Turn off the device and insert a SIM card from a different network. Power the device back on.
: Be careful; most ZTE phones only allow a limited number of attempts (usually 5 or 10) to enter the unlock code before the phone permanently locks to the original network.
No. Different firmware versions (e.g., B02, B05, B07) use different cryptographic salts. A calculator coded for B02 will give wrong codes for B07.
Unlike older Nokia or Samsung phones from the early 2000s, which had publicly leaked algorithms, ZTE updates its security protocols with each firmware version. A calculator that worked for a ZTE SFR 101 from 2015 will likely fail for a later model.
