I think they should start reusing numbers that are dormant. There are many, lets do math:

considering 07 is constant, that leaves 8 numbers with 10 choices for each.

10 choices for each number raised by a power of 8 is 100 million.

Safaricom has 5 selections (070, 071, 072, 074, 079)

This means that safaricom has 100 million multiplied by 5

this amounts to 500 million.

We are not that many in Kenya, unless these Telcos are leaving unused combinations for many other reasons (that’s around 452 million unused numbers, assuming even one year olds have saf lines).

Someone correct me if am wrong

**Update:**

Am wrong due to a minor error, cuz kama ni 072, itabaki tu 072.

so, that leaves 7 possible numbers with 10 choices each

hence; 10 raised to power 7 is 10 million.

Multiplied by 5, that 50 million.

Assuming even 1 day olds have lines, that means there 2 million unused numbers kwa safaricom, waache mchezo
