A Comprehensive Guide of Various eSIM Formats & Types

Are you looking for a comprehensive guide to e-SIM technology and providers? You are at the right place. After reading this article, you will know the types of SIMs and their activation methods. SIMs are revolutionizing how we manage our mobile connection and with more providers and career offerings.

Size and format details of Sims

Types of sims 

There are the following types of items. We will discuss the description of each type one by one. and then their activation method 

1- standard SIM

2-Micro SIM

3-nano SIM

4-eSIM

5-iSIM

Standard e-SIM

The main point of a account  is the standard. the use of standard e-sim. These stores in the physical plastic cards that can be transferred between two devices/sims don’t allow profiles to be remotely changed.

This means that network settings or updates must be manually performed.

 

The standard format, aka 1FF, appeared in 1991. the chipp could be compared in size to a bank plastic card. the parameter of standard e\SIMs

The length is 85mm

The width is 53mm 

And the thickness is 0.76mm

Embedded sims pics (items):

While they frequently overlap, embedded SIMs and eUICCs (Embedded Universal Integrated Circuit Cards) have different functions in terms of connectivity. The software that allows the remote provisioning of carrier profiles on the eSIM is known as eUICC, whereas an eSIM is a physically embedded SIM card that does not need a tray or slot in the device. There are several form factors for an eSIM, such as MFF2, 4-in-1, and 3-in-1.

Remote administration and carrier profile switching are made possible by the eUICC software on eSIMs, guaranteeing that the sensors stay connected to the best network carriers no matter where they are in the world without requiring physical assistance. Like a software update, this option to obtain a new profile even permits a modification in the

Thus, while eSIM provides the physical framework for embedded connectivity, eUICC offers the technological capability to manage this connectivity remotely and flexibly across various network providers and regions.

It is important to note, though, that eSIMs, particularly those with eUICC, have a drawback: since the eSIM depends on connectivity to function, you are unable to update it if you need to move carriers because of a country’s lack of access. 

SIM Form Factors 

You could say the differences between SIMs start with the form factor. SIM cards come in various shapes and sizes, and these form factors don’t necessarily determine what kind of software the SIM will have implemented.

Full-Size SIM (1FF)

Comparable in size to a credit card, this is the oldest and the largest card and was predominantly used for early-generation car phones. Still, advancements in miniaturization technology have now made this form factor redundant.

Mini SIM (2FF)

While Mini SIM cards, also known as 2FF SIMs, may be considered dated, they remain relevant, particularly in specific IoT devices. For instance, 2G-based GPS trackers often utilize the 2FF form factor. The 2FF SIM’s ongoing use in such applications highlights its durability and the technology’s ability to serve specific needs even as the industry evolves.

Micro SIM (3FF)

The Micro SIM, or 3FF SIM, emerged with smartphones and devices requiring even smaller components. Its compact size allowed device manufacturers to devote more space to other elements like larger batteries or additional circuitry—this advanced smartphone capabilities include longer battery life and improved performance.

Nano SIM (4FF)

The Nano SIM, or the 4FF SIM, is currently the smallest plastic SIM card available, where the plastic and the chip are nearly identical. While the 4FF is the tiniest among plastic SIM cards, MFF2-embedded SIMs also present themselves as compact physical form factors, albeit integrated directly into the device’s circuitry. The Nano SIM design reflects the ongoing trend toward miniaturization, enabling even thinner and more feature-rich devices.

Conclusion 

  • eSIMs represent a major shift in the way that we utilize our mobile devices.
  •  Whether during travel or locally, eSIM empowers mobile users to easily have multiple plans that work simultaneously on the same device. 
  • This will help businesses become more streamlined and allow individuals to be more flexible.
