Cafe is one of the classic places to work with your computer hardware "Laptop, Tablet or Phone (3G / 4G)".
In Phnom Penh there are many global chains. Look the pictures links below.
The bandwidth is correct if no many peoples are connected at the same time
(ADSL or Optic Fiber connection). The price of a coffee or juice is 1$ to 5$.
I put here a list of Coffee Wifi place with some information :
Address, Bandwidth, Population, Price, Password
There are of course other places like coffee, restaurant and cake shop not here yet.
When you are present in one of these coffee places and want to test the bandwidth, I recommend
you this website: http://www.speedtest.net
The first icon is an extra about my work inside Coffee Wifi places and a big smile about the security.
