Mobile phones have an in-built lock code. This is especially important for security purposes and to protect the phone from unauthorised as well as unwanted access. In the case of Chinese mobile Eiroga E71, such a lock code exists. It may be that while changing security settings, the user is asked to key in this phone code. If the user is unaware of this code, it may cause inconvenience. The manual of the phone generally provides a solution to this, or one can use the default code that is given below. Mobile telephony has made life user-friendly.
I recently purchased an Eiroga E71 chinese mobile, and when I try to edit the security settings, I'm prompted to enter the phone code.
You can also consult the manual of your phone, but if it is not found then you can use this one:
By default code is: 1122
