Introduced to secure older 4G modems, routers, and mid-range smartphones. It upgraded the previous V3 structure, rendering older generation calculators obsolete.

Huawei devices, particularly mobile broadband modems (E-series) and routers (B-series), use specific algorithms to generate network unlocking codes.

If you do not want to download software, you can use online calculators for V4/V5:
