What's included, when it starts, and how to get connected.
Istanbul's trams, metro, buses and ferries all run on the Istanbulkart. Buy one from the yellow machines at the airport metro or any major station, load it with cash or card, and tap on each ride. One card can be used for more than one person by tapping again. Single-ride tickets exist but cost more per trip.
Contactless cards work in most shops, restaurants and taxis in cities. Small bakeries, bazaar stalls and dolmuş minibuses often want cash. ATMs are common; your bank may charge a foreign withdrawal fee.
The Blue Mosque and other working mosques close to visitors during prayer times and for longer at Friday midday prayers. Hagia Sophia has a separate visitor entrance and ticket for tourists; check current arrangements before you go.
Türkiye asks visitors to register phones that use a Turkish SIM for a long stay. onesim connects through Turkish partner networks as a roaming eSIM, so for a normal trip there is nothing to register. If you are staying for months, check the current rules on device registration.
Istanbul Airport sits well outside the city. The M11 metro runs to Gayrettepe and Kağıthane, where you change for the rest of the network; Havaist buses go to Taksim and Sultanahmet. Sabiha Gökçen on the Asian side has its own M4 metro link.
Turn on the onesim line for mobile data before you leave the terminal: maps, ride-hailing and the Istanbulkart app all work from the first minute.

About 1,900 km from Munich to Istanbul. The two routes, every vignette and toll at 2026 prices, what the EES means at the border, and Türkiye's new rule for foreign plates with unpaid tolls.

Answers about data, coverage and setup for Türkiye.
Coverage follows the local networks wherever they reach — cities, transport corridors and most rural areas. Remote mountain and island areas can have weaker signal on any carrier.
No. onesim is installed before you travel, with nothing to register when you land. Turn on the onesim line for mobile data and you are connected.
Installing the eSIM does not start the clock. Your package starts the first time the eSIM connects to a network in a country it covers, even while mobile data is off. Install at home over Wi-Fi and keep the onesim line switched off until you arrive; if your home country is covered too, the package would start the moment the line connects there.
Yes. Your account has one onesim eSIM, and you refill it with any regional package from anywhere in the world — from the website or the app. The new package is added to the eSIM already on your phone; there is nothing to install again.
