Modern technology has revolutionized the way we travel, making it easier than ever to stay connected no matter where we go. One such innovation is the eSIM, a digital SIM card that allows you to use data plans without the need for a physical SIM card. In this guide, we will explore how to use an eSIM data plan while traveling abroad, providing you with the freedom to stay connected and access essential services wherever your adventures take you.

Understanding ESIM

ESIM Is What?

eSIM, short for embedded SIM, is a revolutionary technology that is transforming the way we use SIM cards in mobile devices. Unlike traditional physical SIM cards, which are removable and need to be inserted into a device, eSIM is a digital SIM card that is embedded directly into the device's hardware.

How ESIM Works

eSIM consists of a small chip integrated into the device, which stores the necessary information to connect to a mobile network. This information includes the International Mobile Subscriber Identity (IMSI) and other network authentication details. The eSIM can be remotely provisioned and activated with carrier profiles.

Advantages of ESIM

  • Flexibility

eSIM allows users to switch between different carrier profiles without needing to physically swap SIM cards. This is particularly useful for frequent travelers or those who want to take advantage of different network plans.

  • Space-saving

Since eSIM is embedded directly into the device's hardware, it eliminates the need for a physical SIM card slot, freeing up space for other components or allowing devices to be slimmer.

  • Simplicity

Activating an eSIM is often as simple as scanning a QR code or using a carrier's app. This provides a more streamlined and hassle-free process compared to traditional SIM card activation.

  • Multiple Profiles

eSIM supports the ability to store and manage multiple carrier profiles simultaneously, allowing users to have multiple phone numbers or data plans on a single device(such as the iPhone XR series and the later phone types).

Device Compatibility

eSIM tech is just widely used in recent years in the mobile device industry, so at present, not all mobile devices are eSIM compatible. Here is a list of eSIM compatible devices(2023) for you to check. Besides, even for the same phone type, the eSIM compatibility may vary in different manufacturing countries such as China(you cannot purchase an eSIM-compatible phone in China except for wearable mobile devices ). So for precise info, you can check with your phone provider.

Locking Contracts

It has to be noted if your phone is locked by your original provider for some reason (the validity of a locking contract is often 2 years or the like, in some cases, you can ask to withdraw the contract in advance by inquiring about your phone customer service). You can check whether your device is unlocked or not .

If your device satisfies the two requirements, CONGRATULATIONS! it means you are all set to get your eSIM!

How to Own One ESIM?

There are generally a few different ways to obtain an eSIM for your phone:

  • Through your Mobile Network Operator (MNO)

Contact your current mobile network operator (MNO) and inquire if they offer eSIM activation for your device. They may provide you with a QR code or an activation voucher to set up your eSIM directly with them.

  • Via an eSIM Provider

Some companies specialize in providing eSIM services and may offer eSIM plans that can be purchased directly from their websites or through their mobile apps. These providers usually offer global coverage and may offer different data plan options to suit your needs.

  • From Offline Stores

Depending on your region and the availability of eSIM services, you may be able to purchase an eSIM from authorized physical mobile business halls. These eSIMs may be associated with specific carriers and may have limitations on compatible devices and regions.
