Root Call SMS Manager Mod APK lets you block unwanted incoming and outgoing calls and text messages.
The app lets you block unwanted incoming and outgoing calls and text messages.
Some features of the app require root access. Root rights are not required to block calls on Android 8 and newer.
The app supports Dual SIM phones. Blocking happens at the system level, so the app doesn't miss the first call, the screen doesn't light up, and no dialer window appears. Features: – Blocks incoming SMS and MMS on Android 4.4 and above without needing a separate SMS processing app. – Blocks outgoing calls and SMS. – Supports Dual SIM phones, letting you set different blocking parameters for each SIM. – Private conversations. Option to replace the incoming caller number.
For calls, you can choose the blocking method: “Reject” or “Do not answer”. For SMS, you can optionally set a text filter (if no filter is set, all SMS from the specified number are blocked). To separate multiple filters, use the symbol “;”. If you place the symbol “!” at the beginning of the filter field, all SMS that do not match the filter will be blocked. To filter numbers, you need to create a list and set it as the current list. The “Do not block” mode disables all blocking functions. The black list blocks all numbers added to it, and you can set blocking parameters for each number. The white list blocks all numbers that are not on it, and blocking parameters come from the list settings. Numbers in the exceptions list are handled by the rules you set, regardless of the current list's settings. When adding a number to a list, you can use a template (“?” stands for any single character, “*” stands for any number of characters). To block hidden numbers, leave the number field empty. You can use regular expressions (they must begin with “^” and end with “$”, available only in the full version). You can also use schedules, which automatically make a chosen list the current list at set times. Free version limitations: – No more than two entries in the list (templates can be used, such as all contacts, all non-contacts, or numbers containing letters). Contact groups and exceptions are not supported. – No scheduler. Important system settings: – Wait after boot (seconds). This delay ensures the phone module is fully activated before the app starts. A typical value is 10 to 40 seconds, though many devices work with zero delay. If blocking doesn't work on the second SIM of your Dual SIM phone, increase this value. – Submode. This option controls hardware features of the device. You may need to choose a submode that makes the app work effectively and keeps the network active after the app starts (reboot). Reboot your phone after changing the submode. For MTK smartphones, choose submode 1. In Settings, under “About,” you can check the current service status. For successful operation, SIM1 (SIM2 for Dual SIM) should show green.
Tasker integration: to use Tasker, add “Start application” as a task, select Root Call Manager, and enter a list name in the data field. This will make the selected list the current list.
