Hey,
So Optus has upped their wireless broadband offering. Works on the 4G network. A good option if you rent or move house alot (i do) as you can move it with you and doesn't require a phoneline.
200GB Wireless broadband -
Month to month - $80/mth (plus cost of modem)
12 month contract - $80/mth (plus $10/mth for 12 months for modem ($120))
24 month contract - $80/mth (free modem)
Also you can get $20/mth off if you bundle with a mobile plan over $30/mth - http://www.optus.com.au/shop/bundles/20-dollar-discount
What i did:
12 month contract -
$36/mth mobile sim only ($40/mth with student discount) -see here https://www.ozbargain.com.au/node/283163
$70/mth 200GB wireless broadband ($20/mth off bundled) including modem free and one month free ($70 credit)
Full cost = Mobile $436 for a year + Broadband $770
note: Up to 12/1 Mbps download/upload in 2300 MHz areas. Up to 5/1 Mbps in other areas. Check your area with their technical support before sign up
Well if imei spoofing is possible then maybe you could use it in a different device
