最近看到有些朋友从客服得到了SX1的解锁码，却还是出现解锁失败的情况，我分析这里有几种情况导致问题：
最大的可能是在解锁时输入解锁码出错，
第二种情况，由于IMEI号码比较长，容易打错，可能你在发送email填写自己机身IMEI码时出错，从而造成“连环错”，客服提供的解锁码当然就不对，
最不可能的一种情况就是客服提供的解锁码是无效的。
对此，我整理了一下西门子澳洲客服回信中提示用户注意的解锁要领，希望对大家顺利解锁有帮助。
回信原文：To unlock your handset, please do the following:
1.Remove your Sim card and switch on your handset.
2.Once you switch on your handset, the display would show "insert sim card. Enter the master code.
3.A "Please wait" message will after you press on the last "#" symbol of the mastercode provided.
4.If you have successfully unlock your handset, it should display "phone code deleted!" However, should you encounter "Incorrect!
Please wait" or "Invalid Entry!, you have to switch the phone off and try again.
Note: If you entered the mastercode incorrectly, it would take longer than usual to unlock the phone because the turnaround time
would increase exponentially. Your best bet is to switch off the phone and try to key in that mastercode next day.
I suggest that you maintain a copy of both the Master Code on a piece of paper for your own reference in the future.
其中提到的解锁要领：
1，取下SIM卡，开机
2，开机后，屏幕显示“插入SIM卡，输入解锁码”
3，当你输入完解锁码最后一个“＃”号，会显示“请稍候”
4，如果解锁成功，会显示“安全码已经删除”，但如果显示“错误！请稍等”或“输入错误”，那您只能关机并重新尝试了。
注意：如果你输入错误的解锁码，之后的解锁时间将比通常要更长，因为复位时间将程曲线增长。这时您最好关机并隔天在尝试输入以上解锁码。
建议您在一张纸上记录下这个解锁码，以备日后不时之需。
