@snidely ... I am watching this "phenomen" since a few weeks. If one of my customers/friends from Germany is calling me from his cellphone they can reach me on the 09 number (+354380...) the system does connect through. As well as the DID number (in my case a London landline). Customers or friends which are trying to reach me from Hungary they just can call my DID without problems, if they try to reach my 09 number they just can call me from the Pannon network, calls from the T-Mobile network will be cannceled by the T-Mobile network system. Same problem in Slovakia, no call are going through the Orange or T-Mobile network. I tried to call my self using my Pannon SIM connected to Orange and T-Mobile as roaming user and all calls to the 09 number has been blocked. This is something that should not happen cause the SIM is useless if I am just by landline calls to my 09 number are reachable.
