Dubai runs on Etisalat's 5G network across every major district. Downtown Dubai around Burj Khalifa, Dubai Mall, and the Dubai Fountain shows consistent 300 to 500 Mbps download speeds on 5G. Dubai Marina, Jumeirah Beach Residence (JBR), and Palm Jumeirah all have strong outdoor and indoor 5G. Dubai International Airport (DXB) has 5G in Terminal 1, Terminal 2, and Terminal 3, so your data is live the moment you clear passport control.
The Dubai Metro Red Line and Green Line both have 4G coverage at all stations and inside the train carriages between stations. Business Bay, DIFC, and City Walk have dense 5G coverage suited for video calls. Old Dubai areas including Deira, Bur Dubai, and the Gold and Spice Souks have reliable 4G with some 5G pockets. Jumeirah, Umm Suqeim, and the beach road corridors have solid outdoor 4G and 5G. The Dubai Frame, Miracle Garden, and Global Village all have good signal at the main visitor areas.
Desert areas just outside the city, including Dubai Safari Park and the Endurance City desert, see signal drop from 5G to 4G. Hatta, Dubai's mountain enclave near the Oman border, has solid 4G at the main resort and wadis but reduced signal on mountain trails. British travellers should check that their handset supports the local network frequencies before travelling.
