There is only one file type that uses the .VNT extension:
Mobile Phone vNote File
Text note format used by various cell phones, such as the S Memo app on Samsung Android devices or the Notes application on Sony Ericsson mobile phones; saved in a text format with a header that starts with "BEGIN:VNOTE" and ends with "END:VNOTE."
The contents of a VNT file can be viewed in a standard text editor. However, the message may be encoded using one of several encoding methods. For example, some VNT files are encoded with quoted-printable, or "QP" encoding. This encodes each character with an equal sign, followed by two hexadecimal digits (for example "=20" represents a space). Therefore, it may be difficult to interpret the text without a QP decoder.
