One question im registried at paypal but when i log in it wants my credit card number why?

Because different countries have different Paypal rules, most countries require you to provide a credit/debit card number.

Make sure you are visiting www.PayPal.com and not some other site trying to steal your info. If you are then they are probably wanting to make sure you are indeed the rightful owner of the account.

Now i have an another question:

Because the creditcard isnt an really good way (for me) ,
I prefer Mobile boosting but now I have the question works mobile boosting with the german mobilephone card Aldi talk?(Its supported by Emobile)

AFAIK every sim card type and every gsm service can access onebip.

If you have doubts, try to register at www.onebip.com

And I have to give nothing more than my password phone number name e-mail adress and where I live?

Also after that i can get my boosters?

If you register, you'll be able to purchase mobile boosters, of course.

Now i registried i bought an 50 booster and have another question^^:

Do I get some extra items for the booster because my friend got some items like sets^^

Since promos were disabled, you don't get those anymore.

You used to get sets and items, but that doesnt happen anymore.

omg what a bullshit
