⭐ Frequently Asked Questions (FAQ)

Everything you need to know before using an eSIM.

1. What is an eSIM?

An eSIM is a digital SIM that lets you activate a mobile data plan without inserting a physical SIM card. You simply scan a QR code, download the profile, and start using data instantly.

2. Is my phone compatible with eSIM?

Most modern smartphones support eSIM, including:

iPhone XR and newer
Samsung Galaxy S20 and newer
Google Pixel 3 and newer

You can check your device settings:

Settings → Mobile/Cellular → Add eSIM / Add Mobile Plan.

If this option appears, your device supports eSIM.

3. How do I activate the eSIM?

It only takes a few steps:

Purchase your plan
Scan the QR code we send
Enable data roaming

Your eSIM activates immediately depending on the plan type.

4. When should I activate my eSIM?

We recommend activating when you arrive at your destination, unless your plan states “immediate activation.”

Your QR code will not expire unless stated otherwise.

5. Do I need to remove my physical SIM?

No. You can keep your physical SIM for calls/SMS and use the eSIM only for data.

Both can work at the same time.

6. Does the eSIM include calls or SMS?

Most global eSIM plans are data-only.

You can use WhatsApp, iMessage, Zalo, Viber, Telegram, or Messenger for calling and texting over data.

7. Can I use hotspot/tethering with the eSIM?

Yes. Hotspot is supported on almost all plans, unless otherwise stated in the product description.

8. Can I reuse or transfer the eSIM to another phone?

No. Once an eSIM QR code is scanned and installed on a device, it cannot be transferred to another device.

9. What happens if the QR code doesn’t work?

This rarely happens, but if it does:

Check your internet connection
Ensure correct region and plan
Restart your phone

If the issue remains, contact our support team and we will assist immediately.

10. Can I get a refund if my eSIM doesn’t work?

Yes. If your eSIM cannot be activated and our team confirms the issue, you may request a refund.

Please contact support with screenshots of the error.

11. Do I need to turn on data roaming?

Yes. For the eSIM to connect to the network abroad, data roaming must be turned on.

No extra charges apply — the data comes from your purchased plan.

12. Will the eSIM affect my WhatsApp or social media accounts?

No. Your apps remain the same.

Your WhatsApp number still uses your physical SIM number.

13. How long does the eSIM last?

Your plan duration begins when the eSIM first connects to a supported network.

For example: 7-day plan → counts from the first time it goes online.

14. What if my data runs out during the trip?

You can:

Buy another plan
Or purchase a top-up (if available for your country)

15. Can I install the eSIM before traveling?

Yes, but do not activate the plan by turning on data roaming until you arrive.

Your plan begins only after activation.

16. Will I get the best speed (4G/5G)?

Yes. eSIMCyber connects to the leading local carriers in each country for the best available speed.

Coverage may vary depending on local infrastructure.

17. Does the eSIM work in multiple countries?

Yes, if you choose a regional or global plan (e.g., Europe, Asia, Global).

Single-country plans only work in that specific location.

18. How fast will I receive my eSIM after purchase?

Instantly.

Your QR code and installation instructions are sent to your email within seconds.

19. Do I need a passport or ID to buy an eSIM?

No. eSIMCyber does not require identification for purchase.
