It seems the more and more posts I see daily, we always have this daily dilemma of providing settings to a user, but not knowing what device they have, resulting in several hours or days lost where the user hasn't replied, and therefore hasn't got the answer she/he needs, affecting the giffgaff reputation of speedy quality replies.
The option to allow users input their device model and brand is currently optional, however this idea is to make this a requirement upon sign up. This allows us to know what device the user has, and provide better quality answers to all instead of directing them to the standard Giffgaff APN.
This would solve time, and make the experience of giffgaff far better. Giffgaff is mobile network provider, that's the purpose of giffgaff, and so it would be much more efficient to ask for the phone the user has upon sign up.
Implementing this would be easy, simply add another field to the sign up process asking the phone they have, and make it validated to ensure some text has been entered.
