I recently bought one of these from eBay:
This one to be precise! - http://www.ebay.co.uk/itm/360543779238
I have a secret location for it although it's not finalised - for testing I had it hooked up to spare car battery in my VW camper. Hopefully my location (on an XT660Z Tenere) will be suitably covert, dry and vibration free.
It's a Chinese clone of a GT02 - describes itself as an "Accurate H02". After much poking about on the internet and trial and error I now have it working as I want.
I used a PAYG SIM from GiffGaff:
https://www.giffgaff.com/ - �5 per month gives 300 texts and 20MB data a day, with reasonable EU roaming (rubbish elsewhere).
To actually set it up took a bit of effort but here are my successful steps:
*ZC#000000#07123456789#07987654321#
To bind a mobile handset to unit:
*ZC#unitpassword#mobilehandsetnumber#unitmobilenum ber#
*APN#000000#giffgaff.com#####
Set up data connection on unit
*APM#unitpassword#APNname#user#pwd#
the user and pwd can be left blank as I did
*IP#000000#193.193.165.166#20490##
Set up IP address to send data to (Orange Trace GPS)
*IP#unitpassword#IPadr#portnumber##
The default unit password is 000000 - NOTE: some commands are preceeded by an asterix *
It responds to commands by text and replies correctly - these are the commands I've used:
GOOGLE
Sends text with a Google map reference
VER
Sends text showing unit firmware version
CX
Sends text showing unit settings
XTxx
Sets update interval in seconds when moving
NXTxx
Sets update interval in seconds when stationary
*MVALMON#password#
Turn on movement alarm
*MVALMOFF#password#
Turn off movement alarm
To have web based tracking and other useful things - like "Geofence" warnings when it moves out of a specified zone, like your garage! I used Orange Trace GPS - which can be found at both these addresses - I used the svcs address to set up the account (you need to switch language to English, unless you speak Russian of course!).

You need to enter the units mobile number, its full IMEI and I used the following IP address in the unit: 193.193.165.166 and Port: 20490
I told the website to think the unit was a
GoSafe 911
The web side of things was fairly straightforward once I got the APN details into the unit so the data connection worked.
The other consideration is data usage. I have it set to report its location evry 15 seconds whilst moving and 80 seconds stationary. I think each report is 300 bytes. So based on 10 hours moving and 14 hours stationary (very generous on movement) works out at less than 1MB per day.
Battery drain is another consideration - it claims 0.2mA on standby and consumption of 0.3w/h. That doesn't seem much but like most things I guess it adds up over time if the bike isn't used (I tend to hook up an Optimate from time to time).
Either way it works and for �17 was bloody cheap and a monthly cost of �5 to �6 is worth it for the fun tracking!
Peace of mind is pretty good too.
