So I have had a nexus 4 on att for a good few months now and i recently changed to a mobile share plan with the other members on the account and now actually have more data per month than before. I am not getting the proper hspa+ speeds that I should be getting. I have tried chatting with customer support but i feel like i am hitting a brick wall. any suggestions on how to get that? I have read its a combonation of apn settings and getting the plan provisioned for 4g data but these reps refuse to accept that as an option at all! any suggestions would be greatly appreciated!
