An eSIM or embedded SIM is a programmable chip that is embedded in a mobile device and serves the same purpose as a traditional SIM card. Unlike a physical SIM card, an eSIM does not need to be physically removed from or inserted into the device as it is built into the device itself.

With an eSIM, users can activate a data package without having to buy a physical SIM card or visit a store. The eSIM is programmed via a QR code or a website with the details of the data package. This enables a more streamlined and convenient process for activating and managing mobile plans.

For example, users can easily switch between different data packages on different eSIMs without having to physically replace the SIM card. In addition, eSIM technology enables smaller and more compact devices, as no conventional SIM card slot is required.

A data bundle is a package of mobile data offered by a mobile network operator or service provider at a specific price. Data bundles are usually sold in different sizes (1GB, 3GB, 5GB, 10GB, 50GB etc.) and can be used with an eSIM to access internet-based services.

When you buy a data package, you receive a certain amount of data that can be used within a certain period of time. When the data is used up or the validity period has expired, you can simply buy another package.

With an eSIM, the purchase and activation of a data package is carried out online. This means that you can buy and activate a data package directly on your device without visiting a store or waiting for a physical SIM card to arrive in the post.

E SIMs can be installed before or after arrival at your destination. Data will only be consumed from the data packet in the queue when data roaming is activated and you are in a region where the data packet works. The validity period of the WiNG eSIM should be taken into account when traveling. E SIMs and data packages have different validity periods.

You can check the status of your current eSIM and data packets by logging into your Wing eSIM account. Our WiNG eSIM is valid as follows:

• The eSIM expires 12 months after the last data usage
• The data bundle is valid for up to 12 months as long as it is in the eSIM bundle queue.
• The data package expires after a 7- or 30-day counter as soon as data usage is started for the first time.
  

You can continue to use the same eSIM.

You just need to top up another data package to your original eSIM via the portal and you can continue to use the already installed eSIM with your newly added data package. By adding data packages to the same eSIM, you can easily ensure that you always have an internet connection.

You cannot make regular network calls or send text messages with your eSIM. However, you can keep your existing SIM card active if you want to continue using these services. Just make sure you check the charges with your network operator before you travel.

And remember that although WiNG eSIM tariffs are designed for data only, you can still use messaging and voice apps such as WhatsApp, Messenger, iMessage and others.

eSIM technology is now widespread. Most modern mobile devices from leading brands such as Apple, Samsung, Google and Microsoft support eSIM functionality. This integration into a wide range of smartphones and tablets ensures that you can easily access data connections without having to replace a physical plastic SIM card.

When you purchase the eSIM via your smartphone, it is checked directly whether the device is compatible. If you buy your WiNG eSIM via another device, please use our overview to check whether your device is compatible.
