The reasons for not connecting to the Internet are as follows:
You are in an area where there is no 3G coverage. At the top left hand side of the screen it shows the coverage available at any given moment. With 1 bar of coverage the connection would be very difficult or non existent. If the message NO SERVICE appears, this means there is no coverage in that area.
OUR ADVISED: Move or change the position of the device to a place where there is 3G coverage
You are not properly connected to the device unit. It is normal that mobile phones and laptops connect to already known networks that are saved in their memories.
OUR ADVISED: Check that you are connected to the device.
The unit sometimes gets very hot depending on the environmental conditions and the hours of usage. When this happens, almost always the message HIGH TEMPERATURE appears on the screen, which could complicate the internet connection
OUR ADVISED: Turn off the device for a few minutes until it cools down and then turn it on again.
If there is a large concentration of people where you are (for example, in stadiums, concerts or festivals) the 3G antennas become saturated. This will complicate the internet connection. This can also happen in touristic places where there is only one 3G antenna for the whole area.
OUR ADVISED: Move to a different area or position so that the device connects to a less saturated 3G antenna or wait until the concentration of people lowers.
