Until now, we have been dependent on SIM cards in the traditional form, i.e. a piece of plastic with a microchip. Anyway - we got used to such a solution because the mini card we all know was introduced in the 90s. Technological development and digitization are progressing faster and faster, and the next generations of SIM cards have become smaller and smaller, starting from the mini, through Micro to nano until now, when we are on the verge of introducing eSIM.
Probably no one is surprised by the fact that large plastic cards with a built-in microchip have been left behind for a long time. Over time, people want to make their lives easier as much as they can and want to follow new technology. Will eSIM completely replace traditional SIM cards? With time, probably yes, but a lot depends not only on smartphone manufacturers but also on mobile operators. Before we discuss how to do it, we will try to explain the topic of eSIMs, what is it really? and how does it work?
An eSIM card ( Embedded SIM ) is simply a small module with a chip measuring approx. 5 × 6 mm permanently installed in a given device. The eSIM card is also known as a digital SIM card or an electronic or virtual card. It is a convenient and flexible solution, more on that below. The solution seems to be a natural step in the advancement of mobile technologies and the evolution in the digitization of the whole world. What's more, the eSIM solution has already been introduced in individual devices by several of the world's largest manufacturers, including the Polish mPTech! We offer an interesting model myPhone with eSIM - myPhone Now eSIM and two reinforced and versatile HAMMER smartphones with eSIM - Blade 3 and Explorer PRO.
For the full use of eSIM, although it is built into a smartphone or other device, it is necessary to support the mobile operator and provide eSIM-related services. eSIM and a given profile are generated by the operator in the form of a QR code, but it can also be implemented manually, but it is always dependent on the services of a given network. Only then is the standard network connection possible but in a completely new version? eSIM allows you to create a unique user profile and encode all data virtually. This brings many benefits - for example, the operator's offer can be almost completely personalized to your own needs, and in the event of changes or updates, they can be carried out remotely, without visiting the showroom.
To implement the changes, all you need to do is download the appropriate data, which we will encode on your smartphone, - this process takes place in the OTA ( Over-the-Air ) system. As a result, eSIM also allows easier and faster change of services and the operator itself (you no longer need to physically insert SIM cards or order a starter kit when changing the operator). What's more, eSIM allows you to use the services of several operators in parallel on one module (chip in the phone). At the same time, eSIM eliminates a number of difficulties: no need to open a card slot or, for example, no need to cut the card to the nano format.
For this reason, eSIM should be successfully adopted not only in smartphones and phones but also in smart gadgets and smartwatches.
A smartphone or phone with eSIM has many advantages, and the ones mentioned above are just the beginning. eSIM provides benefits such as:
And these are probably not all the benefits of eSIM. The technology itself is very developmental and further features and advantages will probably appear over time, with the growing popularity of technology and the growing involvement of operators.
You can also do it in another way by entering your iPhone settings, see the tutorial below to learn how to do it.
To transfer a physical SIM card to a new eSIM:
Now, to complete the eSIM transfer process, you need to approve it on the previous iPhone that is currently using this mobile subscription. If you don't already have your previous iPhone, contact your network operator to transfer your cellular plan.
1. On your new iPhone, go to Settings > Cellular > tap Add Cellular Plan.
If your eSIM plan is available, you'll see it listed. If you don't see your cellular plan listed, check your Apple ID login and two-factor authentication. Then follow the instructions below or contact your service provider.
2. Tap an available cellular plan, then tap Add Cellular Plan at the bottom of the screen.
3. On your previous iPhone, a message will appear asking if you want to transfer your phone number to your new phone. Tap transfer. Once you tap transfer, the cellular plan will no longer be available on your previous iPhone. Your previous iPhone needs to be near your new iPhone to complete this process.
4. If the Finish setting up your carrier's mobile plan banner appears on the new device, tap it.
5. Tap Continue. You will be redirected to the website of your operator to move your eSIM. If you need help, contact your service provider.
6. The final step is to make a call on the new iPhone to check cellular connectivity before removing the cellular plan from the previous iPhone. If you have any additional questions, please contact your operator.
1. On your new iPhone, go to Settings> Cellular> Cellular Plan.
2. The next screen lists the previous iPhone with a physical SIM card. Now tap on your phone number to continue. If you don't see your cellular plan listed, check your Apple ID login and two-factor authentication. Then follow the next steps in the manual. If there is a problem at this stage, contact your mobile operator.
3. At this stage, your new iPhone asks you to confirm if you want to convert the physical SIM card from the previous iPhone to eSIM on the new iPhone. Tap Convert Cellular Plan to confirm.
4. If you intend to use Dual SIM in the future, then you need to remove the physical SIM card from the previous iPhone and install it on the new iPhone without converting it to an eSIM. Otherwise, tap Convert to eSIM.
5. Now click OK on the alert that says you need to approve the transfer on your previous iPhone. In case you don't have a previous iPhone, contact your carrier to transfer your plan.
6. On the old iPhone, click the Transfer button to confirm that you want to transfer the cellular plan and number from the physical SIM card to the eSIM on the new iPhone.
Now all that's left to do is wait for the activation of the cellular plan on your new iPhone. Your old SIM card is now deactivated after activating the cellular subscription on the new iPhone.
