Stopping the Adult Block being Lifted

Hi,
My son who is 17 has just got a Lebara SIM as have I. He can unblock the adult content filter as Yoti detects him as 18.
Is there anyway to stop this? His SIM is not part of my plan as he pays for it himself. I was hoping there would be content controls on your app but it seems not. Is there anything you can suggest please? I cannot stop him accessing the Yoti page, entering his number, being taken to the Yoti page, photo taken and block lifted.
Thanks

yougothis I'm sorry to hear about your situation. Do you know which method is been used with the Yoti filer, for example is it a photo upload or something different?

Hi Martin,
I believe it is a photo on Yoti that thinks he is older than he is.
Thanks

OK thanks yougothis, I'll need to check if Lebara or Yoti are the best place to get assistance with this. I'll drop you an @ mention once I have an update for you.

yougothis I've received an update on this and the team has advised you contact customer support who can help you sort out the content block.
