Hi,
To Import, first move VCF (Virtual Contact File) file from PC to your Android phone, now connect your phone to PC using data cable and then move the VCF File into the storage location of the phone, use the import option in Contacts Section and browse the location of VCF file to add file into your android phone. If the contacts list details stored in XLS from, then you have to convert excel to VCF format first, then follow the above process again.
