Over the years, technology has developed better and more avant-garde. So, previously, SIM cards were improved only in size: standard, mini, micro, and nano. When it seemed there was nowhere to shrink the SIM card, it was time to abandon it altogether.
For several years now, sales of eSIM-enabled smartphones have been growing worldwide. The eSIM is a technology that allows you to use communication services without installing a physical SIM card, since, in this case, the cellular module is already integrated into the device. So, just select the appropriate tariff, and that is it.
Thus, we have reasons to suggest a physical SIM card will soon be replaced by a digital SIM. However, even this bright technology has its advantages and disadvantages of eSIM. Let’s see what eSIM is, how it works, and what positive and negative sides it has.
eSIM Technology — Exploring
An embedded SIM (eSIM) is a small chip, approximately 5×5 mm in size, that is built inside the device and performs the functions of a SIM card. Initially, given technology was used in industry, however, after evaluating its advantages, many mobile phone manufacturers began to introduce such chips into their gadgets.
Although the eSIM is much smaller than a plastic SIM card, it can also store the same amount of user data for identification on the mobile network. In addition, all user data is stored in the cloud, making it more flexible and user-friendly. Thus, the information on the eSIM card can be overwritten at any time, and the phone number, data plan and carrier can be changed effortlessly.
Besides, digital SIM cards are convenient when traveling abroad: in order not to overpay for roaming, tourists purchase profitable eSIM plans without visiting a physical store.
Popularization of this technology is also beneficial for operators: there is no need to make plastic SIM cards, rent premises for retail outlets, and pay for dealer services.
eSIM Activation & How Does It Work?
The sequence of actions for eSIM activation is almost identical for all devices. Therefore, to enjoy the benefits of the new technology, follow the steps below:
- Firstly, Check with your mobile operator whether your tariff plan supports eSIM technology, and claim a QR code from the operator.
- Then, make sure your device also supports a digital SIM card. To do this, open “Settings” → “Connections” → “SIM Card Manager”. If there is an option in the menu “Adding a mobile data plan”, then you can activate an eSIM plan.
- Click “Add a mobile data plan” button.
- Pick “Add with QR Code” or “Add with activation code” – depending on what you have.
- Follow the on-screen guide.
Warning! An identification code may also be required to activate an eSIM. You find it: “Settings” → “Phone Information” → “Status” → “EID”.
If you do things right, from now on, make calls, send messages, and search the Internet without a plastic SIM!
Pros & Cons of Using eSIM
There is no doubt that the new technology, which is supported by all major mobile carriers, opens up new opportunities. But to be objective, we have collected the most important advantages and disadvantages of using eSIM.
Main Advantages of using an eSIM
So, if you’ve switched to eSIM, here are your benefits from the new technology:
- Easy to use. eSIM does not require physical media, which makes it more convenient for users. It does not take up space in your pocket or bag, which allows you to carry the device without restrictions. To activate it, you only must have the appropriate gadget and a QR code from your mobile operator. You will connect to your data plan remotely in 5 minutes.
- High level of reliability. Why esim is the best solution? An electronic SIM card is more secure than a paid SIM card. It cannot be stolen or lost because it has no physical carrier. In addition, it does not contain personal information such as a phone number or email address.
- Flexibility. Electronic SIM solutions allow you to use different mobile networks and operators, which makes the device more versatile. The users can choose the most suitable tariff plan and operator for their needs.
- Theft protection. An electronic module is protected from theft as it has no physical media. For example, if, unfortunately, your device is lost or stolen, you can fix this quickly by deleting the eSIM and using another device.
- Cheap price. Savings on roaming services will become another benefit for users, since when traveling abroad, one can instantly connect to profitable eSIM tariffs. Operators usually publish eSIM services and special offers for travelers.
Main Disadvantages of using an eSIM
Now, let’s look at the disadvantages of eSIM technology:
- Restriction in the choice of a mobile operator. Today, there are still not many operators that support the eSIM format, so the choice of available eSIM profiles may be limited.
- Hacking the cloud. Although eSIM provides security and reprogramming capability, there is a problem of hacking the cloud hosting the eSIM, and in addition, it cannot be physically removed from the device.
- There may be problems with transferring the number. Sometimes users face the difficulty of transferring a number from an old SIM card to an eSIM. This process is still insufficiently worked out by some mobile operators.
- Not all modern gadgets support eSIM technology. To setup eSIM plan, you need to have a compatible device, which limits the choice of device models for users.
Summary
So, let’s summarize all the things mentioned above. An eSIM is a new technology that offers several advantages over conventional labeled SIM cards. A digital SIM card makes telecom services more convenient and economical. However, not all operators and devices support this technology yet. Therefore, if you are still just thinking of switching to an eSIM tariff plan or not, first carefully study all features about eSIM, its advantages and disadvantages for a particular case. And, of course, find out if your device supports this IT solution.
