General Questions

What is an eSIM?

An eSIM (embedded SIM) is a digital SIM card built into your device. Instead of inserting a physical SIM card, you scan a QR code to download and activate a mobile data plan directly onto your device. No physical card, no swapping — just instant connectivity.

What is eSIMBox?

eSIMBox is a digital eSIM provider offering affordable mobile data plans for travelers and international users. We provide eSIM plans for destinations across Asia, Europe, the Americas, the Middle East, and beyond — all delivered instantly to your email.

Do I need a physical SIM card?

No. eSIMBox plans are 100% digital. You receive a QR code via email and scan it to install your eSIM. No physical SIM card is required or shipped.

Can I use eSIMBox for voice calls and SMS?

Most eSIMBox plans are data-only. You can still make calls and send messages using internet-based apps such as WhatsApp, Telegram, FaceTime, Zoom, and Google Meet. For traditional voice calls and SMS, keep your home SIM active alongside your eSIMBox eSIM.

Device Compatibility

How do I know if my device supports eSIM?

On iPhone, go to Settings > General > About and look for an EID number. On Android, go to Settings > About Phone or Settings > Network & Internet > SIMs and look for an "Add eSIM" option. For a full list of compatible devices, visit our Device Compatibility page.

My device supports eSIM but it’s locked to my carrier. Can I still use eSIMBox?

No. Your device must be carrier-unlocked to use an eSIMBox plan. Please contact your carrier to request an unlock before purchasing. Most carriers will unlock your device for free if your contract has ended.

Can I use eSIMBox on my iPad or smartwatch?

Yes, eSIMBox plans are compatible with eSIM-enabled iPads. For Apple Watch, eSIM connectivity is managed through your paired iPhone. Please check our Device Compatibility page for the full list of supported devices.

Purchasing & Payment

How do I purchase an eSIM from eSIMBox?

Simply browse our eSIM plans on www.esimbox.website, select the plan that suits your destination and data needs, add it to your cart, and complete checkout. Your eSIM QR code will be delivered to your email within minutes.

What payment methods do you accept?

We accept major credit and debit cards (Visa, Mastercard, American Express), PayPal, and other payment methods displayed at checkout. All transactions are processed securely.

Are prices in USD?

Yes, all prices on eSIMBox are displayed in USD (United States Dollars). Your bank or payment provider may apply a currency conversion fee if your account is in a different currency.

Is it safe to pay on eSIMBox?

Yes. Our website uses SSL encryption and all payments are processed through secure, PCI-compliant payment gateways. We do not store your full card details.

Delivery & Activation

How will I receive my eSIM?

Your eSIM QR code will be sent to the email address you provided at checkout, typically within 15 minutes of payment confirmation. In rare cases, delivery may take up to 24 hours.

I didn’t receive my eSIM email. What should I do?

Please check your spam or junk folder first. Search for emails from "eSIMBox" or "DaisyeVejar9193@hotmail.com". If you still can’t find it after 24 hours, contact our support team and we will resend your eSIM.

When should I activate my eSIM?

You can install your eSIM at any time, but we recommend activating it when you arrive at your destination to make the most of your data validity period. Most plans start counting from the date of first activation.

Can I install the eSIM on multiple devices?

No. Each QR code can only be scanned and installed once on a single device. Once installed, do not delete the eSIM profile from your device, as it cannot be reinstalled using the same QR code.

I accidentally deleted my eSIM. What should I do?

Please contact our support team immediately at DaisyeVejar9193@hotmail.com or call +84 348 543 400. We will do our best to assist you, though reissuance depends on the policy of the underlying network operator.

How do I install my eSIM?

Data & Coverage

How do I check my remaining data?

Go to your device’s Settings > Mobile Data (or Cellular) and select your eSIMBox eSIM to view data usage. You can also check through the network operator’s app if available in your destination country.

What happens when I run out of data?

Your data connection will stop once your allowance is used up. You can purchase a new eSIM plan from www.esimbox.website. Contact our support team to ask about top-up options for your current plan.

What happens when my plan expires?

Once your plan’s validity period ends, your data connection will stop. Unused data is not carried over or refunded. You can purchase a new plan if needed.

Will my eSIM work in multiple countries?

It depends on the plan you purchase. Some plans cover a single country, while others cover multiple countries or entire regions (e.g., eSIM Asia Pacific, eSIM Europe). Check the coverage details on each plan’s product page before purchasing.

Why is my data speed slow?

Data speeds depend on local network conditions, congestion, and the network operator in your destination country. Some plans may also apply speed throttling after a certain data threshold under fair use policies. This is outside eSIMBox’s direct control.

Refunds & Support

Can I get a refund if I change my mind?

Due to the digital nature of eSIM products, refunds are generally not available once the QR code has been delivered. However, we do accept refund requests under specific eligible circumstances. Please review our Refund Policy for full details.

My eSIM is not working. What should I do?

First, visit our eSIM Setup Guide and check the troubleshooting section. Common fixes include enabling data roaming, toggling airplane mode, or manually selecting a network. If the issue persists, contact our support team and we will assist you.
