5G data roaming does not work outside the Netherlands?

Hi KPN community,

I have my Unlimited data bundle in Europe from KPN. I am now traveling to Frane and on my way in Belgium, and somehow my data bundle doesn’t work at all

After several times of searching for solutions the problem still remains unsolved..

I really need to use online for paying with Apple Wallet and some other payments as well. It is really frustrating when KPN internet doesn’t work ..
