Yes, many GPS dog trackers can work without cell service by utilizing other communication methods, such as satellite networks. However, the ability to track in real-time may be limited in areas with poor satellite reception. Cellular IoT is more than valuable when a device cannot establish a connection with satellites, perhaps due to poor reception or obstruction. It can switch to cellular networks to transmit location data. This ensures that pet parents can still track their pets even in areas with limited satellite coverage, such as urban canyons or dense forests
