eSIM vs physical SIM_ How do they compare

A SIM –  traditionally a small plastic card that slots into your mobile phone – is an acronym for ‘subscriber identity module’

It holds information, such as your mobile phone. It allows you to make and receive calls and texts, and use data on your phone.

 SIMS can also store contact and phone numbers which makes switching phones easy. You can take your sim from your old phone and slot it into a new one. 

What is physical SIM: 

The physical sim that you insert into your phones to connect to mobile networks. SIM cards come in different sizes, with the nano SIM being the industry standard today.

They were invented by Giesecke and Devrient, a German smart card manufacturer in 1991. With limited storage capacity, SIM cards easily transfer contact between devices.

What is an eSIM card: 

 Today, embedded SIM cards replace physical SIM cards for connecting to cellular networks. The eSIM is significantly smaller in size than its physical counterpart.

An ESIM is a SIM card that is embedded into a device rather than inserted and removed.

But, the eSIM can still be rewritten, so you can change carriers or phone numbers when needed. It is easier to set up or switch phone numbers and carriers with an ESIM than with a physical SIM card. You no longer need to wait for a physical SIM card to be delivered or deal with the hassle of using the SIM ejector tools. Instead, the process can be done easily over the phone or through an app. 

The main difference between eSIM and physical SIM: 

Here are some key differences : 


  • Embedded into the device’s motherboard.
  • It does not need physical swapping.
  • Can be programmed or changed remotely. 
  • Can store many profiles.
  • Takes up less physical space in the devices.

Physical SIM:

  • Requires physical swapping of the card
  • It cannot be programmed or changed
  • Can only store profile at a  time 
  • It can be used in a wide range of devices 
  •  Can be replaced or if lost or damaged
