Hello @Katarzyna Zabron
Welcome to the customers help customers Community of Vodafone.
At the moment it is only possible to take out a subscription with a Dutch ID (BSN). It is therefore not possible to request a subscription for your Polish ID. Did you provide a Dutch ID? Because you should have seen this in advance when ordering.
How you can arrange this, no idea. You need a Dutch ID when applying, otherwise it is simply not possible. You can buy a prepaid card, it doesn't matter which ID you have.
