Best way to go if your considering buying one of these outright, tablet on its own for cellular model is roughly $1697 so for an extra $91 you get 4gb data pm, $1788 over 12months, 24month contract $79pm $1896 total, 4gb data pm from what ive seen is $30pm on its own, other 12m 24m options available with more or less gb
Other Options:
2.5gb 12m = $1752
24m = $1824
8gb 12m = $1932
24m = $2184
12gb 12m = $2064
24m = $2448
Nice to see an Op actually do the maths. Thanks Op good find. But I might go Telstra as their coverage is better in far SE Vic
