Don't know if this has already been covered before but a turkish friend showed me this the other day. Only works if you are using Turkcell.
1.type in *131# and then call.
A message comes up showing if you have any free contours in storage. Mine showed 200
2. Go to write messages and type in just the number of contours you require. You don't have to use them all and can save some. You hen send this message to 2255. You will recieve a message back and a little while later you recieve free contours.
Don't know how many times I have deleted messages from Turkcell because I didn't know what they were....if in doubt, give a shout.
thats me......
