Hi Margie this is a wireless device and uses a mobile sim card. You connect it wirelessly to the device you want to use, laptop, tablet etc and off you go. It gets the data from the local mobile network and I have found it work really well away from our place.
I am sure that you will need to get a new sim card and top up the amount of data you want to add in bundles 2 4, 10GB or other amounts.
Hope this helps.
