[Q] HTC 7 Pro with Swisscom

Hey,
Ich have to post it in this General Forum, because i am a new noob here
I bought a HTC 7 Pro second Hand. Here some Details without an SIM-Card inside:
Software: Windows Phone 7.5
OS-Number: 7.10.8783.12
Operator: Swisscom
Bootloader: 5.11.2250.0
I come from Germany and this Phone comes from Switzerland. Not sure, but Swisscom is only in Switzerland available isnt it?
When i start the Phone with or without SIM Card, i got an Massage, that there is no SIM Card or invalid SIM Card inside.
So have the Phone a SIM Lock? or something else? Hardware defect? How can i check this?
Is there a way, that i can use the Phone in Germany with any SIM Card?
I hope u can help me
