So do they sell this in Terminal 3 arrivals area or something? Just to make clear I am not intending to get it delivered into DPRK of course, just want to buy it in Bejing and bring it with me and then use it after crossing the border into China on the train as I do have a device which can act as a modem and share wifi. Infact my computer supports having a SIM card in it so I do not need the device really, but maybe my friend wants some connection.
