What is the best VCF version for old phones using Excel contacts?

[Ciyoyis2420]

I need to export my contacts to a VCF (vCard) file so I can import them into some older mobile phones (basic phones and early Android models). I have noticed that there are different vCard versions available, like vCard 2.1, 3.0, and 4.0, and I am not sure which one works best for legacy devices. My main concern is maximum compatibility rather than advanced features. I do not want contacts to get skipped, show incorrect fields, or fail to import altogether. Which VCF/vCard version is considered optimal for older mobile phone compatibility, and why?

The best VCF version for old phones using Excel contacts is VCF 2.1. Older mobile phones and basic devices support simple contact formats. VCF 2.1 includes basic information such as name, phone number, and email, which makes it easy for old phones to read and import contacts without errors. For an older phone, you can choose the VCF 2.1 version.
VCF 3.0 is mostly used on modern smartphones and email applications. It supports more contact details and better formatting, but some older phones can not fully support this version.
VCF 4.0 is the newest format and is mainly used by advanced smartphones and cloud services. Most old phones cannot read VCF 4.0 files.
Using SoftakenSoftware Excel to VCF Converter, users can convert Excel contacts and choose VCF 2.1, 3.0, or 4.0 based on their mobile compatibility needs. VCF 2.1 can be opened on any Windows version and gives you 100% accurate results.
