Driving through Muscat at sunset as the golden light reflects off the marble exterior of the Sultan Qaboos Grand Mosque is an unforgettable Arabian experience. However, navigating Oman as an international traveler comes with unique local traffic laws, communications restrictions, and payment realities that catch many tourists unprepared.

警察交通規制：汚れた車への10リアル罰金とレンタカー返却手順
Driving a dirty or dusty vehicle in Oman is illegal under Royal Oman Police (ROP) traffic regulations and results in an immediate 10 OMR spot fine. Oman takes pride in public cleanliness, and ROP traffic officers actively issue citations to unwashed cars traveling through Muscat, Nizwa, or along coastal highways. If you rent a 4×4 for off-road excursions in Wahiba Sands or Jebel Shams, your car will collect heavy desert dust.
Before returning your rental vehicle to Muscat International Airport (MCT) or driving back into major city centers, stop at a local manual car wash (known locally as Ghasel Sayarat). For 1 to 2 OMR ($2.60–$5.20 USD), workers will wash and dry the exterior in 10 minutes. Keeping the wash receipt in your glovebox serves as proof of compliance if stopped at an ROP checkpoint.

WhatsApp VoIP規制解除：OmantelおよびOoredooの通信環境
International roaming eSIMs automatically bypass Oman’s strict local VoIP restrictions, enabling seamless WhatsApp and FaceTime calls without a VPN. Oman’s telecommunications authority restricts unapproved internet calling services on local Wi-Fi networks and local physical SIM cards purchased at the airport. Travelers using local SIMs often discover that WhatsApp voice and video calls fail to connect.
Because TravelyData eSIMs route mobile data through international roaming gateways, your internet traffic is treated as international data traffic. This allows unblocked, high-definition WhatsApp calling back home. Furthermore, physical SIM card purchases at Muscat Airport require passport scans and registration queues.
Regarding network coverage, Omantel offers the most reliable signals when exploring remote desert dunes in Wahiba Sands or mountain passes in Jebel Akhdar, while Ooredoo Oman provides fast 5G speeds across Muscat, Sohar, and Salalah.

マスカット空港の配車ハック：Otaxiアプリ vs 高額空港タクシー
Travelers landing at Muscat International Airport (MCT) can reduce taxi fares by over 60% using the local Otaxi app instead of traditional airport taxis. Official airport taxis lined up directly outside the arrivals hall operate on fixed airport tariffs, charging 12 to 15 OMR ($31–$39 USD) for rides into downtown Muscat or Muttrah.
Global ride-hailing apps like Uber do not operate in Oman. Instead, download the local Otaxi app. To avoid airport pickup surcharges, request your ride on Otaxi and walk up to the Departures (Salidas / Upper Level) drop-off ramp to meet your driver. Fares to Muttrah or Ruwi typically drop to 4–6 OMR ($10–$15 USD).
Alternatively, the public Mwasalat bus network operates clean, air-conditioned coaches (Line 1 to Ruwi and Line 8 to Al Khuwair) directly from the airport bus stop for 0.500 to 1.000 OMR ($1.30–$2.60 USD).
スークの現金決済とバイサ単位：買い物マナーとオマーンのホスピタリティ
Traditional markets in Oman operate strictly on physical cash, where 1 Omani Rial (OMR) is divided into 1,000 baisa. While credit cards are widely accepted at modern hotels, gas stations, and hypermarkets (like Lulu or Carrefour), historic bazaars such as Muttrah Souq in Muscat and Nizwa Fort Souq require cash in local currency.
Unlike most world currencies divided into 100 sub-units, the Omani Rial uses a 1,000-baisa system. Banknotes come in 100-baisa, 500-baisa, 1-rial, 5-rial, and 10-rial denominations. When purchasing silver jewelry, frankincense (Luban), or traditional halwa sweets, carrying smaller OMR notes ensures easy transactions.
Omani hospitality (known as Karam) is deeply rooted in local culture. Hosts will frequently offer fresh dates and cardamom-infused Omani coffee (Kahwa). Accepting with your right hand is a sign of respect. For official travel rules, visit the Experience Oman Official Tourism Portal.
