Outside the United States, premium short messages are increasingly being used for "real-world" services. For example, some vending machines now allow payment by sending a premium-rated short message, so that the cost of the item bought is added to the user's phone bill or subtracted from the user's prepaid credits. Recently, premium messaging companies have come under fire from consumer groups due to a large number of consumers racking up huge phone bills. A new type of free-premium or hybrid-premium content has emerged with the launch of text-service websites. These sites allow registered users to receive free text messages when items they are interested in go on sale, or when new items are introduced. An alternative to inbound SMS is based on long numbers (international mobile number format, ., +44 7624 805000, or geographic numbers that can handle voice and SMS, ., 01133203040  ), which can be used in place of short codes or premium-rated short messages for SMS reception in several applications, such as TV voting, product promotions, and campaigns. Long numbers are internationally available, as well as enabling businesses to have their own number, rather than short codes, which are usually shared across a lot of brands. Additionally, Long numbers are non-premium inbound numbers.
