CellMapper(.net) says the local mast has 5G available. No one with their app has been to that area recently, so there's no data for 5G.
But maps don't tell the full story. For example, Three's 5G is usually fast, but their 4G is slow in some places... what if there's 5G outside, but not indoors?
I recommend testing it yourself. Order a SIM card from Smarty (they're essentially Three, but with monthly contracts), put it on your phone or 5G modem, and check the signal/run some speed tests where you plan to use it. When you're done, cancel the contract (or keep it, Smarty is good if you don't want to do long term contracts).
