Other numbers beginning with 19 are used for premium-rate SMS services. These were originally trialled using the 188 prefix. These can actually range from a standard SMS cost (usually 25c), up to 55c for competition use, to several dollars for other uses, such as unique bid auctions.All calls to 0198 numbers are a "local call" cost like 13 and 1300 numbers but are used for internet service provider access numbers. They are used both with dial up modems and ISDN.
