Hi,
I am a first time traveller to Shenzhen and I have no knowledge of mandarin
Can any one help me on the following.
1) How do I get to Shenzhen from HongKong- safest way and what do I need to look out for-tips
2) When I arrive in Shenzhen, where will I be getting off- which station and tips on taking a taxi to my hotel.
3) Can I get a prepaid sim for my mobile and a wireless broadband for me at the Shenzhen port where I arrive and where exactly would I need to go.

Any other first time travel tips would be a great help
Thanks
Sam
