Cancelling China SIM card from abroad

I went to a China Unicom shop and bought a SIM card, but the lady told me I should come into the store with my passport to cancel it before I leave China. Is this accurate? I was kind of hoping to just forget it about and let it cancel herself as I don't want to go through the extra admin. Does anyone know if anything bad will happen if I just throw the SIM card in the trash?
