but i think its very good , it shows your location at google map , i give my GT-Sim to my family , and the last day in there travel , i used this service and see them in the border without calling them is costs 0.09 euro , and i hope to make it much lower , and about if you don't wont to track you , like your wife

, don't give her you user name and password for the GT_Sim account .
