Was it your first plan purchase?
If so then the €25.98 will have comprised €12.99 for the one time activation fee plus €12.99 for the plan itself.
This €12.99 Plan is only available to new 48 customers who order their 48 SIM and purchase a €12.99 Plan from the 5th April 2022. A one-time activation fee of €12.99 applies with the first plan purchase.
You should probably qualify for your second month free at the moment so that effectively cancels out the activation charge.
If you need to contact 48 support about this then see the links in my signature below.
