How to invite friends with the help of invite-code
To invite friends you need to tap on in Nim Account section or find the corresponding field in the Settings field. Copy your invite-code by tapping on it and give it to someone you know, or share it as a link by tapping on "SHARE PROMO CODE". For each user registered through your invitation you get 2880 nims, and the user you invited gets 1440 nims.
Make sure that VPN is turned off on your device, otherwise the invite-code may appear incorrectly or not appear at all.
