Hi @Ellarinjo The whatsapp outage should now be resolved https://www.theverge.com/2022/10/25/23422343/whatsapp-down-outage
If still an issue with Messaging are you using standard Texts/chat and are you receiving error Messages. is the issue on Data or Wifi? In any case idea try a soft Reset, Hold the Power and Volume Down Button until the screen turns off, the Device will automatically Reboot. However may need to reset connections, General Management-Reset-Reset Network Settings.
If issues persist try reinserting Sim card, otherwise may need to connect your Network though.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
