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 123456F, 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.
Step 1: Set up your Webpage for GPRS Tracking
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.
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.
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.
Enter the details of your tracker:
Name – whatever you want your tracker to be called e.g. “Tracker” or the person’s name
Device type select PT-20
Unique ID is the 15 digit IMEI number found at the end of the location texts (which you get by texting 123456F to the tracker)
Phone number for the SIM within the tracker in the international format. NOT your own phone number!
Device access password is 123456. NOT your account password!
Then click “OK” at the bottom right.
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 the mobile SIM provider for the SIM inside of the tracker.
This sets up the correct APN (access point name), IP and Port to allow your Tracker SIM to connect to the internet. Please text exactly what is shown, including the capital C and the comma! You should get “Set APN and IP okay!” back from the Tracker. If you get “ERROR!” then you have texted it incorrectly. The text message you send will depend on the SIM network – we have provided the most common ones (for the UK) below. If your network is not listed, search for its APN on google, and add the APN after 123456C in one of the examples below, in substitute of the existing APN.
Step 3: Enable Your GPS Tracker for GPRS
Finally, you need to activate the GPRS tracking whenever you need it:
Enable GPRS uploads on the GPS Tracker
This command now tells the GPS Tracker to start uploading the packets of information to the server. If you refresh your map page on the tracking website, you should see its location.
To switch off GPRS:
The Tracker will automatically upload its location every few minutes or so. If its not moving for a while, then the GPRS will go into standby until the Tracker moves again.
A little forewarning…
When 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 123456F command – you will still get a text alert sent to your phone even if live tracking is enabled.[toggle title=”If you got stuck…”]
If you follow the guide correctly, it will work – look closely to see what you might be doing wrong. Here are some common mistakes:
- You haven’t enabled online tracking by sending 123456D 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 PT-20.
- You didn’t put 123456 as the device password.
- You made a mistake in the APN text message.
- 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.
We wrote this neat little guide to get your online tracking working better on a Smart Phone (Android, Blackberry, iPhone etc). Although, you can always just text the device too for a location.[/toggle]
