Hola. I think your Vodafone SIM is fully prepaid (= prepago). So they don't have your credit card data to charge it. It'S not a contract. It will only renew automatically when you have enough credit loaded on your SIM account. In this case it's min. €15.

They have a double data promotion running which gives you 3GB instead of 1.5GB. If you need more data, you can only renew the whole package ahead of time or you will pay excess fees. How this can be done is described in the FAQ on the linked website. But you have to top-up (recarga) €15 first.
