[Discussion] Redmi Note 7 Global 28LTE Band

According to Global website, Note 7 variant has Band 28 (700Mhz) enabled.

It is currently used in Brazil and many European countries for use of Volte (4G voice call).

Unfortunately this band is not active in my Global Variant (M19017FG) My region and my mobile operator support Volte (Other third-party devices support in my region),

Would be lovely a software update to enable band 28 Really, because I bought the device according to official site so I can use it in my region

Band 28 is not present in this device, unfornately the info in the official site is wrong and frequencies cannot be added through software updates as it is a hardware related limitation.

disagree, all variants of Note7 have the same soc, and even baseband, it would be possible behind software update their activation

The band support is not related to the SoC and there is no Redmi Note 7 variant that truly supports Band 28, like i said before info on the official site is wrong.

Sorry Gonime, it's just a internal sheet from Xiaomi's team. I've never find this model for sale.
