beyond frustrated.......the unit I ordered was from amazon prime for 29.99. It came with a European power charger with no adapter......so I asked amazon to ship me a different one with the standard power plug pictured. While waiting I tried to make the first unit work....I tried ATT go SIM, I tried Tmobile, Trac, H20 with no luck of getting the unit to respond to my text. I now have like 4 prepaid phone accounts that I'm going to have to cancel and clean up. The second unit amazon sent me was the exact same unit with the same results. I tried to call ATT and have them add the IMEI numbers to SIM. That didnt help...still no response. I really cant afford to give up on this. I really don't feel safe flying anything other than overhead stuff without a GPS tracker. I have heard that there is clone knockoff versions of the TK102 and I am beginning to believe that is what I received. Others on the net are reporting success with a device that LOOKs like mine but is probably the real thing. Can anybody shed light on whether these units work, where to get the right version, and is it worth my time. I wished there was a legitimate US manufacturer of a tiny GPS unit. I would gladly spend the extra money to avoid dealing with these Chinese made headaches. Any input is appreciated.
