"As certain governments actively censor or restrict the sites its citizens visit, they often employ trackers who scan IPs tapping into proxy sources, and any that show up in the scan are flagged for a live reviewer to see what the proxy user sees, so depending on what sites they visit, they could get visited by their local law enforcement agency for investigation." via WIKIPEDIA
What does this mean?? :/
If you're in the middle east they've banned facebook etc.., you can use those sites with proxies just fine. but If you're watching something like kiddie porn then that's another story. It all depends on what you're trying to do, no connection is 100% anonymous.

OP ... from what i know about the area you are from .. be very careful
like Mr Apricot said .. if they want to know what you are doing THEY WILL ..period.
for starters if its not bw intensive ..i would use tor and chain it via hma or something ..
if your concern is only that the ISP should not know, then the above method will work fine
