Frequently Asked Questions About Réunion eSIMs
What is the best eSIM for Réunion?
SimCorner stands out as the best eSIM for Réunion, balancing top-tier network coverage, flexible data packages, instant email delivery, and seamless QR code activation. Whether you are travelling for work or vacation, our eSIM Réunion plans deliver local 5G/4G speeds with no roaming fees.
Will my Réunion eSIM work while hiking in the Cirque de Mafate?
The SFR Réunion network provides coverage across much of the Cirque de Mafate, though the rugged terrain means signals can be intermittent in deep valleys. Your Réunion eSIM is ideal for checking digital trail maps or sending messages from mountain lodges. For the best results, download your maps for offline use before entering the most remote wilderness areas.
Can I use my Réunion eSIM to navigate with Waze while driving?
Yes, your Réunion eSIM provides high-speed data perfect for Waze or Google Maps. Navigating the Route des 400 Virages to Cilaos requires real-time updates for traffic and weather conditions. Having a dedicated data connection ensures you receive these alerts instantly, helping you navigate the island's winding and often challenging mountain roads safely and efficiently.
Will my eSIM work at Roland Garros Airport upon arrival?
Yes, the SimCorner Réunion eSIM is designed to connect as soon as you land. Once you take your phone out of airplane mode and turn on data roaming for the eSIM profile, it will search for the SFR Réunion network. This allows you to arrange transport or contact your accommodation immediately without searching for airport Wi-Fi or local SIM kiosks.
Can I use my device as a hotspot with the SimCorner Réunion tourist eSIM?
Yes, all our Réunion eSIM plans support full tethering and personal hotspots. Whether you have a fixed 1–50GB pack or an unlimited plan, you can share your high-speed connection with laptops, tablets, or fellow hikers. This is ideal for situations where hotel Wi-Fi is patchy or unavailable, ensuring your entire group has a secure data connection for remote work, streaming movies, or social media.
What happens if I use all my high-speed data on the Réunion unlimited data eSIM?
If you reach your daily high-speed limit on the unlimited plan, your SimCorner Réunion eSIM ensures you never go offline. Your speed will be lowered to 128kbps for the remainder of the 24-hour period before your high-speed allowance is restored automatically. This provides total peace of mind for navigating the remote Cirques or checking restaurant reviews in Saint-Gilles, even after a heavy day of sharing.
Do I need to provide a passport to activate my Réunion eSIM?
No, one of the primary benefits of the SimCorner Réunion eSIM is that it requires no personal documentation or passport scans. Unlike local physical SIM cards purchased in Saint-Denis which often require registration and paperwork, our digital eSIM is prepaid and ready to activate instantly, allowing you to maintain your privacy while staying connected.
How do I ensure my eSIM Réunion is ready for my arrival in Saint-Denis?
We recommend installing your SimCorner Réunion eSIM while still in Australia using a stable Wi-Fi connection. Once the profile is on your device, keep the line turned off and data roaming disabled until your plane touches down at Roland Garros Airport. Upon landing, simply switch your mobile data to the SimCorner eSIM and turn roaming ON to connect instantly to the local high-speed SFR Réunion network.
Can I use Apple Pay or Google Pay in Réunion with my eSIM data?
Yes, contactless payments via Apple Pay and Google Pay are widely accepted throughout Réunion at most supermarkets, restaurants, and retail stores. By using your Réunion eSIM, you ensure a secure and private 4G connection to authorise these transactions instantly. This is far safer than using unencrypted public Wi-Fi, allowing you to pay with just a tap of your phone while keeping your financial data protected.
Can I top up my data if I run out of my Réunion eSIM data allowance?
If you exhaust your fixed 1–50GB data plan, you can purchase a top-up instantly via the SimCorner website without needing to install a new QR code. For Unlimited plans, your high-speed allowance resets automatically every 24 hours. This flexibility ensures that whether you are trekking in Salazie or relaxing by the lagoon, you can maintain peak speeds without having to search for a local retail store.
Does the Réunion eSIM come with a local phone number?
This is a data-only travel eSIM and does not include a local Réunion (+262) phone number for traditional voice calls or SMS. However, you can maintain full voice and text connectivity by using data-based apps like WhatsApp, FaceTime, Viber, and Messenger. This allows you to stay connected with high-speed data without the privacy risks, mandatory passport uploads, or long retail queues associated with local SIM registrations.
When is the best time to install my eSIM Réunion data plan?
We recommend installing your eSIM Réunion before departure or at the airport before boarding. The installation requires a stable internet connection. Completing this step ahead of time ensures that your eSIM is ready to connect instantly upon arrival.
Note: Some eSIMs activate directly upon scanning the QR code. Check ‘Things to Know’ on the product page, or refer to your post-purchase email for your custom setup guide.How do I install and activate my eSIM Réunion?
- iPhone: Go to Settings > Mobile > Add eSIM.
- Android: Go to Settings > Connections > SIM manager > Add eSIM.
Do I need an active internet connection to install my Réunion eSIM?
Yes, a stable Wi-Fi or cellular data connection is mandatory during the initial installation phase. Your device must communicate directly with the network servers to download the digital eSIM profile. Attempting to install the eSIM Réunion without an internet connection will result in a setup failure.
Note: Most SimCorner eSIMs do not need internet for activation. Enabling data roaming triggers the activation.Can I install the Réunion eSIM using a screenshot or image from my gallery?
