چطور مخاطبان حذف‌شده را بازیابی کنم؟

Imo usually does not provide a feature to recover deleted contact information. Once you delete an imo contact, it is usually not possible to restore it. It is recommended to confirm whether you really need to delete the contact before doing so, to avoid unnecessary trouble. If you need to contact them again, you can manually add them as a contact.
