Ensuring that the cellular card's active period is maintained is a crucial step for every Tri customer. Neglecting to monitor the active duration of the card can lead to the number entering a grace period, which, if left without topping up, risks permanent blocking by the system.

The importance of maintaining number activity is not just for smooth communication such as phone calls and text messages, but also for digital access security. Given that many banking services, work platforms, and social media accounts are currently integrated with mobile phone numbers, losing access due to an expired card will certainly cause complications for the user.

To make it easier for customers, Tri provides an efficient self-check channel without requiring users to visit a physical store. The first option is to access the official Tri website via a mobile browser, where detailed information regarding card status can be quickly accessed.

In addition to the official website, users can also utilize the bima+ app available on Android and iOS device app stores. This application offers convenient monitoring not only for the active period, but also for remaining quota information and other services in a single integrated interface.
