Referral questions
Where do I find my referral code?
Open the Kudo eSIM app and go to the Referrals section. Your personal code and share link are right there.
When do I get my 3€?
When your friend makes a purchase of 5€ or more with your code, 3€ is added automatically to your balance and 3€ to theirs. Purchases under 5€ do not trigger the reward.
Why didn't we get the reward after my friend's purchase?
The reward only applies when your friend's purchase is 5€ or more. If your friend bought a package under 5€ (for example 1 GB), the referral does not count. This minimum exists to prevent misuse of the program.
How many friends can I refer?
As many as you want. There is no limit, so the more friends you invite, the more you earn.
How do I use my balance?
Apply your credit to any internet package directly in the app, for any country you travel to.
Does my referral balance expire?
Your referral credit stays in your account, ready to use whenever you need data.
