iPhones that support 2 SIMs work using a Dual SIM setup that includes a nano-SIM and an eSIM. This allows you to have two phone numbers or two different service plans on the same device. You can use one number for personal calls and another for business, or have one local and one international carrier plan to avoid roaming charges. To activate your eSIM, you typically need to scan a QR code provided by your carrier or enter a few details manually into your phone's settings under 'Cellular' or 'Mobile Data.'
