5)Does this Global GPS Tracker have an onboard speaker and MIC©
Yes, the Global GPS Tracker (Quadband + Two Way Calling) comes with a built-in speaker and MIC for
you to hold to your ear and use like a cell phone. The sound quality is excellent.

Two way calling, does that mean I can use this GPS tracker as a cell phone©
Kind of. You will be able to receive calls from anyone that dials the phone number associated with the
SIM card in the tracker. You can only dial out to the 3 numbers preprogrammed by you in the GPS tracker.

Any tips for me before I use this GPS tracker©
Yes, just a few things to keep in mind: 
1) Make sure the SIM card is compatible (only 2G, 2.5G, 2.75G SIM cards work) 
2) Make sure there is money left on the SIM card and that it has not expired 
3) Make sure there is no PIN code associated with the SIM card 
4) Make sure roaming is enabled on your SIM account if you are in a different country

How do I make sense of the longitude and latitude data this unit provides©
Both Google Maps and Google Earth can easily translate the data into usable visual information. You can
also use the included trial software.

How does a GPS tracker actually function©
There's a sophisticated GPS microchip embedded into the heart of this tracker which continually reads its own location from low orbiting global satellites and then utilizes the GSM infrastructure operated by major cellular network providers via the SIM card to transmit its current location to you.

I'm a mom and I'm trying to figure out how I can put this product to use.
OK, picture this. You drop off your teenage kids at the library, but you can't be sure whether their there studying after you dropped them off, or off to a friends house for some tomfoolery. Just hide this in their knapsack and send a text message to the SIM card within the GPS tracker & the location in precise latitude & latitude will be sent to you automatically from the GPS tracker. Then you can then check their location using Google maps and see if your kids are really at the library or...at. The. Mall.

How do I reset everything to the default settings©
Send this password from a cellphone to the SIM number of the GPS unit via SMS text message: 

#999#0000## 
If you have changed the default password of the GPS unit then you need to substitute the 0000 from above with the correct password.
