This box converts cellular to wifi. If you have good cellular but no internet this works well. You will need a new sim card and an account with Telus. You can also travel with this around the Telus network area. Take it camping if there is cellular, you can have wifi! The battery is not included, but it is not needed for operation. I had this for 3 years, it works well but now I have home service. More info on the service and plans here: https://www.telus.com/en/bc/business/small/internet/smart-hub?topic=internet&INTCMP=sbs_internet_link_explore-smart-hub
