WiFi exists at the Haram and hotels, but cellular networks become severely congested during peak হজ্জ days — always prepare for offline operation.
WiFi is available at মসজিদুল হারাম (free but slow during peak times), most hotels in মক্কা মুকাররমা and মদীনা মুনাওয়ারা, and some restaurants and shopping centers. The Saudi government has invested significantly in telecom infrastructure for হজ্জ, and 4G/5G coverage from carriers STC, Mobily, and Zain is available throughout the হজ্জ sites.
However, the practical reality during peak হজ্জ 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 মিনা, আরাফাত, and মুযদালিফা. Sending a simple text message can take multiple attempts, and data-heavy applications become essentially unusable. This is why ইহরামOS is built with an offline-first architecture — all ritual guidance, dua 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 হজ্জ days begin.
