Can I still use my regular SIM card with an eSIM?

Yes. Most eSIM-compatible phones are dual-SIM, meaning you can use your physical SIM for calls and texts from home while using the eSIM for mobile data abroad.

I accidentally deleted my eSIM - can I reinstall it?

Contact our support team with your order number. We can usually provide a new activation link or QR code. Note that some eSIMs can only be installed once, so a new plan may be required.

Do I need to unlock my phone to use an eSIM?

Your phone must be carrier-unlocked to use a third-party eSIM. If you bought your phone outright or finished your contract, it's usually unlocked. Contact your carrier if unsure.

Can I extend my eSIM or add more data?

Many of our plans support eSIM-Global.VIP Top-Up. We'll notify you at 20% and 10% remaining data with a direct link to purchase more. Your new data is added to your existing eSIM immediately - no need to reinstall anything.

Is an eSIM safe and secure?

Yes. eSIMs use the same encryption and security standards as physical SIMs. They cannot be physically stolen or cloned, and are tied to your specific device.

What if the activation link doesn't work?

Use the QR code provided on the confirmation page or in your email as a backup. If scanning isn't possible, you can manually enter the activation code and SM-DP+ address under "Enter Details Manually" in your eSIM settings.
