Use a Samsung tablet that is brand new, or that was reset to the way it left the store. It cannot be an iPad.
- Put the SIM card in the tablet and turn it on.
- The tablet shows its first screen. Tap an empty part of that screen 6 times. A camera opens.
- Hold the tablet so its camera sees this square.

The tablet now gets the bus app by itself. Press Next when it asks. This takes a few minutes.
- The tablet asks for 6 numbers. Type and press Connect. These numbers work for minutes.
Done. The tablet now shows only the bus screen. It updates by itself.
Does the tablet have the bus app already? Then only do step 4.
