Your post was blank @ClaireY9830 and the subject line doesn't really explain your issue or question clearly.
If you want assistance from the Community Forum then you need to describe your issue or question clearly.
If you are on the €12.99 plan then you should not be running out of data as it comes with truly unlimited data since August 2024.
If you are on another plan and use up your data allowance then you will need to buy a data add-on in order to continue using mobile data for the remainder of the membership plan month.
If your issue is something else then you'll need to clarify.
