What is ByteSIM

Aug 29,2023 | Tim

Welcome to www.bytesim.com if you NEED an eSIM data plan while traveling around the world. 

Now, here we go!


With the development of eSIM technology, more and more people are nourished by its functions and convenience. But after all, it's a new thing that all of us need to know about and master to make it better serve us human beings. Today, we provide the eSIM FAQs and resources for you to enrich your knowledge of eSIM.

What is an eSIM?

Before we get started, we may as well learn about the basic question: eSIM is what?

A digital SIM card, also known as an eSIM or embedded SIM, is embedded inside devices like smartphones, smartwatches, or tablets. eSIMs, unlike traditional physical SIM cards, cannot be removed and can be programmed with multiple mobile network operator (MNO) profiles. Instead of inserting a physical SIM card into your device, you can now digitally download the network profile onto the eSIM.


You can do everything with an eSIM, because it has the same functionality as a physical SIM.

  • Access local data using your mobile network.

  • Make calls and send text messages using your cellular service.

  • Screen, scan, store, search, activate, and download data to your device.

  • Be able to switch your phone line while keeping your number.

  • Never have to worry about being hit with roaming charges

It also owns the merits that physical SIMs do not have:

  • Flexibility: eSIMs allow for multiple network profiles, enabling easy switching between mobile network operators (MNOs) or plans without physically changing SIM cards.

  • Convenience: there is no need to handle physical SIM cards. Activation and switching between profiles can be done digitally and easily.

  • Remote Provisioning: eSIMs allow users to download and activate network profiles remotely without visiting stores.

  • International Roaming: eSIMs can be switched to local network profiles while abroad without purchasing and inserting a physical SIM card.

To check if your device is eSIM-compatible, please refer to our comprehensive list here .
