When you select a package for a free test (how many days is the test for)?
A free test is valid till 11:59 PM at night, activation is immediate.
Will the free test last for 24 hours? or just a couple of hours?
When you take a free test via the billing, you will see a message where it is written - when it will be finished. The earlier you take a test, more time will be left for the test (valid till 23:59).
