Unlocking the Huawei E5336bs-2 allows you to use the device with any mobile carrier, which is especially useful if your router is currently region-locked or restricted to a specific network.  Primary Unlocking Methods 

This is the safest method as it does not involve potentially risky firmware flashes. Insert a different SIM:

• Provide IMEI; service returns NCK. Often paid.
• Success depends on carrier and firmware; some carriers block code-based unlocks.

• Small, pocketable rectangle with a clear OLED/simple LCD and single-button operation. Plastic construction but sturdy for travel.
• SIM slot and microSD slot inside the battery compartment (on many variants). Micro‑USB for charging.
• Typical indicator LEDs/mini-display showing signal, battery, connected users.
