Each message costs 25p (including VAT) to the following networks: Vodafone, Orange, O2 and T-Mobile.

These costs will be charged to your normal phone bill or deducted from your available credit balance for pay-as-you-go customers. If you are a pay-as-you-go customer, then you must make sure that you have sufficient credit in your account.

If for three weeks running we find that your pay-as-you-go account has insufficient credit, we will cancel your alert services. You will not be able to renew your official alert services on a barred number.

Credit card and direct debit subscribers will continue to be charged at their monthly or quarterly amounts.
