How to Use two phone numbers for calls, messages, and data on iPhone

Since Apple has introduced the feature of having dual sims on a single iPhone, the people are looking for the ways to set the networks according to their needs. You can use your numbers according to your ease. As eSIM is a digital SIM that facilitates you to have another cellular number without having a physical SIM.

This article will teach you how to use both of your networks. You can set your cellular network according to your need or the data plan your carrier is offering you. You can make and receive calls, SMS, MMS on both of your cellular network but you can only use your cellular data network at a time.
