Paying for a sim since December doesn't automatically mean that you will then pass a credit check.
You might want to look into this yourself by signing up to a site that allows you to view your records, one credit checking site Sky uses is Experian so you could sign up to a free trial with them, just remember to cancel.
If this is the case then any upfront charges that you have paid should be refunded within about 14 days.
