Where is the option to send a friend a referral link? (not a group plan)

I am sure I have sent them in the past, but cannot see the option on the mobile site. 

[MSF]

If you are on the app, open up and then click on the bottom left hand "you" icon.

"Refer a friend" is then the fifth option down and gives you the chance to send the referral link for a £10 gift card.

If you go to the conventional website and log in, it is the first option at the top.

Hope this works for you.
