I think the top up / buy goodybags sections of the site should be made free to access, so when credit is out we can top up without finding another computer or wifi signal. I buy airtime vouchers, and I know you can put them on over the phone, but then when you go online to buy a goodybag with it, some credit goes and there isn't enough credit left. You could do this with my old O2 dongle, so it must be possible? Cheers
The giffgaff.com pages, and the community pages, are already free. If you are using the Opera Mini browser then it will not be free because that browser works by using their server to read the free page, then send you a compressed version from the non-free server. Same applies with any browser that uses a similar system, like Google Chrome in economy mode. Also if you have a security app that inspects pages before allowing you to see them.
