With the SIM you want to use the the phone : 1. Put the phone into Airplane mode (I'm not sure this is needed, but it doesn't hurt) 2. Go to Settings -> About Phone and tap on "Build Number" until it says you are in Developer Mode (~10 times) 3. Go back one menu, and right above About Phone there should now be an option for Developer Options, go into that. 4. Turn on USB Debugging 5. Connect the phone to your computer and type "adb shell" in your CMD window 6. Run the following commands in adb shell : pm clear com.android.providers.telephony settings put global preferred_network_mode 9 settings put global preferred_network_mode1 9 settings put global preferred_network_mode2 9 7. Turn off Airplane mode 8. Power off and Restart the phone 9. Open up the settings app, go to the mobile networks panel, select " Prefered Network Mode" and change it to "4G" 10. Input the appropriate APNs for your specific carrier

多谢大侠,静置一段时间后,自动连上了。请收包子 看来,解药是时间。一切设置好之后,放着,自动会重新连上。估计因为TMO 和Att 同 时提供漫游,手机需要选一条线路。然后再把SIM卡信息传送到Att 或者TMO 国际漫游 数据库比对,这个过程需要连接英国3K服务器,所以就很慢。 请教,您这个操作的中间几行,是对应什么呢? 6. Run the following commands in adb shell : pm clear com.android.providers.telephony settings put global preferred_network_mode 9 settings put global preferred_network_mode1 9 settings put global preferred_network_mode2 9
