Had a little trip to Bruges this week and was suprised how quickly my £5 credit disappeared. Was very careful with it but now i'm thinking the £1.50 rate could be per connection??
What are the segments that GG charge by? As soon as you connect is that counted as 1MB up to the point you have actually downloaded the full MB...then it jumps to the 2MB price??
This is quite important as it may be worth just leaving your data connected if it's low use rather than connecting and dissconnecting several times esp if it's 1MB per connection.
