PHONE UPGRADE REMINDER
From mid-July, in the lead up to the 3G switch off, you will hear a pre-recorded message and receive
an SMS the first time you make a call on that day.
WHAT TO DO IF YOUR DEVICE IS INCOMPATIBLE
Never fear. A shiny brand new 4G or 5G enabled upgrade is near.
Will my new phone work?
Most 4G and 5G phones will work but before
you go out and buy one, it’s best to confirm the
device you want supports LTE Band 28 (4G 700
MHz) and VoLTE (Voice over LTE), including
VoLTE emergency calling.
Devices other than phones
There are other devices that will be impacted,
and it is up to you to look up the device manual
or contact your supplier. These can include
Smart watches, Personal medial alerts and
loT devices.
