Xiaomi Unlock: solve SMS not sending error

Creation date:

Latest change:

The first thing you should do after buying a new Android phone, is to unlock the bootloader, as it may take some time to accomplish it and may be easier while it is a new newer phone (more support). The problem starts when there are companies like Xiaomi that do not want you to unlock your device; in this case, to unlock a Xiaomi device, you need a SIM card, a phone number and an account with them and after requesting the unlock, you my have to wait around 30 days. The worst part is that the Xiaomi unlock utility, requires you to verify your phone number through SMS but THEY WILL NOT SEND YOU ANY SMS! (see examples in the XDA forum or the Xiaomi Forum.

What worked for me was the following:

  1. Install the new Xiaomi unlock.
  2. Log in in xiaomi.com with the QR code; this will verify your phone and will send a SMS that actually works and thus, deactivate the SMS verification requirement for a while (because you have already verified the device you are using to log in).
  3. Log in the Xiaomi Unlock Tool and you should be free to go.
