More information
The default PIN is 1234 and the SIM is automatically activated when placed in your phone. You can sign up for a data option when you buy the SIM but be sure not to use data until you get a confirmation SMS. The SMS will begin with "Dobry den, prave jste zahajili vyuzivani sluzby Internet v mobilu na den." Once a data plan is activated it remains in effect for one calendar month and is renewed automatically until you cancel it yourself. If you do not have enough credit at the time of renewal, your rate will automatically change to the basic Vodafone mobile Internet on that day. The daily rate renews automatically every day on the same principal.
