Credit on your Vodafone Card is active always for a period of 10 months after last charging or after buying, if you haven´t charged. After your credit expires, you still have a three-month period to renew your Vodafone Card. During this period it is necessary to recharge the credit on your Vodafone Card, otherwise it will be cancelled altogether. After extending the expiration period of your credit you should recharge a minimum of CZK 200. In this way you ensure the extension not only of your credit, but also your Vodafone Card. If you don?t recharge your credit during this period, your phone number will be automatically cancelled. You can always check the expiration period of credit on your Vodafone Card in Self Care.
