Great product overall. The only problem I had was my Login ID (sticker on the unit) wasn't activated, so it just kept saying user name or password wrong. I emailed sinotracker my User ID and they activated it. So far this gps unit is spot on accurate �.I also used speedtalk for the sim. Which is working flawlessly.F. Y. I. Speedtalks APN Is: wholesale (lower case, no user name or password for U. S. ) you'll need it for the setup. �Check your ID immediately upon receiving this item by downloading the sinotracker pro app to see if it's activated. If not email them quickly. It takes a day or two for them to get back to you and activate it.
