Ultra fast? That would be nice. We don't even have a decent 2G mobile phone connection in a lot of the village. We can only get voice calls upstairs and still need a landline. Poor/non-existent mobile internet at home - No 3G, rare 4G. People in Norwich are currently using 5G and are getting Gigabit internet installed....
I wouldn't call it "ultra fast" but I've just had Starlink installed. Low orbit satellite internet from SpaceX.
I'm getting speeds of up to 200 Mbps
Its night and day from the 2-3 Mbps from BT ADSL
No 4G here and mobile reception is useless on every network so I need some kind of landline to make and receive calls. I've setup a VOIP SIP trunk which costs me £5 a month with 500 minutes inclusive and works over the Starlink connection. Both the call quality and the Starlink connection work flawlessly with no dropouts etc. Only been in use for a month or so but can't recommend it enough.
