Is this the type of SIM you're referring to? http://www.ebay.com/itm/Germany-BLAU...item43c9abaf05

Will there be any problems using a SIM that someone else registered? I know that Germany requires an ID and/or German address when purchasing SIMs and obviously this SIM wouldn't be registered to me.
