Faiba Internet now available on all 4G Bands?

Faiba seems to be now available on all phones?

Faiba 4G network in Kenya only use the 700MHz spectrum dubbed Band 28.

But, now I see they use other bands like the ones used by Airtel.
Its shows as - 63910 4G.

No wonder their data speeds are nowdays shitty

Not all phones. Only phones that support Band 28 and Band 3. Bado hawajaingia Band 20.

Can it work on my redmi 7?

Si hizi news are very stale? Like 6 months stale?
