How good is the mobile data coverage on UAE desert and mountain roads?

Mobile data coverage in the UAE is excellent in cities and along major highways between Dubai, Abu Dhabi, Sharjah, Ajman, and Ras Al Khaimah. On popular routes like the Hatta road trip from Dubai or the Jebel Jais mountain road in Ras Al Khaimah, you can usually expect strong 4G and, in many areas, 5G coverage from leading networks. However, coverage can become patchy when you leave paved roads for deep desert tracks, remote wadis, or very isolated camping areas. For those situations, it’s smart to download offline maps in advance, share your planned route with someone at your hotel, and avoid venturing far off-road without a guide or proper equipment.
