Invite Help

I have a iphone 4s .... and in trying to invite a friend of mine to this game and to my server (s93) and its not working ive tryed writing his telephone number his email he has got nothing and ive tried to select from contacs but when i click on this number it just calls him :/.... Can anyone help me???

So far as I know, there's no invite feature in this game.
There is a referral system, but even that is not a guaranteed method of your friend joining your server.

A good way to ensure you both can play on the same server is to rush as fast as you can to lv10 with your current acct and you'll be rewarded with a brand new acct. create this acct on the same day as your friend and it should place you both on the same server.

I'm very curious as to where you input your friends email and phone number.

we've tested and there's no problem with INVITE FUNCTION.
Please confirm your steps:
1. Main Building/General-Kingdom Management
2. Invite Friends to Game
3. select a contact from your contact list or type in the email address of your friend
4. Invite
when you receive the notification of "Invite friend successful", our system has sent the invitation to your friend's email.
Please note that if your friend has set up auto spam filter in a certain mailing system, our system letter might have been put in TRASH.