Yes, with most modern iOS and Android devices, you can upload a screenshot or image directly through the Add eSIM menu. If your specific device does not support gallery uploads, you can display the Réunion eSIM QR code on a laptop, tablet, printout, or secondary screen and scan it using your phone's camera.
When does the validity countdown start, and how are days calculated?
The validity period does not begin upon purchase or installation. The countdown starts only when your eSIM Réunion gets activated by connecting to a supported local network. From the activation time, your plan days are calculated based on continuous 24-hour cycles.
Does the Réunion eSIM expire if left unactivated?
No, our Réunion eSIM does not expire or get auto-activated, unlike many other eSIM providers who enforce 15–30-day activation periods. You can safely purchase your eSIM data plan months in advance during a sale or while planning your itinerary. Your eSIM Réunion remains dormant and ready for use whenever your trip begins.
Can I transfer my active eSIM Réunion profile to another phone?
No, travel eSIMs are single-use digital profiles that lock to the physical hardware of the initial device. Once a QR code has been scanned, it cannot be transferred to a different handset. Additionally, if you delete the profile from your settings, it cannot be re-scanned or reused.
How do I track my data balance and purchase top-ups?
You can use the SimCorner App for live data tracking and instant on-the-go recharges.
If you prefer not to use the app, you can also monitor your usage directly through your device's native cellular settings. Please note that top-up availability varies by product, so be sure to check your specific product details before purchasing to confirm if your chosen plan is eligible for recharges.How do I check if my device is eSIM compatible?
iOS:
Go to Settings > General > About
Scroll down to Available SIM (or Digital SIM).
If an IMEI or EID number is listed, your iPhone supports eSIM.
Android:
Dial *#06#on your keypad.
If an EID (Embedded Identity Document) number appears on your screen, your device supports eSIM.
How do I check if my device is carrier-unlocked?
iOS: Navigate to Settings > General > About and find Network Provider Lock. If it says No SIM restrictions, your device is unlocked.
Android: The most accurate test is to temporarily insert a physical SIM card or install an eSIM from a different mobile network. If your phone connects to the network and you can make a call or use data, your device is unlocked.Can I use Réunion eSIM if my phone is currently locked to a network carrier?
No, you cannot use an eSIM Réunion if your phone is locked to your home provider. Carrier-locked phones automatically reject any third-party travel eSIM profiles. You must contact your current carrier to fully unlock your device before attempting to install or activate our Réunion travel eSIM.
Why are iPhones from Mainland China, Hong Kong, or Macau incompatible?
Apple manufactures iPhones for the Chinese, Hong Kong, and Macau markets without an internal eSIM chip. To comply with local regulatory demands and consumer preferences, Apple replaced the eSIM hardware entirely with a dual-sided physical tray for nano-SIMs.
Got an iPhone from one of these regions? Explore our physical Réunion SIM card options.
How many eSIM profiles can I store and run on my phone at the same time?
Storage: Most modern smartphones allow you to download and store between 5 and 10 distinct eSIM profiles directly on their internal chip.
Usage: While you can store many, you can generally only run one or two profiles actively alongside your primary home SIM card at any given time, depending on your device generation.
Will this eSIM work on a jailbroken (iOS) or rooted (Android) device?
Yes, but we cannot guarantee optimal network performance because jailbreaking or rooting modifies core security protocols. Security flags within cellular operating systems can occasionally interfere with the profile registration process or prevent automatic network connections.
Can I keep my home SIM in my phone alongside the eSIM Réunion?
Yes, modern smartphones feature Dual SIM technology, allowing your physical home SIM and your digital eSIM Réunion to run simultaneously. You simply assign data usage to your SimCorner profile while keeping your home line active for incoming OTPs.
Note: Receiving incoming calls will trigger roaming charges from your home provider.Can I keep my original WhatsApp and iMessage accounts?
Yes, these services are linked to your home phone number or account rather than the SIM card. When you insert your eSIM Réunion, your apps may prompt you to update your number—always select Keep Existing Number. This ensures your account, chat history, and contacts remain tied to your home number, allowing you to message and call as usual throughout your trip.
Does my Réunion unlimited data eSIM have a hidden Fair Usage Policy (FUP) throttle?
No, we believe in complete transparency. Unlike other providers who hide their speed drops in fine print, our limits are fully disclosed up front. Your eSIM Réunion unlimited plan includes:
- High-Speed Data: 3GB of 4G/5G data per day.
- Speed After 3GB: If you exceed 3GB in a day, your speed drops to 128kbps.
- Reset Time: Every 24 hours from the exact time of your initial activation.
Can I still receive bank SMS codes (2FA) while using eSIM Réunion?
To receive bank verification SMS codes (2FA) using our eSIM for Réunion, your device must support Dual SIM functionality so your home SIM remains active alongside your travel plan.
Pro-Tip: If your phone only runs one active SIM at a time, your home line will become temporarily inactive. To prevent losing account access, we highly recommend setting up email-based 2FA or an authenticator app before you depart.My trip was canceled; can I get a refund if I haven't used the eSIM?
Yes, you can get a refund. Please reach out to our 24/7 customer support as soon as possible.
If your travel plans change or your trip is canceled, SimCorner offers a flexible refund policy for unused profiles. As long as your eSIM Réunion has not been installed or activated on a device, you are eligible for a return and refund.What are the SimCorner 5% price beat and 30-day price lock guarantees?
5% Price Beat: If you find an identical, cheaper travel plan from another provider, even on sale, we will beat their listed price by 5%.
30-Day Price Lock: If our own price falls within 30 days of your purchase, we will credit you the difference.
