Just placed an order for S Line (upgrading from my 2012 model). I've opted for the tech pack this time. I've just got a couple questions about the 4g wifi and phone box.

Firstly, I'm right in thinking I can put my EE sim card in the sim tray? I have a MIFI device from EE which is normally in my car. I'm assuming the 4g/LTE modem in the MMI is connected to an external aerial - boasting the 4g signal?

The tech pack comes with Phone Box - which the dealer confused me about. The sales guy said the phone box will boast the phone signal ( again assuming it connects to an external aerial), then he tells me the Audi Connect system uses my phone to push wifi around the car.....So I mention the fact I have an EE sim... he then looks confused and tells me I wont need the SIM card!!

I will need it, I want to use it! I have 15gb on my EE sim and only 1gb on my iphone contract.

So in short, I want to use my EE sim for car data (Audi Connect/google maps etc) and sharing wifi around the car for mrs and kids. I also want to boast the signal of my iphone.

Does the tech pack do all this?

Thanks in advance folks.
