hi, can you use any "3" PAYG SIM card in one of those mobile internet things that you plug into a Laptop to get mobile broadband? Or do you need to buy a "special" SIM card for that purpose? thanks
no you need a sim specifically for it, they usually come inside a modem dongle which connects to a usb port, however some notebooks do now have a slot to take the sim card without need for a dongle.
