There are three main arguments for why an eSIM is better than a physical one. The first is that since there's no longer any card-swapping involved, you can shift between telcos that much faster. So long as the provider you're changing to supports eSIM, anyway. The second benefit that eSIM offers is that it can effectively turn a single SIM handset into a dual-SIM. Swapping to eSIM will free up the physical card slot inside your device. What happens next is up to you.  Last but not least, eSIM also offers benefits to those using wearables like the Apple Watch as it allows you to share the same mobile number across both your smartphone and select smartwatches.
