i put the giff gaff sim into my blackberry and its asking for the network mep code? how do i get this? pls
It sounds like your Blackberry was locked to a different network and the MEP code is an unlock code for the Blackberry, You need to obtain this from a mobile unlocker.
Geti it unlocked from your'e old network or on ebay who are really cheap.
On a lot of nokias it's free+Orange sf is free.
