If you have multiple eSIMs active on your iPhone, or you're using Cape alongside another carrier, your iPhone will operate in Dual SIM mode. This mode allows you to use two lines simultaneously - for example, Cape for personal use and another carrier for work or Cape for cellular data and another carrier for calling and texting.
To learn how to configure Dual SIM settings on your iPhone, please refer to Apple’s support article: Use Dual SIM with an eSIM
