Pay close attention to this section, as you may have noticed the requirements are a bit different from the ones normally needed for a physical SIM. Therefore, the features of this product are also different from the traditional SIM cards.
Most eSIM cards do not offer analog calls, only data. For voice communication, you can use apps such as Skype or WhatsApp.

Some eSIMs set up automatic APNs.
You can add several data plans on your iPhone, this depends on the available memory, although it is only possible to use one at a time.
Some eSIMs allow you to share data.
On your dual SIM iPhone, you can keep your local SIM when you travel to Asia. Remember to configure your iPhone to avoid surprise bills when you get back home.
