Save emergency numbers offline
The emergency number in most countries is 112. In Istanbul it is worth checking the local number too. Save these offline before you travel. Emergency calls work on any available network regardless of your HelloRoam data balance.

Best time to visit Istanbul from Ireland
Istanbul is a popular destination for Irish holidaymakers. Dublin Airport has regular direct or connecting flights year-round. The best time to visit depends on your preferences for weather, crowds, and value.

Istanbul Airport (IST) is Turkey's main international hub in northwest Istanbul. It has 4G coverage throughout its single mega-terminal, all concourses, and transit areas. Sabiha Gökçen (SAW) on the Asian side also has 4G. Metro M11 connects Istanbul Airport to the city centre.
The Istanbul Metro, tram (T1 along the historic peninsula), funicular (Tünel), and Marmaray cross-Bosphorus rail all have 4G at stations. Bosphorus ferries (IDO and BUDO) have 4G near both European and Asian piers and for much of the crossing.
The Bosphorus itself has 4G from multiple shore towers throughout the strait. Irish travellers should activate their eSIM before boarding so navigation apps work on arrival.
