澳洲3G关闭后手机解决方案-小米

3G网关了以后部分安卓手机变砖。个人亲测了一个解决方案和大家分享。我的手机是小米的。
1. 卡插里，先用拨号盘输入*#*#86583#*#* 输完之后手机应该显示carrier volte check disabled. 如果显示的是enabled, 就再输一遍，直到显示disabled.
2. 再输入*#*#869434#*#*  输完后手机显示carrier check vowifi disabled.
3. 再去settings->simcard & network 里打开volte就可以了。
  1. To begin with, you will have to disable the carrier check for VoLTE. So bring up the dialer and type this command: *#*#86583#*#*
  2. After that, you will need to disable the carrier check for VoWiFi. So bring up the dialer again and type this command: *#*#869434#*#*
  3. Now head over to Settings > SIM and Cellular and select your SIM Card.
  4. Then scroll to the end and enable the toggle next to VoLTE and VoWiFi.
