Does the Gigaset Gx4 Pro have eSIM?

Yes, the Gigaset Gx4 Pro has eSIM support built in. It offers one eSIM slot and one physical nano-SIM slot, so you can use both simultaneously for dual-SIM functionality. This configuration works well for travelers who want to add a local data plan or anyone who needs to manage two phone numbers on one device.

Can I use two eSIMs at the same time on the Gigaset Gx4 Pro?

No, the Gigaset Gx4 Pro does not support dual eSIM. You can use one eSIM and one physical nano-SIM at the same time, but only one eSIM profile can be active. If you need to switch eSIM providers, you'll have to delete the current eSIM and install a new one, though your physical SIM remains unaffected throughout.

Is the Gigaset Gx4 Pro good for travel?

The Gigaset Gx4 Pro is excellent for travel, especially if you need a rugged, reliable device. Its IP68 rating protects against water and dust, and the eSIM capability means you can add a local data plan without swapping physical SIM cards. The large battery and durable construction make it well-suited for outdoor adventures, remote work, or anywhere connectivity and toughness matter.

How do I remove an eSIM from my Gigaset Gx4 Pro?

To remove an eSIM, open Settings > Network & internet > SIMs, select the eSIM you want to delete, and tap Erase SIM or Delete. This permanently removes the eSIM profile from your phone. If you need to use that plan again later, you'll have to reinstall it using a new QR code, so only delete an eSIM if you're sure you won't need it.

What should I do if the eSIM QR code won't scan?

If the QR code won't scan, try cleaning your camera lens and ensuring you have good lighting. You can also enter the activation details manually by tapping Enter code manually and typing in the SM-DP+ address and activation code. Make sure you're connected to Wi-Fi, and restart your Gigaset Gx4 Pro if the problem persists. Contact your eSIM provider if manual entry also fails.

Gigaset Gx4 Pro eSIM — Compatibility & Setup

Does the Gigaset Gx4 Pro support eSIM?

Gigaset Gx4 Pro eSIM compatibility

Yes, the Gigaset Gx4 Pro supports eSIM. This rugged smartphone includes native eSIM capability alongside a physical nano-SIM slot, giving you flexible dual-SIM functionality. You can run one eSIM profile and one physical SIM card simultaneously, making it practical for separating work and personal lines or adding a local data plan when you travel.

The eSIM support is built into all Gigaset Gx4 Pro models, so you don't need to worry about regional variants or special editions. The device is designed for demanding environments—IP68 water and dust resistance, drop protection, and a long-lasting battery—while still offering modern connectivity features including eSIM.

eSIM vs physical SIM on the Gigaset Gx4 Pro

The Gigaset Gx4 Pro does not support dual eSIM configurations. You can use one eSIM and one physical nano-SIM at the same time, but you cannot run two eSIM profiles simultaneously. This setup still covers most dual-SIM needs: keep your primary number on the physical SIM and add a travel eSIM for data when you're abroad, or use the eSIM for a secondary line and your main carrier on the physical slot.

How to set up an eSIM on the Gigaset Gx4 Pro

Set up an eSIM in Settings

Setting up an eSIM on your Gigaset Gx4 Pro takes about a minute once you have your QR code from your carrier or eSIM provider. The process is straightforward, and the phone will guide you through each step. Make sure you have a stable Wi-Fi connection before you begin, since the eSIM profile needs to download and activate.

Open Settings on your Gigaset Gx4 Pro and tap Network & internet.
Tap SIMs or Mobile network, then select Add mobile plan or Download a SIM instead?
Choose Scan a QR code and point your camera at the QR code provided by your eSIM carrier.
Wait while the eSIM profile downloads and installs—this typically takes 30 to 60 seconds.
Once installed, label your eSIM line (e.g., "Travel Data" or "Work") so you can easily identify it.
Set your preferences for calls, SMS, and mobile data—decide which SIM handles each function by default.

Managing your eSIM profiles

After installation, you can turn your eSIM on or off in the SIMs menu without deleting it. This is useful if you want to pause a line temporarily or switch between eSIM profiles (though you'll need to delete one eSIM to install another, since the Gigaset Gx4 Pro holds only one active eSIM at a time). Your physical SIM continues to work independently, so you can always fall back to it if needed.

Using a travel eSIM on the Gigaset Gx4 Pro

A travel eSIM is one of the easiest ways to stay connected when you're abroad without paying roaming fees on your home carrier. Instead of hunting for a local SIM card at the airport or dealing with expensive international plans, you can browse eSIM plans for your destination, purchase one online, and install it on your Gigaset Gx4 Pro before you leave. The eSIM activates when you land, giving you instant data access.

Install your travel eSIM before departure

Install your travel eSIM while you're still at home and connected to Wi-Fi. The profile will sit dormant on your phone until you arrive at your destination and turn on data roaming for that eSIM line. Your home SIM stays active for calls and text messages, and you can keep it on for two-factor authentication codes while using the eSIM exclusively for data. This setup keeps your usual number reachable and your data costs predictable.

The Gigaset Gx4 Pro's rugged build makes it a reliable travel companion—waterproof, shockproof, and ready for demanding conditions—and the eSIM flexibility means you can hop between countries without carrying multiple physical SIM cards or worrying about losing a tiny piece of plastic.

Tips & troubleshooting

Turn on data roaming for the eSIM line

After you install your travel eSIM, you need to enable data roaming specifically for that line. Go to Settings > Network & internet > SIMs, select your eSIM, and toggle Roaming on. This won't trigger roaming charges on your home carrier because you're using a separate data plan. Your physical SIM can stay on for calls and texts, or you can disable data on it entirely to avoid accidental roaming fees.

Fix an eSIM that won't activate

If your QR code won't scan, check that your camera lens is clean and the lighting is adequate. You can also enter the activation code manually: tap Enter code manually during setup and type in the SM-DP+ address and activation code provided by your carrier. If the eSIM downloads but won't activate, restart your Gigaset Gx4 Pro and make sure you're connected to Wi-Fi or have a stable data connection on your physical SIM.

If you continue to have trouble, eSIM setup help is available, or contact your eSIM provider directly—they can sometimes resend the QR code or check that the profile hasn't already been installed on another device. If you're not sure whether another phone in your household supports eSIM, you can check another device's eSIM compatibility before purchasing a plan.

Keep your home SIM for calls and 2FA

The dual-SIM setup on the Gigaset Gx4 Pro lets you keep your home number active for incoming calls and two-factor authentication texts while routing all data through your travel eSIM. In the SIMs menu, set your physical SIM as the default for voice and SMS, and set the eSIM as the default for mobile data. This way, you stay reachable on your usual number without paying for international data roaming.
