Frequently Asked Questions

An eSIM (embedded SIM) is a chip permanently soldered into your device. Unlike a physical SIM card, it cannot be removed. Instead, carrier profiles are downloaded digitally via QR code or app. You can store multiple profiles and switch between them without handling any physical hardware. The technology is standardized by the GSMA and supported by all major carriers globally.

Purchase a plan from an eSIM provider. You will receive a QR code by email. On iPhone: Settings → Cellular → Add eSIM → Use QR Code. On Android: Settings → Network → SIM cards → Add eSIM → Scan QR code. Scan the code and follow the prompts. The profile downloads in seconds. Configure the eSIM as your data line in settings.

Yes, and this is one of the key advantages of eSIM. You can purchase and install the profile weeks before departure. Most plans either activate on first use in the destination country or start counting from the activation date — check your provider's terms. Installing in advance means you have connectivity the moment you land.

Ensure you have a stable Wi-Fi connection during activation. The QR code can only be scanned once — if it fails mid-process, contact your provider immediately for a replacement code. Some providers offer manual activation codes (SM-DP+ address and activation code) as an alternative to QR scanning.

Yes, an internet connection is required to download the carrier profile during activation. This can be your home Wi-Fi, airport Wi-Fi, or hotel Wi-Fi. Once activated, the eSIM works independently of Wi-Fi, connecting to the mobile network like any SIM card.

On iPhone: Settings → General → About → look for "Available SIM" or "Digital SIM." On Android: Settings → Network & Internet → SIM cards — if an "Add eSIM" option appears, your device is compatible. You can also check your device manufacturer's website or our device compatibility guide.

Yes. Carrier-locked devices may only accept eSIM profiles from the locking carrier. Contact your home carrier to request an unlock — most carriers unlock devices after the contract period ends or upon request. Devices purchased outright (not subsidized) are typically unlocked by default.

Yes, most modern smartphones support dual SIM functionality with one physical SIM and one active eSIM. You can configure which line handles calls, SMS, and data independently. This allows you to keep your home number active for calls while using the eSIM for cost-effective local data.

Storage capacity varies by device. iPhone 15 models can store up to 8 eSIM profiles. Most Android devices store 5–10 profiles. Only one or two profiles can be active simultaneously. Inactive profiles remain stored and can be re-activated when needed, making it convenient for frequent travelers with profiles from multiple destinations.

Yes. All cellular iPad models from 2018 onwards support eSIM. Samsung Galaxy Tab S8 and S9 series also support eSIM. Many smartwatches including Apple Watch (Series 3 and later) and Samsung Galaxy Watch support eSIM for standalone connectivity without a paired phone.

Regional European eSIM plans typically cover 30–40 countries across Europe. Coverage varies by provider — always verify the specific countries included before purchasing. Most plans cover all major EU destinations plus Switzerland, Norway, and the UK. Some plans extend to Turkey and other non-EU European countries.

With a regional eSIM plan, your device automatically connects to the strongest available network in the new country. There is no manual switching required and no additional charges for crossing borders. The transition is typically seamless, though you may briefly lose signal in remote border areas.

Most eSIM plans allow hotspot/tethering, letting you share your data connection with a laptop or other devices. Some plans restrict hotspot use or count tethered data separately. Check your plan's terms before relying on hotspot for work purposes.

Your eSIM profile remains stored on your device. Simply disable it in settings when you return home and re-enable your home SIM as the primary data line. The profile remains available for your next trip. If the plan has expired, you may need to purchase a new plan, but the profile management process is the same.

Yes. eSIM connections are as secure as physical SIM connections. The profile download process uses strong encryption. For banking apps, note that some banks send SMS verification codes to your registered number — ensure your home SIM remains active for receiving these messages while using the eSIM for data.

Speeds depend on the local network and your plan type. In major European cities on 4G LTE, expect 20–80 Mbps download. On 5G in supported areas, speeds can exceed 200 Mbps. Some budget plans throttle speeds after a threshold. Premium plans on tier-1 networks deliver the best performance.

Yes, if your device supports 5G and the eSIM plan includes 5G access. 5G is available in major European cities including London, Paris, Berlin, Amsterdam, and Madrid. Coverage is expanding rapidly. Not all eSIM plans include 5G — verify before purchasing if 5G speed is important to you.

Several factors can cause slow speeds: you may have exhausted your high-speed data allocation (check your plan's fair use policy), you may be connected to a congested network, or your plan may route through a slower partner network. Try toggling airplane mode to reconnect to the strongest signal. Contact your provider if speeds remain consistently poor.

First, restart your device. Then check Settings to ensure the eSIM is set as the active data line and data roaming is enabled. Toggle airplane mode on and off to force a network search. If the issue persists, check that you are in a coverage area for the plan's partner networks. Contact your provider's support if none of these steps resolve the issue.

Contact your eSIM provider immediately. Some providers allow profile re-download within a limited window (typically 24–48 hours). Others treat profile deletion as permanent and require purchasing a new plan. Always check your provider's policy before deleting a profile, especially if your plan still has remaining data.

Yes, a factory reset removes all eSIM profiles. Before resetting your device, contact your provider to check re-download options. Back up your QR code email as some providers allow re-installation. If you must reset while traveling, contact your provider's support line immediately.

Most travel eSIM plans are data-only and do not include a local phone number or voice calling. This is normal and expected. For calls, use your physical SIM (which may incur international rates) or use VoIP apps like WhatsApp, FaceTime, or Zoom over your eSIM data connection. Some premium eSIM plans include voice calling — check your plan details.
