Bought a Call ya sim from the supermarket. Tried to register according the instructions, unable to get through password registration. Then i find out from forums that this is a recurrent problem with their website. Cost of getting it registered in a shop was 40 euros. Tried contacting their customer service - all chatbots in german and asked to call them instead (if i had a number i would not have bought the sim in the first place)Went to a physical store at Schillergalerie Dresden, salesperson took one look at me with my prepaid card in hand and said that I brought it onto myself for buying the card from the supermarket so I will have to sort it myself (this was ad verbatim) I had not even had a chance to ask my question, perhaps not worthy of his time to serve customers who were there for a contract.wow vodafone, customer service at its best.Anyway. its a scam - pay 40 euros and get it registered, or try doing it yourself but the website has a glitch so you cant anyway.not one friendly for non german speaking or visitors.
