Currently, Robokiller faces limitations when it comes to dual SIM devices. The application can only support one of the two lines on such devices, typically the primary line. It would require a separate subscription to have Robokiller on the secondary line. However, Robokiller might only function optimally on one line, even with two subscriptions.

We're dedicated to enhancing the Robokiller experience for all our users. Rest assured, our team is working hard to provide seamless support for both lines on dual SIM devices in upcoming versions.
