The Nokia C20 introduces an all-rounder budget-ranged smartphone with several user-oriented features. The main properties of dual SIM are that the device supports managing two separate telephone numbers onto one phone. Those who want to separate personal and business contacts are among those for whom this is crucial. Other considerations include multiple carriers or cost-related savings when buying data or making calls. This review focuses on all aspects of the Nokia C20 dual SIM settings, including setup, choice, and troubleshooting.
1. Introduction to Dual SIM Functionality
1.1 What is Dual SIM?
The dual SIM allows a mobile phone to perform the services of two SIM cards simultaneously. In simple terms, you can have two numbers and two plans on one phone, which serves various purposes. The main benefits are:
Keeping Work from Personal Calls: One SIM to be used to receive personal calls, the other to receive work calls-an easy way to keep the two communications distinct.
Saving on Costs: Using different call or data plans offered by different carriers, according to the cost advantage.
Increasing Coverage: Use SIM cards from different carriers when your respective area provides better coverage by now.
1.2 Types of Dual SIM Configurations
Dual SIM Standby (DSS): Both SIMs are put on standby and only one can be used at a time. If a call goes through or data session is active on one SIM, the other is unavailable temporarily.
Dual SIM Active: Both SIMs are active and can receive text messages and call alerts at the same time, but one can only be used for outgoing text or call operations.
The Nokia C20 supports a Dual SIM Standby configuration whereby only one SIM can be actively used for call or data at any given moment.
