Frequently Asked Questions

Got 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.
02

How do I know if my device is eSIM-compatible?
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!
03

Do I need to install an app to use Flash eSIM?
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.
04

What destinations do you cover? Can I buy a plan for multiple countries?
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.
05

What’s the difference between Fixed and Unlimited data plans?
  • 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 1GB each day, then speeds adjust to 2Mbps (still enough for maps/messaging). Speeds reset daily, so you’re always connected.
06

How long does it take to activate my eSIM after purchase?
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.
07

Can I use my regular phone number while using Flash eSIM?
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.
08

What if I have issues with connectivity or setup?
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!
