I see it .
The 'Unlimited' data service need a preproetary stack software on the supported OS, Windows and Mac.
My patch support a lower layer, recognize as normal modem, but do not provide such a stack.
If you want to use 'unlimited data service', you are forced to use another OS rather than Debian Linux :-(
You may want to use Debian GNU/Linux with it, you may be charged 'EXPRESS PACKET PLAN' rate.
