[Q] Can Carriers Change the LTE bands in a Smartphone
We have a nice discussion here at my work.
We are wondering if a carrier company can modify the LTE bands of some smartphones via software (firmware update, eprom mdification or something like that).
For example, our carrier has the same frequencies for CDMA/3G and LTE as Sprint and U.S. Cellular but different LTE bands.
Our LTE band been the number 2 and SPRINT number 25 (I don't know U.S. Cellular LTE Band).
So if is possible for our carrier to get some of these second hands smartphone and with some permission from someone modify the bands or the bands is something done at SOC/Modem Level?
Hope you understand the question.
