For a typical 7-day Oman road trip covering Muscat, Nizwa, Wahiba Sands, and Sur, 5 GB is enough for most travelers. A 10 to 14-day trip adding Salalah and Jebel Akhdar with daily Google Maps, WhatsApp, and casual photo uploads usually needs 10 GB to 20 GB. Heavy users uploading desert and mountain videos or working remotely should pick 50 GB or unlimited. Long drives consume more navigation data than expected, so road trip itineraries skew higher.
