The £5 goodybag is brilliant for a light user although if you are a bit more of a heavy user then I suggest looking at the £10 goodybag or even the £7.50 goodybag. The only advangage you get with the £5 goodybag is the extra minutes.
At the end of the day it all depends on you usage of mins, txts and data.
It really depends on the person
The hokey cokey is very good for low users who use their phone mostly for calls. Any cross network incoming call will give them an extra minutes of call time.
The 20MB was added in to the original bag offering after much demand for a little bit of data for checking emails if necessary.
If someone uses a lot of texts or data then they would have to move up to the £10 goodybag.
Wherever I go, I get wifi and only make calls outside of giffgaff to parents asking how they are. Is this goodybag really worth £5?
Text 'plan' to 2020 and you can get your idealised usage plan and recommended goodybag. It can take a few minutes for it to be sent to your phone so just be patient
