wifi password needed for orange livebox

i can connect to my boyfriends wifi easily but for mine i have trouble. it says it requires a password which i thought was the long number on the bottom of the box (e783 ad57 etc etc) but it appears that thats not the password. is there something i'm missing here.

also if i ignore the wifi it tells me it could not activate a cellular data network, that i am not subscribed to one. what does this mean exactly that i am not subscribed. just looked on help here and the little pic i have next to my carrier is a circle looks like a polo mint. not sure if this is one of the 3 pics needed to connect to the internet or not.

i have a 2g iphone and am on pay as you go. will get free text and web on the 23rd if that makes a difference, currently only get 300 free messages (its an old sim card).

thanks
