Replace The Sim Card - Zte AT&T Velocity MF923 User Manual

Once an update becomes available, you can load it immediately
or postpone installation for up to 12 hours. After 12 hours, the
update installs automatically.
On the mobile hotspot:
If you read an alert indicating an update is available, you can
choose to update now or postpone. Go to step 5.
If you want to check for updates manually, from the home
screen, tap Settings.
Tap AT&T Software Update.
Tap Check for update.
If an update is available, the software will be downloaded and
provide 2 options if it is not a critical update:
• Tap Reboot & install to load the update immediately, or
• Tap Remind me later to wait for 4 hours. An alert will appear
after 4 hours reminding you that the update is available.
Note: If the update is critical, you will only have the option to
Reboot & install.
If you are updating now, a message will appear if your mobile
hotspot's battery is low. Plug your mobile hotspot into your
wall charger, and then tap Begin. (This ensures the update
will complete without the device shutting off midway through
the update.)
