My time on giffgaff ive seen many issues with members having browser problems and other problems such as goodybags and credit card purchases and also asking a agent etc etc
Example: Unable to login - Wrong credentials!
As my time ive spent on here and most of all giffgaffs facebook page helping out ive come across solving a lot off issues with what i found out myself a while back but may not work with some cases.
A word of warning before anyone posts it! This may not sort your problem out but dont worry as theres other help and workarounds at hand for you
Hope it help others and feel free to pass the link on
Why not just use the official link for Opera mini / mobile?
Firefox just seems more faster and very reliable with browser issues.. Ive tried them all and even your link browser played up on different things and i found firefox is the best out the lot. Opera mini mobile is also the best to have on your mobile aswel as the results were far better than others
i keep getting the wrong credentials message every time i try to login on my tablet, tried the opera browser and still the same message. no problems using my pc or phone. this is pretty annoying as i brought the tablet as it is more convenient than a pc for surfing. haven't had any problems on all the other sites i need to login to
