Internal Document▲

Engineering mode on ZTE mobile phones ZTE's mobile phone handsets have the ability to display engineering mode information, which is intended for network engineers' information. For information about enabling engineering mode on some handsets, but you meddle with your phone's settings at your own risk! The following instruction is for the ZTE F8xx series, and other models are similar. Engineering Fields (Fold up the handset to resume) *#06#

Show the IMEI of the handset
