Brief description of SIMs

I think most people who have a cell phone are familiar with those little cards that you insert into the phone and allow you to get internet or make calls.

These cards are just the SIM card or SIM chip.

Before showing you what eSIMs are, I will quickly explain what normal SIMs are, this will allow you to better understand what the advantages and disadvantages are between the two.

The SIM chip means “subscriber identification module” in Spanish, subscriber identification module.

This small chip contains all the information related to your cell phone contract, includes who your provider is, what type of data or calling plan you have and even saves some phone numbers from your contacts (the latter is being replaced by cloud backups)

Basically this small chip is what allows your cell phone to make calls and receive internet without having to be connected to a WiFi network.

One of the main characteristics of SIMs, and why they have become so relevant, is that they are a physical and interchangeable object.

You can remove it from one phone and insert it into another or on a tablet without much trouble and you can immediately use that phone with your current calling and data plan; even get some of your contacts saved on the chip.

But this technology has certain limitations and drawbacks that eSIMs help to solve, but before going into these differences, you need to know what eSIMs are.
