Very slow mobile internet for the past 3 weeks

Hi ​@Apano, welcome to the community. Do you experience this at a specific location, or is it everywhere? Is it the mobile internet connection (4G or 5G) or Wifi? If it is the mobile connection, have you tried your simcard in a differrent phone to see if it follows the simcard or stays with the phone? Have yopu tried restarting the phone?

We can't see what you see, we only know what you tell us. The more you tell us, the more information we have to try and help. If you prefer explaining it via phone, that is also possible. To do so you can make a callback appointment ('Maak een belafspraak', bottom right on that page).
