Does iPhone 12 Pro have eSIM?
The iPhone 12 Pro does indeed support eSIM technology (in addition to its physical SIM card slot).
An iPhone 12 Pro allows you to use dual SIM functionality: one line with your regular SIM card and another with an eSIM. For travellers, this is especially useful since you can keep your primary number active while adding a local or international data plan via your eSIM, avoiding steep roaming charges.
