I have just read the terms and conditions of the free sim offer. In this text vodafone refers to the Anynet and Anytime tariffs - not the Simply tariff, which is the PAYG tariff for receiving free incoming european calls this summer. What a pity!
Perhaps it´s worth ordering a free vodafone sim anyway.
Terms and conditions for those interested in the offer:
