I picked up an LTE sim card from a local store. I had it cut into a microsim and inserted it into the lumia 900. I changed the apn to what you told me and the phone worked perfectly! Thank you for all your help. Much appreciated.
Hi! Glad to hear that LTE is working on your lumia. Did you just pick up an LTE sim card and everything was good to go? I have a Lumia as well and would love to have LTE running. Thanks!
