I have a verizon bb torch 9850. In my office at work, I don't have very good signal but we do have wifi. So, facebook is slow if it's accessible at all and my battery drains quickly. I was told by one customer service rep to turn on my wifi connection so that it will run off that and not my mobile network. Another customer service rep told me this would drain my battery more quickly because the two connections are working against each other. Does any combination of coneections affect sms or mms ??? Just wondering if anyone has any input on the subject ??? thanks for your help !!!!
