Is this a good deal and is Congstar a good provider?

I don't find anything cheaper 25 euro a month is actually good isn't it? But I think the best thing is that the contract only lasts 12 months and not 24.

what do you all mean?

NO PEOPLE KNOW WHAT YOU WANT TO HAVE IN YOUR CONTRACT!

And so nobody can say whether it is expensive or cheap! My God… Always the same.

I do not know if you ever viewed that correctly in the link, this is an installment purchase for the Huwei P30 Pro over 24 months, there's no mobile phone tariff included, in short, you only buy the cell phone via installment payment.
