Frequently Asked Questions

Can I install the eSIM before my trip?

Yes! We recommend installing the eSIM before you travel. The data validity only starts when you activate it in the destination country.

Can I use my regular SIM and eSIM at the same time?

Yes. Most modern smartphones support Dual SIM — you can keep your home SIM for calls and texts while using FlashSim for data.

What if my QR code doesn’t scan?

Try increasing the brightness of the screen displaying the QR code, or manually enter the activation code provided in your email. If issues persist, contact our support team.

Can I reuse the QR code?

No. Each QR code is valid for a single activation only. Once scanned, it cannot be used again.
