Hi Guys,

Is anyone can help Bosch 3000 V2.00 ..acknowledge * key : press and hold on Telstra postpaid sim card.
When the panel is triggered, a domestic call to mobile phone then acknowledge it and will stop calling again.

As for Iphone X iOS 11.2.6 with Telstra postpaid sim card it won`t work. Other service provider sim card such as Optus and Vodafone are work well on Iphone X.
Strange .What is the problem..?
