Is there a limit on how many times I can share my referral link?

Of course not. There's no limit on how many times you can share your referral link, or how many times it can be used. Give 10% and get 1GB valid for life* (Lifetime Prepaid Plan) or 5GB/10 days (GoFi Prepaid Plan), always. It's a win-win.

*if refilled once per year
