What Reunion data
actually costs in 2026.
A detailed price comparison across eSIM, airport SIM, pocket WiFi, and carrier roaming for Reunion.
A travel eSIM for Reunion starts at $3.67 for a 7-day plan. Airport SIM cards vary in price depending on the carrier and data included.
When comparing total trip cost, an eSIM is the lowest-cost option for data in Reunion for most travelers. There is no deposit, no return process, and no risk of losing a physical card.
Airport SIM reality
in Reunion.
What actually happens when you land and need connectivity. Real wait times, real costs, and what to expect at the counter.
Airport SIM cards at the main international airport cost more than online rates for 7 days — a 25-minute queue required. Local carriers operate kiosks in the arrivals hall. Tourist SIM prices at the airport vary but are generally higher than street rates due to the captive location.
Queue times at arrival peak hours can exceed 30 minutes. Passport registration is not required for tourist SIMs in Reunion, which speeds up the counter transaction. Compare that against an eSIM: $3.67 for 7 days, purchased online in 2 minutes before you fly, with no queue and no counter.
The airport SIM counter operates in a captive environment — travelers who land without connectivity have no choice but to buy there or wait until they reach a city-center store. eSIM eliminates that dependency entirely. If you need a local Reunion phone number for apps like ride-hailing or food delivery, the airport SIM does provide one.
For data-only needs — maps, messaging, browsing — the eSIM wins on every metric.
WiFi in Reunion:
what travelers find.
Public WiFi coverage shapes how much you actually need a cellular plan. Here is the honest picture for Reunion.
WiFi coverage in Reunion's urban areas is uneven — cellular eSIM provides the consistent private access public networks cannot guarantee. Major hotels and international chains offer reliable connections, but street-level and public WiFi is inconsistent. Travelers planning an itinerary beyond the capital or main resort areas should not rely on WiFi as their primary connectivity source.
A cellular eSIM provides consistent data throughout Reunion without depending on venue WiFi. Use hotel WiFi for downloads; use eSIM for navigation and real-time connectivity.

What Is an eSIM for Reunion?
An eSIM for Reunion is a digital SIM card built into your phone — no plastic card, no airport queue. You purchase a plan online, scan a QR code, and connect to networks like Orange RE the moment you land. Your home number stays active on the other SIM slot, so you receive calls and texts while using local data. Setup takes under 2 minutes and works with any eSIM-compatible phone.
SIM registration requirements are common across Africa. Nigeria, South Africa, Kenya, Egypt, and most North African countries require passport registration. The process adds 10 to 30 minutes at the counter depending on the country. eSIM avoids this paperwork entirely.
Data costs in Africa follow a wide range. South Africa and Kenya offer competitive rates under $5 per week. Central African countries and island nations can charge $15 to $25 for similar data volumes. Check country-specific pricing before choosing between eSIM and local SIM.

Reunion: eSIM vs SIM
vs WiFi questions.
Does Reunion require ID registration when buying a SIM card?
Most SIM vendors in Reunion ask for a passport or government ID at the point of sale. The exact enforcement varies by carrier and location. At airport counters, expect to present your passport. eSIM bypasses this entirely: no document exchange, no counter interaction, and no registration delay. eSIM plans for Reunion start at $3.67 for 7 days.
Which carrier has the best coverage in Reunion?
Orange RE provides the widest coverage network in Reunion, followed by SFR. Travel eSIM providers typically partner with one of the top two carriers, so eSIM users get the same tower access as local SIM buyers. Both formats deliver identical speeds on the same network.
Is carrier roaming cheaper than eSIM for a short trip to Reunion?
Only for stays of 1 to 2 days where convenience outweighs cost. Major US carriers charge $10 to $12 per day for international roaming passes in Reunion, which totals N/A for a 7-day trip. A travel eSIM covers the same 7 days at $3.67. For any stay beyond 48 hours, the eSIM is substantially cheaper. Roaming also throttles data speeds in many countries after a daily cap, while eSIM plans provide full-speed data for the entire allotment.
Which messaging apps work best with an eSIM in Reunion?
WhatsApp, iMessage, Telegram, and all major messaging apps work normally on eSIM data in Reunion. Voice and video calls through WhatsApp and FaceTime also work without restrictions. A 5 GB plan supports roughly 50 hours of WhatsApp voice calls or 10 hours of video calls.

Should I download offline maps before visiting Reunion?
Yes. Download Google Maps or Maps.me offline maps for Reunion before your trip. WiFi coverage in Reunion is inconsistent outside major cities. Offline maps provide reliable navigation without depending on connectivity. A 5 GB eSIM at $3.67 covers 7 days of connected use, but offline maps reduce data consumption by 50 to 70 percent for navigation-heavy trips. Download maps over WiFi at home, then use your eSIM data for messaging and real-time updates.
Will my phone's eSIM work with Reunion's carrier networks?
Most eSIM-capable phones released after 2018 support the frequency bands used in Reunion. iPhone XS and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later all work. Your phone must be carrier-unlocked to use a third-party travel eSIM. If your phone was purchased on a carrier installment plan, contact your home carrier to confirm it is unlocked for international eSIM use. eSIM and physical SIM connect to the same carrier towers in Reunion, so band compatibility is identical for both formats.
