Huawei is a leading brand in the mobile and networking industry, having manufactured a variety of mobile phones and routers that are widely used worldwide. However, one of the most common issues faced by Huawei users is the inability to use other network carriers due to network restrictions. Fortunately, this can be resolved by unlocking your Huawei device.
Unlocking your Huawei device allows you to use any network carrier anywhere in the world without restrictions. If you are a Huawei user looking to unlock your Huawei 421D, you have come to the right place. In this article, we will provide a step-by-step guide on how to unlock your Huawei device and use any network carrier you desire. Read on to learn more about Huawei unlocking.
Unlocking your phone/modem/router requires only a 15-digit IMEI. To find the 15-digit IMEI, simply dial *#06# on your phone. For a modem/router, verify the correct IMEI from its settings.
Unlocking your device by code does not void the warranty and is the method recommended by Huawei to unlock your device. The unlocking code for your device is retrieved from the manufacturer's or network provider's database, ensuring a 100% success rate. Depending on your device, you may receive up to 4 codes from the database, including:-
- NCK – Network code to eliminate the primary network restriction of your device.
- SPCK – Service Provider Code or Subset Unlock PIN to remove the network cap from the network subset (e.g., Tesco in Great Britain).
- SIMLock Block Unlock Reset Key – If you have attempted to use too many wrong codes on your device, this reset key is used to reset the phone code counter.
Please note that if you order the Huawei modem/router unlock code, you will only receive the NCK (Unlock Code).
