I was wondering whether people still go under umbrella to pay for calls.

When last did you visit a pay-call centre to make/rent a phone call?

dat stuff died a long tym ago,wen mtn,airtel and glo were using us to shine, then etisalat came, and d rest is history.

Lol, e don tay.. Multilinks and Starcomm

That is now history.

During the era of MTN, econet (airtel) and glo, calls were expensive because the inter connectivity rates charged by these operators were high and as a result they introduced booster, bumper and profit maximizer cards to make more profit by reducing calls by 50% for phone vendors. I remember charging N30/min to any network and N10 for receiving calls after i had pay MTN N9,000 for booster card. Business was booming then especially when customers saw the need to make calls then. I made super profit when receiving calls to settle some expenses and still have more cash but now the story has changed.
People stopped visiting as a result of the following reasons;
1. Call reduction by 80%
2. More persons now own mobile phones and sims
3. You can now make calls at your convenience without waiting for phone vendor to open shop when he or she please
