Bicycle GPS/SMS Tracker GPS305 TK305 Quad Band Real-time sim Card Slot Bike GPS

Thanks, the product is excellent..!!!!

The device doesn't seem to connect to GPRS or even simple GSM. I inserted unlocked SIM but it do not register to the GSM network. When using the magnetic switch the LED flashes rapidly for 1-2 sec and then it should be working but it do not connect to GSM even after 24 hours...

the creating is very traditional, when removing the device must pull a cable that connects to the battery, this cable does not have any refuerso, so in a few days this will break.

Bad gps tracker. I dont can work this tracker

The review is for the Coban GPRS/GSM top-tube hidden bicycle tracker (model TK305/GPS305).The tracker uses a simple GPS unit that is able to locate a bike within 100m (using GPS) and within 500m (using LAC/CID).It does not have WiFi tracking nor dead reckoning abilities. GPS cold boot takes approximately 5 minutes.The tracker connects to GSM (2G) networks. For US it means T-Mobile (and resellers like ting.com).Thus the tracker will only be limited to larger cities in US with good T-Mobile coverage.The mobile connection will cost approximately $10/month.The tracker uses the gps103 protocol and can be tested at www.traccar.org servers (demo.traccar.org:5001).There is a Chinese site called [...] that requires 15$/year subscription bought on ebay or aliexpress - never tested.While there is a mobile app, it does require the above mentioned subscription and unfortunately it installs only on selected mobile systems - not tested.The setup is not easy and takes several hours and technical expertise - especially if setting up for GPRS (2G) data connection.The manual is an OK translation from Chinese. It describes what is mostly a terminal like experience using SMS.While setting up I have used about 100 SMS messages.The installation procedure also requires using a hammer quite a few times to make room for the tracker in the head-tube.The tracker has a magnetic "disarm" key that will demagnetize your credit cards if you carry it near your wallet.The disarm procedure is not intuitive, if you miss 2 times you have to disarm the tracker using SMS.Otherwise, the tracker will continue to spam the tracking server every 5 minutes draining the battery within hours.The tracker has several "alarms" - shock, speed, geo-fence, battery, and schedule - which send (location) data to a tracker server (GPRS) or to SMS of an authorized number. GPRS and SMS reporting cannot be activated at the same time. While I was able to trigger the alarms in a test setting with the tracker in the hand, the alarms fail to trigger in a more practical setting with the tracker mounted in the bike. If the alarms fail to trigger, the tracker will be in "deep sleep". I.e. there will be no way to actually reactivate it and get the location and your bike will be lost for ever. The "schedule" function of the tracker does not seem to wake the tracker at the specified interval. If the "deep sleep" function is switched off, the tracker discharges the 700mH battery in less than 8 hours. Charging the tracker includes unscrewing it from the top-tube and plugging in a proprietary 5Vconnector to the side.Practically, this product gives a false sense of security and should be considered harmful.

Does not fit my Rockshox Reba fork. ZERO answers to my e-mails.
