If your CSV file looks like:

9998885551,john25,azp25@gmail.com,ricky25,9820420420
9998885552,john26,azp26@gmail.com,ricky26,9820420421
....

Configuration should be the following:

• Filename: full path to your source .csv file
• Variable Names: phone,lastname,email,firstname,mobile
• Delimiter: ,

Populate other values according to your test scenario i.e. whether you want test to stop on .csv file end or re-spin or whatever.

And your HTTP Request should look like:

The main point is that variables defined in the CSV Data Set Config need to match the ones in the HTTP Request.

See Using CSV DATA SET CONFIG guide for detailed instructions.

I would also recommend adding the following entry to your HTTP Header Manager:

• Name: Content-Type
• Value: application/json

elsewise your request will be treated like plain text and may fail.

Also don't forget to disable View Results Tree listener for actual load test run as it consumes a lot of resources and may lead to out-of-memory errors on JMeter side.
