Since I should not use my swiss cell phone-number in the US (quite expensive roaming) I decided to get an AT&T Sim-Card called ‘GoPhone®‘ for my iPhone 4. As soon as I started using the number I received a call that was not intended for me. A little bit later I received following text message – without hesitation I replied correspondently:

Message of an unknown person

Unfortunately AT&T could not forward the message to ‘Unbekannt’ (= Unknown)
