Frequently Asked Questions

Welcome to our FAQ section, where we address the most common queries about eSIM technology, especially for those planning to travel to Europe. Our aim is to provide clear, concise, and helpful answers to ensure you're well-prepared for seamless connectivity abroad.

What is an eSIM and how does it differ from a physical SIM?

An eSIM, or embedded SIM, is a digital SIM card that allows you to activate a cellular plan from a network provider without needing a physical SIM card. Unlike traditional physical SIMs that you insert into your phone, an eSIM is built directly into your device's hardware. This means you can store multiple eSIM profiles on a single device and switch between them digitally, offering greater flexibility and convenience, especially for travellers.

Which devices support eSIM?

Many modern smartphones, tablets, and smartwatches now support eSIM technology. Generally, devices released in recent years from manufacturers such as Apple (iPhone XR and newer), Samsung (Galaxy S20 and newer, certain Fold and Flip models), Google (Pixel 3 and newer), and some other brands are eSIM compatible. It is always advisable to check your specific device model's specifications or consult the manufacturer's website to confirm eSIM support before purchasing a plan.

Can I use an eSIM alongside my regular SIM card?

Yes, absolutely! Most eSIM-compatible devices support dual SIM functionality, which means you can use your physical SIM card (for your home number) and an eSIM (for your travel data) simultaneously. This is incredibly convenient for travellers, as it allows you to maintain your primary number for calls and texts while using the eSIM for affordable local data in your destination country. You can easily manage which SIM is active for data, calls, or messages through your device settings.

How do I know if an eSIM will work in my destination country?

eSIM providers typically specify the countries and regions where their plans are valid. When browsing for an eSIM plan, carefully review the coverage details provided by the vendor. For European travel, many providers offer regional eSIMs that cover multiple countries, ensuring seamless connectivity across borders within the continent. Always confirm that your specific destination is included in the plan's coverage list before purchasing.

What happens if I run out of data on my travel eSIM?

If you deplete your data allowance on a travel eSIM, your internet connectivity will typically cease or slow down significantly, depending on the provider's fair usage policy. Most eSIM providers offer top-up options, allowing you to purchase additional data packages directly through their app or website. It's often a good practice to monitor your data usage and consider topping up before you completely run out, especially if you rely heavily on internet access for navigation or communication.

Can I reuse an eSIM for future trips?

Whether an eSIM can be reused depends entirely on the specific plan and provider. Many travel eSIMs are designed for a single trip and expire after a set duration or when the data allowance is used up, at which point the profile might become inactive. Some providers, however, offer "rechargeable" eSIMs where you can add new data packages for subsequent trips. Always check the terms and conditions of your eSIM plan regarding its validity and reusability.

Is an eSIM more cost-effective than international roaming?

For most international travellers, particularly those venturing into Europe, an eSIM is generally a more cost-effective solution compared to traditional international roaming from your home provider. Roaming charges can accumulate rapidly and often have high per-megabyte rates. Travel eSIMs, on the other hand, offer local data rates, which are significantly lower, providing better value for money and predictable costs without bill shock.

How do I activate an eSIM?

Activating an eSIM typically involves scanning a QR code provided by your eSIM vendor, often found in an email or on their website after purchase. Once scanned with your device's camera (usually through Settings > Mobile Data/Cellular > Add eSIM), your phone will prompt you through the installation process. It's crucial to have a stable internet connection (Wi-Fi is ideal) during the installation to download the eSIM profile onto your device.

What should I do if my eSIM isn't connecting?

If your eSIM isn't connecting, first ensure that you have enabled the eSIM profile in your device settings and selected it for mobile data. Check that data roaming is turned on for the eSIM profile if required by the provider. Sometimes, a simple restart of your device can resolve connectivity issues. If problems persist, verify your APN settings against the provider's instructions and contact their customer support for assistance, providing details of your device and location.

Are there eSIM options for multi-country European trips?

Yes, absolutely. Many eSIM providers specialise in regional plans that cover a wide range of European countries under a single package. These "Europe-wide" or "EU roaming" eSIMs are ideal for travellers planning to visit multiple countries within the continent, as they eliminate the need to purchase a new SIM or eSIM for each destination. This offers seamless connectivity as you cross borders, without the hassle of changing profiles.

Do I need Wi-Fi to install an eSIM?

Yes, you will generally need a stable internet connection, typically Wi-Fi, to install an eSIM profile onto your device. The installation process involves downloading the eSIM's digital profile from the network provider's servers. Once the profile is successfully downloaded and activated, you will no longer need Wi-Fi to use the eSIM's mobile data services, assuming you have coverage in your location.

Can I get a refund on an eSIM plan?

Refund policies for eSIM plans vary significantly between providers. Generally, refunds are often possible if the eSIM could not be installed due to a technical issue on the provider's end, or if the plan was purchased in error and not yet activated. However, if the plan has been activated, used, or if the issue is due to device incompatibility or user error, a refund may be more difficult to obtain. Always review the specific refund policy of the eSIM provider before making a purchase.

Key eSIM Terminology Explained

eSIM (Embedded Subscriber Identity Module)
A digital SIM embedded directly into a device, eliminating the need for a physical card. It allows users to activate a cellular plan without inserting a physical SIM.
Dual SIM
The capability of a device to use two different SIM cards or eSIM profiles simultaneously. This is often implemented as "Dual SIM Dual Standby" (DSDS), meaning both SIMs are active but only one can be used for data/calls at a given moment.
Data Roaming
The ability to use your mobile phone services (calls, texts, data) when travelling outside the geographical coverage area of your home network, by connecting to a partner network in the foreign country. eSIMs often provide a more affordable alternative to traditional data roaming charges.
APN (Access Point Name)
A gateway between a mobile network (GPRS, 3G, 4G, 5G) and another computer network, usually the public internet. Sometimes, for an eSIM to work correctly, you may need to manually configure the APN settings in your device.
QR Code Activation
The most common method for installing an eSIM profile. A user scans a unique QR code provided by the eSIM vendor, which contains all the necessary information to download and activate the eSIM profile on their device.
Top-Up
The process of adding more data, calls, or texts to an existing mobile plan or eSIM profile. This is useful when you have consumed your initial allowance and wish to continue using the service without purchasing a new plan.
