Frequently Asked Questions

We’ve Got Answers

01 What is an eSIM, and why should I choose Flash eSIM over other providers?

An eSIM is a digital SIM embedded in your device, allowing you to activate a cellular plan without a physical SIM card. Flash eSim stands out by offering both limited and unlimited data options—perfect for travelers who want flexibility. No app required: Manage everything directly through your Whatsapp or our website.

Most devices released after 2018 support eSIMs. This includes iPhones (XS/XR or newer), Google Pixels (3+), Samsung Galaxy (S20+ or newer), and select iPads. Check our eSIM Compatibility List for exact models. Unsure? Contact us with your device details!

No! Unlike some providers, Flash eSIM works entirely through your device’s settings and our website. After purchasing a plan, you’ll receive a QR code and setup instructions via email—just scan and go.

We specialize in regional and single-country plans (e.g., “Europe 15 Countries” or “France Only”). This lets us offer better network reliability and value compared to generic global plans. Browse Our eSIM Plans to see all available regions and countries.

  • Fixed eSIM plans: : A set amount of data (e.g., 3GB, 5GB) delivered at full 4G/5G speeds for your entire trip—no slowdowns, ever. Track your data in real-time via your device settings.
  • Unlimited eSIM plans: Never run out of data! Full-speed for the first 2GB each day, then speeds adjust to 2Mbps (still enough for maps/messaging). Speeds reset daily, so you’re always connected.

Instantly! You’ll receive your QR code/Direct installation link and instructions via email and Whatsapp immediately after payment. Activate it before your trip or mid-travel—no expiration. The validity of your eSIM doesn’t start counting until you start using the data in the destination country.

Yes! Your original number stays active for calls/texts and on WhatsApp, iMessage, Telegram, etc. Use Flash eSIM for data while keeping calls/texts on your primary SIM.

Our 24/7 support team specializes in eSIM troubleshooting. Visit our Help Center for guides, or Contact us. Most issues (e.g., APN settings) are resolved in minutes!

eSIM Compatible Devices

To use an eSIM, your device must be both carrier-unlocked and compatible with eSIM technology. Check our comprehensive list below to confirm if your smartphone supports eSIM. If you can’t find your device on the list, it likely isn’t eSIM-enabled. However, to verify manually, open Settings → Connections → SIM Card Manager. If you see the option to “Add mobile plan,” your phone is ready for eSIM.
