I am currently running a business which entails I make lot of calls to different numbers (all networks) and the bill accrued at the end of the month on calls is tearing my profit apart.
I've opted from one tariff plan to the other but d bill is still excruciating

Any idea of what network/plan I should be using?
Note: I don't av a fixed set of numbers I will be calling, so family n friend is not an option.

God bless u as u share.
