Hikaserial Generator plugin for preconfigured serials

-- HikaShop version -- : 4.4
-- HikaSerial version -- : 3.1.2
-- Joomla version -- : 3.9.23
-- PHP version -- : 7.3

I have a set of preconfigured serials such as sim card numbers.
I have difficulty understanding which generator plugin to use for a pack of preconfigured serials in order for the purchased product to select one of these preconfigured serials.
Can someone help explain the workflow to create preconfigured serials, which generator plugin to use for the pack which holds these preconfigured serials so they can be passed on to the purchased product?

Thank you in advance

Hello,

When you import your serials in your database, you do not want to set-up a generator for the pack.
Let the pack generator empty so it will retrieve the serial via the "pack data" (your database).
