Call 09 numbers from abroad.
09s are Premium rate Non-geographic numbers, but usually can be the most expensive. They became available for companies wanting to charge premiums to customers from 1998. Before them were various premium rate prefixes that had a similar position in telecoms such as the most easy to recognize at the time, 0891s and 0898s. There were also 0338s and 0660s. Eventually, in 2001, they were completely removed to be replaced by the novel 09 prefix which was to come in and bring all phone-paid services under one bracket.
