What Should You Consider Before Buying an eSIM?

Before purchasing an eSIM, make sure your phone or tablet supports eSIM technology. Not all devices are compatible, so it is worth checking your device specifications or the list of supported models on the manufacturer's website. If your device was purchased through a mobile carrier, you should also verify that it is not SIM-locked.

Before choosing an eSIM plan, check:

✔ Does your tablet support eSIM?

✔ How much data is included in the package?

✔ How long is the package valid?

✔ Can you purchase additional data (top-up)?

✔ Does the plan cover the country you are traveling to?

✔ Are multiple mobile network operators available?

✔ Is hotspot/tethering supported?

✔ Is the installation completed online?

✔ Is technical support available?

✔ Does the validity period begin only after activation in the destination country?

Is an eSIM for a Tablet Really Worth It?

In most cases – absolutely.

The biggest advantages include:

• lower costs than traditional roaming outside the EU,
• quick activation without visiting a mobile carrier's store,
• no need to purchase a local SIM card,
• the ability to work immediately after arrival,
• predictable internet costs,
• convenient management of data packages,
• greater security than using public Wi-Fi networks.

For businesses, this also means saving employees' time and making business travel expenses easier to manage.

eSIM for Business Travel – Best Practices

To avoid problems during your trip:

• install your eSIM profile before traveling,
• verify that your tablet supports eSIM,
• download essential work documents for offline access,
• make sure Data Roaming is enabled for the eSIM if required by the provider,
• disable data roaming on your physical SIM card,
• monitor your data usage,
• have a backup plan in case of weak network coverage.

What Are the Limitations of eSIM Technology?

Although eSIM is an extremely convenient solution for travelers, it is worth being aware of its limitations. In most cases, these are not significant, but it is useful to know them before purchasing a package.

• Not all devices support eSIM – Before purchasing, check whether your smartphone, tablet, or smartwatch is compatible with eSIM technology. If your device was purchased through a mobile carrier, make sure it is not SIM-locked.
• An internet connection is required for installation – Activating an eSIM profile requires a stable internet connection, so it is recommended to install it before departure using a trusted Wi-Fi network.
• The eSIM profile is generally for one-time installation – Most providers allow the profile to be installed only once. If you remove the eSIM from your device, reinstalling it using the same QR code is usually not possible. Therefore, you should not delete the profile before you have finished using your data package.
• Most travel eSIM packages are data-only – Standard travel eSIM plans typically do not include a local phone number or traditional voice calls and SMS services. However, this is rarely a major limitation because you can communicate using internet-based apps such as WhatsApp, Messenger, FaceTime, Microsoft Teams, or Zoom.

How to Check If Your Device Supports eSIM – Step by Step

Before purchasing an eSIM package, it is worth confirming that your phone or tablet supports eSIM technology. The verification process takes only a few minutes.

1. Check your device model – Go to Settings → About Phone/Tablet and verify the exact model name.
2. Review the manufacturer's specifications – Visit the manufacturer's website or check the list of supported devices provided by your chosen eSIM provider.
3. Check your EID number – Dial *#06# on your phone. If an EID number appears in addition to the IMEI number, your device supports eSIM technology.
4. Make sure your device is not SIM-locked – Some carrier-purchased devices may have restrictions that prevent them from using eSIM profiles from other providers.
5. Look for the eSIM option in your settings – On most devices, you can find it under Settings → Mobile Network / SIM Cards → Add eSIM. If this option is available, your device is ready for eSIM installation.

FAQ – Frequently Asked Questions

Does every tablet support eSIM?

No. eSIM functionality is available only on selected tablet models. Before purchasing an eSIM package, check your device specifications or the manufacturer's information. Many newer Apple, Samsung, and Microsoft tablets support eSIM, but not every version of these models includes this feature. It is also worth confirming that your device is not SIM-locked and supports eSIM profiles.

Can I use an eSIM and a physical SIM card at the same time?

Yes. Many modern devices support Dual SIM, allowing you to use one number for calls while using an eSIM for mobile data. This is especially convenient during business trips because it lets you keep your business or personal number active. You can continue receiving calls and text messages while using your eSIM for mobile internet abroad.

Does eSIM work immediately after arrival?

Yes. If your eSIM profile has been installed correctly before your trip, your device will usually connect to a local mobile network within a few minutes after arriving in the destination country and meeting the activation requirements. For maximum convenience, it is recommended to install your eSIM before departure using a stable Wi-Fi connection. Once you land, simply enable mobile data and start using the internet.

What should I do if I run out of data?

Most providers, including XOXO WiFi, allow you to conveniently purchase an additional data package (top-up) without installing a new eSIM profile. The entire process can be completed online in just a few minutes without visiting a carrier's store. This enables you to quickly restore internet access and continue working or traveling without unnecessary interruptions.

When does the package validity period begin?

With XOXO WiFi, the validity period starts when your eSIM is activated in the destination country or region covered by your package—not at the time of purchase. This allows you to buy and install your eSIM before departure without losing any days of validity. It is a convenient solution that makes trip planning easier and eliminates unnecessary stress before your journey.

Is eSIM safer than public Wi-Fi?

Yes. Using your own mobile internet significantly reduces the risks associated with open public Wi-Fi networks and provides greater control over your internet connection when working with business data. This is especially important when accessing corporate systems, online banking, or confidential documents. Avoiding unsecured hotspots also helps improve data protection while traveling.
