Why is my cell phone contract always declined?

My requests for mobile phone contracts with the Huawei P30 Pro are rejected in principle. I have no negative Schufa entries or open accounts with anyone and am able to pay the contract as I have a regular monthly income. Why is my mobile phone contract always rejected? I have every vendor by tasting from cheap to more expensive but a contract with cell phone I just do not seem to get.

That's not because of Schufa.

Have an extremely bad Schufa and about 1 month ago, the Samsung Galaxy s10 on DeinHandy ordered. (Provider o2)

would have accepted and I had to make a down payment of 5 euro.

How old are you?

18

Then it may be your age. The providers could be afraid that their money could not get. Even if you earn enough monthly… The providers do not see that.

Where did you always try to order? Directly with the offerers or also with third-party suppliers?

Mostly third party since the contracts are directly overpriced at the providers last I tried it at MediaMarkt.

Try it over your mobile phone. Best telecom or O2 take.

Can you try it over winSIM?
