If you have a Sim based tracker then you may need to switch service provider. The cheap self fit trackers are either 2G or 3G based. If you are not on O2 or linked service provider (eg GiffGaff) then it would be prudent to switch to one. Of the 4 network providers, EE are certainly switching 3G off in early 2024. It looks like O2 will keep 3G going until 2033 as they are the carrier for 2G based Smart Meters. The other 2 (Vodafone and 3) are sure to follow EE’s switch off. https://www.4g.co.uk/news/networks-using-o2/ Alternatively, switch to a 4G based tracker. They are available on the likes of eBay.
Vodafone are starting the switch off, 2 towns so far, can’t say which so don’t ask me! They currently pay my bills
100%. I wondered why my gates stopped working (sim based). Had to buy a new 4G module. Nothing £840 couldn’t fix…
They aren’t switching off 3G in areas where there isn’t suitable 4G/5G coverage, so you should be okay.
