How to memery card lock in nokia cell - Nokia 6230

Unfortunately, you cannot save if the list exceeds the limit(on feature phones like Nokia 3310). However you can save your contacts on your sim card. But that too is very limited

You can connect the phone to a computer using the data cable, then copy the data.

you should format your memory card on computer and if you not able you should format using DOS..

using any of these 3 ways,you will lose information,unless you back up to memery card 1st.
type *#7380# is the soft reset,(not always work)
type *#7370# is the hard reset(not always work)
or theres a full format,that will delete all data,,so back your phone +memery up 1st..
switch phone off,1st.then(remember this put your mob bac to when you 1st had it,unless you back up to memery card 1st:)
press * and 3 together ,and keep them pressed,,while you press them,,press power on,,and keep all 3 pressed in untill you see the nokia logo,,,then release just the power on,,keeping the other 2 pressed in,,untill you see mob asking which country.....realse then...that will work on all n series and e series,and any symbian nokia mob.
when mob comes on to main screen,your backup will start installing.
