This message is for anyone either with an existing Smart Meter, or anyone thinking of getting one. What the government and all the fuel providers haven't told customers, is that because all Smart Meters use the much older 2G and 3G mobile phone networks to send meter readings, and that 5G mobile networks are being gradually phased in, with 4G as a backup, witnin the next 2 to 3 years, the 2G and 3G mobile networks will be switched off permanently, rendering all Smart Meters unable to function. The fuel providers won't upgrade their Smart Meters either, because it will be much too expensive for them, to keep replacing the Smart Meters every few years. Also, people living in rural area will likely have the most problems with existing Smart Meters, due to weak mobile signals.
This situation wasn't foreseen by the government 5 years ago, as 4G had only just been started on, and there were no existing plans to switch off the 2G and 3G mobile phone networks. The 2G and 3G mobile phone networks are being switched off, because very few customers will be using them in 2-3 years time, so the mobile phone networks won't be running an older technology for a minority of customers, due to cost.
I have over 30 years experience of using technology and working in I.T, and while I don't consider myself an expert, I do have an advanced understanding of this.
