I am having trouble getting the data connection to work on my 1520 and in need of any help. Thank you in advance for any tips. I have a line on my At&t account that has the unlimited data plan for the ipad and in which the sim uses the "broadband" apn, it works flawlessly in the other two devices I have that I could put the sim in. I have put it in my PS Vita and in my beloved HD2 running on Android and both didn't need any setup at all. I have also tried putting it in my Lumia 920 but no go either. I have searched for different APN settings to use but to no avail .. still no luck .. Has anyone else gotten it to work?
