Amazon.com = 121.90 USD Inc Tax. (175.31 AUD)
OzzMaker.com = 86.95 USD not taxed (125.00 AUD, which is listed on OzzMaker.com)
Very much cheaper on OzzMaker.com. please let me know if my logic isn't correct.
However there is a long delay in delivery from OzzMaker.com due to COVID-19, it could take up to 4 weeks to arrive in the US. Before COVID-19, it would take about 10 days.
Regarding powering off the GSM, this is just for troubleshooting.
Please send an email to sales @ ozzmaker.com and ill get another sent out to you.
