Live in Spain, moving to Argentina. Buy a new Xiaomi MI A1, on the website it lists support to LTE B4 (main band in Argentina).
Get the phone, open the box which says GLOBAL Version, but user manual's LTE band support list does not say B4.
I ask XIAOMI, the reply is "ignore the manual" (see screenshot, in spanish but pretty clear)
Any way to know which info to rely on? I will send it back if it does not support B4.
