Owing to the demand for mobile phones, Gibraltar introduced new number ranges consisting of eight digits, but these could not be dialled directly from Spain. For example, Gibtelecom's pre-paid services consisted of eight digit numbers with the prefix "540", but when using the "9567" prefix from Spain, the last three digits were not recognised, and callers were required to re-enter the eight digit number, during which time they were being charged. However, if the number were dialled from the rest of the world using the +350 code, the call would be terminated in Gibraltar without any problem.
