  1. "Some providers may indicate that they already provide a SIM capable of switching between several networks. This is absolutely true, however, what is not made clear in some cases is that an outage of the MNO with whom the SIM is hosted would mean that the SIM cannot 'lock onto' another network and is in effect rendered incapable of signalling due to an outage of a single supplier." I think many don't realise this; that the 'multisim' type of product can only help with day to day signal strength; not outright network failure. Interesting post as ever Joe, although I can't see manufacturers

  6. J, Very interesting, and covers a lot more than your direct interest. Im assuming you think the final mile (ie the arc) is an easier attack point if its known than the individual site/system. To minimise the exposed footprint from send point to recieve point what would you suggest? Private circuits or VPN's. From the transmission point of view its easier to attack the fixed line (pstn) side than anything else but also the gsm side can be vulnerable. Id of thought that any high grade system based on regular polling would be immune to the reporting (not the attack) but if using an ATS 5 de
