The sim should activate more or less straight away but sometimes for unknown reasons it doesn't appear to sim using another phone I would give Sky a call as they might want to send you another sim to try.
150 is the free number to use from a Sky Mobile or Sky Talk phone otherwise under "Need more help ?" link at the bottom of the page on this link is the number to call Sky on:

When you do call say nothing when the bot speaks to you about what your call is about as it should then route you to somebody.
