I think the current tariff is ranging from 3 to 8 GBP per MB while using aboard. I have got the card without an antenna, but the reception been on and off even at the airport. Remember to ask for the adult content enable, otherwise you won't be able to use MSN messenger or access similar site. The card is only good if you got reception for 3G other than that the GPRS is too slow. But well it does the job when you are on the move.
