To be honest, I'm looking at sim only contracts now as it looks more
economic than the rip off pay as you go anyway. I could then even use the
Amazon Echo for calls.

Umm.. They will still find a way to bump up the monthly charge:-(

Vodafone (because they have a reasonable signal strength. Even Madeira!)
Fixed price sim only contract around £8.50/month. Unlimited texts and
300minutes free calls with 250MB data plus global roaming has now crept
up to £12.50 under various subterfuges.

Discontinued discount, extra data charge (I don't use data!) etc.
