Yes, in most tourist-oriented countries the arrivals hall has SIM options: dedicated telecom counters run by the major carriers, general kiosks selling multiple brands, and sometimes vending machines dispensing tourist SIMs. Staff at carrier counters typically speak English, handle the registration paperwork with your passport on the spot, and set up the APN so you walk away working, which is genuinely worth something after a long flight.
The premium over city prices varies, sometimes trivial, sometimes noticeable, and airport counters usually push their bundled tourist packages rather than the cheaper plans available in town. Whether that matters depends on your trip: for a short visit, the convenience of immediate connectivity for ride-hailing and maps easily justifies a small markup; for a long stay, grab the minimal option or use free airport wifi and buy properly in the city.
