Been using a galaxy note 1 717. changed apn as first post using tfdata as sk337sk337 suggested. NO data at all. called ST and told them to I needed my internet provisioned for LTE. Support told me it was done. Again no DATA.
The ninth and tenth digits of an at&t compatible sim was 26. Should work but did not. I did order a new sim and had it ready to test if needed. I called ST the next day and started the process again. This time support said I needed a new sim to support LTE. Support transferred my number to the new sim, used the tfdata apn and now I'm on LTE network. What a great diffferance the speed is., unbelievable. My original sim was about 1 year old. So you should buy a new one to get LTE to function.
