Saw few people have to buy data sim card from the counter behind the immigration ...
price is about 14sgd ...
to use their data in order to show them your booking itinenary , the data was very weak or non-existence in airport immigration area, not sure why some managed to connect ... while saw few went to buy sim card ...
So important to screenshot your return flight before you clear their customs. I ever once ask them, if i have incoming ticket but planned to stay in VN for a month before going to another country, is that ok? The customs guy says yes.
So i wonder why they often check for our return ticket.
