I have a Isurf 3G 7.2 mbps Isurf data card. I am unable to surf 3G with this card. What is the problem? In my opinion the latest firmware will resolve the issue. If so, then please provide the firmware.
Connection Speed 3G is reached when you are in an area with maximum signal. This means that the device is capable of 3G speeds but it will never maintain a constant connect with 3G because different interference. You don't need a firmware update at this time.
