differences, advantages and disadvantages of both alternatives

Let’s get A comparison between ESIM and SIM cards. The esim They are the successors of the SIM cards, the last step in the evolution of these, so that after getting smaller and smaller over the years, now they disappear.

The ESIM are not new, they have been among us, increasingly present, but it seems that we are at the gates of the final jump in which mobiles will bet exclusively for them. This change is important, because as all technology electronic sims have their advantages, but also several disadvantages that you should know.

Our intention with this article is that if you ever have to choose the same mobile model with normal Sim or ESIM, or if you are between two models each with one of these technologies, you know to what extent one or the other can affect your experience of use.

Differences between ESIM and physical sim

A SIM is that little card that gives you your mobile operator to put it in your device, so that it can make calls and connect to the Internet. The card has The data that allow you to access your phone numberand also the configuration to connect to the mobile internet that you have hired with the operator.

Since its creation in 1991, SIMs have evolved and becoming smaller and smaller. First we pass from the Great Sim to the Minisim, and from there to the Nanosim that we have today in most mobile phones. The last step is that the card is no longer physical and that come integrated into the mobile itselfwhich is precisely the philosophy of the ESIM.

The ESIM is A chip that carries the mobile phone itselfand that you will be able to configure to install the data that the SIM card would normally have. Thus, your mobile will not need to use a module to enter the physical card, and this space can save it to use it in other things, such as increasing battery capacity or putting other extra chips.

Therefore, the physical sim gives you the operator with the necessary data to access the Internet that you have hired with it and make calls, while the ESIM is on your mobile and you install those same data. The difference is that one is a physical support and another a chip inside the mobilewhere you install your operator’s data.

Advantages and Disadvantages of ESIM

ESIM have some notable advantages about conventional SIMs that should be taken into account. For a start, You don’t need to worry about the status of a cardyou don’t have to worry about losing it or when changing it, you fall or break you.

Acting an ESIM to put your operator’s codes is as simple as scanning a QR code or installing a file that they send you by email. This means that You no longer have to wait for a SIM to be sent by mail If you change your operator or hire a new line, because everything can be done online.

In addition, a mobile with this technology Allows you to store several ESIM card profiles. This means that you can have several contracted lines, even more than 10, and then always choose one or two to be actively using. But these can change them whenever you want, that is, you have greater flexibility, something useful for example when you hire a rate to travel abroad.

In addition to this, there are also advantages such as greater securitysince copying the data of an ESIM is not as easy as those of a SIM, you cannot simply take a phone, open the card tray and extract it. Everything is inside the device.

The manufacturers also have some advantages that can repecut in advantages for you. For example, there may be greater security if the mobile gets wet by not having an extra slot. And removing the module of the slot, a space is saved that can make The same mobile model only with ESIM has more battery capacity That the same version with conventional sim slot, although also has SIM.

ESIM also have disadvantages

But ESIM also have some disadvantagessome things that conventional sim cards can do better. While mobile phones live with both technologies, nothing will happen, you can choose which one to use, but everything seems to indicate that the trend will be completely eliminating the SIMs to introduce only the ESIM, that is, it should be taken into account how bad it can also have.

For a start, Changing mobile can be somewhat more cumbersome. Just as making a migration is easy, changing mobile phones reusing your ESIM is not as easy as taking your card from one device and putting it in the other. There are some manufacturers that have data migration processes from one device to another that include this data, something that should be with modern android and iPhone.

When you change mobile using the same operating system, this is usually easy, since modern android and iPhone have data migration systems that usually include ESIM. But when you change the manufacturer or operating system, there may be some extra steps, and you will even have to ask for help from your operator.

For example, you may need to be issued a new QR or duplicate installation file, and here each operator has its policy, there may be cases where you have to pay to have another duplicate. This can be a special problem in other cases, such as when you want to make the equivalent to simply pass the card from one mobile to another for a moment or a few days, or then return it to the previous one.

Therefore, A SIM card has greater flexibility When making changes between devices. And also greater compatibility, since if you go to ESIM and want to continue using them, you will always need to have a mobile that supports this technology, although today there should be no problems.
