Have you got good mobile signal. Probably not, sorry.
Anyway, just in case, have a look at 3 broadband.
We had endless problems with cabled broadband. Moved to 3 and have to admit it is very good here. Their help desk is typical.
But not too expensive.
Irony was that we had a dispute with them over mobile roaming abroad and left them for our phones.
Thanks - 3/Three reception used to be pretty poor in the Calder Valley but I just looked at their coverage checker and that suggested that I would now get a good 4G signal indoors here. No 5G at the moment though.
I was going to look at some of the deals on Three but the website just went down for maintenance! (I'll watch some TV then check again before going to bed...)
Three coverage is poor in many of the rural areas that I cycle round but my current network (Giffgaff on O2) is almost as bad, though great here in the valley.
I currently pay £6 a month for 2 GB data and unlimited calls/texts on mobile, plus about £21 for my Plusnet broadband (and unused landline phone) but that will go up by a few pounds soon and would cost more still when fibre comes along.
I get 16 Mb/s download which is ok-ish for my normal use but I hope to get a 4k TV soon and it wouldn't be fast enough for that. I also find upload speeds painfully slow at about 0.7 Mb/s.
I'd feel slightly insecure getting everything through one company though. If I lost Three broadband for some reason then that would also be my phone and email down too. How reliable have you found them and what speeds did you get, assuming that you were on 4G rather than 5G? I would want 16+ Mb/s during the day and 35+ Mb/s for 4k streaming after (say) 10 pm.
