Has anyone successfully connected to ATT using LTE. I have the most recent ROS and have set the APN to broadband. I can get it to connect on 3g, but not LTE. Do we need to mess with Bands?
Switchover from 3G to LTE should happen automatically. Is your SIM card provisioned for LTE? Check it with ATT customers service.
Above assumes LTE signal is present and decently strong (you can verify that using a mobile phone). And assumes LTE band, used by ATT in your area, is supported by your particular LTE card (crosscheck with ATT customers service and spec sheet).
