eSIM: What Is It And How Does It Differ From a Plastic SIM Card
Every phone has a SIM card. This is a module that connects the subscriber and the operator and also allows the user to use cellular communications. And each one is unique.
SIM cards come in different sizes. Modern smartphones use Nano SIM, the smallest format in plastic. Most likely, this is exactly what is installed on your device. Older phone models are suitable for other, larger ones.
eSIM (embedded SIM) is a type of SIM card that is built directly into a smartphone. You don’t need to buy such a digital SIM card separately, worry about installing it in the case, and then change the number and repeat it all over again. It is already inside the device and will always be there. All the user needs to do is select an operator and connect a tariff via smartphone. No office visits or paperwork.
Pros And Cons Of eSIM
It is immediately clear that a digital card is much more convenient than its plastic ancestors. One of the advantages of eSIM as we have already revealed above is fast connection. Now let’s figure out what else this technology can offer:
- Durability. The electronic SIM card cannot be removed from the case, which means it cannot be broken, lost, or stolen. It will serve you from the day you purchase your smartphone until the moment you replace it with a new one.
- Versatility. A regular SIM stores only one number, but up to 5 can be connected to the built-in SIM. And there are no problems because there are many numbers and few slots for them.
- Safety. This SIM cannot be transferred to another phone. This means that scammers will not be able to steal your number or throw away your card if they happen to have a smartphone. It will be much easier to track the loss.
- Use of repeaters. You can use boosters to improve your mobile signal. For example, if you have a Tesco mobile poor signal, you can switch to Vodafone and additionally use a repeater.
At the same time, eSIM is beneficial not only to the subscribers themselves but also to telecom operators. This technology allows them to buy fewer chips because people will only use one SIM instead of changing them several times.
However, even such a convenient thing has a downside. eSIM may not be right for you because:
- built-in SIM technology is not yet so widespread, so very few devices have this function;
- if the phone breaks, you can lose data from the eSIM;
- contracts for such services are concluded remotely using biometrics, so users who are against the collection of such data will not like eSIM.
Compare the pros and cons for yourself, without relying on other people’s opinions and experience of use. This way you will understand whether you will be comfortable switching to eSIM technology.
How To Enable eSIM
You can buy an electronic SIM card at the operator’s office. But there is no reason to go there because everything can be done at home yourself. The first thing you need to do is go to the operator’s website, select, and pay for a mobile tariff. In the UK they are offered by mobile operators such as EE, Lyca Mobile, O2, Three & Vodafone.
When the payment is successful, the operator will send you instructions on how to activate the number. But if surprises are not for you, we will tell you in advance what you will need to do. There are separate instructions for each OS.
Instructions For iPhone
To activate the built-in SIM, prepare information from your operator. Further:
- Connect to the Internet.
- Go to “Settings”.
- Find the “Cellular” section.
- Tap on the “Add cellular tariff” item.
- When the camera opens, point it at the operator’s QR code.
The steps you need to follow next depend on the carrier you choose.
Instructions For Android
In the same way, prepare a QR code from your mobile operator and other data. Then:
- Connect to the Internet.
- Go to “Settings”.
- Find the “Connections” section and go to it.
- Go to the SIM Card Manager.
- Select Add eSIM.
- Scan the QR code from the operator.
- Follow the instructions below to complete the setup.
The names of the sections where the necessary settings are located depend on the manufacturer and model of your device. They may differ from those we indicated in the instructions. To avoid wasting extra time, use the search settings.
