An eSIM (embedded SIM) is a digital version of the physical SIM card you usually slide into your phone. Instead of a removable plastic sim card chip, the SIM technology is built directly into your device’s hardware. Esim is one of the fast growing technology in Telcom industry. In future wont be any physical sim card.
What exactly is an eSIM?
An eSIM is a small chip inside your phone that acts just like a physical SIM card. It holds your cellular data plan and connects you to your mobile network, but it cannot be removed. You activate it by downloading a “profile” from your carrier. You can swap the esim from one mobile to another mobile.
How does an eSIM work?
It works through software rather than hardware swaps. When you sign up for a mobile plan:
- Your carrier sends you a QR code or a digital activation link.
- You scan the code with your phone.
- Your phone “installs” the network settings onto the built-in chip.
- You are instantly connected to the network without needing a physical card.
Keep in Mind : Before buying sim card you have check the you mobile compatibility. Old device wont support the esim.
