My friend helped me to buy a 6280 from One2Free. All the configuration/connectivity & menu settings are tailored to One2Free. How could we change to Smartone settings as my 2G service plan is from Smartone.
I used to be able to access to the Internet but now couldn't. An error message "Subscribe to data packet first" is returned. Do you know why? Do I need to join 3G package from One2Free?
