Should I just buy a local SIM at Muscat International Airport instead?

Buying a local SIM at Muscat airport is straightforward — Omantel, Ooredoo, and Vodafone Oman all run kiosks in the arrivals hall with passport-only registration and English-speaking staff. Two practical issues: airport SIM kiosks don't operate 24 hours like in Amman, and many shops in Oman close on Friday mornings for prayers, which complicates getting a SIM if you arrive late or land on a Friday. The ETravelSim Oman eSIM installs at home before you fly, connects the moment your plane lands, and avoids both problems.
