As security protocols evolve, older V5 methods might not work on newer, updated firmware. Alternatives to Factory Unlock Codes

Turn off your device, remove the original carrier SIM, and insert a SIM card from a different provider.

If eligible, the carrier will request the V5 code from Huawei's backend database on your behalf and email it to you within 3 to 7 business days.

Some very new or highly customized Huawei routers might require updated firmware before they accept a V5 code.
