MMS VCF problem in message app in S7

[Ryju Raju]

I am trying to send contacts vcf file as mms from galaxy S7 to another S7, but it appears as text file instead of vcf file in message app even though send as mms option is selected. The message app displayed vcf file in the format below. Due to this, contacts cannot be saved directly.

Begin: Vcard
Version:...
N:...
FN:Tel:0400..
End: Vcard

Has anyone ever see these symptoms before and / or know if there is anything I can do to diagnose / fix the problem.

Thanks in advance.
