SinoTrack 4G GPS Tracker for Vehicles, ST-901L LTE Mini GPS Tracker Waterproof Locator Real-Time Location Device for Car Motorcycle Truck Taxi with No Monthly Fee Tracking System

I can do my own stereo, speaker and amp installations. I can R and R a transmission but not rebuild a transmission. So I'm plenty qualified to install this even though I'm not an ASE certified tech. Take a picture of the ID on your device! Activate your full size SIM card before inserting in the GPS! Once you get through the install process the unit works well. The description recommended the 'SpeedTalk' SIM card so that's the one I purchased. $5 a month so cheaper than the phone app and you can't turn off this GPS whereas you can turn it off on the phone. The instructions are clear enough. I was confused about the APN. The instructions say "please check with your SIM card provider if you don't know it". That's incorrect. The APN is the example APN that is shown in the instructions in step 6. I sent the short APN message. After that I sent the middle-length APN message in step 7. I did not send the optional APN message with the user ID and password at the end of step 6. Once I did this I logged into their website and nothing (initially)... Shows some location in California which I'm guessing is their HQ. I then looked at the instructions and in the Function section I did #4 to get a google link, no link was sent back. I then did item #1 in function to set control number. Again, the website doesn't work. So I put the app on my iPhone and it works great! Now it's day 3 and I tried the website again and it works fine and it is much easier to view than the app. The app is rated poorly. The app is 4 years old. The app works though. It is clunky and takes a minute to get used to. Don't be put off by the rating. They *should* update the app a little just to get better reviews if nothing else. Severalcomplaints were about 2G service which is no longer around and people were setting it up while 2G was going away. Now this device is 4G and everything I found says 4G will be here for another decade (until 2033) or more. I am using this on a golf cart and I wanted to keep it modular so I could easily move it to another vehicle if need be. To do that I connected the power (red) and accessory (orange) together to 12v positive. I connected the black to negative. I cut the end of the yellow so it couldn't make contact and I did not install the relay. It's another point of failure and so I wanted to avoid that in case I made a bad connection. I zip tied this to the cart frame. The only physical install issue I had was when I pulled the GPS apart to put in the full size SIM the wires unfold that are inside and it takes a little bit to get them all back in. I also dropped one of the screws which took some time to find so don't do this part in the driveway like I did, put the activated SIM in the GPS while at the kitchen table. The replay function defaults to the current day, but you can click on it and pick any begin/end date/time. The speed shown on the reply is accurate enough. My golf cart is limited to about 20.5 mph. On the first trip it showed a top speed of 33kph which is exactly 20.5mph but I know I was doing 20 for longer than the app showed. On the second trip it showed 35kph which is a little faster than I went but still pretty close. Also, I have been unable to figure out how to switch to MPH. If I need to switch this device to another vehicle I just pull off the two spade terminals and mount it in the next vehicle. Because I didn't use the cutoff relay it's as simple as using a zip tie to mount it and connecting the + and -. If you use the relay it will be harder to move. I'm paying $12.99 a month now for an app that tracks stuff, but now I'm going to cancel that and just pay the $5 a month SIM card. I'm very happy with this purchase even though the activation took 30 minutes for the SIM activation and the GPS activation/configuration. Physical install took less than 10 minutes. Absolutely recommended.

Hello, These are very good GPS's with many featutres and best of all the platform is free. You only need a $5/month sim card with 100MB data and SMS. I have installed over 100 of this GPS units for my customers without a problem. Occasionally one is defective but that is uncommon. I alsoi want to let the seller know that A few days ago I placed an order for 12 pcs ST901 GPS. After I received them I had 2 pcs that did not work. My intention was to return 2 pcs for replacement but by mistake I marked all 12 pcs for replacement. So I am returning 12 pcs but only 2 pcs are bad and the other 10pcs are good. I am sorry for the confusion. Please accept my apologies. Thx for your understanding and have a great day.

I bought this to track my old truck with no OBD port. Setup: It was simple enough to wire up to the fuse box. I didn't bother to connect the fuel pump relay. Getting it to register the sim card was the most difficult part. I have another SinoTrack device for my other car, and they both have this issue where you have to insert, remove, and reinsert the sim card over and over again several times until the device connects. The device has a status light for the GPRS (cell tower) connection but it only tells you when it's connected successfully. It doesn't help with debugging at all, because it could be a faulty connection with the sim card, poor antenna signal, unauthorized sim, or a whole bunch of other issues that make setup very frustrating. After setup: I have the tracker set to report to a Traccar server. It works fine for this, and I haven't had reliability issues. I haven't had issues with it killing my battery either, even after leaving it parked for over a week. The GPS position is not precise at all, at least in the city. It is usually around 30-50 feet off from the actual position, so if you need to know exactly where you parked it's not always great like that. The precision is worse than an AirTag, but it updates much more frequently and reliably. If someone were to steal my truck I feel much better having this GPS in there instead of just an airtag.

I think this is a great buy and value for money, the magnetic force it has aswell as the build quality the location accuracy and the signal strength song strong. it works extremely well after installing i dont have any problems at all very easy to use.

They work as a gps but the app will display Ads that you can not skip. Imagine you want to find your vehicle that your wife rides around and you have to look at an alibaba Ad first. Never again.

OK, I had a lot of trouble getting this product to work initially, but I think I've found the root problem. First, this product appears very well constructed and with a lot of thought put into it. The tracking website is free and appears to have many options. The fact you can use this tracker to shut off the fuel remotely is an excellent plus. Now this issue, and I'm still working through it. Although my SIM card has good reception on my phone, the SINOTracker GPS device appears to have significantly sensitivity and will not receive a cell signal unless much closer to source signal, therefore, in my experience, doesn't work well in rural setting unless very strong cell phone signal available. Also, I have been struggling to receive technical support to date, but I will attempt it through the Amazon site. Overall, if I can get this working the way it's supposed to and find a way to improve the signal sensitivity, I would be giving it a 5 out of 5. For vehicles in urban locations, it's a great device.

Funciona muy bien, facil de instalar

Works well, may need some positioning in the car. You can also change the server where it sends data so if you want to keep the tracking private or use some sort of company managed tracking, you can do that, too. Reasonably priced, bring your own sim and thus also no subscription.

Helps tracking your vehicle

Desde el principio ha dado problemas el sensor GPS que fallaba en dar la posicion y la bateria no se cargaba. Despues de un mes dejo por completo de funcionar. Y como la bateria estaba rota me descargo la Bateria del coche. No es recomendable comprarlo.
