Summary:
Our guide covers the following:
Know This First: Who would find an eSIM useful?
- An eSIM is an electronic SIM card embedded within a device's hardware rather than a physical card that can be removed and inserted into a device.
- Because the eSIM is not a physical card, it doesn't need to be swapped or replaced when switching mobile providers; this can all be done with a few clicks on the device.
- Depending on your device, you may be able to have more than one SIM and/or eSIM profile(s) active at the same time.
- Only Spark, One NZ and 2Degrees support eSIM technology in New Zealand. Spark is the only one to offer plans for wearable technology (smart watches with eSIMs), but other providers plan to start offering this service shortly.
- Are you travelling overseas? This guide isn't for you. We suggest reading trusted guides such as the best eSims for international travel and best eSim providers, which list options for anyone travelling in Asia, North America and Europe.
- Do you want to migrate from a SIM card to an eSIM? Spark, One NZ and 2Degrees will make the switch for you in any one of their stores. The activation is free of charge.

Know This First: Who would find an eSIM useful?
- Travellers: eSIMs are ideal for frequent travellers who need to switch between different networks and plans when visiting different countries. With an eSIM, they can activate a new plan and avoid having to purchase a physical SIM card every time they arrive in a new location.
- Internet of Things (IoT) devices: eSIM technology is well-suited for (IoT) devices, such as smart home appliances, wearables, and connected cars. eSIMs can enable these devices to be always connected to a mobile network without requiring a physical SIM card.
- Business users: eSIMs can be useful for businesses with a large number of employees who need to be connected to a mobile network. With eSIM technology, companies can provision multiple devices with the same network and plan, making it easier to manage their mobile communications.
- Remote workers: eSIMs are ideal for remote workers who need to be connected to a mobile network but do not want to be tied to a particular network or plan. With an eSIM, they can easily switch between different networks and plans without having to purchase a physical SIM card or change their device.

What is an eSIM?
- An eSIM is a virtual SIM card that has been pre-installed within a device's hardware. Unlike a regular SIM card, an eSIM cannot be removed from the device. Instead, it is programmed with the necessary information that is required to connect to a mobile network.
- This information is stored in the device's memory and can be updated “over-the-air” (OTA), the process of remotely activating an eSIM card without the need for a physical SIM card.
- With an OTA eSIM activation, the user can simply scan a QR code or enter an activation code provided by their mobile network operator into their device to download the eSIM profile. This eliminates the need for physically inserting a SIM card into a device.
- The OTA process also enables users to switch mobile network operators and download multiple eSIM profiles on a single device without needing to physically change SIM cards.
What’s the difference between eSIM and eSIM profile?
- An eSIM, or Embedded SIM, is a small electronic chip that is embedded directly into a device, such as a smartphone or a smartwatch, and is used to store subscriber identity and network credentials. It is an alternative to the traditional physical SIM card, which is inserted into a device's SIM card slot.
- An eSIM profile, on the other hand, is the digital profile that is downloaded onto the eSIM chip in order to activate a mobile plan. The eSIM profile contains the subscriber's network credentials, such as phone number, data plan, and other subscription details, which are stored in the eSIM chip.
- In other words, an eSIM is the physical hardware component that stores the digital eSIM profile, which contains the user's subscription details. The eSIM profile is what allows the user to activate a mobile plan on their eSIM-enabled device without the need for a physical SIM card.
- Important: Not all devices are compatible with eSIM technology, and not all mobile networks offer eSIM plans. If you're considering an eSIM plan, you should check with your network and device manufacturer to ensure compatibility.
What devices use eSIM technology?
Not all phones offer eSim technology. However, many devices now support this technology, including (but not limited to):

What Should I Consider When Getting an eSIM Plan?
Just as you'd select a phone network, an eSim is not different. Here are some factors to keep in mind:
- Network coverage and reputation: Make sure that the network you're considering has good network coverage in the areas where you'll be using your device. Check their coverage maps as a starting point, and reviews from other users to see how satisfied they are with the network's service will give you an insight to how reliable the service is.
- Data speeds: If you'll be using your device for data-intensive activities like streaming or video conferencing, make sure that the network offers fast data speeds in your area (e.g. 4G or 5G).
- Plan pricing: Compare the pricing of eSIM plans from different networks to ensure you're getting a good value. Look for hidden fees or charges that could add up over time.
- Plan flexibility: Make sure that the network offers plans that are flexible enough to meet your needs; for example, plans that allow you to adjust your data allowance or other features as needed.
- Activation process: Check the network's activation process to make sure it's easy and straightforward. Some networks may require you to visit a store in person to activate your eSIM, while others may allow you to activate your plan remotely.
- Device compatibility: Ensure your device is compatible with the network's eSIM technology. Some networks may only support eSIMs on certain devices, so it's essential to check before signing up for a plan.
