How to block nuisance "PPI" phone calls in the UK

[DM51]

Like a lot of people in the UK, I've been getting a whole lot of nuisance/spam phone calls about PPI insurance etc. These have been both on my landline and mobile. Here's a solution that works:

1. Divert all your landline calls to your mobile

2. On your mobile, go to "Call Settings" > "Call Rejection" and make sure "Auto Reject Mode" is enabled (green I/O slider)

3. When you get a nuisance call, hang up and go to your call log (the options on the top of the phone screen are "Keypad", "Logs", "Favourites", "Contacts"

I've had 3+ a week for months and months. They usually come from a regional code such as 0161 (manchester) etc so this won't work for me.
