Running out of Numbers

In Hong Kong, whether you're 7 or 90, everybody has a cell phone. They come in all different models, from the black-and-white Nokias to the newest Sony Ericsson 5.0 megapixel camera phone. You must think that a lot of phones are needed for Hong Kong's 7 million population, and problems may occur, currently, HK is suffering a crisis with phone usage. The problem is not the phones itself, it's the phone numbers, Hong Kong is running out of phone numbers rapidly. All phone numbers in the region currently either 6XXXXXXX or 9XXXXXXX, but now, phone operators are running out of numbers and are pleading for a number starting with 5 or even extending the numerals to 9. In the future, I'll be able to get lots of money for my phone number :P.
