I newly acquired Nokia C3, functioning excellent but for one problem. I have attempted setting up email for the previous 2 weeks. It continues giving the similar error "Service Temporarily Unavailable. Try again later." I don't have any problem attaching to the internet- both on Wi-Fi plus on my service supplier's edge network. I am unable to configure not any of the emails (Gmail, yahoo mail and so on). Does anybody know what the trouble is?
