Well we got cheated by Xiaomi. Any chance of getting the phone to a smartphone electronics service shop and getting the frequency enabled? What's the actual chip that has to be replaced? Where can we find the schematics or datasheets? Any additional info you can provide?

Any chance you have photos of the PCBs?

Do you understand what carrier aggregation is? Do you understand the difference between MIMO communication on HSDPA, single mode HSDPA and LTE-A? Surely by now you must have gottent tired of being in the wrong. You might achieve higher speeds on 3G because of wider channels borrowed from...

So you use Free on 700Mhz and aggregate the 800 MHz band from Bouygees. Check out Wikipedia on Free, France telecommunications, France LTE and then fierce wireless. Oh and almost forgot, check out the list of EU LTE networks on wikipedia, you'll see that I'm right and I will accept your...

Bouygues, Orange and SFR in France use 800 MHz band. Are you in a heavily populated area thus using Band 1,3 or 7? Even the "Free" operator in France uses 800 MHz of other operators in France to supplement their data networks. Google a bit, learn dude, learn. Oh and could you please start...

I checked call quality on a samsung A3 2017 with VoLTE and withoout VoLTE. There's a big difference. I'm getting an average of 0.86 MB/s over HSDPA and over 11 MB/s over LTE in the same region while the spectrum (network) is clear at 4AM. That's megabytes per second, not megabits per second. I...

The lack of Band 20 - 800 MHz 4G support affects phone call quality as most networks in Europe use VoLTE (voice over LTE). Not to mention data connectivity which basically drops you down to HSPA+/HSPA in 99% of regions in Europe. Bad Xiaomi, very bad.

I can't believe that after 4 years of cheap chinese phones flooding the EU market they didn't make phones with the primarily used 4G LTE band 20 in Europe. We got cheated.
