Subject: Heathrow or Copenhagen Airport Shops

Is there anyone familiar with Heathrow or Copenhagen airports who can tell me if it is possible to purchase pre paid SIM cards at either airport? He only needs it for Denmark, but an EU one from Heathrow would be next best.

My husband is leaving tomorrow for Copenhagen with a 4 hour lay over in London. I had purchased a pre-paid SIM card for his cell phone and it has not yet arrived.....

If it does not come in tomorrow's mail, we need plan 2....any folks in the know?
