eSIM with Unlimited Data in United Kingdom

The UK eSIM is optimized for the best coverage and speed within the UK. To travel across other European countries, we recommend our Travel eSIM for Europe, which ensures connectivity across the continent.

Your plan activates immediately upon connecting your eSIM to any supported network. For example, if you bought a 1-day mobile plan and you activate your plan at 10 AM, it remains active for a full 24 hours, concluding at 10 AM the following day.

The UK eSIM only allows you to use mobile data. It does not include a local phone number for mobile calls or messages. You can still make calls using apps like WhatsApp.

You can check if your smartphone is eSIM compatible here.

Once you purchase your eSIM, you will receive a confirmation email with instructions to install it immediately using a QR code or manual code. Remember that once the eSIM is purchased, it cannot be returned.

You don’t need to do anything to keep your WhatsApp number. You’ll automatically keep your number, contacts and conversations.

The Holafly eSIM service offers maximum speed coverage (4GLTE). But bear in mind that in some areas of limited coverage there may be a lower speed connection.

Yes. To ensure that your eSIM gets the best coverage, you must turn on data roaming on your mobile settings. This will not incur any additional charges, as long as you have already set up the Holafly eSIM.

If you cannot find the code, please contact our 24/7 customer support team at help@holafly.com or our online chat function. We will resend the code to your email.

If you use all your data or run out of days, your eSIM card will no longer work and you will lose internet connection.

Whichever is available for your destinations and suits your travel needs better! You can choose plans from 1 to 90 days.

In a rare scenario, yes. Operators enforce an international measure called Fair Usage Policy to ensure fair internet usage and allow all users to enjoy optimal connection. This measure might be applied for a period of no more than one (1) day. It’s beyond Holafly’s control, but don’t worry! If this measure affects you, the restriction will be lifted the next day, and you’ll have your original plan speed back.

Holafly’s eSIMs are compatible with a wide range of iPhone devices, including most models released since the iPhone XS. Check out our full list of eSIM compatible devices,including all iPhone devices, Android devices, Google Pixel devices, Samsung devices, and more.

An eSIM (embedded SIM) is a digital SIM card that can be installed directly into your smartphone or other mobile devices. It is an alternative to the physical, removable SIM card you’re used to.

Yes, you can do so by logging into your customer panel on the Holafly Center. You will find the data plans you can purchase there. Once you’ve made your purchase, it will be activated immediately on the eSIM you have linked.

Certainly! With the Italy eSIM, you have the capability to share up to 500MB of data per day across devices by creating a WiFi connection using your smartphone. Refer to your device instructions for guidance on setting up a WiFi connection via a mobile hotspot.

After your purchase, we will send a QR code and manual instructions to your email. Either print the QR confirmation code or open it on your computer. On your cell phone, go to Settings > Mobile Data > Add Data Plan and scan the QR code. Your phone will allow you to assign a specific name to this data plan. You will now be able to switch between your Holafly data plan and the original plan from your provider. The Holafly data plan will only be operational once you arrive at your destination. Once you land, turn on data roaming on your cell phone settings and activate the Holafly data plan. Consult your phone’s user manual for more details on adding a data plan. All eSIM products come with comprehensive set-up instructions.

Set up your eSIM before your departure. Once you reach your destination, just activate the data plan turning on data roaming. We recommend you print the QR code to take it and manual instructions with you on vacation, just in case. Remember that you need internet access to install the eSIM.

You can manage your eSIMs and access all purchased data plans by logging into your Holafly Center through the Holafly website.

If needed or when changing phones during your trip, you can transfer your eSIM. However, note that you can only transfer the eSIM to two devices—the original and a new phone. Once you’ve installed it on a different device than the original, you won’t be able to reinstall it on the original device and you must deliver the eSIM from the original device to install it in the new device.

Yes! But keep in mind that you don’t need to do so. As soon as your plan expires your eSIM will no longer work.

If you are using a dual SIM phone or an Apple device, you can use your physical SIM card and your eSIM in the same device. Choose the SIM card for phone calls and SMS, and Holafly eSIM for data from your device. Please remember that if you leave your SIM card activated, your mobile data network provider may apply data roaming charges to receive or make phone calls as well as SMS.

At Holafly we are aware that our users may have unforeseen events after making the purchase. Therefore, you can request a refund in the following circumstances:

– You bought the eSIM without checking the compatibility with your cellphone.
– You canceled your trip or you no longer need the eSIM.
– Our eSIMs generally work fine, but if you experience connection issues, we can provide you with a full or partial refund.

Once the refund is approved, you will receive the money on to the same account with which you made the payment. This process can take between 5 to 10 business days.

For more details, terms and conditions, we invite you to read our Refund Policy.

Your eSIM will connect to all the local phone networks that Holafly partners up with. You can review them in the Technical Specs

It is! Of course if you ask us which eSIM UK card is the best, we will naturally answer it’s ours! Why? Because of our unlimited data, the flexibility to select a custom number of days, and many more special features.

Both digital and physical SIM cards connect your device to a mobile network, but they work and provide benefits in very different ways: physical SIM cards, are made of plastic and must be inserted into the device in order to work, while an eSIM, or digital SIM, does not need to be inserted into the phone. Instead, it can be installed by simply scanning a QR code to activate the service. Physical SIM cards can be vulnerable to theft, damage, or loss, while eSIMs don’t face these potential issues.

Yes, it is possible. You can install an Holafly eSIM for the UK before you travel, but you should activate the mobile data plan when you arrive at your destination, so you don’t start using data plan prematurely.
