0333 Is The Overall Cheapest Number
There has always been confusion when calling non-geographic numbers about which ones cost more to call.
We use 0300 & 0333 numbers.
These prefixes are charged at local landline rates and it doesn’t matter whether you’re calling from a landline or a mobile phone.
This gives them the advantage over 0800 or 0845 numbers as you are charged for these calls if you’re using a mobile.
