Whatever number can dial the device when SOS number is not set. But after SOS number set, the device can only be dialed by SOS number.

• Activate GPS in a fixed time
• Trigger SOS emergency dial
• Send SMS command “ POSITION# WHERE# URL#”

It varies from different item battery. You can check the specification page of the corresponding item number on our site.

• Stay in the room, under the tree or keep still for a long time may affect GPS signal reception.    
• Whether GPS is shielded or not. (e.g., near military region or community)
• Overhaul needed when device still can’t be positioning even the signal is strength.

• Your SIM card should be valid.
• Please check whether the SIM card is incorrectly inserted.
• Observe indicator light. If network indicator is dark, this problem may be caused by SIM card, you can change another one and have a test. If this still can’t work, please return the device to factory to get an overhaul. 

In order to get text messages sent to your phone when your tracker enters / exits a geofence, you need to add your cell phone number into the tracking app.

You can do this with the mobile app or through the web tracking app.

To get started, first make sure your tracker is completely charged and powered on.

It may take a moment for your tracker to connect to the cell network and get a GPS fix for the first time.  

You will want to download the tracking app for your smartphone (or you can use the web tracking app, tracksolid.com).  For some trackers, there are additional features available only in the mobile app.

You can log in with the e-mail address and password you chose when you purchased or activated your tracker.

Once your tracker is powered on, it should update the map view and display it's current position.  In order to access the Live audio features, you will need to set your cell phone as the authorized number.

There are a few reasons a tracker might not be updating it’s position on the map.  

• The first thing to check is that the tracker is charged and powered on.  
• Next, make sure the tracker is placed somewhere it can get GPS signal.  Trackers get their location from GPS satellites, so they can’t be inside a metal enclosure like a trunk or toolbox.
• Also, they may not be able to get a GPS fix inside a metal building, an underground parking deck, etc.  So if your tracker isn't reporting, there is a possibility that it just doesn't know where it is at the moment.
• Finally, the most common reason a tracker might not be reporting is because of poor cellular service at the tracker's location.   Your tracker sends its location back over the cellular network, so adequate cell service is required.  If your tracker hasn’t updated in a while, there is a good chance it’s in a cellular dead zone and will update as soon as it moves out of that area.

A great way to test your tracker if you just got it is to drive around for a few minutes with the tracker.  This usually solves any connectivity issues that may be the result of poor cellular service in one spot.

First you need to pick the devices that meet your demands, follow the instructions on the user manual to connect the device. You can use the Tracksolid/Car-Matrix Web platform to checkout latest location and status from your cars/assets/people. Apps for Android/iOS phones are also available. Just click Demo on the Login page, then you can have a try.

• If you are using Asset Tracker or Personal Tracker series, there will be power saving mode in which the device will be sleeping during fixed time interval. Please confirm if the device is in those modes.
• Another issue would be the signal strength around the device. If the device is deep down at a parking lot, or surrounded by crowded buildings, tunnels, the signal would be worse than usual, and the odds that device go offline would be higher. You can also cross-check with your cellphone for the signal coverage.
  
• Check the installation. Please do not install the device where it will be surrounded by metal material, because metal cover will significantly affect the network and GPS signal strength.
  
• Check SIM card balance. Recharge the balance to enable Internet access.
• Check the battery life and/or the power supply circuit for the device. Make sure device is power on and stably powered.

If you failed to get the device online after above steps, please contact Jimi for technical support.

• Please make sure you are not testing the device indoor. In some area like inside the buildings, thick forests, in the garage or parking lot, GPS signal will be too weak to fix a location. But there will be LBS or WIFI positioning available, according to different devices.
• When the car is parked or the device is not moving for a while, it will not update location. If you wish the device update locations at all time, please refer to the command lists, or contact Jimi staff.
• Some trackers may have their logics to shutdown GPS module for power saving. Please contact Jimi staff for more detail.
