not Vodafone since the same SIM in my old tytn II has no issues.
