Nearly all of them don't allow topping up over the phone. By which payment system do you want to top up? We only list international accessible payment systems here. You can link it to a German bank account and have other more convenient ways, but this is not open for international visitors.

All providers don't accept credit or debit cards to top up online on their website. Only exception I know of is Lebara. But you can use third-party top-up agencies like www.prelado.de  They do it without surcharge on Visa, Mastercard or PayPal for most German SIM cards. There is an app of prelado too, but I don't know if it is distributed through non-German Play Store/iStore as well.

I consider adding prelado.de as an internationally accessible third-party website to top up German SIM cards, if anybody can tell me, if one can find the app abroad too (in non-German stores).
