Bought my phone 3 weeks ago and have the required $15/mo data plan. (Rep says a 'Family Data" plan is coming but that's for another post.) My problem is I don't want to exceed my data plan limits and I use data access on my phone almost exclusively with WI-Fi - ummm, except for those times I'm in physical range of wifi but the connection fails. All that for this question. Is there a way to disable access to ATT data use but still allow wifi access?
