Evo Wingle Showing red Signals (Stable)

Hi all,

I have Evo Wingle (usb) and from some hours ago there is no INTERNET. When i checked the device it is showing 4 signals bar RED and stable without flashing. What does this means? Is the package over and do i have to recharge or the connection is there but very slow or no speed at all?

Secondly, please let me know if there is any other way to check the remaining data for Evo wingle instead of using its software as I am out of country and i cannot find any link to check on-line.

Best Regards
