WMWifiRouter and the Pro

[Briz600]

Sorry if this has been brought up before. I have done some heavy searching .

I just picked up this netbook and bought a copy of WMWifiRouter. I am on Dream .5 . The question is what settings do I have to look for to assure me that I wont get charged a bunch of money for tethering ?

One set of settings I found while searching was to set
"CheckProfile", "Multi-NAI" and "WModemDUN" all to 0 .
The problem is that "CheckProfile" and "Multi-NAI" dont hold they keep reverting back to 1 when using WMWifiRouter. I dont know if thats normal.
I just had enough problems with sprint and bills I dont want anymore problems

Thanks
