Two operators run the UAE's mobile networks: e& (formerly Etisalat) and du, both regulated by the Telecommunications and Digital Government Regulatory Authority (TDRA). Both report population 5G coverage above 98%, among the highest anywhere, with excellent performance in Dubai, Abu Dhabi and Sharjah — including inside the Dubai Metro and deep into large shopping malls — and speeds that regularly reach several hundred megabits per second. e& has the more extensive rural and desert-interior footprint, reaching further into the Hajar Mountains around Fujairah, the Al Ain desert approaches, and established desert-camp routes near Dubai and Abu Dhabi; further off-track into the Liwa Oasis or deep dune-bashing routes, signal from either network becomes patchier regardless of provider.
SIM and eSIM registration in the UAE is genuinely strict — every line, resident or visitor, is tied to a verified identity under TDRA regulation, with residents using an Emirates ID and visitors a passport, and a limit of two visitor lines per passport per operator. For a short-stay visitor this is a straightforward passport-based process rather than a barrier, and it applies to locally issued lines rather than to a roaming eSIM connecting from an international provider.
The detail that matters more in practice is the UAE's restriction on certain internet voice and video calling: consumer VoIP calling — including WhatsApp voice and video calls, FaceTime, and Skype's call-to-phone-number feature — is restricted at the network level under TDRA policy, and this applies to every connection in the country, not to any particular SIM, eSIM or carrier. Text messaging, photos and voice notes through WhatsApp and similar apps work normally; it is specifically the live voice and video call function that does not connect. Licensed alternatives such as Botim and C'Me work for personal video calling with a paid subscription, and business tools including Zoom, Microsoft Teams and Google Meet are generally permitted and commonly used by business travellers. The practical approach: keep the home SIM active for regular cellular calls and for messaging apps' text function, use the data eSIM for everything else, and plan to use a licensed app, a regular phone call, or a business conferencing tool rather than a WhatsApp or FaceTime call for anything that needs live voice or video.
