Africa is moving fast with its communications infrastructure. Mobile services are cheap, too: you can top up your prepaid cellphone with just 2000 TSH (EUR 1) at a time and the network I use costs just 2 euro-cent per SMS or between 0.75 and 9 euro-cent per minute for a national call. But we’ve still got some way to go.
Receiving SMSs two days after they were sent (or not at all) can be a useful alibi sometimes – like when avoiding the persistent messages I get from a male colleague I probably shouldn’t have given my number to. But otherwise it adds to the generally-present sense in Africa that you never know for sure if something has worked or will work or if plans will actually materialise.
