Xiaomi mostly dont support 4g+ aka m'sia interband CA.

xiaomi phone intraband CA example digi b3,b7 & b8
example of intraband ca (kahwin sama janda) not availble in m'sia
b3+b3, b7+b7 or b8+b8 CA

m'sia current interband CA only.
like only b3+b7 CA for digi. so xiaomi phone cant run it even cat xx phone.

VoLTE xiaomi phone support.... it has nothiing to do with CA/LTE-A things.

then even honor phone/huawei budget phone like honor play, honor8x n etc also not support CA...even CATxx phone
