Forget roaming from Russian operators — it's an expensive relic. Today you have two simple, working options, and the choice depends on your trip. Option 1 — a local SIM: on arrival you find a local operator's counter (Turkcell, AIS, Dialog, etc.), buy a SIM and insert it. Pros: the cheapest data, lots of gigabytes for little money, stable. Cons: time to buy and activate (sometimes with the seller's help); not worth it for a short trip. Best for: trips of a week or more in one country needing constant fast internet. Option 2 — an eSIM (virtual SIM): you buy a data pack online before departure in an app (Airalo, Nomad), activate it on your phone (most modern models support it), and land with internet already working. Pros: maximum convenience, works from the moment you land, no office hunt or physical swap, ideal for multi-country routes (buy a regional pack). Cons: a bit pricier than a local SIM, and your phone must support eSIM. Best for: short trips (3–10 days), multi-country routes, and anyone valuing time over the lowest price. Simple rule: going long to one country and want to save? → local SIM. Short trip, several countries, or don't want the hassle? → eSIM. Being connected abroad is basic comfort, not a luxury — spend 10 minutes before the trip setting up an eSIM, or know where to buy a local SIM at the airport.
