When it comes to your mobile phone, there are two types of SIM cards: physical and digital. While many older phones still have a removable card, newer models typically feature an embedded SIM (eSIM) instead.
These virtual SIMs allow you to have a number from multiple carriers stored on your phone. Plus, they're easier to manage if you swap phones or want to try a different carrier.
What is an eSIM?
eSIM is the next-generation technology that is transforming mobile phones and other devices. It replaces the traditional physical SIM card tray that's found on most modern phones.
The eSIM chip takes up just a few square millimeters of space and is soldered directly into the phone's motherboard. It offers a number of advantages over the removable SIM card, such as easy switching between network providers and the ability to use a phone's number on other devices.
Another important benefit is the possibility to store plans from multiple networks on one eSIM. This means you can have a personal number and a business number, for example, or a data roaming SIM for travel abroad.
While eSIMs are not yet available on every smartphone, they're becoming increasingly commonplace. Most Apple iPhones, the Google Pixel series, the Samsung Galaxy and Moto Razr, and even some Huawei and Oppo smartphones support them. Moreover, many smartwatches and portable computing devices such as the Galaxy Book Go and Surface Pro X are also eSIM-ready.
How do I know if my phone has an eSIM?
Does My Phone Have Esim?
eSIM is an acronym for “embedded SIM.” It is a new way to load cellular data onto your device. It is an alternative to a physical SIM card and offers a number of benefits.
One of the most important is that it can swap operators instantly. This makes eSIM a great choice for travelers.
You can use an eSIM to stay connected in more than 100 countries worldwide and save money on cellular roaming fees.
To test that your eSIM plan is working, turn off your Wi-Fi temporarily. If you can still get on to new websites and social media apps, your eSIM data is working properly.
Once you’ve checked that, it’s a good idea to double-check your primary plan’s data roaming setting. This will make sure that your home carrier can’t charge you any roaming fees while you are abroad.
How do I check if my phone has an eSIM?
A SIM is a small card that holds your phone number and all the information that connects you to your carrier. Most phones require users to have a SIM card in order to make and receive calls on a wireless network.
Embedded subscriber identity modules, or eSIMs, are digital versions of SIM cards and can be installed on devices that support them. These chips are embedded into the hardware of the phone, so they don't need to be popped out to switch carriers and are more secure than physical SIM cards.
If you have a new high-end smartphone, you should see an option to add an eSIM in the settings of your device. This is because eSIM technology has been adopted by Apple and some other major phone makers, and will become more widespread in the future.
Typically, it takes just a few minutes to add an eSIM, but some networks have taken longer than others to embrace this technology. Luckily, most carriers are catching up quickly and making the transition to eSIM easy for their customers.
How do I add an eSIM to my phone?
Do you have an eSIM but aren't sure how to use it? If so, you're not alone. Most of us switch phones every few years, so we are used to transferring a physical SIM card from one device to another.
You can add an eSIM to your phone in a few easy steps. It won't change your plan, price, photos or data, and it's free.
If you're not sure what to do, check with your carrier for instructions. Some carriers have a QR code you can scan to transfer an eSIM from one phone to another.
This method doesn't work for all carriers, so check if the original QR information and the QR code say something like "This unique QR code is for one time use on 1 device only." If that is the case, contact your carrier and request that they provide you with a new, working eSIM QR code. After that, you should be able to activate your eSIM on the new iPhone.
