Baku Heydar Aliyev International Airport

Official Languages: Azerbaijani

English Is Spoken in Hotels, Tourist Sites, and Newer Businesses in Central Baku, but It Is Far Less Common outside the Capital. Russian Remains Widely Understood in Cities from the Soviet Era

Mobile Network: Mobile Coverage Is Strong in Baku and Other Cities, Running on Well-Established 2G, 3G, and 4G Networks, with Commercial 5G Still Limited to Small Pilot Zones in the Capital. Signal and Data Speeds Can Weaken in Mountainous Areas and on Remote Roads

Roaming/SIM/eSIM: Roaming Is Easy for a Short Trip, but Check Your Home Operator Rates First since It Can Be Costly. A Local SIM Offers Good Value for a Longer Stay, but Azerbaijani Law Requires a Locally Bought SIM's Device to Be Registered within 30 Days, or the Phone Is Blocked. That Rule Does Not Apply to Roaming or a Foreign eSIM, so an eSIM on a Compatible, Unlocked Phone Skips Registration and Stays the Simplest Option for Most Visitors

Cards Are Accepted in Hotels, Modern Restaurants, Supermarkets, and Most Businesses in Baku. Cash Still Matters for Taxis, Small Cafes, Local Shops, and Travel outside Major Cities, so Carry Some Manat

Tipping Is Not Compulsory, but It Is Common and Appreciated. In Restaurants, around 5 to 10 Percent Is Typical When a Service Charge Is Not Already Included. Small Tips for Hotel Staff, Drivers, and Guides Are Welcomed for Good Service, and Many Travelers Simply Round Up a Taxi Fare
