Can I switch/select cell bands (LTE/3G/Etc) on the S4 /ATT/i337?

[Anakha6910]

I can access the band selection page, but everytime i try to select an LTE band, my phone refuses to accept it and defaults back to the previous selection.

Any ideas before i try to root my phone?

Thank you. I have an AT&T phone as well and I used the code you gave and the code worked. I still have to figure out how to get the data plan to be accepted though.

How do I save the information once I have selected the network type? I have selected and enabled then turn off and restart the phone but it keeps returning to what it was before.

I have a Galaxy S6 SM-G920A (AT&T mobile from USA). I bought it three month ago in Cuba, where I live. So I can´t connect to 3G local service because my phone doesn´t have 900 MHz frecuency for 3G (that is the local frecuency of my network provider for 3G). I wondering if I can flash my phone to other band (Europe band or Jappanesse band) which have 900 Mhz for 3G and as a result to get the holly network type of my provider. Would someone like answer me please???? Sorry for my English, it is not my mother language. My email is eric.rey@ucm.pri.sld.cu or ericrey1996@gmail.com Please someone answer me. I need it. Greetings from Cuba.
