Could not establish GPRS connection:

Please make sure your network has granted your GPRS

service

Have you entered all the parameters during the software

installation?

Please check light is lit on your GPRS modem, if not, you

are probably in a RF dead zone or in an area your GPRS

roaming service is not permitted. If light is lit on your

GPRS modem, your SIM card is probably inserted

incorrectly or damaged.

GPRS connection is slow and unstable:

Please disconnect from the network and re-connect, the

network might re-assign you to a better sector in the

network.

If the connection is still slow it indicates the base-stations

near you is having heavy traffic, try to re-connect later or

move to a different location (move to a nearby window

might help).

Could not open the GPRS manager:

Please make sure your GPRS modem is plugged into the USB

port on your computer.
