Review on GSM SIM Card for GPS Trackers - Pet Kid Senior Vehicle Tracking Devices - 30 Day Service with Roaming in US, Canada & Mexico by Wayde Lash

Works like a charm. Best way to track for $5 and easiest way to see it. I have it on iPhones. You insert a SIM card after creating a Speedtalk account and paying for the service I received to test for $5 then I send a message with my account phone with the LOCATION. Infinitely I take it on my regular phone then I removed the sim card put it in my gps tracker and it worked great now tucked the device in the car another option now to use in an old phone and the SIM card to keep in If you park your car in a bad or shady area where there is a high rate of theft and tracking with your iphone or android you will find an easy way with my phone not for the real time gps pay tracking service. Pay only $5 per month. I'm sure every car or kid costs $5 a month. Speed Talk uses the T-Mobile network, so it works with any unlocked phone, or any Metro, Sprint, or T-Mobile phone. version or at&t if your phone is not activated for all networks
