It is unlikely you can directly convert .vcf files (vCard contacts) to Samsung Kies SMS backups (.sme), i.e perform direct vcf to sme conversion.
You could possibly import contacts to a phone backup, but converting them to a SMS message backup does not make much sense. If you are looking for something specific, please write it in the discussion below.
This conversion entry was verified by us and conversion was flagged as wrong or not possible.
Usually this happens when the conversion would try to convert different types of data between each other, such as audio to image, or it is not possible because incompatibility between programs, caused by closed file formats, very limited support etc.
If you find entry that you feel is flagged as bad wrongly, please tell us in the discussion below with as much as information as possible so we can fix it.
