Hello,
I'm using Callya USIM. And I used my first 5 giga all, so I bought 25 Euro vodafone voucher and had a top-up on my phone. So, in my USIM, 25 Euro has been top-up. By using this top-up 25 Euro, I'd like to charge my data. However, I couldn't find the way to charge my data. I tried to register 'Meinvodafone' to charge the data, and Meinvodafone required me to write down 'Kunden- oder Tellnehmer-Kennwort'. But I haven't got this kind of password from the beginning of my Callya USIM contract. I tried to find it from the contract, but there wasn't. In this case, what should I do to solve this problem?
