Why does my phone fail to import a big VCF file?

I​‍​‌‍​‍‌​‍​‌‍​‍‌ was confused because my phone kept failing when I tried to import a big VCF file. Eventually, I found out that a lot of devices have limits on the size of files that they can handle. To solve the problem, I cut the large file into smaller pieces. For splitting the VCF file, I got help from GainTools Split vCard Software, and it did exactly what I wanted. The vCard splitter didn’t drop any contact details while splitting the file. I was able to split vCard file content into several small files that I imported one after the other without any problem. This prevented me from losing my major phone numbers. If your device is not accepting contact importing, splitting the VCF file is the safest approach. This application is very helpful and simple to operate, especially for those who are constantly dealing with huge contact ​‍​‌‍​‍‌​‍​‌‍​‍‌lists.
