Progress has turned a regular SIM card into a mini-SIM, a micro-SIM and then into a nano-SIM we most commonly use today. Nano-SIM cards are actually really tiny. They are also compatible with the majority of modern smartphones. However, the world keeps developing. Now it seems like even nano is too much, considering the fact that no SIM card can be inserted into a relatively small device without the loss of ergonomics. ESIM is meant to become an efficient solution to this emerging problem. What is ESIM? ESIM is some kind of system built into a device. Visually, it is a miniature chip that is soldered directly onto the board of a smartphone or other smart gadget. ESIM by eSImPlus is not produced on a physical carrier. It cannot be pulled out or rearranged. The chip stores data and is updated remotely: you can change the operator or number, connect to several tariff plans.
In this article we will look at this innovation more precisely, analyze all the pros and cons of it and compare it with a regular physical SIM card.
Advantages of ESIM
At first glance, the difference between regular SIM cards and ESIM is the format. Instead of plastic, the user gets a virtual number and a tariff plan. But practically, ESIM offers a lot of profitable bonuses, both financial and practical.
For example, roaming abroad from your local providers is a pricey option. Buying a local SIM card is also not as easy as it seems. You can choose a foreign ESIM and a suitable plan in advance, and then activate it without documents and prepayment. In this case, you will be able to make calls, send messages and use the internet when you arrive. What is more, ESIM providers know their target audience. That’s why travel plans are relatively affordable. They also offer different gifts and bonuses to improve your experience. The plans can be easily changed depending on the country you are about to visit. There are even some worldwide plans.
The remote format of activation and data loading is another advantage of ESIM. No need to go to the office, stand in a line and waste your time. ESIM is connected remotely and does not require complex operations with a smartphone, filling out a paper contract, etc. The absence of a plastic embodiment ensures that the user will not lose or damage ESIM. No one will steal your contacts if you forget your SIM card somewhere, you will not have to change it in the operator’s office due to erased tracks or other damage.
ESIM providers usually have their own support teams. These providers don’t usually depend on any country’s time zone, which makes them available 24/7. It is very convenient if you have problems regarding the way your ESIM works. You will have an opportunity to get a quick reply. Local providers don’t usually have support teams like that. So, you have to solve your problems yourself or wait a long time to consult someone.
ESIM is perfect for those who require more than one SIM card. The majority of smartphones don’t support this service. You can have as many ESIMs as you need and combine them with a regular SIM card as well. Moreover, ESIMs are perfect for young businesses, when you have to keep a lot of things in mind and talk to international business partners.
Using ESIMs is also much safer than regular SIM cards. Having a virtual number will give you the opportunity to sign up for any service almost anonymously. Virtual numbers are compatible with the majority of apps and websites which require registration.
Disadvantages of ESIM
In theory, any ESIM is vulnerable to hacking from the outside. 100% security is not guaranteed, despite its good antivirus systems. However, this disadvantage is relative. Basically, there is no point in attacking a regular user. If somebody really needs to hack your phone, they will do that no matter what kind of SIM card or device you use.
The geography of ESIM is pretty broad. However, there are still some countries where the services are unavailable. For example, an iPhone with ESIM will not work in China, in Hong Kong and Macau. By the way, only a small number of Apple’s devices will be able to function normally.
Transferring data from an old phone from a SIM to a new one is not as easy as pulling out a physical card and inserting it into the slot of another device. You’ll have to spend some time on restoring your data.
Can I have ESIM on my phone?
It is important to understand that not every smartphone model supports ESIMs. The service is available only on the flagships of the following manufacturers:
- Samsung;
- Apple;
- Xiaomi;
- Google;
- Huawei.
There are several ways to check if the gadget is equipped with ESIM:
- Study the instructions from the manufacturer;
- To clarify the possibility of connecting to an electronic SIM card in the operator’s office;
- Check in the smartphone settings.
Is it possible to turn a SIM card into ESIM?
Of course. But it all depends on the capabilities of the gadget and the communication services provider.
The easiest way is to contact your provider so that the staff can set everything up themselves. If you are a cardholder, then take your passport with you. But other people need to present a power of attorney certified by a notary.
iPhone owners, unlike Android owners, are really lucky. They can do everything on their own, no need to visit the office. You just need to open the “Cellular communication” item in the settings, then go to the “Convert tariff” section and click on the “Convert to ESIM” button.
After that, the iPhone will turn your physical SIM card into an electronic one. The card is automatically deactivated. When everything is ready, pull it out and restart your smartphone.
ESIM does not turn a smartphone into a new generation gadget, does not improve its performance and does not solve the problems of poor network coverage. But, at some point, this format really saves money and time. Tourists and entrepreneurs will consider ESIM a breakthrough.
