In China, it's not enough for a tourist to just take a smartphone.
It needs to have internet, payment, maps, a translator, and at least one means of communication set up in advance.
In the UAE, a phone is needed almost immediately: to open a map, call a taxi, pay for a ride, find a hotel, check a reservation, contact a transfer, and build a route on the metro. But there is a nuance: in the Emirates, not everything on the phone works the same way as at home.
In Turkey, tourists often need not an "ideal suitcase," but a properly prepared phone.
