What is eSIM?

[Md Kamrul Hasan]

Recently, eSIMs have been making waves as the next step in mobile technology. Embedded-SIM, or eSIM, is a SIM card that can be electronically programmed into a mobile phone without the need for manual insertion. It works just like a regular SIM but does not require a physical card, and only works on devices with pre-installed eSIM support. Grameenphone has officially launched eSIM service in Bangladesh on 1 March 2022. Very few devices currently have eSIM support, and they need to be carrier-enabled for the eSIM to work.
Apple devices such as iPhone XR, iPhone 11 Pro, iPhone 12 and 13 have built-in eSIM support. Versions of Samsung Galaxy S20, S21, Note 20 and Galaxy Fold, as well as Google Pixel 3, 3a, 4, 4a, 5, 5a and 6 Pro also support eSIM.
