Question about Digitec iot Data Flat

The whole thing looks good at first glance. However, depending on the application, it may have a decisive disadvantage. The provider Digital Republic does not assign public IP addresses. This means that the card can only be used for remote maintenance with great difficulty. Dynamic DNS does not work. Remotaccess is not possible. If you only want to surf, you are well served with this. Have any of you already tried remote access with this card?
