*2025* TKSTAR 4G Mini Waterproof GPS Tracking Device with Powerful Magnet Long Standby Tracker Locator for Kids Seniors Pets Cars Vans Motorbikes Fleet Taxi Spy

Set mine up with a 99p O2 PAYG sim from a corner shop. The device takes 'normal' size sim cards, however it comes with adapters from nano -> normal and mini -> normal. It also comes with a sim extraction tool - this is for your phone presumably, as the device uses a push to remove the card, having some tweezers to get it out help since it doesn't quite come out far enough unless you have nails. Once it's actually in it's very unlikely you'll be taking it back out anywayFor O2..Whilst charging the device via USB. Purchase and top-up an O2 sim card (£10 etc), the O2 website didn't work for me when paying by CC ( it kept saying an error occurred but not why ), however a top-up card from a shop ( my local petrol station in this case ) did just fine. Insert the sim card and just follow the step by step instructions in the surprisingly not-too-bad manual, response times between each setup text is roughly 4 - 5 seconds.For APN settings use APN : payandgo.o2.co.uk, User : payandgo and Password : password.For security I set the speed alert to be 20km/h since this is for a second car and used infrequently, if it's moving at that speed then, well, someones nicked it or I've left it rolling down a hill. I just have to remember to set the alert to some ridiculous speed that I can't attain before I set off.Shock alert supposedly lets you know when the vehicle starts moving, however this triggered for me once when the car started, and yet another time didn't trigger at all. So for me Speed alert is the safer option. There's no configuration options for shock sensitivity.By default the time of the alerts were an hour out due to Daylight Savings, however this is configurable. This works fine and takes just one text message to the tracker to re-configure.The app if you decide to use it is really quite usable, no frills - does the job, is free, hasn't crashed, realtime tracking works fine and uses google maps (on android at least). Accuracy is supposedly 5 meters. That's a touch off for me, car is at the rear of the house, tracker says its at the front and I don't live in a shoe box, but I can live with that.All in all, this is much better than I expected, easy to setup, solid as a brick - in fact very weighty, could happily knock someone out with it, the magnets are also VERY strong.Assuming it lasts would happily buy another. Any questions just shoutUPDATE ( after one month ) :The shock alert actually fires mostly okay, it's not what anyone would call consistent but whilst the truck was in for servicing I could tell when they were working on (or moving) it. It occasionally fires when I get in the truck and start/move it, sometimes not. It's very much dependent on where the tracker is located and perhaps the vehicle. I'm still not going to rely on it.The disparity I've mentioned between the tracker's location and where the truck actually is ( in my case was a healthy dose of meters ) was down to the location of the tracker in the vehicle. The truck has aluminium panels so I'd positioned the tracker down low, this was entirely my mistake as I'd wanted to use the magnets to ensure the tracker didn't move, moving the tracker up higher and the tracker is detected much much closer to where the truck is. The manual suggests 5 meters, it's actually now down to less than that thanks to just positioning it a touch higher.I've only had one oddity, the tracker sent me a text to inform me the truck was at 0km/h (my speed alert was set to 20km/h), and it wasn't a shock alert, I'm not even sure what it was, perhaps a heartbeat, albeit after three weeks, however the manual that I have doesn't mention such a thing exists. Checking the vehicle showed it was fine. Out of the multitude of alerts I've put it through this was the only one that stood out as odd. It's only happened once.I should also mention that the app helpfully shows the current battery life, after four weeks mines at 40%, which so far, within reason, tallies with the manufacturer's expectancy considering I've mucked around with it within that time. They say 90 days, I reckon an easy 60 days no problem and 90days may be possible if I stop abusing it, plus charging it is fast, like, sit down have a meal and watch a movie fast.My Mum now wants one, not sure why, if anyone nicks her car then they're probably not going to get very far, but still, for the price if it gives her peace of mind then so far I'm happy to recommend it to her and anyone else.

This is the second TK-905 GPRS Tracker I have bought and we use these in our cars.They are very simple to set up, use, maintain and are much more effective in terms of cost than any contract trackers.Depending on the settings you use, the batteries can last for well over 4-6 weeks if not more and are about as accurate as you get which I would estimate to be in the region of a matter of a few metres (signal coverages depending).A cautionary word about SIM cards though … these do not work on anything other than a 2G network, so SIM cards from 3 (as good as they are) are not an option.These SIMS use data and SMS so there’s no real need for anything else as a SIM package and some of the cheapest packages start at £10 per month/£120 per year, which seems rather steep for the amount of data we use with these devices.I recently went with 1pMobile who provide a SIM that works on all networks and the SIM clips out from a standard size (too big for these) right down to a nano SIM (which fits these devices).I chose the £30 for a year package which means I don’t have to touch this SIM for the next 12 months unless I go over £30 worth of data - which is highly unlikely!After that it’s a top up every 3 months of at least £10 which more than suits me considering I started out using these with the GiffGaff SIM at £10 per month so the cost consideration kind of speak for themselves.NB1: I am not affiliated with any SIM providers and I pass this on purely because I wish I had known this in the beginning!The set up instructions are not great but you can kind of work it out anyway and the setup to installation/use can take a matter of minutes.NB2: Make a note of the SMS instructions that some with these things, they are very helpful, especially if you lose a GPS connection because you can reconnect with a simple text to your device.You can tweak some settings in the devices’ web portal (details in the set up guide) but customer support is minimal, which is not so much an issue when you consider that these are about as ‘Janet & John’ (other fictional characters are available) as you can get.The app that accompanies these things is brilliant if all you want to do is track where your car is/where you left it or where it has been when (for example) you’ve been on away on holiday and it shouldn’t have been moved or driven anywhere.There are low battery and shock/tremble alarms but in my experience they are more trouble than they are worth (who wants your car telling you the tracker battery is low at 2am in the morning or when your away on holiday and the shock/tremble alarm is way too sensitive and sends repeated false reports)That said, if you want to know if whatever you’re tracking is picked up or brushed passed by someone/something or when the battery gets to 20%, then these functions might work for you.All in all these devices really are more my cup of tea for the cars, simple to set up, simple to use, no binding contracts, control over the running costs, no constant recharging of the batteries and they fit into the car (or whatever you want to track) really easily.NB3: Don't forget to change the default password and also to write it down somewhere - you know you'll forget it!

Essentially there are two ways of operating this; calling it and sending it SMS messages in order to retrieve its location and configure it - or - get a SIM card with a small data plan, activate mobile internet (GPRS / 2G in this case) and use the basic smartphone app. I've done the latter and I've got to say that for the amount I paid for it, it works really well. Refresh rate on the 'real time' tracking is 15 seconds and it uses a tiny amount of data, I've been using it for two days and it's only used 250 KB. Accuracy is reasonable and wholly dependent on where it's placed in the vehicle (if you use this as a car tracker), placed low and under the car the accuracy will get you to the right street - unobstructed i.e. on the rear parcel shelf, it's down to a few meters.The instructions are translated (possibly from Chinese) but straight forward enough. Once you have the app on your smartphone, you won't need the instruction sheet as you can send commands to the device from there.
