What Is eSIM Card?
An eSIM is a digital SIM card that allows you to get connected to the internet (sometimes with calls/texts). For example, WhatsApp works quite well with data-only eSIMs. You can freely do media sharing, calls, and messages!
Your phone number remains the same, and you can use it as usual. If you get a new phone number, turn off the regular SIM card then.
Usually, 4G eSIMs are enough (50-100 Mbps speed) for you to use with low-cost payment. But if your phone is 5G-compatible, then that will be better for higher speed.
