Question here today is how can i be sure i am using my acutal wifi connection rather then the telus data internet.

I am using a Wifi SD card, fully connected to my network. Seems like without the WIFI card, it dials a #777 before connecting to internet explorer.. Is there a way to completly remove the connection to telus' internet? or somehow be assured that it will ony connect to my network?

I do not have a data plan, and telus said they cant disable the date goign to my phone, and that i would have to do it manually..

Thanks alot!!
