I reserved a restaurant at the Hong Kong Hotel. Why can't my mobile phone number be used?

As Hong Kong tourists come from all over the world, generally speaking, Hong Kong restaurants only accept local number reservation service in order to avoid malicious reservation or high national call charges caused by restaurant dialing back numbers. If it is not a busy time, there is generally no need to locate (that is, outside lunch and dinner time). If you must make a reservation, it is recommended to buy a local calling card 7- 1 1, generally 60- 100 Hong Kong dollars, so that you can have a local number, which can be used to book a restaurant, and the phone bill inside can also be used to surf the Internet or call your family.
