The SIM
A cellular tracker needs data to report. Most vendors rent you that data monthly. Kin prepaid it.
What a tracker actually costs over time
The sticker price is the cheap part. A tracking plan is the bit that keeps billing after you have forgotten you bought it.

What the monthly fee is usually paying for
The app tier
Location history, extra places, or more family members often sit behind the plan. Check what stops working if you cancel.
The first-year-free trick
A year of included service is a subscription having a nap. Run the five-year number, not the first-year number.
Several at once
A kids tracker, a pet collar, and a family app is three meters running. Count them together.
Questions
Why do I have to type the competitor’s monthly fee?
Because we will not publish a plan price we have not verified on the day you read it. Where we have checked a figure it is filled in for you, with the date. Everything else is yours to enter.
What does Kin One cost over five years?
$129.99 per device, once. Cellular data in the US and Canada is included for the life of the unit, so the monthly line stays at $0/month in year one and year five.
Does the calculator send my numbers anywhere?
No. It runs entirely in your browser. Nothing you type is transmitted or stored.
