Ciphering comes when two service providers share the same network. They do that to keep costs down in low density areas. Ciphering codes the bandwidth so that it may not interfere with the other service providers.
That means, you are in a non secure internet page, as on the PC. Don't send passwords, don't make money transfers or so in such cases...
That is because you using a very old SIM card whereas the phone software is new which requires ciphering. You should use another SIM card and this error won`t come.
Nice day
