Hi I have reset the modem and tried removing the card and reinserting it multiple times. I have tried resetting it with the card in and with the card removed an reinserting it but there is no change....

I've just purchased a MR600 router and a 3 mobile sim contract for internet in my office. The sim works fine in my phone and tablet but when I put it in my MR600, it doesn't connect to the internet....
