No, roaming in Azerbaijan with most EU, UK, or US mobile plans is not free and typically incurs significant charges.
Unlike within the EU, "roam like at home" policies do not extend to Azerbaijan. You can expect high per-megabyte data rates, expensive calls, and costly SMS messages, which can quickly lead to a large bill, especially if you rely on your phone for navigation or streaming in cities like Baku.
To avoid these unexpected expenses, consider using an eSIM for your trip. An eSIM provides local data connectivity at much more affordable rates, allowing you to stay connected for maps, ride-hailing apps like Bolt or Uber in Baku, and communicating with friends and family without worrying about excessive roaming fees. Your eSIM will automatically connect to the strongest available major network upon arrival at Heydar Aliyev International Airport (GYD) or elsewhere in the country.
