A 4G tracker with a SIM inside and a plan after 3 months
The PAJ PET Finder 4G is a small collar tracker with a built-in SIM that reports over 4G LTE. The listing says it arrives with the SIM pre-installed and three months of PAJ's Premium plan included, and that a subscription is required after that; PAJ's page also says 3 months of Premium included and lists Lite, Basic and Premium tiers in its FAQ.
PAJ's manual page says the built-in SIM is activated by choosing a subscription duration and paying, and its quick-start outline covers charging and a first outdoor calibration; follow that page for the steps. Tracking is viewed in PAJ's FINDER Portal app or in a desktop browser.
The listing's box row names two rubber covers, three coloured LED caps, three Velcro fasteners and a charging cable with the tracker. PAJ's page describes a Velcro strap for attachment and says the tracker is designed for pets over 4 kilograms.
Battery life: three different descriptions
PAJ's product page and the listing say the battery lasts up to 10 days in power-saving mode, and the product page adds 1 to 3 days with daily tracking active. PAJ's page also describes a Wi-Fi Home feature for extra battery savings.
PAJ's technical data sheet, whose file is dated April 2024 and labelled for the Black version, gives different figures: a battery duration of approximately 5 days on standby and approximately 9 hours in operation, from a 3.85 V, 500 mAh lithium-polymer battery. The listing's table gives a 700 mAh battery, and this listing is the Blue version.
PAJ's documents do not explain the difference between these battery and runtime figures. Ask PAJ which battery capacity and runtime apply to the PET Finder 4G you are buying before relying on either.
Updates, history and coverage
The data sheet says live mode updates the location every 60 seconds, and that route information for the last 365 days is available. PAJ's product page likewise says the tracker records location history for an entire year.
PAJ says the tracker works in over 100 countries, and the data sheet says the current position can be viewed on the map at any time through the FINDER Portal, with alarm notifications by app and email.
The data sheet lists alarm functions for geofence, speed and battery. PAJ's page adds live tracking, a low battery alert, a speed alert, activity monitoring and shared location access for family members.
Weight, water rating and operating range
Weight also differs. The data sheet says 32 grams, while PAJ's product page says the tracker weighs only 48 grams and the listing gives 1.69 ounces, which is about 48 grams. The listing's dimensions are 3.11 by 1.26 by 0.75 inches.
The data sheet rates the tracker waterproof to IP67, and the listing's features row says IP67 with a water resistance depth of 1 metre. PAJ's product page describes it as 100 percent waterproof without an IP code.
The data sheet gives an operating range of minus 20 to 70 degrees Celsius and 5 to 95 percent humidity, and a GPS accuracy of up to 5 metres.
Light, sound and finding the dog
PAJ's page lists an LED light and a call-training feature that plays a unique sound through the app. The data sheet lists sound and light functions.
PAJ's manual page lists FAQ topics on powering the device on and off, LED meanings, route recording, portal connection, alarms and charging; we did not open those answers and do not summarise them here.
The listing says the tracker can be followed in the PAJ FINDER app or web portal, and that it sends virtual fence alerts. PAJ's page also lists geofence alerts.
Warranty and support
The listing's warranty field says 2 Year Manufacturer. We did not read PAJ's warranty terms, so we cannot add conditions to that line.
PAJ's page advertises free shipping and 30-day returns on its own store, and its manual page lists support by WhatsApp, email and phone.
Because the battery, capacity and weight figures differ between PAJ's own documents and the listing, keep the order record and confirm the specification with PAJ support before relying on any single figure.
