Hi, friends and some tell me that I have ipad only with wifi and if I want to call thro F.time or message did I require emails or person use iPhone shall it's possible I use his #.
I'm not quite sure what you're asking but hopefully this will help:
You can use Facetime on a WiFi only iPad. To call someone using Facetime, the person you're calling needs to give you the email address and/or phone number associated with their Facetime.
That would be "number". FaceTime and iMessage can both be initiated by using phone numbers, if the person on the other end has an iPhone. FT calls will be received on the iPad using a registered phone number, even though it does not have a phone number of its own. The number associated with the AppleID will route calls to the iPad.
If there is no iPhone, it's back to email addresses.
First # means number. It's mean that number option is available for calling if the number is associated with Apple ID if I understand is correct then tks to everyone.
