A mast was switched off in my area in May, but 3G is still available. They don't tell you when the second mast in your area will be switched off. However my phone is now useless in the warehouse I work in as it only had 3G. In my house I have 4G on full bars, but there's no way of changing this to force 5G even if it's 1 bar. The other networks have 5G indoor coverage in the warehouse. Three need to improve 4G and 5G coverage soon, especially is 3G is all you can get indoors.
