When a new technology comes out, it is always important to compare it before replacing the one you are using, and to understand if it is better to replace it in part or all with the new one.

It is therefore important to make comparisons between the PROs and CONS of the two technologies, and check which could be the most convenient for you at that time and for the following months.

To consider that the change of technology often implies higher costs.

In the case of eSIMs it is necessary to have a Smarphone that allows the use of eSIMs and of course has 5G connectivity.

The SIM, acronym of "Subscriber Identity Module", was born in 1991 when the GSM, acronym of "Global System for Mobile Communication" was developed, to use the communication standard adopted by the European Union in 1987 and therefore make up for the then TACS, acronym for "Total Access Communication System", which was the analogue standard of mobile telephony of the 1G network developed in the eighties (from 1980).

Then, and until the first smartphone release, he turned around with briefcases that contained the telephone handset to make phone calls connected to the device inside the briefcase.

About 30 years have now passed and the SIM is still in effect a valid Smart Card, allowing today communication (voice and data) in 5G, acronym of "5th Generation of Cellular Technology", therefore used by all telephony operators mobile in the world.

Each SIM has a unique telephone number, and is identified with a unique ICCID code, which stands for "Integrated Circuit Card-Identity", which is the 19-digit international code that uniquely identifies the SIM.

The eSIM (or e-SIM) is the acronym for "Embedded Subscriber Identity Module" or SIM cards incorporated into the device, also called Virtual SIM.

The eSIMs were born in 2016 but entered into force when Apple inserted them in its Smartphones in 2018, to which all smartphone manufacturers and consequently mobile operators have subsequently adapted.

The eSIMs have no Smart Card and Chip costs, the latter consisting of raw material that seems to be running out and currently has excessive costs.

With the eSIM communication in 5G has also taken place, even if 5G is also good on SIMs.

As anticipated, the SIM is a Smart Card that resides in a chip that is inserted into the Smarphone, while the eSIM is a virtual SIM that is activated, after the purchase through a QR code received or through codes.

The eSIM is a tiny chip inserted in the smartphone that cannot be removed.

Both technologies can coexist in the same Smarphone.

Both technologies, according to the manufacturer of the smartphone, can work at the same time, therefore have 2 data connections, to be decided which of the 2 to use at the moment, and two telephone numbers.

Although eSIMs have entered the market as an innovative technological tool, in reality there is little difference between SIM and eSIM.

Both SIMs and eSIMs have the function of connecting your Smartphone to a mobile network.

Currently not all mobile networks in the world provide eSIM plans, as not all of them provide 5G.

Both, activated, allow you to make and receive calls, send and receive messages and connect to the Internet.

Both store the information needed to identify your phone, your number and the data plan you are currently using to connect to the internet.

The eSIMs can also be used not only on Smartphones but also with Smartwatches.e anche con gli Smartwatch.

Although eSIMs are a trend, that doesn't mean SIM cards are useless.

Most of the mobile phone companies in the world continue to distribute SIM cards, also because not all users have Smartphones that include eSIMs, surely a few more years will have to pass.

In SIMs today, operators offer more data plans than eSIMs.

The SIM cards are removable, so if my Smartphone breaks down, or I have to change it, and I must always be connected, both with phone calls and with the Internet, just remove the SIM from the Smartphone and insert it in another and it works immediately.

The eSIM cannot be damaged, much less lost, unless the smartphone is lost or broken.

Remember that the "e" of the eSIM stands for "embedded", so the SIM is integrated in the phone, so you cannot remove it, to do this you must deactivate it on the current Smartphone and activate it on another Smartphone, remembering or having the activation codes available.

The security features of eSIMs are much better and will better protect your information from possible hackers.

Let's dispel a rumor about SIM and eSIM

Many competitors declare that only one data plan of a single country can fit on a SIM and eSIM, it is true for most telephone companies, however with BLIVALE's eSIM and SIM you can have multiple data and voice plans at the same time and use what you need it at that moment. Especially for those who travel for work or vacation and need to have data plans (and voice) in the country will have to go.

The cons of SIMs are that they are often not secure, and can be hackable, where you can access and obtain information about your data, such as Social Media, bank accounts.

Certainly there are also protections, and we often have to be careful of SMS or SPAM e-mails that allow, if you click on the proposed link, to access our information.

ESIMs only work with new generation Smartphones. In this case, it is always advisable to buy Smartphones that also include an internet connection in 5G.

As anticipated, the eSIM can only be used on a single Smartphone and to use it on another device you have to take special steps.

Today we recommend the purchase of a Smartphone that provides for both the use of SIMs and eSIMs. Some of them have dual SIM cards and dual eSIMs. Certainly these Smartphones are useful for those who travel, and want the peace of mind of always having the connection.

If you are planning to travel for work or vacation or in Smart Working, get your connectivity with BLIVALE eSIM or SIM: you will no longer have to worry about roaming costs and expensive data plans.

The eSIM is a digital SIM, incorporated into your new technology Smartphone or Tablet that provides 5G, and allows you to activate a data plan without using a physical SIM.

BLIVALE offers thousands of data plans eSIM and SIM for over 200 countries. It's cheaper than your local operator's roaming plans, and you can activate it in minutes by following simple steps.
