Just thought I should share with those who would want to save money in small amounts but think it's too small 4 the bank.

You only need One1Card to recharge it all!
One1Card is the only scratch card in the world that allows you to recharge multiple services…and it’s available right here in Nigeria. Now with customizable design options, this is the product that makes us the King of Recharge!
How it works
One1Card uses service provider IDs (SPID) to recharge multiple accounts. You can recharge your desired account in two simple steps:
1. Scratch the PIN surface gently.
2. Dial:
For mobile accounts: *979*PIN#
For non-mobile accounts: *979*SPID*PIN*Account Number#
One1Card active SPIDs
NOTE: Mobile SPIDs are only required when you wish to recharge a third party line from yours.
