- They’re both technically “SIMs”
Yes, that’s right, both are SIMs. However, a SIM card is a chip that is physically installed or removed inside your phone with your carrier’s plan. An eSIM (embedded SIM) is built into your phone and digitally downloads your carrier’s plan.

- Easy to transfer to a new phone: If your SIM card and phone are both unlocked, it’s easy to remove and insert your SIM into another phone.
- Easy to get a new number: Some people prefer picking up local SIM cards because they’ll have a local number to make calls and texts.

ืืืชืจืื ืืช ืฉื eSIM
The beauty of eSIM cards is that they're embedded in your device. You don’t need to remove them to switch carriers, and connecting to data is as simple as downloading a prepaid plan. Here's why you might opt for an eSIM:

- Keep your number: If you’ve got Dual SIM technology on your phone (a physical SIM card in addition to eSIM), you’ll be able to make phone calls with your regular number. ืื ืื, ืืืืืช ืืืืฉื ื-eSIM ืชืืคืฉืจ ืืื ืืืฆืข ืฉืืืืช ืืืืฆืขืืช WhatsApp,โ Telegram ืื ืืคืืืงืฆืื ืคืืคืืืจืืช ืืืจืช.

However, when you travel, you might use the data on your eSIM while reserving your physical SIM for the rare instances you need to receive texts or calls, such as in the case of multifactor authentication.

As you can see, there are advantages to using both nano SIMs and eSIMs in your device — it all depends on which technology makes the most sense for you.
