Current network usage

It is no longer possible to tell the operator of a UK mobile phone from its number alone, as customers are free to take their number with them when they change networks.

Although the number ranges listed above will have originally been used for Three services, there is no reliable way of telling which network an individual mobile phone number is currently associated with.

Call charges

These are mobile phone numbers and should usually be charged at standard rates.
