you can get a data gsm hookup from T Mobile for $20 a month . The lowest sim chipped phone plane is $30 a month. Its worth it for the money IMHO.
you can get prepaid gsm phones from T Mobile as well though you would have to be carefull not to let the minutes run out or your shit would get whacked.
The other question is will the GSM carrier allow trianglelation of the GSM signal.

I'm not sure that it actually does that, I believe it has a GPS device embedded within the hardware. It just uses the SIM card to relay the GPS data retrieved from the GPS over the internet to your monitoring device.

I have tried to design an application that triangulates the cell phone signal with cell towers but the problem is that there's no set database or API out there that contains all cell phone "tower id's" and their respective lat/lon. It's almost impossible unless you actually work for the carrier and have some serious leverage over their technology.

Not to mention that all cell phones are different, most don't have an easy way(or no way at all) to retrieve data on which towers the phone is currently using.

Hate to bring this thread back from the dead (especially since I was the last poster) but I found something on another forum that speaks directly to this.

Since the tracking device requires a SIM card, I found out that Boost Mobile offers pay-as-you-go service and uses SIM cards. With that in mind it should be possible to charge up the phone for a month of data use ($0.35 a day for unlimited data - $10.85 a month total) and have it use that SIM card. Then each month or two add more money to it and you're golden.

I might do this now that I think of it. Security for my car is definately worth more than $10.85 a month.

I tryed the prepaid Boost Mobile phone sim card deal.

Basically Boost didn't work on this unit. When using certain sim cards from companies, you'll have to know the APN(access point name) for that company. In order for the gps unit+ sim card to work, one has to send an SMS message to it in order for the unit to relay messages back. This message includes password, APN, and an IP address. When I called Boost to get there APN, they said didn't have one, or they wouldn't give it to me. I'm pretty much on strike 2 on my frustrated list. So after reading the owner's manual carefully, these 3 companies are supported by the unit: T-Mobile, Cingular, and AT&T for the US. There are more supported companies on the APN list in the manual.

So I'm double checking what I need to do with the manufacturer and I'm going down to T-Mobile and getting a GPS enabled sim card added to my Family plan. If this doesn't work, I'll be stuck with a 2 year plan, I'll retract all my claims of what this thing can do, and go looking for another tracking system.

I guess T-mobile has a pay-as-you-go plan as stated by Driftfreaq.

This particular unit claims to be a "breakthrough for 2007" on gps tracking and personal security. I'd really like to see it work.

* No Props to Boost Mobile until they start having techninal info when needed. They could also use a better techical support line. * Or if someone can get an APN from them, I'll retract that statement.
More updates soon!

well, keep us posted.....

its been a good read

Tenchuu · 02-04-2007, 10:36 AM

If you have cigular, I know a buddy that got a second phone added to his current plan for $10/month. and get a free/cheap pphone, steal it's SIM card and you are good. for an extra $10 a month and as long as youput texting on your plan that device would be useing off your minets.

also if this sues cell phone towers to triangulate, and was not a true GPS beacon, then it is about worthless to me since i can loose cell phone reception in about 30min from anywhere in my state.

It doesn't triangulate off of the cell tower signals, it has it's own GPS device built in so that won't be a problem. It will be worthless to get the data to you though if you're losing signal a lot.

^^^Right, the sirfstar chip uses 3 satellites orbitting earth to trilaterate position.

***S14DB*** · 02-04-2007, 05:11 PM

Boost Mobile uses the Nextel network which is not GSM.

Yes, Once The unit looses cell signal it can not relay the information it receives from the satellite. But, it's much cheaper than a Iridium based solution.

extra-made garage · 02-06-2007, 04:37 PM

Success!! I go to T-Mobile and pick up there lowest cost pre-paid phone deal(>30.00). Go Home and install the sim card. I text the unit with coordinate codes, about 14 times, to receive the gps unit's location. After gaining back the results, I input coordinates into Google Earth's search bar. Basic results, were pin point accuracy with the unit charging to the laptop or car,

unit w/usb wire attached and not charging= within couple feet accuracy
unit without usb wire attached and not charging= within a block radius accuracy

I'm troubleshooting on how to get the coordinates back to my laptop on the gps tracking software. It has something to do with my comports or something

Justing waiting on word from the manufacturer. Either way, I'm happy with it so far that it gives me general coordinates.

*MELLO*SOS* · 02-06-2007, 04:59 PM

Why do you send the GPS unit coordinate codes 14 times?

This sounds very interesting, idk how I missed this thread. Does the device have an external antenna for the cell or gps signal? Can you program it so it sends you coordinates if it moves during a time period? For example can you tell the device, "look this is the car's home GPS coordinates... And the car should be here sleeping between 11pm and 8am, if it moves more than 6 feet then send me a msg"...

14 times to check for information feedback and accuracy. The unit worked better when it was charging attached to the laptop. I guess this amplified it's signal. I presume the usb wire connected to unit would pretty much act as an external antenna, because it would wend coordinates back within a couple feet. For the time period question, not sure, but it does have what they call a Geo-fence feature. Where if it is moved outside certain coordinates, it will alert and send info. I haven't tryed this yet.

*MELLO*SOS* · 02-06-2007, 06:30 PM

The USB wire isn't good at all for GPS reception or as a cell antenna. I think you're seeing better transmission when it's on the USB because it's drawing power through the USB line instead of it's internal battery. Same should be true when wired to the car's electrical system?

Are you texting a request for the device's GPS coordinates -- or are you actually sending GPS coordinates to the device?

Yeah the Geo-fence sounds like what I am thinking of, cool!

Sounds really interesting please update the thread with more info as you learn more

jrmiller84 · 02-07-2007, 04:36 PM

If and when I get to the point of needing one of these, I'll probably break out a multimeter and a soldering iron and use one of these to keep the battery charged when the car is off.

http://www.hobbyengineering.com/H1660.html

Throw it on the shelf behind the back seat. Only problem would be how much tint is going to affect the power output. This one has (I believe, not sure about the amperage though) the same specs as USB output and is only 1.5 in. x 1.3 in., you may be able to mold it into your dash or somewhere else crafy. Just a thought.

Thieves beware!

DRIFTING_SIL_EIGHTY · 02-07-2007, 07:10 PM

heres one that my friends coworker has. havent really read through it all but it seems promising and they state "NO RECURRING/MONTHLY FEE'S". if your in socal, dont call foothill nissan in La Crescenta because they dont do it. though they are listed as a dealer.

Tenchuu · 02-07-2007, 07:21 PM

I talked to cingular today, i can add a line to my cell phone, any planthey said, for $10 a month and that comes with a free sim car.

might want to ask your provider about "adding a line" with a sim card to an existing account. told the guy about what it was going to be used for and he was veary helpful.

any yes, hard wireing is the only way to use a GPS, more power = a better stronger signal.

No Montly fees, but you have to pay for locates? And most likley you need a sim card and plan?

Yeah, I got the same reaction from my T-mobile guy. He thought it was the best thing since sliced bread. But back to the unit, as long as the unit is fully charged, it will send accurate coordinates.

Texting a request for the unit's coordinates. The unit will then reply back automatically with it's information. Geo- fence is
