Aldi prepaid sim Germany

[Confusedone]

Hello everyone. I'm in Germany currently and I'm having a little trouble with the aldi sim I bought.

I registered as a new customer on the median mobile site. I put down my hotel name as the address and put down the sim number and mobile phone number. I was then taken to a page where it told me my customer number and order number. It said something about waiting six hours and it had 2 links. No idea what they meant. My german is really appalling. I'm just wondering if my sim is registered now? I'm sure I've done something wrong I've not had chance to check it yet.

I've had no email and I thought it would ask me what tariff I would like to go on. Has anyone here got any clue about the registration process? I'll try the sim later but I thought I'd ask now. Just found a free wireless access point!

Thanks!
