DITO WoWfi 799 unli 5g

Hello.Ask ko lang,kasi nag avail ako mg DITO WowFi 799 5g unli + 50gb 4g,so my concern is,every time na maconsume ko na yung 50gb 4g,hindi na ako maka signed in sa wifi..nag aappear is "Please sign in to your wifi account....." then ayaw naman maka sign in..always ganun..false advertisement lang ba ang unli data? Thank you
