For all Huawei, the SIM unlock code is available, meaning Huawei 506HW can easily be unlocked with the unlock code. This is an easy and safe way through IMEI to unblock Huawei. You can unlock all Huawei 506HW devices worldwide on any network. You can use all GSM SIM cards anywhere in the world, regardless of region, once the restriction has been removed.
Only a 15-digit IMEI is necessary to unlock your phone/modem/router. By calling *#06# on the phone, the 15-digit IMEI can be found. For a modem/router, from its settings, you can verify the correct IMEI.
The unlocking of the Huawei 506HW by code does not prevent warranty. This is the method recommended by the maker of Huawei to unlock by code. The unlocking code for Huawei 506HW is from the manufacturer’s or network provider’s database, which means it will work 100%. Depending on the phone, you can get up to 04 codes for Huawei 506HW from the database, including:-
NCK – Network code for eliminating the primary network restriction of Huawei 506HW.
SPCK - Service Provider Code or Subset Unlock PIN to delete the network cap from the network subset (e.g., Tesco in Great Britain).
SIMLock Block Unlock Reset Key – If you have already attempted to use too many wrong codes on your Huawei 506HW, a reset key is used to reset the phone code counter.
Note:If you order the Huawei modem/router unlock code, you'll just get NCK (Unlock Code).
