eSIM FAQ: Everything You Need to Know

An eSIM (embedded SIM) is a digital SIM built into your device that allows you to activate mobile data without inserting a physical SIM card.

👉 Learn more about what an eSIM is

A physical SIM must be inserted and replaced manually, while an eSIM is installed digitally and managed directly from your device settings. This makes switching plans faster and easier, especially when traveling.

Yes. Most modern smartphones and many tablets support eSIM, including newer iPhone, Samsung Galaxy, and Google Pixel models.

👉 Check if your device supports eSIM

Yes. eSIM uses the same security standards as physical SIM cards and connects directly to trusted mobile networks. There is no additional risk compared to traditional SIM usage.

Not completely. Many devices support both physical SIM and eSIM, allowing dual SIM usage. This lets you keep your main number while using eSIM for data.

Yes. Travel eSIMs are designed for international use and work in over 200 countries and regions worldwide.

👉 Browse available eSIM destinations

Most travel eSIM plans are data-only. You can still make calls and send messages using apps such as WhatsApp, FaceTime, Telegram, or LINE.

Travel eSIMs are ideal for tourists, business travelers, digital nomads, and anyone who needs fast and reliable mobile data abroad.

In most cases, yes. Travel eSIMs usually offer lower costs and clearer pricing than traditional roaming plans, with no long-term contracts.

A travel eSIM works by downloading a digital SIM profile to your device. Once installed, it connects to supported local networks at your destination, allowing you to use mobile data without a physical SIM.

👉 Read the full travel eSIM workflow

The eSIM starts working automatically when it first connects to a supported local network at your destination. No manual activation is usually required.

The validity period starts from the first network connection, not from the installation time. Installing the eSIM in advance will not reduce your plan duration.

👉 See the installation guide

Yes. You can install your eSIM before traveling while connected to Wi-Fi. The plan activates only when you arrive and connect to a local network.

In most cases, yes. Once mobile data is enabled, the eSIM connects within seconds after landing, depending on local network availability.

Yes. Most eSIM-compatible devices support dual SIM functionality, allowing you to use your physical SIM for calls and eSIM for data.

You can temporarily disable the eSIM in your device settings. However, once activated, the plan validity continues to run.

When your plan expires, the eSIM stops providing internet access. You can remove it and purchase a new eSIM plan if needed.

👉 Choose a new eSIM plan

You can install an eSIM by scanning a QR code or manually entering the activation details in your device settings. The process is fully digital and does not require a physical SIM card.

Yes. A stable Wi-Fi connection is required to download and install the eSIM profile. Once installation is complete, Wi-Fi is no longer needed for activation at your destination.

No. Each eSIM QR code can usually be installed only once on a single device. If the eSIM is deleted after installation, it cannot be reinstalled again.

If an installed eSIM is deleted, it usually cannot be recovered or reinstalled. We recommend contacting customer support immediately if this happens.

In most cases, no. eSIM QR codes are single-use for security reasons. Once installed or deleted, the same QR code cannot be reused on the same or another device.

The overall process is similar, but menu names and steps may differ slightly. iPhones use Settings → Cellular → Add eSIM, while Android devices typically use Settings → Network & Internet → SIMs.

👉 Check device-specific instructions

eSIM installation usually takes between 1–5 minutes, depending on your internet connection and device model.

👉 Check eSIM compatibility by device

Yes. Some devices sold in specific regions may have different hardware or carrier restrictions that affect eSIM support. Always check your exact model and region before purchasing an eSIM plan.

Travel eSIMs connect to local mobile networks in your destination and typically support 4G LTE speeds. In some locations, faster speeds may be available depending on network coverage and device capability.

Yes, 5G may be supported if all conditions are met: your device supports 5G, the local network offers 5G coverage, and the selected eSIM plan allows it. Availability varies by destination.

In most cases, hotspot and tethering are supported on eSIM plans. However, performance may depend on your device and local network policies.

Data needs vary by usage. Light activities like messaging and maps usually require 1–3GB per week, while social media, navigation, and streaming may require larger data plans.

Yes. eSIM works the same as a regular mobile data connection and is compatible with most VPN services. VPN performance may vary depending on network speed and location.

Some eSIM plans may apply fair usage policies or speed limits depending on the destination and network conditions. Always check plan details before purchasing.

👉 Learn how travel eSIM plans work

First, make sure mobile data is enabled for the eSIM and that you are located within a supported destination. Try restarting your device and toggling airplane mode on and off.

This message may appear if the eSIM has not yet connected to a supported network or if the device needs a restart. In many cases, the eSIM will activate automatically once a compatible network is detected.

“No Service” usually means your device is outside coverage, mobile data is turned off for the eSIM, or the local network signal is temporarily unavailable. Try manually selecting a network in your device settings.

Before contacting support, please check that your device is eSIM-compatible, confirm your destination is covered, restart your phone, and ensure mobile data is enabled for the eSIM.
