Hello there, I've been to Hong Kong for 4 days. All along, I've gathered many useful tricks for those who wish to survive there. As for the starter, all you need is the
octopus card.

You need this card, and all your journey will be easier, purchase this card before you leave the Hong Kong International Airport. With this card you will be riding
MTR and
Tram. As for me, my destination was at Wan Chai passing Kowloon. (TIPS: Purchase this card at the
airport counter, dont take the octopus card offered on plane. This card only cost you
HKD 150, HKD 50 deposit, and you can reload this card at any
MTR station and at any
7 Eleven stores)
And the next critical thing that you need to purchase is the
Traveler's Sim Card, remember when you touchdown at the airport, make sure to rush to
Level 7 and you may find a
'1010 store' and state that you want a sim card for travellers, and the workers there will assist you from A to Z. I purchased the
HKD 88 sim card, which gave me 7 days unlimited internet subscription. (TRICKS: Be careful not to be tricked from other store that located somewhere level 5 which offer you
HKD 288 sim card that have the exact service as the one I purchased at 1010 store)

TIPS: If you are travelling in group and you think you need to access internet, plus you really need to save your budget; just purchase only one traveler's sim card and then tether to your members by setting your hotspot connection.To muslims, at the Hong Kong International Airport, you may find
Halal Food served at
Popeye.
May this entry helps you.
