Hotspot/wifi/internet help?

Long story short, we are moving. We are going to be living with my mother for a bit until we can find another place to live. However, she doesn t have internet. We re not sure how long we will be there, so we don t want to get locked into a contract that forces us to keep it there for a certain period of time. (say a year). Me and my boyfriend have xboxes, phones, and laptops that we would be connecting to said internet.

We tried doing some research, but are totally lost. Is there some hotspot/wifi thing that we can get that will be able to do what we need?
