How can I surf the 5G network with my laptop?

Does the laptop itself have to be '' 5G-capable '' or is it enough if I get a 5G surf stick and plug the stick with the SIM card into the laptop?

A 5G stick is enough.

In itself, a USB surf stick is the same as a built-in antenna. Therefore it does not matter whether via USB or built-in. Your tariff and the mobile network must be able to hold 5g.

Thank you.

If your stick and your SIM card (tariff) allow 5 G access, you could surf with the new SStem. However, currently only 0.001% of the German area is covered.
