how can i recall all my contact numbers

Hi gai177,

Welcome to the Apple Community,

where some of us do our best to help each other troubleshoot.

Wondering:

• which Operating system is installed on your iPhone
• what happened to the missing / lost (calls ? emails ?) contacts
• from where (iCloud ?) (Email accounts?) you are thinking of, for retrieving your contacts.
• whether you have an iPhone back-up, (iCloud? Computer ?) and where you might be able to access contacts.

If possible, and you want to try retrieving your contacts from iCloud:

try this discussion thread for how to do that"

or

Apple have an article online that may help:

Restore contacts, calendars, bookmarks and more using iCloud.com:

OR if you do not use / want to use / iCloud

Contact numbers in "Contacts" app, are generally compiled from your email accounts.

(When you link an email account to the Mail app, you have the option to add those contacts.)

you may want to try the article:

Set up mail, contacts, and calendar accounts on iPhone

Eg: Says:

Set up a contacts account

1. Go to Settings  > Contacts > Accounts > Add Account > Other.
2. Tap Add LDAP Account or Add CardDAV Account (if your organization supports it), then enter your server and account information. See Use other contact accounts on iPhone.
