This is correct in the UK; hospital pagers, domestic smart meters for water and electricity, signalling systems for traffic monitoring and remotely controlled street lighting all use 2G because of the low power and bandwidth requirements. It is likely that 3G will be turned off before 2G here, which may still persist for many years to come until all of this essential public tech has been upgraded. GSM has been here in the UK since analogue mobile telephony was replaced and has been the dominant technology ever since. Everybody keeps talking now about 5G and how wonderful it is, and indeed my iphone 12 is 5G capable - its just that there is almost no reliable 5G coverage anywhere in the UK except in a very small number of large cities. If you live in the country you’re lucky if you can get reliable 4G coverage!
