Dual SIM Functionality
A standout feature of the Haier M300 is its dual SIM capability. This feature allows users to manage two mobile networks seamlessly. However, while it supports dual SIM usage, it operates without dual stand-by functionality, implying only one SIM can be active at any given time. This would still be beneficial for users who rely on different numbers for personal and business purposes or who need to manage telephone costs across two networks.
