The SIM (Subscriber Identity Module) is a card that allows your phone to connect to a cellular network. The eSIM (embedded SIM) is a card that is built into your phone.
SIM vs eSIM
A SIM card is a small chip that allows your phone to connect to a specific network. An eSIM is an embedded SIM card that is built into your phone.
The main difference between a SIM card and an eSIM is that a SIM card is a physical card that needs to be inserted into your phone, while an eSIM is a virtual card that is stored on your phone.
If you have a phone with a SIM card, you can only use one network at a time. If you have a phone with an eSIM, you can use multiple networks.
If you're planning to travel, it's important to check whether your phone has a SIM card or an eSIM. Many countries require you to have a SIM card in order to use their networks. If your phone only has an eSIM, you may not be able to use it in those countries.

How do SIM and eSIM work?
A SIM card is a physical card that goes into your phone and stores your information, while an eSIM is a digital card that is stored on your phone and doesn’t need a physical card. Both SIM cards and eSIMs can be used to store your data and connect you to a mobile network, but there are some key differences between the two.
One of the biggest differences between SIM cards and eSIMs is that SIM cards are physical cards that need to be inserted into your phone, while eSIMs are digital cards that are stored on your phone. This means that you don’t need a physical SIM card to connect to a mobile network if you have an eSIM.
Another difference between SIM cards and eSIMs is that SIM cards are assigned to a specific mobile network, while eSIMs can be swapped between different mobile networks. This means that you can use an eSIM to connect to any mobile network that supports eSIMs, while you’ll need a different SIM card for each mobile network you want to connect to if you’re using SIM cards.
Finally, SIM cards are usually tied to a specific phone number, while eSIMs can be used with multiple phone numbers. This means that you can have multiple phone numbers associated with your eSIM, which can be useful if you want to have separate numbers for work and personal use.
The benefits of eSIM
An eSIM is a digital SIM that allows you to activate a cellular plan from your carrier without having to use a physical SIM card. Many newer phones come with eSIM support, and it’s slowly becoming more common.
There are a few benefits of using an eSIM over a physical SIM card. For one, it’s more convenient since you don’t have to carry around a physical card. And if you travel internationally, you can easily add a local SIM card to your phone without having to swap out your physical SIM.
One downside of eSIMs is that not all carriers support them. So, if you’re looking to switch to a carrier that uses eSIMs, make sure they’re supported. Additionally, if you ever need to replace your phone, you’ll need to make sure the new phone also supports eSIMs.
How to use an eSIM
An eSIM is a digital SIM that allows you to activate a cellular plan from your carrier without having to use a physical SIM card. To use an eSIM, you'll need a device that supports eSIMs and a carrier that offers eSIM plans.
If your device supports eSIM, you can usually activate it by scanning a QR code or downloading a carrier profile. Once your eSIM is activated, you can use it just like a regular SIM card.
Some carriers may require you to use a physical SIM card for your first activation, but you should be able to switch to an eSIM after that. If you're traveling, you may be able to use an eSIM from a local carrier to avoid roaming charges.
eSIMs are still relatively new, so not all carriers and devices support them. However, support is growing, and we expect eSIMs to eventually replace physical SIM cards entirely.
