Hey guys. Travelsimshop.com and travelsim.com are slightly different. Travelsimshop.com is run by an Austrian company, Onzoone, which is just one of the Travelsim distributors. Travelsim.com is by CSC Telecom, which is the company that actual provides the service. So, it's the same card but different companies directly selling it.
