It is probably one of the most repeated goodybag myths.
There is a fairly easy way to dispel the rumour.
Turn off your mobile data at 23.59 59s. to preserve data allowances. Make a note of your expiring goodybag data allowance, for example it may show an unused balance of 50MB. Make a note of your new unused (say £6) goodybag notionally showing a deducted data allowance of 10MB leaving a 490MB balance at midnight.
Overnight the wheels and cogs at giffgaff, will calculate/audit the amount of data that needs repatriating to your new goodybag and update/adjust/correct your dashboard goodybag data balance to return to 500MB. If you could still see your old goodybag data allowance, it would have been depleted by 10MB from 50MB to an unused and forever lost 40MB.
Refreshing your dashboard page the next morning, will give you the corrected data (unused) allowance of 500MB
