Reception dialled in on new phones
It’s that time of the year again when our engineers Ben White and Josh Giumelli take a load of new phones and
antennas out to their test track in remote New South Wales to test reception strength. This time round we saw some
improvements from favourite phones, plus a few disappointing results as well.
Catching some waves: Kondinin Group engineer Ben White tests

BLUE TICK COPS SOME STICK
We test phones on the Telstra Next G
network as that is the most widely used
network in rural areas. Telstra label some of
their handsets with a blue tick logo, which
is supposed to signify those with the highest
reception sensitivity for use in rural and
remote areas.
We have questioned the accuracy of this
blue tick in the past, and this time round
results seem to indicate it is still the case.
How can a blue tick Samsung Galaxy
S10 score the lowest test result of 28km,
while a non-blue tick iPhone XR record a
substantially better result of 33km?
Last year it was a blue tick iPhone 8 which
recorded a paltry 25km, a far cry from the
days of the iPhone 3GS and 4S which could
make calls at almost 40km on the test track.
Buyers who are prepared to use any of the
Telstra-branded blue tick handsets will find
their reception to be strong, and the blue
tick on these handsets, an accurate indicator
of reception strength. But these phones
are not for everyone, as their features,
specifications and build quality are not a
patch on the high-end units.
These handsets often cost less than $100
when purchased outright as a prepaid phone.
They are good value and can potentially be
kept in the ute glovebox for a quick SIM-
swap in an emergency when reception is
needed.
Alternately, fit a high gain antenna to
your vehicle and use it with an approved
mobile phone repeater such as the Cel-Fi
Go. See our antenna test results on page 14
for more information.
SELECTING OUR TEST PHONES
There are so many phone handsets offered
by Telstra that it would be impossible to
test them all, so we have little option but to
use Telstra’s blue tick as a rough guide as to
what to test. We also include a selection of
popular handsets that don’t carry a blue tick,
such as the iPhone models.
There are a range of ultra-large phone
handsets, such as the iPhone and Galaxy
plus models, that retain all of the same
features of their smaller versions, except for
a larger screen and battery.
As it is, the current Galaxy S10 and
iPhone XR and XS have grown in size to
a point where they are hard to fit in your
pocket, especially once they are installed in
a protective case.
No one in their right mind would use one
of these $1500-odd handsets on the farm
without a protective case, which makes the
size of the plus models utterly impactable.
Previous tests have shown near identical
reception performance between standard and
plus-size models, so we have left them on
the shelf. We have also eliminated any other
handsets from the test of a similar size.
