In other words no service. Dead.
So what to do when you have an urgent need such as communication with the doctor.
You reach for your cell phone of course.
So how do you get cell phone data cheaply?
I have been using Tello. Not only do they offer plans and less than $10 a month, but for $25 you can get eight gigabytes a month.
That might be enough to handle all of your internet without any other service.
Even better you can modify your usage at any time.
