How Does eSIM work?

The eSIM is a function that mounts a digital SIM card (an electronic code) on a smartphone without using a physical SIM card. Instead of a physical card, you can think of it as having an electronic certificate. Using this, there is no need for a physical SIM, and you are free from the loss or damage of a physical SIM card. If you use a model that supports both a physical SIM card and an eSIM card, you can use two lines with one phone.

Limitations of an eSim

  • Limitations arise when a phone is to be sold on exclusive terms by which the range is sold for a particular network only and not to all networks. For such cell phones, the eSim becomes inaccessible and cannot be used with them.
  • Some countries require customer information by the country’s regulations. In that case, you have to upload your passport copy and details.
  • Prepaid eSIM (Most eSIM on Airalo) doesn’t provide a phone number. It’s a data-only plan.
  • You may see the Unlimited Data Plan. It’s literally ‘Unlimited’, but there is a certain high-speed data usage limit. When you exceed the limit, you will be limited to a lower speed rate.
  • It’s not refundable.
  • Some products are non-rechargeable and non-refundable. Please, check it before you buy it.
