The short answer is there is no range!
Because we use GPS(1) and GSM(2) mobile technology, the device talks to satellites and base stations then back to your mobile (not directly from the device to your mobile), so the question is more about coverage than range. GPS coverage is available almost anywhere in the world and GSM is good in most regions, so you can track your animal even if it is in a different state or country! This is unique to Pod, as most other Pet trackers are limited to certain geographic locations or have short-range Bluetooth location abilities only.
GPS signal works best outside in a clear area in good weather. It can be affected by buildings, trees and bad weather. As long as there is cellular reception and GPS signal or Wi-Fi then you will be able to locate the Pod on your lost pet.
