GiffGaff would do well to venture into these 2 areas:
1. Pay As You Go tariffs targeted at Ghanaians resident in the UK who keep regular contact with family back home
2. Secondly GiffGaff might wish to consider also mobile money transfer among same group of Ghanaians resident in the UK.
The latter is one of the simplest ways to remit money back home. It has become so popular some high street banks as well as online entities like XE Currency Exchange are actively trading already.
