Top up Netzclub prepaid SIM without bank account
 

I got a netzclub SIM with 100MB data free and worked well. I used up the 100MB in one day and now need to get the 500MB data bundle for 6.95 Euro. Now is there a way to top-up netzclub prepaid SIM without a bank account?

you can use o2 loop reload vouchers that can be purchased nearly in any store.
Please note that if you book the 500 MB package the 100 MB free package is automatically cancelled and will not come back on this SIM even if you cancel the 500 MB package later on.

Thanks. I will get a Lidl SIM for data then as they are also on o2 network which allows Skype calls.
