Hi All, I just bought a Xiaomi Note from HK and original 3G frequency is set to 900/2100. I live in Canada and carriers use 850/1900 for 3G. I am stuck with 2G which is fine for voice call but internet/Data speed is very slow almost equal to not working. Is there any way to change it? e.g. custom rom, use adb shell, .... etc Any advice is appreciated.
