import record limit

import record limit

I'm trying to import records to a new application. I receive the following message 'Record limit reached. Kindly upgrade to a suitable plan to import more records.'

This is a free account. I am importing 43 records. Each record has 1 field. There are 435 records in another table with an additional 14 in another table.

Why am I hitting a limit?
