adb shell pm enable com.android.stk Exact package name on Huawei may be com.huawei.android.stk or com.android.stk . Check with adb shell pm list packages | grep stk . Does Huawei’s SIM Toolkit Support Dual SIM? Yes. On dual-SIM Huawei phones, each SIM has its own STK instance. You will see two entries in the app drawer (e.g., “SIM Toolkit 1” and “SIM Toolkit 2”) or a single app that lets you choose which SIM to use. Final Verdict SIM Toolkit on Huawei phones is a passive, carrier-dependent tool. It is neither a security risk nor a performance drain. If you don’t use operator services, you can safely hide or disable it. If you rely on carrier-based mobile banking or balance checks, keep it enabled.

For further assistance, contact your mobile operator—since STK content is entirely controlled by the SIM card, not by Huawei.
