Nokia 6021 I have set the email setting, when I try to retrieve emal I get an error message saying subscribe to gprs first, I don't know what this means

GPRS stands for General packet Radio Service. It is a technology that provides internet facility to mobile phones. To check Emails on your Nokia 6021 you first have to activate GPRS facility on your connection. For activation of GPRS contact your Customer Care number and ask them to activate GPRS facility and to send GPRS settings on your number. After activation of GPRS you can check Emails on your phone after proper email settings.
Hope this will help for sure..cheers:)
