Real-time tracking and automated alerts also help manage unexpected high charges and foster transparency. Additionally, personalized dispute resolution using a customer's usage history enhances loyalty and reduces churn, while proactive management features such as real-time usage tracking and automated alerts inform customers of nearing data thresholds or potential overages, ultimately positioning telecom providers for success in the dynamic telecommunications market.
