It is because the position data of your device still can not be sent back to GooTrac server by
GPRS. There must be some problem with the SIM card, or the GPRS APN settings, or some
other telecom problem.
Following are some of the possible factors which may cause the data can not be sent back to
GooTrac server by GPRS.
1. The APN setting is not correct
Please check with your mobile operator for the latest & exact GPRS APN settings; if
Username & APN_Password required for the APN settings. Please note that the data
provided by us were what found in the internet, which maybe out of date. You must check
with your local telecom company for the correct APN data.
2. The SIM card does not support GPRS communication
Please check with the telecom company if the GPRS function of the SIM card has been
activated. Maybe the SIM card does support GPRS; but not yet been activated. You must
call & ask the telecom company to have the GPRS function opened.
(Please note that one can link to internet by WAP, or MMS, or GPRS; but only GPRS is good for real-time
tracking; WAP & MMS are not workable - i.e. it is not for sure that the SIM Card does work on GPRS,
even though you can link to internet with the SIM card.)
3. The GPRS communication is simplex, not duplex
Please check with your telecom company if the GPRS communication is duplex not simplex
- i.e. the device can both receive & send out GPRS data.
4. The 3 SMS commands to set up the GPS tracker were not sent correctly
Please double check the 3 SMS commands sent to the device, and make sure the
commands were sent correctly.
5. Firewall or Anti-virus Software
The operation of GooTrac is blocked by firewall or anti-virus software. We suggest you to
disable all the firewall/protection for the PC used for testing; and have this PC linked to
internet directly, not thru router/intranet... After the communication problem solved, then you
add on the required protection one by one, so that you can find out where the problem
resulted from.
Why I can’t find the IMEI# of my device in GooTrac main screen?
