The technologies in smartphones are revamping rapidly as new changes are coming to the software and hardware part. Talking about the SIM part, the most significant adaptation we have seen is eSIM card or digital SIM. eSIM can be integrated and used into your device without using the physical SIM.
eSIMs have been around for a while now; still, many of us don’t know how to use them. So today, in this guide, we will share all the steps to use eSIM on your eligible Huawei phone easily.
What is an eSIM Card?
An eSIM is an embedded SIM card that works similarly to the traditional SIM, but no physical card and swapping is required.
eSIM card is a chip that integrates inside your phone and works similar to the NFCs chip used for payment. The eSIM chip is rewritable so that you can decide to change your operator with a single phone call.
However, not all network operators and phones offer eSIM support yet, but maybe things will change in the future.
How eSIM works?
On an eSIM compatible device, you can install the eSIM profile provided by your network provider, and after that, you can buy the data plans when you need them.
The best part about an eSIM card is that you can subscribe to multiple data plans from different network providers and switch between them according to your suitable needs.
As we know, every coin has two sides; similarly, the eSIM has two sides. It has many advantages but some disadvantages.
