Hi, I have a blackberry 8520 and am on Vodafone network. Up until a week ago I was able to access the internet from anywhere with my data package from Vodafone. I still have data left on my vodafone package - but my phone will not connect to the internet unless I am linked to a wireless network. I have checked and my data and roaming are both on. I have also double checked that I have available data on my plan. Can anyone help?
