WiFi exists at the Haram and hotels, but cellular networks become severely congested during peak حج days — always prepare for offline operation.
WiFi is available at مسجد الحرام (free but slow during peak times), most hotels in مکہ مکرمہ and مدینہ منورہ, and some restaurants and shopping centers. The Saudi government has invested significantly in telecom infrastructure for حج, and 4G/5G coverage from carriers STC, Mobily, and Zain is available throughout the حج sites.
However, the practical reality during peak حج days (8th-13th of Dhul Hijjah) is that cellular networks become severely congested when 2+ million people are concentrated in the relatively small areas of منیٰ, عرفات, and مزدلفہ. Sending a simple text message can take multiple attempts, and data-heavy applications become essentially unusable. This is why احرامOS is built with an offline-first architecture — all ritual guidance, دعا content, and safety features work without any internet connection. Download all necessary content, maps, and app data while you have reliable WiFi at your hotel before the حج days begin.
