Hello,

I bought (this is my first Xiaomi purchase) a Mi 11 special edition. I haven't received it yet, but I think I made a mistake. During the purchase I checked that it was compatible with bands frequency in France. My telephone company uses the B28 700 MHz band. It was indeed valid on the Kimovil site. Since the announcement of the Global version, an update has been made on Kimovil with the incompatibility of the 700 Mhz B28b band. The 700 Mhz B28a band would remain functional. After some research I found that this is the band used by my operator en France (Free Mobile).
I don't want to change operator because it is my job line.
I can't find any official information on this so I would like to have your opinion.

Thanks for your feedback.
Shayne

The band B28 is divided into 2 parts, A and B :
  • 28A : 703–718 MHz (Uplink) and 758–773 MHz (Downlink)
  • 28B : 718–748 MHz (Uplink) and 773–803 MHz (Downlink)
The GSM Arena site doesn't mention this specificity. The Mi 11 wouldn't work on the B band.

Hi,

I have installed the global rom V12.0.3.0.RKBEUXM and the phone is OK but the band B28b is KO. I have compared with a mi 11 original global.

Thanks for your help.

I wrote that it corresponds to Band 28B, but it was a mistake.
(Ultra was compatible with both Band 28a / b. Mi 11 not.)
