Step 1: Check Device Compatibility

Before diving into eSIM setup, you need to ensure your phone supports eSIM technology. The process to verify this can vary depending on your device manufacturer. One quick way to check is by using a simple code: dial *#06#. This will display both your IMEI number and, if your phone is eSIM-compatible, an EID (a unique identifier for eSIMs).

Checking Through Device Settings

Different manufacturers place eSIM settings in various sections of the menu. Look for an option like "Add eSIM" to confirm compatibility. Here’s how to find it on popular devices:

iPhones: Navigate to Settings > Cellular. If you see "Add eSIM", your device is compatible. All iPhone models from the XR and XS onwards include this feature.
Samsung Galaxy devices: Go to Settings > Connections > SIM card manager (or SIM Manager). If "Add eSIM" is listed, your device supports eSIM.
Google Pixel phones: Head to Settings > Network & Internet > Advanced. Tap the "+" icon and look for "Download a SIM instead?" Alternatively, check for an "Add Operator" option .
Huawei devices: Look under Settings > About Phone > Show EID. If an EID is visible, your device is eSIM-compatible. You might also find eSIM settings under Settings > Mobile Networks > SIM Management.

Here’s how to check for updates:

iPhone: Head to Settings > General > Software Update
Android devices: Go to Settings > System > System Update (note that the exact path might vary depending on the manufacturer).

Ensure a Stable Internet Connection

A strong and reliable internet connection is crucial for downloading the provider profile. Connect to a robust Wi-Fi network to avoid interruptions during the process.

Gather Your ZIM Connections eSIM Details

After purchasing your ZIM Connections eSIM plan, you’ll receive an email containing a QR code. Keep this email handy, as it includes all the information needed for activation.

You can access your activation details in two ways:

QR Code Method: Use the QR code provided in your email.
Manual Entry Method: Locate the SM-DP+ Address and activation code in your ZIM@SBB app wallet under the "eSIM settings" section.

Timing Your Installation

It’s a good idea to install your eSIM profile 1–2 days before your trip. This allows time to resolve any unexpected issues. Additionally, service providers can send over-the-air updates to your eSIM profile, ensuring you receive the latest connectivity improvements, security updates, and performance enhancements.

Once your device is updated, connected to the internet, and you have all your eSIM details ready, you’re all set to move on to the next steps for installation.

Step 3: Install the eSIM in 5 Steps

Setting up your ZIM Connections eSIM is straightforward and can be done in just five steps.

Purchase and Receive Your eSIM Plan

Start by selecting the ZIM Connections eSIM plan that best suits your needs on our website or mobile app. Once you’ve made your purchase, you’ll instantly receive an email containing all the necessary details, including a QR code and manual activation instructions. Since everything is delivered digitally, there’s no need to wait for physical delivery or visit a store. To maximise the validity of your eSIM, consider purchasing it in advance and activating it closer to your departure date.

Access eSIM Setup on Your Device

The process for finding the eSIM setup menu may vary slightly depending on your device, but the general steps are similar.

For iPhone users: Go to Settings > Mobile Data > Add eSIM. You’ll find options to add a new mobile plan by scanning a QR code or entering details manually.
For Android users: Head to Settings > Network & Internet > SIMs > Add eSIM or Settings > Network & Internet > Mobile Network > Add. The exact wording might differ depending on your device’s manufacturer. If prompted with "Don’t have a SIM card?", simply tap Next to proceed.

Once you’ve located the setup menu, you can scan the QR code or manually enter the details to continue the installation.

Scan the QR Code or Enter Details Manually

Using the QR code is the quickest way to install your eSIM. Open your device’s camera and position it over the QR code in your ZIM Connections email. Your device should automatically detect the code and prompt you to add the eSIM.

For iPhone users with iOS 17.4 or later: You can also press and hold the QR code directly in your email or a webpage, then select Add eSIM.
If the QR code doesn’t work, you can manually enter the SM-DP+ address and activation code.

Manual entry on iPhone: Go to Settings > Cellular/Mobile Data > Add Cellular Plan > Enter Details Manually.

Manual entry on Android: Navigate to Settings > Network & Internet > Add (or tap the + icon next to Mobile Network) > Enter Code Manually.

Download and Install the eSIM Profile

After scanning the QR code or entering the activation details, your device will automatically download and install the eSIM profile. This process typically takes just a few minutes, depending on your internet connection. During the installation, you’ll see a progress indicator – be sure not to exit the settings menu while the download is in progress.

Once complete, you’ll receive a notification confirming the successful installation, and the new eSIM will appear in your mobile network settings.

