How can we help?

An eSIM is a digital SIM built into a compatible device. It allows you to add a mobile plan without inserting a physical SIM card.

A travel eSIM connects your compatible device to supported mobile networks at your destination. You install an eSIM profile and select it for mobile data.

Usually yes. If your phone supports dual SIM, you can keep your regular SIM active while using a travel eSIM for mobile data. Charges from your regular operator may still apply.

Yes. WhatsApp generally continues using your existing account and phone number when you switch your mobile data connection to an eSIM.

A reliable internet connection is normally required to download and install an eSIM profile. Installing before travelling is often convenient, subject to the plan's activation conditions.

Many compatible phones support using an eSIM alongside a physical SIM. The available combinations depend on your device model and software.

Visit Swiftaer's device compatibility page and check your exact model. Availability can vary by country or region of purchase.

Yes. Travel eSIMs generally require a carrier-unlocked device. Contact your current mobile operator if you are unsure.

No. eSIM support depends on the iPhone model and the market where it was sold. Some regional variants have different SIM capabilities.

Many Samsung Galaxy models support eSIM, but compatibility varies by model and region. Check your device's specifications.

Many Pixel models support eSIM. Compatibility depends on the model, carrier restrictions and regional variant.

Some cellular tablets support eSIM. Check whether your exact tablet model supports eSIM profiles and the required mobile networks.

Open your device's mobile or cellular settings and choose the option to add an eSIM. Follow the instructions provided with your eSIM, which may include scanning a QR code or entering details manually.

Installing while you have reliable Wi-Fi before departure is often convenient. Always check the specific plan's activation and validity conditions first.

Activation conditions depend on the plan. Some plans begin validity when installed, while others begin when the eSIM first connects to a supported network.

Some devices and eSIM providers support manual installation using activation details. Follow the instructions supplied with your particular eSIM.

Check that your device is compatible and connected to the internet, and confirm that the code has not already been used. Avoid repeatedly deleting or reinstalling an eSIM without guidance.

Reinstallation is not always possible. Some activation codes can be used only once. Contact the relevant support channel before deleting an installed eSIM.

Some travel eSIMs require data roaming to be enabled on the eSIM line. Follow your plan's instructions and make sure roaming is not accidentally enabled on your regular SIM if you wish to avoid extra charges.

Fixed plans provide a specified data allowance. Unlimited plans may provide continued connectivity subject to daily high-speed allowances, fair usage policies and reduced speeds. Always review the selected plan's conditions.

Not necessarily. Unlimited plans can have fair usage limits, daily high-speed allowances or speed reductions. Check the conditions displayed for your selected plan.

Coverage depends on the selected destination or regional plan. Check the relevant destination page for available options and coverage information.

5G availability depends on the plan, device, local network and coverage. A compatible phone does not guarantee a 5G connection everywhere.

A country-specific plan and a regional or global plan may have different coverage. Review the destinations included in the plan before travelling.

Hotspot availability depends on the plan and local network. Check the selected plan's conditions before relying on tethering.

Many travel data eSIMs provide mobile data only. Calls and messages through internet-based applications may work, but traditional calls and SMS require a plan that explicitly includes those services.

Open your device's cellular or mobile network settings and select the travel eSIM as the mobile data line. Menu names vary between iOS and Android.

Your device may show mobile data usage in its cellular settings. For an authoritative remaining allowance, use the usage information supplied by your eSIM provider when available.

On compatible dual-SIM devices, you can usually change the mobile data line in your phone's settings.

If the eSIM is correctly installed and the plan is valid, it may connect when a supported local network becomes available. Connection time can vary.

Installing a travel eSIM generally does not remove your regular SIM. However, device settings determine which line handles mobile data, calls and messages.

Coverage at sea is not guaranteed by ordinary land-based mobile plans. Check whether your selected plan explicitly supports maritime connectivity.

Check that you are within the plan's coverage area, select the correct mobile data line, review roaming and APN requirements, and restart your connection. Do not delete the eSIM without guidance.

Connection speeds depend on local coverage, congestion, device capabilities and plan conditions. Some Unlimited plans reduce speeds after a high-speed allowance is used.

Confirm that your eSIM is enabled, the plan covers your location and your phone can access a supported network. Try automatic network selection and check the installation instructions.

An Access Point Name (APN) is a network setting used for mobile data connectivity. Some eSIMs configure it automatically; others require details supplied with the plan.

Verify that the eSIM is selected for mobile data, the plan is active, roaming settings are correct and you are within coverage.

No. Avoid deleting an eSIM until you have checked the troubleshooting instructions or contacted support. Reinstallation may not be possible.
