Any unlocked GSM cell phone, Freedompop for the SIM and service since I am an avid CNET Cheapskate follower. The amount of data is below the free level so that works for me.
100 megabytes is more than ample for each month and for the tracking service I use https://play.google.com/store/apps/details?id=com.greenalp.RealtimeTracker&hl=en
Start at long updates like hourly then move down as you figure out your data use.
Remember I wanted to do this for cheap.
Hi. I was wondering if any of you could suggest what GPS tracker or service to use. I am thinking of getting one for my son's car. Yes i could easily use iCloud to track him but that depends if he has mobile data enabled, etc. I want something that i'll be sure of being powered on and tracked anytime.
