FAQ

Before You Buy

What is an eSIM?

An eSIM is a digital SIM built into your phone. Instead of putting a plastic SIM card inside the device, you scan a QR code and install a mobile data plan directly on your phone.

Do I need to remove my normal SIM card?

No. Keep your regular SIM in the phone. Fesim can be used as a second line for mobile data, while your main number can still receive calls and texts if your carrier allows it.

Will Fesim work on my phone?

Your phone needs to support eSIM and must be carrier-unlocked. iPhone XS and newer usually support eSIM. Many Google Pixel and Samsung Galaxy models also support it. Some region-specific phones may not.

Can I use Fesim for calls and SMS?

Most travel eSIM packages are data-only. You can still use WhatsApp, FaceTime, iMessage, Telegram, maps, email, rideshare apps, and browser-based services through mobile data.

Should I buy a country plan, Europe plan, or Global plan?

Choose a country plan if you will stay mostly in one destination. Choose Europe if your trip crosses several European countries. Choose Global if you need broader international coverage.

FAQ

Buying and Payment

How fast do I receive my eSIM?

Usually right away. After payment, the QR code appears on the install step and is emailed to you. If the email is missing, check spam, promotions, and make sure you typed the address correctly.

Can I buy before I travel?

Yes. In most cases, it is best to buy and install before you fly, then activate mobile data when you arrive. Do not start using the plan too early if the validity period begins on first connection.

What payment methods do you support?

The checkout design supports card payments and can be wired to Apple Pay, Google Pay, PayPal, or Stripe depending on the final payment provider configuration.

Can I change my destination after buying?

If the eSIM has not been installed or activated yet, contact support as soon as possible. Once an eSIM is issued or used, changes may be limited by provider rules.

Do prices include taxes?

Plan cards show the final plan price where possible. Payment processing fees, taxes, or local charges should be shown clearly before checkout is completed.

FAQ

Installation

How do I install the eSIM on iPhone?

Go to Settings, Cellular or Mobile Data, Add eSIM, then Use QR Code. Scan the Fesim QR and follow the prompts. Label the line as Fesim or your destination name.

How do I install the eSIM on Android?

Open Settings, then Network and Internet or Connections, SIM manager, Add eSIM. Choose scan QR code and scan the Fesim code. The exact wording depends on the phone brand.

What if I only have one phone and the QR is on that phone?

Open the manual installation details if available, or display the QR on another screen such as a laptop or tablet. You can also email it to yourself and open it on another device.

Can I scan the same QR code twice?

Usually no. Many eSIM QR codes can only be installed once. Do not delete the eSIM from your phone unless support tells you it is safe.

What should I name the eSIM line?

Use a simple label like Fesim, Spain Trip, Europe Data, or Travel Data. This makes it easier to choose the correct line in your phone settings.

FAQ

Activation and Data

When does my plan start?

Most travel eSIM plans start when they first connect to a supported network in the destination, but some start after installation. Always check the plan details before installing.

Why is my eSIM installed but not connecting?

Check that the Fesim line is turned on, mobile data is set to the Fesim line, data roaming is enabled for Fesim, airplane mode is off, and you are in a supported destination.

Do I need data roaming on?

Yes, usually. Travel eSIMs often connect through roaming partner networks, so data roaming must be enabled on the Fesim line. This does not mean your home SIM has to roam.

Can I use hotspot or tethering?

Most plans allow hotspot, but some provider networks can restrict it. If hotspot is important for work or a laptop, check the plan details before buying.

What happens when my data runs out?

Your data may slow down or stop depending on the plan. You can buy another plan or top up if the provider supports top-ups for that destination.

FAQ

Troubleshooting

I scanned the QR but nothing happened. What now?

Make sure your phone supports eSIM, the camera can read the full QR code, and the code has not already been used. Try installing from phone settings instead of the camera app.

My phone says the code is invalid.

The QR may already be used, expired, or not fully visible. Do not keep retrying too many times. Contact support with your order email and destination.

The eSIM connected but internet is slow.

Try toggling airplane mode, choosing another supported network manually, moving away from crowded areas, or restarting the phone. Speeds depend on local coverage and congestion.

I deleted my eSIM by accident.

Contact support immediately. Many eSIMs cannot be restored with the same QR after deletion, but support can check whether a replacement is possible.

I entered the wrong email address.

Contact support with your order details, approximate purchase time, destination, and the correct email address. If the order can be verified, support can resend the QR.

FAQ

Refunds and Safety

Can I get a refund?

Refunds depend on whether the eSIM has been issued, installed, activated, or used. Unused orders are easier to review. Contact support with your order number and reason.

Is it safe to buy an eSIM online?

Yes, if payment is processed through a secure provider and the QR code is delivered privately. Never share your QR code publicly because it can install your plan on another device.

Can someone else use my QR code?

If they scan it first, yes, they may consume the one-time installation. Keep your QR private and only open it on trusted devices.

Will Fesim replace my home phone number?

No. Fesim is meant for travel data. Your phone number stays with your regular carrier unless you manually change call or message settings.

What should I send support when asking for help?

Send your order email, destination, phone model, screenshot of the error, whether the eSIM is installed, and what country you are currently in. This helps support solve it faster.

Still stuck?

Talk to a human before the gate closes.

Send your order email, phone model, destination, and a screenshot of the problem. The more detail you send, the faster we can help.
