Hello, I have a problem and a question. A friend of mine is visiting me for the upcoming two weeks. It is his first time ever outside europe so HK will be kind of a shock for him :-) I have to work, so I can't take care of him during working hours. Well I heard about a mobile guide called AsK Ting Ting. It combines navigation system, free calls, free internet and works also like a travel guide. My thought is that he can always stay in touch with me, has a good travel guide and never get lost. Has anybody experience with it? I think it could be a good solution, but I would appreciate your opinion and advices. Thank you!
