UPDATE [ assuming user will be using phone and perhaps incoming message function only]
Unlocking the phone from the ebay code was no problem.
Amaysim sim worked no issues.
The boost logo will still come up at startup and you will need to delete a few of the boost numbers that will be in the contacts.
It's easy to turn off unwanted apps, I now have the screen totally blank except for the time and the flashlight [torch] on/off button and four icons in the task bar.
The only thing I could not remove to reduce clutter on the screen was the icon on the task bar at the bottom of the screen which takes you to the apps and widgets, it states in the manual it cannot be removed or moved.
You will require a minimum of three icons on the home screen, the phone and the contacts, they can be on the screen or the task bar, the non removable icon that goes to the apps will be in the task bar.
The sim card goes in sideways not straight in as shown in the manual.

For the price, it's not a bad backup phone (I got one from AusPost when they are at this price previously). Just a warning for the users that are looking to root, the model should be rootable but running
adb reboot bootloader
doesn't actually give you fastboot…currently trying to get in touch with ZTE Australia to ask what's up with that/if we can unlock the bootloader (nothing to do with the network unlock code mentioned above).
