Setting up GPRS for Online GPS Tracking

Setting up GPRS for Online GPS Tracking

WARNING: Please read this page carefully!

If you follow these instructions step by step, then you should have no problem. If you “skim read” or miss bits out, then you will get stuck! We often hear “I’ve followed the online guide and it just won’t work”, when whole steps have actually been overlooked.

Its not as complicated as it looks. You also do not need to use GPRS unless you want to – you can continue to locate your tracker via the simple text functions. However, the live online tracking of GPRS is very useful for those who want it. Locations are uploaded from your GPS Tracker to the internet – this then allows you to see, in real time, the location of the Tracker on a website.

You can still get location texts via 6660000 and 9880000 if live tracking is enabled.

To enable live online GPRS tracking, the SIM card in the GPS Tracker must have a “data plan” – which then allows connection to the internet. Data plans can vary greatly in cost. GiffGaff supply an adequate data plan, with 300 texts and 60 minute call allowance for just £5 per month without contract (amazing value), or just 20p per day of use (you can switch the function on and off with text commands). If you’re in the UK and don’t already have a GiffGaff SIM but want one, you can order one here where you’ll also get an extra £5 via our partnership link.


Shortcuts:
Step 1: Set up your Webpage for GPRS Tracking (GPSTrace website)
Step 2: Set up your SIM for GPS Tracking (APN)
Step 3: Set up Your GPS Tracker for GPS Tracking

Step 1: Set up your Webpage for GPRS Tracking

gps-trackers-gprs-1
Visit GPS Trace (clicking opens in a new tab, so you can refer to this screen as well).

Fill in your details to register for free. Don’t worry – it’s safe! Please write your username/password down somewhere so you don’t forget them.



gps-login
Once registered, go to orange.gps-trace.com to log in with your chosen username and password. If you visit the main homepage instead (which might be in Russian), you can click on the symbol in the top right to be taken to the login screen.


gps-trackers-gprs-1
On your page, click on the big “activate” button.

An information window will pop up. Untick the box in the lower left corner (to stop it popping up again), then click the “X” in the top right to get rid of it.


gprs-watch
Enter the details of your tracker:

Name – something to let you identify the tracker

Device type – select “Easyroad Technology GT98” from the dropdown menu

Unique ID – this is the 15 digit IMEI number found in the texts you receive from your tracker, and also on the box

Phone Number – of the SIM card inside the tracker, in international format (+44). NOT your own phone number!

Device Access Password – 0000. NOT the password you chose for your account!

Then click OK.

You will now see a foreign map – this is because we need to set the Tracker Watch to be able to upload its data to the right server. Once you have set up the tracker for GPRS in Steps 2 and 3 below, you will see your tracker appear on the map, and can track it in real time. The important thing for now is that we have set up the account to receive the data – we now just need to get the data sent.

Step 2: Set up your SIM for GPS Tracking

You need to text the following to your gps tracker, depending on your mobile SIM provider. This sets up the correct APN (access point name) to allow your SIM to connect to the internet:

GiffGaff #802#giffgaff.com#giffgaff#password#0000##
Vodafone Contract #802#internet#web#web#0000##
Vodafone PAYG #802#pp.vodafone.co.uk#web#web#0000##
Orange #802#orangeinternet###0000##
O2 Contract #802#mobile.o2.co.uk#web#web#0000##
O2 PAYG #802#mobile.o2.co.uk#web#web#0000##
T-Mobile #802#general.t-mobile.uk###0000##
Three #802#3internet###0000##
Tesco Mobile #802#prepay.tesco-mobile.com#tescowap#password#0000##
Virgin Mobile #802#goto.virginmobile.uk#user##0000##
BT Mobile #802#btmobile2.bt.com#bt#bt#0000##
ASDA Mobile #802#asdamobiles.co.uk#web#web#0000##

You will receive a “&802&CONFIG OK&&” text to say it was successful.

Step 3: Set up Your GPS Tracker for GPS Tracking

Having set up the APN correctly, this last section now allows you to program your GPS tracker to send the location information to your GPSTrace webpage. When the site receives your data, it will automatically match it to your webpage because of the IMEI and SIM number information you entered when activating your unit in step 1.

    #803#193.193.165.166#20372#0000##

You will receive a “&803&CONFIG OK&&” text to say it was successful.



Finally, you need to activate the GPRS tracking whenever you need it:

Enable GPRS uploads on the GPS Tracker

This function now tells the GPS Watch to start uploading the packets of information to the server, via the information that we have just set.

    #730#180#1#0000##

In this example, 180 means that it will take a data point every 180 seconds. The number 1 means it will upload the packet with every data point (so it will upload every three minutes). If you text #730#500#4#0000##, then it will take a data point every five minutes, and upload them all every twenty minutes (so you will get four data points updated on the map at once). These numbers are variable.

You will receive a “&730&CONFIG OK&&” text to say it was successful.

By this point, if you return to your online tracking page on the internet, and hit refresh, you should see the location. If not, text #904## (see below) and then refresh again in a few moments.


GPRS Text Messages

Text these to the SIM card in the GPS Watch.

    #901## Retrieve the tracker parameters
    #902## Check the GPRS information you’ve entered
    #904## GPRS connection command (start the online tracking)
    #905## GPRS disconnection command (stop the online tracking)

A little forewarning…

geoWhen looking at the tracking history over the course of a day, you might be confused when you see something like shown in the image – especially if you know that the person hasn’t left their house.

This can happen over night, and is called “drifting”. It happens because the accuracy can stray as satellites go in and out of view, the Tracker is likely to be indoors for a while (where GPS coverage isn’t always available), there may be electrical interference (e.g. particularly if the tracker is in an apartment block).

Because the location is being uploaded every minute or so, there is more chance of these inaccurate “blips” being picked up.

When the person wanders, the path should be a lot more accurate. In this scenario though, remember its the dots that are the location reports – the straight lines connecting them are just to give an idea of a route.

If ever you aren’t sure, just send a 9880000 command – you will still get a text alert sent to your phone even if live tracking is enabled.

It’s likely that you missed something, or made a mistake with a text. Please do check through again to see what you might have missed. Here are some common mistakes to check:

  • You haven’t enabled online tracking by sending #904## to your Tracker’s SIM.
  • Your SIM card doesn’t allow data (if you used a GiffGaff SIM then this isn’t going to be a problem).
  • You selected a device type other than “Easyroad Technology GT98”.
  • You didn’t put 0000 as the device password, you put some other password.
  • You made a mistake in the APN text message (Step 2).
  • You made a mistake in the Server IP text message (Step 3).
  • You haven’t put in the correct IMEI number – check your location texts (the IMEI is at the end of a location text) and double check you entered it correctly.
  • You forgot to put “+44” before your phone number in the settings.