Activate and Configure Your eSIM

The final step is to activate your eSIM and set it up according to your preferences. You can choose whether to use the ZIM Connections eSIM as your primary or secondary data line.

If you’re travelling internationally, make sure to enable Data Roaming under the eSIM profile. You can also configure your call and text settings, deciding which line to use for voice calls, SMS, and mobile data. Many users opt to keep their home SIM for calls and texts while using the eSIM exclusively for data.

Once activated, your ZIM Connections eSIM is ready to use. Activation typically happens automatically when you arrive at your destination, but you can also enable it manually through your device’s mobile network settings before you travel.

Troubleshooting Common eSIM Issues

Even after carefully following the installation steps, you might run into some common problems when setting up your ZIM Connections eSIM. The good news? Most of these issues have straightforward fixes. By identifying the root cause, you can save yourself time and effort. Below is a handy guide to some frequent eSIM problems and their solutions.

Common Problems and Solutions

The majority of eSIM issues arise from device compatibility, network connectivity, or incorrect settings. Here’s a quick reference table to help you troubleshoot:

Tips for Using eSIM While Travelling

Travelling with an eSIM can make staying connected much easier, but a few smart steps can help you avoid unexpected costs and technical issues. Here’s how to make the most of your ZIM Connections plan while keeping things hassle-free.

Avoid Roaming Charges

To steer clear of unexpected roaming fees, disable your primary SIM before activating your eSIM abroad. This ensures your home network doesn’t charge you for roaming while your eSIM handles all your data and calls.

iPhone users: Go to Settings → Mobile Service and turn off data and roaming for your primary SIM.
Android users: Head to Settings → SIM cards & mobile networks to find similar options.

Also, turn off automatic network selection on your primary SIM. This prevents your phone from accidentally connecting to your home network. For added convenience, set your eSIM as the default line for mobile data in your phone’s settings, ensuring all internet traffic is routed through your ZIM Connections plan.

Your eSIM can do more than keep your phone connected – it can turn your device into a portable Wi‑Fi hotspot. This allows you to share your data connection with laptops, tablets, or other devices. However, not all eSIM plans support this feature, so double-check that hotspot sharing is included in your ZIM Connections plan.

Setting up a hotspot is straightforward:

iPhone: Navigate to Settings → Personal Hotspot and toggle it on.
Android: Go to Settings → Network & Internet → Hotspot & Tethering.

Make sure to create a strong, unique password to secure your hotspot from unauthorised users. Keep an eye on your data usage, as connected devices can quickly eat through your allowance. To save data, disable automatic updates on laptops or tablets and limit background apps that sync data.

Hotspot sharing can drain your phone’s battery faster than usual, so carry a portable power bank to stay powered up when you’re on the go.

Keep a Backup of Activation Details

It’s always wise to have a backup of your eSIM activation details. Save a digital copy of your eSIM QR code and activation information before your trip. You can store screenshots in your photo gallery, email them to yourself, or upload them to a cloud service like Google Drive or iCloud.

For extra security, print a physical copy of your activation details, including your order confirmation number and ZIM Connections customer support contact information. This can be incredibly useful if your phone gets lost, stolen, or damaged.

Travelling with others? Share your activation details with a trusted companion. They can assist you in reinstalling your eSIM or contacting support if needed. Just ensure these details are stored securely, as they contain sensitive information.

Before you leave, test your backup plan. Temporarily remove and reinstall your eSIM profile using your saved details to make sure everything works as expected. This way, you’ll be prepared and confident in handling any technical hiccups while travelling.

FAQs

What can I do if my phone doesn’t show the option to add an eSIM in the settings?

If your phone doesn’t show the option to add an eSIM, there could be a few reasons behind it, such as carrier restrictions, regional settings, or software glitches. First, double-check that your device supports eSIM and that your mobile network provider offers eSIM services.

How can I make sure my eSIM works smoothly when travelling abroad?

To make sure your eSIM works smoothly while you’re travelling abroad, start by confirming that your device supports eSIM functionality and is compatible with the networks in your destination. Also, double-check that your eSIM plan covers all the countries on your itinerary.

Before you set off, enable data roaming and adjust your local network settings if necessary. Download any required carrier profiles ahead of time and go through the activation instructions provided by your eSIM provider. Preparing in advance can help you steer clear of connectivity hiccups and enjoy uninterrupted service during your travels.

Are there any security risks to be aware of when using an eSIM for mobile data?

While eSIMs are considered secure, there are a few risks worth noting. One issue is SIM swapping, where scammers convince your network provider to transfer your phone number to a different device.
