The Huawei E6878 series is Huawei’s flagship 5G portable hotspot lineup, powered by the Balong 5000 7nm multi-mode chipset — the same chip inside the Huawei 5G CPE Pro routers. These pocket-sized devices deliver 5G download speeds up to 1.65 Gbps, support 4K 60fps live streaming, and can even wirelessly charge other devices.

Carriers like Zain, STC, du, Etisalat, Vodafone, and Orange sell these devices locked to their network. Unlocking requires a Version 5 (V5) unlock code — a 16-digit alphanumeric key that permanently removes the SIM restriction.

Frequently Asked Questions
Can I use the E6878 as a power bank after unlocking?
Yes. The E6878-370 Pro’s reverse charging feature (22.5W wired, 15W wireless) works independently of the SIM lock. Unlocking does not affect any device features.
Is the V5 code the same for all E6878 variants?
No. Each V5 code is unique to your IMEI number. A code generated for one E6878 will not work on another. Always provide your exact IMEI when ordering.
My device is locked to Zain — will this work?
Yes. We have a 100% success rate unlocking Zain-locked E6878 devices. The code also works for STC, du, Etisalat, Vodafone, and all other carriers.
Is the unlock permanent?
Yes. The V5 unlock persists through firmware updates, factory resets, and SIM changes.
