My suggestion is that gigabag users get an email notification when the data allowance of their gigabag is getting low so they are not taken by suprise if all the data allowance is used before the gigabag expires.
The reasons for this request is that iPad and tablet users do not receive the text notifications that are currently sent regarding low remaining data
This will allow people to either add some credit, or cut down on Internet usage and avoid them being left without access to the internet.
At the moment if all of the data allowance is used up, then any credit on the account is used to pay for usage per mg, if a notification were issued when the data is getting low this would help prevent users from inadvertently spending their credit
Apologies if this has already been suggested, I did a search and couldn't find anything too similar
