Honestly, I work for an iot Mobile network provider, the amount of devices that will brick if 2G will be turned off is massive. Especially the cheaper ones that only have 2G/3G modems on board. And not only are they the most likely to brick, but also the most unlikely to be fixed.

I see this sort of thing all the time.

There's a disconnect between the time scales for industrial equipment and the time scales for IT and telecommunications. A PLC running a factory might last 30 years, but the software to program and troubleshoot it won't run on modern operating systems or computers. The company doesn't want to spend hundreds of thousands of dollars to upgrade it when there's nothing wrong with it.

Same with telecommunications - POTS worked for a century, and over the last decade we've seen it largely disappear, which makes fire alarm panels everywhere inoperative. We recently ran into an issue where a fire marshall refused to allow anything but POTS and all of the non-end-of-life hardware only supported IP.

Not so smart now are they

This is the best summary I could come up with:

The report echoes an earlier one by the National Audit Office (NAO), which found that as of March 2023, energy companies had rolled out the devices to just 57 percent (roughly 32.4 million out of a potential install base of 57.1 million) homes and businesses.

It asks both to set out "what they will do to ensure suppliers assign more importance than at present to replacing those smart meters not functioning properly" and "a timetable for replacing the communication hub element of smart meters that will lose functionality when the 2G and 3G mobile networks are switched off."

It is hardly surprising the PAC, which studies public audits such as those written by the NAO, is concerned about deadlines because the smart meter project has missed plenty so far.

The scheme started in 2012 when government placed the legal burden on energy suppliers to ensure they'd complete the smart meter rollout by 2019.

The PAC also want DESNZ and Ofgem to outline "measures to ensure that suppliers use future-proofed technology – for example, by excluding 2G or 3G connectivity – in all new smart meter installations."

And it wants the department and the energy watchdog to detail program costs to Parliament on an annual basis to inform decisions about the rollout.

Is the primary reason 2g is insecure and 3g has phat channels?
