SIM cards are an essential element to be able to use our mobile and that we have been seeing for a long time. It safely stores our phone number by associating it with a specific operator that provides its services to us.
Although there are many users who, more and more, wonder why we continue to use physical SIM cards when there are alternatives integrated directly into the device such as eSIMs. However, not all that glitters is gold, since each one has its advantages and disadvantages.
What information does it contain
SIM cards store highly relevant data related to the telephone number, contacts, operator and billing information.
It also includes the numerical code of the country where it comes from, the IMEI and the status of the card. Also, some media claim that it contains private information such as bank accounts. Hence, hackers try to access it.
At the end of the day, this card is only a way to identify the user and that he has access to the GSM networks.
Is an eSIM better?
As we mentioned at the beginning, each one has its pros and cons . So there is not a completely clear option. SIM cards continue to be used since they have certain advantages over eSIMs, mainly due to issues related to accessibility . That is, it is comfortable for everyone and allows us to transfer data just by changing the terminal card.
The fact that the SIM card is removable means that it can be reused in a different terminal , although this may cause the device not to recognize it. While, in the case of eSIM, the same is not true. To transfer our data in this case we would have to access the cloud to download it. So if, coincidentally, we do not have a backup copy of the phone, we could lose all the information . This would also be a problem for the elderly, since it would involve quite complex processes for them.
Along the same lines, if our phone runs out of battery we could integrate the SIM into another mobile device to be able to use it. A totally impossible faculty with an eSIM.
Although in other aspects it is preferable to use an eSIM due to the extra security it provides. This is much more difficult to hack, since cybercriminals have to go through a security process to get into the data on our terminal. If we use a stream, hackers could have access to all of them only with a password recovery text.
Being physical can also bring wear and tear problems , although this is not usual, since if it is inside the mobile it will hardly suffer a scratch. Unless you are prone to letting the device do.
